NOTES TO THE FINANCIAL STATEMENTS

Note 1.Financial statements preparation

This financial report of Westpac Banking Corporation (the Parent Entity), together with its controlled entities (the Group or Westpac), for the year ended 30 September 2025, was authorised for issue by the Board of Directors on 2 November 2025. The Directors have the power to amend and reissue the financial report.

The material accounting policies are set out below and in the relevant notes to the financial statements. The accounting policy for the recognition, derecognition, classification and measurement basis of financial assets and financial liabilities precedes Note 9. These policies have been consistently applied to all the years presented, unless otherwise stated.

a.

Basis of preparation

(i)

Basis of accounting

This financial report is a general purpose financial report prepared in accordance with:

●The requirements for an Authorised Deposit-taking Institution (ADI) under the Banking Act 1959 (as amended);
●Australian Accounting Standards (AAS) and Interpretations as issued by the Australian Accounting Standards Board (AASB); and
●The Corporations Act 2001.

Westpac Banking Corporation is domiciled and incorporated in Australia and is a for-profit entity for the purposes of preparing these financial statements.

The financial report also complies with International Financial Reporting Accounting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and Interpretations as issued by the IFRS Interpretations Committee (IFRIC). It also includes additional disclosures required for foreign registrants by the United States Securities and Exchange Commission (US SEC).

All amounts have been rounded in accordance with ASIC Corporations (Rounding in Financial/Directors’ Reports) Instrument 2016/191, to the nearest million dollars, unless otherwise stated.

Westpac has elected to apply ASIC Corporations (Parent Entity Financial Statements) Instrument 2021/195 and has presented both Parent Entity and Group financial statements in the financial report.

(ii)

Historical cost convention

The financial report has been prepared under the historical cost convention, as modified by applying fair value accounting to financial assets and financial liabilities (including derivative instruments) measured at fair value through income statement (FVIS) or in other comprehensive income (OCI).

(iii)

Standards adopted during the year ended 30 September 2025

No new accounting standards have been adopted by the Group for the year ended 30 September 2025. There have been no amendments to existing accounting standards that have had a material impact to the Group or the Parent Entity.

Note 1. Financial statements preparation (Continued)

(iv)

Business combinations

Business combinations are accounted for using the acquisition method of accounting. Acquisition cost is measured as the aggregate of the fair value at the date of acquisition of the assets given, equity instruments issued or liabilities incurred or assumed. Acquisition-related costs are expensed as incurred (except for those costs arising on the issue of equity instruments which are recognised directly in equity).

Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured at fair value on the acquisition date. Goodwill is measured as the excess of the acquisition cost, the amount of any non-controlling interest and the fair value of any previous Westpac equity interest in the acquiree, over the fair value of the identifiable net assets acquired.

(v)

Foreign currency translation

Functional and presentation currency

The consolidated financial statements are presented in Australian dollars which is the Parent Entity’s functional and presentation currency. The functional currency of offshore entities is usually the main currency of the economy they operate in.

Transactions and balances

Foreign currency transactions are translated into the functional currency of the relevant branch or subsidiary using the exchange rates prevailing at the dates of the transactions. Foreign exchange (FX) gains and losses resulting from the settlement of such transactions and from the translation at year end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement, except when deferred in OCI for qualifying cash flow hedges and qualifying net investment hedges.

Foreign operations

Assets and liabilities of foreign branches and subsidiaries that have a functional currency other than the Australian dollar are translated at exchange rates prevailing on the balance date. Income and expenses are translated at average exchange rates prevailing during the year. Equity balances are translated at historical exchange rates.

The resulting exchange differences are recognised in the foreign currency translation reserve in OCI.

Where Westpac hedges the currency translation risk arising from net investments in foreign operations, the gains or losses on the hedging instruments are also reflected in OCI to the extent the hedge is effective. When all or part of a foreign operation is disposed or borrowings that are part of the net investments are repaid, a proportionate share of such exchange differences is recognised in the income statement as part of the gain or loss on disposal or repayment of borrowing.

(vi)Comparative revisions

Comparative information has been revised where appropriate to conform to changes in presentation in the current year and to enhance comparability.

10    WESTPAC GROUP 2025 ANNUAL REPORT

​

NOTES TO THE FINANCIAL STATEMENTS

Note 1. Financial statements preparation (Continued)

b.Critical accounting assumptions and estimates

Applying Westpac’s accounting policies requires the use of judgement, assumptions and estimates which impact the financial information. The significant assumptions and estimates used are discussed in the relevant notes below:

Note 10         Provision for expected credit losses (ECL)

Note 22         Fair values of financial assets and financial liabilities

Note 25         Provisions, contingent liabilities, contingent assets and credit commitments

Geopolitical developments including in relation to international trade and tariff policies, global tensions and continuing global military conflict, have led to heightened uncertainty as to future economic forecasts and potential impacts on the Group and its customers. Responding to this heightened uncertainty, the Group has increased the weighting of the downside scenario used in the estimate of expected credit losses from 42.5% to 47.5% (refer to Note 10 for further details).

Impact of climate-related risks

Westpac has considered the potential risk of climate change on its financial statements including both physical risks and transition risks. Westpac has concluded that based on the information and methodologies currently used, climate-related risks did not have a material impact on the judgements, assumptions and estimates for the year ended 30 September 2025. This conclusion also reflects that the most significant impacts of climate change are expected to mostly occur beyond the expected life of our exposures.

Key considerations in reaching this conclusion included assessing Westpac’s exposure to:

●higher transition risk industries as a proportion of overall credit exposures; and
●physical risks that may arise from changing weather patterns and extreme weather events.

Climate change represents a significant source of uncertainty in the medium to long term which may affect our financial statements in the future. Measuring the financial impact of climate change continues to evolve and Westpac will continue to improve its climate scenario analysis and stress testing modelling to assess these potential impacts.

Details of the provision for ECL, including overlays held in relation to climate-related risks, are provided in Note 10.

c.

Future developments

(i)

Accounting standards

AASB 9 Financial Instruments: Recognition and Measurement (AASB 9) became effective for the Group for the financial year ended 30 September 2019. When adopted, as permitted by the standard, the Group elected to continue to comply with the hedge accounting requirements under AASB 139. The Group intends to adopt the hedge accounting requirements of AASB 9 prospectively for the financial year beginning 1 October 2025. All the Group’s existing hedge accounting relationships will continue to qualify for hedge accounting. It is intended to introduce new hedge accounting relationships under AASB 9 for our foreign currency term funding over cross currency basis risk. This will result in associated costs of hedging being reflected in a new cost of hedging reserve (COHR) rather than through the income statement. The quantum of this impact will be based on the valuation of the derivatives at the time.

AASB 18 Presentation and Disclosure in Financial Statements (AASB 18) was issued on 7 June 2024 and will be effective for the 30 September 2028 year end unless early adopted. AASB 18 will replace AASB 101 Presentation of Financial Statements. This standard will not change the recognition and measurement of items in the financial statements, but will impact the presentation and disclosure in the financial statements, including:

●new categories and subtotals in the income statement to enhance comparability;
●enhancing the disclosure of management defined performance measures; and
●changes to the grouping of information in the financial statements to provide more useful information.

Westpac is continuing to assess the impact of adopting AASB 18.

AASB 2024-2 Amendments to Australian Accounting Standards – Classification and Measurement of Financial Instruments (AASB 2024-2) was issued on 29 July 2024 and is effective for the 30 September 2027 year end unless early adopted.

The amendments include:

●changes to disclosures for investments in equity instruments designated at fair value through other comprehensive income and additional disclosures for financial instruments with contingent features that do not relate directly to basic lending risks and costs;
●guidance on derecognition of financial liabilities criteria when using an electronic payments system; and
●guidance on assessing contractual cash flow characteristics of financial assets with environmental, social and corporate governance (ESG) and similar features.

Westpac is continuing to assess the impact of adopting AASB 2024-2.

(ii)Other developments

AASB S1 General Requirements for Disclosure of Sustainability-related Financial Information (AASB S1) and AASB S2 Climate-related Disclosures (AASB S2) were issued by the AASB on 20 September 2024.

These standards are Australian Sustainability Reporting Standards which are issued by the AASB and set out the sustainability-related and climate-related financial disclosures for sustainability reports and general purpose financial reports. The main features of these standards are described below.

AASB S1

This Standard applies to reporting sustainability-related financial information across a range of possible sustainability topics, including climate-related financial disclosures that form part of an entity’s general-purpose financial reporting. It sets out general requirements for the presentation of those disclosures, guidelines for their structure and minimum requirements for their content (including disclosures on governance, strategy, risk management, and metrics and targets), the location of disclosures, the timing of reporting and disclosures relating to judgements, uncertainties and errors. AASB S1 is a voluntary standard and provides guidance on the application of AASB S2.

AASB S2

This standard sets out disclosure requirements in general purpose financial reports about climate-related risks and opportunities that could reasonably be expected to affect the entity’s cash flows, access to finance or cost of capital over the short, medium or long term. The main climate-related financial disclosure requirements relate to four key areas of governance, strategy, risk management, and metrics and targets. The standard also requires disclosures on scenario analysis and greenhouse gas emissions (Scope 1, 2 and 3). General requirements such as the conceptual foundations for reporting such information, the location of disclosures, the timing of reporting and disclosures relating to judgements, uncertainties and errors are also provided. The Group is continuing to progress the implementation of AASB S2 which becomes effective for the Group for the 30 September 2026 year end.

NOTES TO THE FINANCIAL STATEMENTS

FINANCIAL PERFORMANCE

Note 2.Segment reporting

Accounting policy

​

Operating segments are presented on a basis consistent with information provided internally to Westpac’s key decision makers and reflect the management of the business, rather than the legal structure of Westpac.

Internally, Westpac uses an adjusted AAS measure of performance which excludes Notable Items in assessing the financial performance of its segments.

Notable Items are items that management believes are not reflective of Westpac’s ongoing business performance and are grouped into the following broad categories:

●
Unrealised fair value gains and losses on economic hedges that do not qualify for hedge accounting
●
Net ineffectiveness on qualifying hedges
●
Large items that are not reflective of Westpac’s ordinary operations. In individual reporting periods large items may include:

–

Provisions for remediation, litigation, fines and penalties

–

The impact of asset sales and revaluations

–

The write-down of assets (including goodwill and capitalised software)

–

Restructuring costs

The performance of each operating segment reflects internal charges, transfer pricing adjustments and revenue and expenses resulting from inter-segment transactions. These are eliminated on consolidation in the Group Businesses segment. Inter-segment pricing is determined on an arm’s length basis.

​

Notable Items presentation

In prior years, Segment information was presented with a separate line item for Notable Items impacting Operating income and Operating expense for each segments. To align with internal presentation in 2025, Segment results are presented excluding Notable Items, and reconciled at a Group level to the Statutory Profit. Accordingly, prior period presentations have been reclassified to reflect current presentation.

Reportable operating segments

We are one of Australia’s leading providers of banking and selected financial services, operating under multiple brands, and predominantly in Australia and New Zealand, with a small presence in Europe, North America, Asia and the Pacific. We operate significant online capability supported by an extensive branch and ATM network, call centres and relationship bankers. Our operations comprise the following key segments:

●Consumer provides banking products and services to customers in Australia through three lines of business consisting of mortgages, consumer finance and cash and transactional banking.
●Business & Wealth comprises Business Banking for customers generally up to $200 million in exposure, Wealth Management, Private Wealth and Westpac Pacific.
●Institutional delivers a broad range of financial products and services to corporate, institutional and government customers.
●New Zealand provides banking, and wealth products and services for consumer, business and institutional customers in New Zealand.
●Group Businesses includes Treasury, Enterprise services and other costs not directly attributable to segments including Corporate Affairs, Finance and HR services, a portion of enterprise technology costs related to UNITE in prior periods, certain customer remediation expenses and enterprise provisions. It also includes Group-wide consolidation entries.

Changes in Segment Composition

In 2025, the following changes to Segment results were applied:

●The merchants services business was transferred from Business & Wealth to Institutional given strategic alignment with the management of payments infrastructure;
●The contribution from the auto finance portfolio, which was sold in March 2025, was transferred from Business & Wealth to Group Businesses; and
●The realignment of Consumer, Business & Wealth and Institutional Human Resources and Finance function expenses to Group Businesses.

NOTES TO THE FINANCIAL STATEMENTS

Note 3.Net interest income and average balance sheet and interest rates

Net interest income

Accounting policy

​

Interest income and interest expense for all interest earning financial assets and interest bearing financial liabilities at amortised cost or FVOCI, detailed within the table below, are recognised using the effective interest method. Net income from treasury’s interest rate and liquidity management activities and the cost of the Bank levy are included in net interest income.

The effective interest method calculates the amortised cost of a financial instrument by discounting the financial instrument’s estimated future cash receipts or payments to their present value and allocates the interest income or interest expense, including any fees, costs, premiums or discounts integral to the instrument, over its expected life.

Interest income is calculated based on the gross carrying amount of financial assets in stages 1 and 2 of the Group’s ECL model and on the carrying amount net of the provision for ECL for financial assets in stage 3.

Note 3.Net interest income and average balance sheet and interest rates (Continued)

Calculation of variances

Net interest income may vary from year to year due to changes in the volume of, and interest rates associated with, interest earning assets and interest bearing liabilities. Changes due to volume and rates are calculated at the balance sheet line items. Disaggregation into product classification includes the impact of compositional changes (mix) from prior periods. As such, calculations at a product level will result in a different outcome and will not sum to the balance sheet line item.

The following table allocates the change in net interest income between changes in volume and interest rate for those assets and liabilities:

●Volume changes are determined based on the movements in average asset and liability balances; and
●Interest rate changes are determined based on the change in interest rate associated with those assets and liabilities. Variances that arise due to a combination of volume and interest rate changes are allocated to interest rate changes.

Note 4.Non-interest income

Accounting policy

​

Non-interest income includes net fee income, net wealth management, trading income and other income.

Net fee income

When another party is involved in providing goods or services to a Westpac customer, Westpac assesses whether the nature of the arrangement with its customer is as a principal provider or an agent of another party. Where Westpac is acting as an agent for another party, the income earned by Westpac is the net consideration received (i.e. the gross amount received from the customer less amounts paid to a third-party provider). As an agent, the net consideration represents fee income for facilitating the transaction between the customer and the third-party provider with primary responsibility for fulfilling the contract.

Fee income

Fee income is recognised when the performance obligation is satisfied by transferring the promised good or service to the customer. Fee income includes facility fees, transaction fees and other non-risk fee income.

Facility fees include certain line fees, annual credit card fees and fees for providing customer bank accounts. They are recognised over the term of the facility/period of service on a straight-line basis.

Transaction fees are earned for facilitating banking transactions such as FX fees, telegraphic transfers and issuing bank cheques. Fees for these one-off transactions are recognised once the transaction has been completed. Transaction fees are also recognised for credit card transactions including interchange fees net of scheme charges. These are recognised once the transaction has been completed; however, a component of interchange fees received is deferred as unearned income as Westpac has a future service obligation to customers under Westpac’s credit card reward programs.

Other non-risk fee income includes advisory and underwriting fees which are recognised when the related service is completed.

Income which forms an integral part of the effective interest rate of a financial instrument is recognised using the effective interest method and recorded in interest income (for example, loan origination fees).

Fee expenses

Fee expenses include incremental external costs that vary directly with the provision of goods or services to customers. An incremental cost is one that would not have been incurred if a specific good or service had not been provided to a specific customer. Fee expenses which form an integral part of the effective interest rate of a financial instrument are recognised using the effective interest method and recorded in net interest income. Fee expenses include the costs associated with credit card loyalty programs which are recognised as an expense when the services are provided on the redemption of points as well as merchant transaction costs.

Net wealth management income

Wealth management fees earned for the ongoing management of customer funds and investments are recognised when the performance obligation is satisfied which is over the period of management.

Trading income

●
Realised and unrealised gains or losses from changes in the fair value of trading assets, liabilities and derivatives are recognised in the period in which they arise (except day one profits or losses which are deferred, refer to Note 22); and
●
Net income related to Treasury’s interest rate and liquidity management activities is included in net interest income.

Other income - dividend income

●
Dividends on quoted shares are recognised on the ex-dividend date; and
●
Dividends on unquoted shares are recognised when the Company’s right to receive payment is established.

NOTES TO THE FINANCIAL STATEMENTS

​

Note 6.Impairment charges

Accounting policy

​

Impairment charges are based on an expected loss model which measures the difference between the current carrying amount and the present value of expected future cash flows taking into account past experience, current conditions and multiple probability-weighted macroeconomic scenarios for reasonably supportable future economic conditions. Further details of the calculation of ECL and the critical accounting assumptions and estimates relating to impairment charges are included in Note 10.

Impairment charges are recognised in the income statement, with a corresponding amount recognised as follows:

●
Loans, debt securities at amortised cost and due from subsidiaries balances: as a reduction of the carrying value of the financial asset through an offsetting provision account (refer to Note 10);
●
Debt securities at FVOCI: in reserves in OCI with no reduction of the carrying value of the debt security (refer to Note 26); and
●
Credit commitments: as a provision (refer to Note 25).

Uncollectable loans

A loan may become uncollectable in full or part if, after following Westpac’s loan recovery procedures, Westpac remains unable to collect that loan’s contractual repayments. Uncollectable amounts are written off against their related provision for ECL, after all possible repayments have been received.

Where loans are secured, amounts are generally written off after receiving the proceeds from the security, or in certain circumstances, where the net realisable value of the security has been determined and this indicates that there is no reasonable expectation of full recovery, write-off may be earlier. Unsecured consumer loans are generally written off after 180 days past due.

Westpac may subsequently be able to recover cash flows from loans written off. In the period which these recoveries are made, they are recognised in the income statement.

Note 7.Income tax

Accounting policy

​

The tax expense for the year comprises current and deferred tax. Tax is recognised in the income statement, except to the extent that it relates to items recognised directly in OCI, in which case it is recognised in the statement of comprehensive income. As the Bank levy is not a levy on income, it is not included in income tax. It is included in interest expense in Note 3.

Current tax is the tax payable for the year using enacted or substantively enacted tax rates and laws for each jurisdiction. Current tax also includes adjustments to tax payable for previous years.

Deferred tax accounts for temporary differences between the carrying amounts of assets and liabilities in the financial statements and their values for taxation purposes.

Deferred tax is determined using the enacted or substantively enacted tax rates and laws for each jurisdiction which are expected to apply when the assets will be realised or the liabilities settled.

Deferred tax assets and liabilities have been offset where they relate to the same taxation authority, the same taxable entity or group, and where there is a legal right and intention to settle on a net basis.

Deferred tax assets are recognised to the extent that it is probable that future taxable profits will be available to utilise the assets.

Deferred tax is not recognised for the following temporary differences:

●
The initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither the accounting nor taxable profit or loss;
●
The initial recognition of goodwill in a business combination; and
●
Retained earnings in subsidiaries which the Parent Entity does not intend to distribute for the foreseeable future.

The Parent Entity is the head entity of a tax consolidated group with its wholly owned Australian subsidiaries. All entities in the tax consolidated group have entered into a tax sharing agreement which, in the opinion of the Directors, limits the joint and several liabilities in the case of a default by the Parent Entity.

Current and deferred tax are recognised using a ‘group allocation basis’. As head entity, the Parent Entity recognises all current tax balances and deferred tax assets arising from unused tax losses and relevant tax credits for the tax-consolidated group. The Parent Entity fully compensates/is compensated by the other members for these balances.

Pillar Two legislation has been enacted or substantively enacted in certain jurisdictions in which Westpac operates and became effective for the Group for the financial year beginning 1 October 2024.

The Group has recognised a current tax expense for Pillar Two top-up tax obligations of $7 million for the year ended 30 September 2025 which is included in the above total income tax expense. The Group has applied the mandatory temporary exception from recognising and disclosing Pillar Two deferred taxes under AASB 112.

Note 8.Earnings per share

Accounting policy

​

Basic earnings per share (EPS) is calculated by dividing the net profit attributable to owners of WBC by the weighted average number of ordinary shares on issue during the period. These numbers are adjusted for treasury shares and the dividends related to treasury shares. Diluted EPS is calculated by adjusting the basic EPS by assuming all dilutive potential ordinary shares are converted. Refer to Note 14 and Note 31 for further information on the potential dilutive instruments.

a.

Restricted shares are explained in Note 31. Some shares under the RSP and EIP restricted shares have not vested and are not outstanding ordinary shares but do receive dividends. These RSP and EIP dividends are deducted to show the profit attributable to ordinary shareholders.

b.

The Group has issued convertible loan capital which may convert into ordinary shares in the future (refer to Note 14 for further details). These convertible loan capital instruments are potentially dilutive instruments, and diluted EPS is therefore calculated as if the instruments had been converted at the beginning of the year, or at the instruments’ issue date, where issuance occurred partway through the year.

FINANCIAL ASSETS AND FINANCIAL LIABILITIES

Accounting policy

​

Recognition

Financial assets and financial liabilities, other than regular way transactions, are recognised when Westpac becomes a party to the terms of the contract, which is generally on settlement date (the date payment is made or cash advanced). Purchases and sales of financial assets in regular way transactions are recognised on trade date (the date on which Westpac commits to purchase or sell an asset).

Derecognition

Financial assets are de-recognised when the rights to receive cash flows from the asset have expired, or when Westpac has either transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full under a ‘pass through’ arrangement and transferred substantially all the risks and rewards of ownership.

There may be situations where Westpac has partially transferred the risks and rewards of ownership but has neither transferred nor retained substantially all the risks and rewards of ownership. In such situations, where Westpac retains control of the transferred asset, it will continue to be recognised in the balance sheet to the extent of Westpac’s continuing involvement in the asset.

Financial liabilities are de-recognised when the obligation is discharged, cancelled or expires. Where an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, the exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability, with the difference in the respective carrying amounts recognised in the income statement.

The terms are deemed to be substantially different if the discounted present value of the cash flows under the new terms (discounted using the original effective interest rate) is at least 10% different from the discounted present value of the remaining cash flows of the original financial liability. Qualitative factors such as a change in the currency the instrument is denominated in, a change in the interest rate from fixed to floating and conversion features are also considered.

Classification and measurement basis

Financial assets

Financial assets are grouped into the following classes: cash and balances with central banks, collateral paid, trading securities and financial assets measured at FVIS, derivative financial instruments, investment securities, loans and other financial assets.

Financial assets are classified based on a) the business model within which the assets are managed, and b) whether the contractual cash flows of the instrument represent solely payment of principal and interest (SPPI).

Westpac determines the business model at the level that reflects how groups of financial assets are managed. When assessing the business model Westpac considers factors including how performance and risks are managed, evaluated and reported and the frequency and volume of, and reason for, sales in previous periods and expectations of sales in future periods.

When assessing whether contractual cash flows are SPPI, interest is defined as consideration primarily for the time value of money and the credit risk of the principal outstanding. The time value of money is defined as the element of interest that provides consideration only for the passage of time and not consideration for other risks or costs associated with holding the financial asset. Terms that could change the contractual cash flows so that they may not meet the SPPI criteria include contingent and leverage features, non-recourse arrangements, and features that could modify the time value of money.

Debt instruments

If the debt instruments have contractual cash flows which represent SPPI on the principal balance outstanding they are classified at:

●
Amortised cost if they are held within a business model whose objective is achieved through holding the financial asset to collect these cash flows; or
●
FVOCI if they are held within a business model whose objective is achieved both through collecting these cash flows or selling the financial asset; or
●
FVIS if they are held within a business model whose objective is achieved through selling the financial asset.

​

​

​

​

30    WESTPAC GROUP 2025 ANNUAL REPORT

​

NOTES TO THE FINANCIAL STATEMENTS

FINANCIAL ASSETS AND FINANCIAL LIABILITIES (Continued)

​

Debt instruments are classified and measured at FVIS where the contractual cash flows do not represent SPPI on the principal balance outstanding or where it is designated at FVIS to eliminate or reduce an accounting mismatch.

Equity securities

Equity securities are classified and measured at FVOCI where they:

●
Are not held for trading; and
●
An irrevocable election is made by Westpac.

Otherwise, they are measured at FVIS.

Financial liabilities

Financial liabilities are grouped into the following classes: collateral received, deposits and other borrowings, other financial liabilities, derivative financial instruments, debt issues and loan capital.

Financial liabilities are measured at amortised cost if they are not held for trading or designated at FVIS, otherwise they are measured at FVIS.

Financial assets and financial liabilities measured at FVIS are recognised initially at fair value. All other financial assets and financial liabilities are recognised initially at fair value plus or minus directly attributable transaction costs, respectively.

Further details of the accounting policy for each category of financial asset or financial liability mentioned above are set out in the note for the relevant item.

Westpac’s policies for determining the fair value of financial assets and financial liabilities are set out in Note 22.

Lending and credit risk

Note 9.Loans

Accounting policy

​

Loans are financial assets initially recognised at fair value plus directly attributable transaction costs and fees.

Loans are subsequently measured at amortised cost using the effective interest method where they have contractual cash flows which represent SPPI on the principal balance outstanding and they are held within a business model whose objective is achieved through holding the loans to collect these cash flows. They are presented net of any provision for ECL.

Loans are subsequently measured at FVIS where they do not have cash flows which represent SPPI, are held within a business model whose objective is achieved by selling the financial asset, or are designated at FVIS to eliminate or reduce an accounting mismatch.

Refer to Note 22 for balances which are measured at fair value and amortised cost.

Loan products that have both mortgage and deposit facilities are presented gross in the balance sheet, segregating the asset and liability component, because they do not meet the criteria to be offset. Interest earned on these products is presented on a net basis in the income statement as this reflects how the customer is charged.

Note 10.Provision for expected credit losses

Accounting policy

​

Note 6 provides details of impairment charges.

Impairment applies to all financial assets at amortised cost, lease receivables, debt securities measured at FVOCI, due from subsidiaries and credit commitments.

The ECL is recognised as follows:

●
Loans (including lease receivables), debt securities at amortised cost and due from subsidiaries: as a reduction of the carrying value of the financial asset through an offsetting provision account (refer to Note 9 and Note 17);
●
Debt securities at FVOCI: in reserves in OCI with no reduction of the carrying value of the debt security itself (refer to Note 17 and Note 26); and
●
Credit commitments: as a provision (refer to Note 25).

Measurement

Westpac calculates the provision for ECL based on a three-stage approach. The provision for ECL is a probability-weighted estimate of the cash shortfalls expected to result from defaults over the relevant time frame. They are determined by evaluating a range of possible outcomes and taking into account the time value of money, past events, current conditions and forecasts of future economic conditions.

The models use three main components to determine the ECL (as well as the time value of money) including:

●
Probability of default (PD): the probability that a counterparty will default;
●
Loss given default (LGD): the loss that is expected to arise in the event of a default; and
●
Exposure at default (EAD): the estimated outstanding amount of credit exposure at the time of the default.

Model stages

The three stages are as follows:

Stage 1: 12 months ECL – performing

For financial assets where there has been no significant increase in credit risk since origination, a provision for 12 months ECL is recognised.

Stage 2: Lifetime ECL – performing

For financial assets where there has been a significant increase in credit risk since origination but where the asset is still performing, a provision for lifetime ECL is recognised. The indicators of a significant increase in credit risk are described on the following page.

Stage 3: Lifetime ECL – non-performing

Financial assets in Stage 3 are those that are in default. This is aligned to the regulatory definition of default applied in the calculation of credit risk weighted assets. A default occurs when:

●
Westpac considers that the customer is unable to repay its credit obligations in full, irrespective of recourse by Westpac to actions such as realising security. Indicators include a breach of contract with Westpac such as a default on interest or principal payments, a borrower experiencing significant financial difficulties or observable economic conditions that correlate to defaults on an individual basis; or
●
The customer is more than 90 days past due on any material credit obligation.

A provision for lifetime ECL is recognised on these financial assets.

Collective and individual assessment

Financial assets that are in Stages 1 and 2 are assessed on a collective basis. This means that they are grouped in pools of similar assets with similar credit risk characteristics including the type of product and the customer risk grade. Financial assets in Stage 3 are assessed on an individual basis or calculated collectively for those below a specified threshold.

Expected life

In considering the lifetime time frame for ECL in Stages 2 and 3, the standard generally requires use of the remaining contractual life adjusted, where appropriate, for prepayments, extension and other options. For certain revolving credit facilities which include both a drawn and undrawn component (e.g. credit cards and revolving lines of credit),

NOTES TO THE FINANCIAL STATEMENTS

Note 10.Provision for expected credit losses (Continued)

Westpac’s contractual ability to demand repayment and cancel the undrawn commitment does not limit the exposure to credit losses to the contractual notice period. For these facilities, lifetime is based on historical behaviour.

Movement between stages

Financial assets may move in both directions through the stages of the impairment model. Financial assets previously in Stage 2 may move back to Stage 1 if it is no longer considered that there has been a significant increase in credit risk. Similarly, financial assets in Stage 3 may move back to Stage 1 or Stage 2 if they are no longer assessed to be non-performing.

Critical accounting assumptions and estimates

Key judgements include when a significant increase in credit risk has occurred, the estimation of forward-looking macroeconomic information and overlays. Other factors which can impact the provision include the borrower’s financial situation, the realisable value of collateral, Westpac’s position relative to other claimants, the reliability of customer information and the likely cost and duration of recovering the loan.

Significant increase in credit risk (SICR)

Determining when a financial asset has experienced a SICR since origination is a critical accounting judgement which is based on the change in the probability of default (PD) since origination. In determining whether a change in PD represents a significant increase in risk, relative changes in PD and absolute PD thresholds are both considered based on the portfolio of the exposure.

Westpac does not rebut the presumption that instruments that are 30 days past due have experienced a SICR but this is used as a backstop rather than the primary indicator. In addition, providing a program-managed customer with a hardship arrangement or downgrading a transaction-managed exposure to a performing but weak credit risk grade of E (watchlist) or worse is generally treated as an indication of a SICR. Note 11.2 provides further details on the Group’s credit risk rating system.

Forward-looking macroeconomic information

The measurement of ECL for each stage and the assessment of significant increase in credit risk considers information about past events and current conditions as well as reasonable and supportable projections of future events and economic conditions. The estimation of forward-looking information is a critical accounting judgement. Westpac considers three future macroeconomic scenarios including a base case scenario along with upside and downside scenarios.

The macroeconomic variables used in these scenarios, based on current economic forecasts, include (but are not limited to) employment to population rates, real gross domestic product growth rates and residential and commercial property price indices.

●
Base case scenario

This scenario utilises the internal Westpac economics forecast used for strategic decision making and forecasting.

●
Upside scenario

This scenario represents a modest improvement on the base case scenario.

●
Downside scenario

The downside scenario is a more severe scenario with ECL higher than those under the base case scenario. This scenario assumes a recession with a combination of negative GDP growth, declines in commercial and residential property prices and an increase in the unemployment rate, which simultaneously impact ECL across all portfolios from the reporting date.

The three macroeconomic scenarios are probability weighted and together represent Westpac’s view of the forward looking distribution of potential loss outcomes. The weighting applied to each of the three macroeconomic scenarios takes into account historical frequency, current trends, and forward-looking conditions.

The macroeconomic variables and probability weightings of the three macroeconomic scenarios are subject to the approval of the Group Chief Financial Officer and Group Chief Risk Officer with oversight from the Board of Directors (and its Committees).

Overlays

Where appropriate, adjustments will be made to modelled outcomes to reflect reasonable and supportable information not already incorporated in the models.

Judgements can change with time as new information becomes available which could result in changes to the provision for ECL.

Note 10.Provision for expected credit losses (Continued)

Movement in provision for ECL on loans and credit commitments

The reconciliation of the provision for ECL tables for loans and credit commitments has been determined by an aggregation of monthly movements over the year. The key line items in the reconciliation represent the following:

●“Transfers between stages” represents transfers between Stage 1, Stage 2 and Stage 3 prior to remeasurement of the provision for ECL;
●“Business activity during the year” represents new accounts originated during the year net of those that were de-recognised due to final repayments during the year;
●“Net remeasurement of provision for ECL” represents the impact on the provision for ECL due to changes in credit quality during the year (including transfers between stages), changes in portfolio overlays, changes due to forward-looking economic scenarios and partial repayments and additional draw-downs on existing facilities over the year; and
●“Write-offs” represents a reduction in the provision for ECL as a result of derecognition of exposures where there is no reasonable expectation of full recovery.

Modelled provision for ECL on loans and credit commitments

The modelled provision for ECL on loans and credit commitments is a probability weighted estimate based on three scenarios which together represent the Group’s view of the forward-looking distribution of potential loss outcomes. Overlays are used to capture potential risk and uncertainty in the portfolio that are not captured in the underlying modelled ECL. Changes in the modelled provision for ECL and overlays are reflected through the “net remeasurement of provision for ECL” line item.

The downside scenario is a more severe scenario with expected credit losses higher than the base case. This scenario assumes a recession with a combination of negative GDP growth, declines in commercial and residential property prices and an increase in the unemployment rate, which simultaneously impact expected credit losses across all portfolios from the reporting date. The assumptions used in this scenario and relativities to the base case will be monitored having regard to the emerging economic conditions and updated where necessary. The upside scenario represents a modest improvement to the base case.

If 1% of Stage 1 loans and credit commitments (calculated on a 12 month ECL) were transferred to Stage 2 (calculated on a lifetime ECL), the provision for ECL on loans and credit commitments would increase by $113 million (2024: $93 million) for Westpac and $97 million (2024: $81 million) for the Parent Entity. If 1% of Stage 2 loans and credit commitments (calculated on a lifetime ECL) were transferred to Stage 1 (calculated on a 12 month ECL), the provision for ECL on loans and credit commitments would decrease by $20 million (2024: $21 million) for Westpac and $17 million (2024: $18 million) for the Parent Entity. These estimates apply the average modelled provision coverage ratio by stage to the transfer of loans and credit commitments.

The following table discloses the economic weights applied by Westpac and the Parent Entity. In 2025, the following changes were applied to scenario weights to reflect greater uncertainty from geopolitical developments, including in relation to international trade and tariff policies, global tensions and continuing global military conflicts:

●5.0% increase to downside; and
●2.5% decrease to both the upside and base scenarios.

The Group’s definition of default is aligned to the regulatory definition of default applied in the calculation of credit risk weighted assets.

Portfolio overlays

Portfolio overlays are used to address areas of risk, including significant uncertainties that are not captured in the underlying modelled ECL. Determination of portfolio overlays requires expert judgement and is thoroughly documented and subject to comprehensive internal governance and oversight. Overlays are continually reassessed and if the risk is judged to have changed (increased or decreased), or is subsequently captured in the modelled ECL, the overlay will be released or remeasured.

Westpac’s total portfolio overlays as at 30 September 2025 were $238 million (2024: $179 million) for the Group and $248 million (2024: $197 million) for the Parent Entity, and comprise:

●Climate-related risk: $71 million (2024: $70 million) for the Group and $71 million (2024: $70 million) for the Parent Entity for the expected impact of climate-related physical risk and transition risk to both retail and non-retail portfolios;
●Non-retail portfolios: $159 million (2024: $32 million) for the Group and $146 million (2024: $21 million) for the Parent Entity. Current period overlays primarily relate to portfolio seasoning in business lending and geographical areas experiencing higher stress not related to modelled outcomes; and
●Retail portfolios: $8 million (2024: $77 million) for the Group and $31 million (2024: $106 million) for the Parent Entity. Current period overlays relate to geographical areas experiencing higher stress and other risks not included in modelled outcomes.

Changes in portfolio overlays are reflected through the “net remeasurement of provision for ECL” line item.

Impact of changes in credit exposures on the provision for ECL on loans and credit commitments

●Stage 1 credit exposures increased by $90.4 billion (2024: net increase of $37.4 billion) for Westpac and $80.6 billion (2024: net increase of $35.7 billion) for the Parent Entity, driven by new lending across the housing and business loan portfolios. This volume growth, along with a deterioration in scenario weights and introduction of certain overlays, drove an increase in stage 1 ECL.
●Stage 2 credit exposures decreased by $35.7 billion (2024: increased by $0.1 billion) for Westpac and $27.1 billion (2024: increased by $1.6 billion) for the Parent Entity, driven by net runoff across housing and business portfolios

and net transfers to stage 1 in response to improved model economics, partly offset by a deterioration in scenario weights and reassessment of overlays. Overall, this drove a net decrease in stage 2 ECL.

●Stage 3 credit exposures decreased by $0.6 billion (2024: increased by $2.0 billion) for Westpac and $0.6 billion (2024: increased by $1.9 billion) for the Parent Entity. This was driven by a slowdown in new mortgage defaults and an increase in mortgages returning to performing, offset by certain downgrades in the business portfolio.

11.1.  Credit risk management framework

Please refer to Note 21.1 for details of Westpac’s overall risk management framework.

●Westpac maintains a Credit Risk Management Framework, Credit Risk Management Strategy, Credit Risk Appetite Statement, and a number of supporting policies that define roles and responsibilities, acceptable practices, limits and key controls.
●The Credit Risk Management Framework describes Westpac’s approach to managing Credit Risk and to deliver fair customer outcomes. It includes the following components: business strategy, risk identification, risk appetite, stress testing and scenario analysis, people and infrastructure, controls, monitoring and reporting, and governance.
●The BRiskC, Westpac Group Executive Risk Committee (RISKCO) and Westpac Group Credit Risk Committee (CREDCO) monitor the risk profile, performance and management of Westpac’s credit portfolio and the development and review of key credit risk policies.
●The Credit Risk Rating System Policy applies across the full credit risk ratings and risk estimates lifecycle (i.e. development, implementation, monitoring, validation, use, and independent review), helping us reliably assess the credit risk to which Westpac may be exposed. A senior management self-assessment is presented for discussion at BRiskC annually. An independent review is also completed annually.
●Model Risk independently assesses and approves all credit risk models, and periodically reviews these in line with the Group Model Risk Policy and governance. Models are approved under delegated authority from the Deputy Chief Risk Officer. Model Risk is overseen by Westpac’s Model Risk Committee.
●In determining the provision for ECL, the forward-looking economic inputs and the probability weightings of the forward-looking scenarios as well as any adjustments made to the modelled outcomes are subject to the approval of the Chief Financial Officer and the Chief Risk Officer with oversight from the Board of Directors (and its Committees).
●Policies are in place for the delegation of credit approval authorities and formal limits for the extension of credit.
●Credit policies are established and maintained throughout Westpac covering the end-to-end credit lifecycle including origination, evaluation, approval, documentation, settlement and ongoing management of credit risks. Specific policies and limits are in place to manage concentration risks, including to large exposures, industry concentration, and country risk.
●Climate change-related credit risks are considered in line with our Positions, Action Plans, and Sustainability Customer Requirements. Climate change risks are managed in accordance with the Sustainability Risk Management Framework (SRMF); Climate Risk Policy, Environmental, Social and Governance (ESG) Credit Risk Policy; and Board Risk Appetite Statements (RAS). The Climate Change Credit Risk Committee oversees work to identify and manage the potential impact on credit exposures from climate change-related transition and physical risks across Westpac and is a sub-committee of CREDCO.
●Westpac’s ESG Credit Risk Policy details Westpac’s overall approach to managing ESG risks in the credit risk process for applicable customers and transactions in Business & Wealth and Institutional.

11.2.  Credit risk ratings system

The principal objective of the credit risk rating system is to assess the credit risk to which Westpac is exposed. Westpac has two main approaches to this assessment.

Transaction-managed customers

Transaction managed customers are generally customers with business lending exposures. They are individually assigned a Customer Risk Grade (CRG), corresponding to their expected PD. Each facility is assigned an LGD. Westpac’s risk rating system has a tiered scale of risk grades for both non-defaulted customers and defaulted customers. Non-defaulted CRGs are mapped to Moody’s and S&P Global Ratings (S&P) external senior unsecured ratings.

The table below shows Westpac’s high level CRGs for transaction-managed portfolios mapped to Westpac’s credit quality disclosure categories and to their corresponding external rating.

Program-managed portfolio

The program-managed portfolio generally includes retail products such as mortgages, personal lending (including credit cards) as well as certain small to medium sized enterprise lending. These credit exposures are grouped into pools of similar risk based on the analysis of characteristics that have historically predicted the likelihood of default, and a PD is assigned relative to the credit exposure’s pool. The exposure is then assigned to strong, satisfactory or weak by benchmarking that PD against transaction-managed exposures, which are in turn mapped to external ratings per the above table. In addition, any program-managed exposures that are one or more days past due are classified as weak.

11.3.  Credit risk concentrations and maximum exposure to credit risk

Credit risk concentrations

Credit risk is concentrated when a number of counterparties are engaged in similar activities, have similar economic characteristics and thus may be similarly affected by changes in economic or other conditions.

Westpac monitors its credit portfolio to manage risk concentrations and rebalance the portfolio.

Individual customers or groups of related customers

Westpac has large exposure limits governing the aggregate size of credit exposure normally acceptable to individual customers and groups of related customers. These limits are tiered by customer risk grade.

Specific industries

Exposures to businesses, governments and other financial institutions are classified into a number of industry clusters based on related Australian and New Zealand Standard Industrial Classification (ANZSIC) codes and are monitored against Westpac’s industry risk appetite limits.

Individual countries

Westpac has limits governing risks related to individual countries, such as political situations, government policies and economic conditions that may adversely affect either a customer’s ability to meet its obligations to Westpac, or Westpac’s ability to realise its assets in a particular country.

Note 11.Credit risk management (Continued)

Maximum exposure to credit risk

The maximum exposure to credit risk (excluding collateral received) is represented by the carrying amount of on-balance sheet financial assets (which comprise cash and balances with central banks, collateral paid, trading securities and financial assets measured at FVIS, derivative financial instruments, investment securities, loans, other financial assets, and undrawn credit commitments.

The following tables set out the credit risk concentrations to which Westpac and the Parent Entity are exposed for on-balance sheet financial assets and for undrawn credit commitments.

The balances for trading securities and financial assets measured at FVIS and investment securities exclude equity securities as the primary financial risk is not credit risk.

The credit concentrations for each significant class of financial asset are:

​

NOTES TO THE FINANCIAL STATEMENTS

Note 11.Credit risk management (Continued)

11.5.  Credit risk mitigation, collateral and other credit enhancements

Westpac uses a variety of techniques to reduce the credit risk arising from its lending activities. This includes Westpac establishing that it has direct, irrevocable and unconditional recourse to collateral and other credit enhancements through obtaining legally enforceable documentation.

Collateral

The table below describes the nature of collateral or security held for each relevant class of financial asset.

​

​

Loans – housing and personala

    

Housing loans are secured by a mortgage over property and additional security may take the form of guarantees and deposits.

Personal lending (including credit cards and overdrafts) is predominantly unsecured. Where security is taken, it is restricted to eligible motor vehicles, caravans, campers, motor homes and boats. Personal lending also includes margin lending which is secured primarily by shares or managed funds.

Loans – business

​

Business loans may be secured, partially secured or unsecured. Security is typically taken by way of a mortgage over property and/or a general security agreement over business assets or other assets.

Other security such as guarantees, standby letters of credit or derivative protection may also be taken as collateral, if appropriate.

Trading securities, financial assets measured at FVIS and derivatives

​

These exposures are carried at fair value which reflects the credit risk.

For trading securities, no collateral is sought directly from the issuer or counterparty; however this may be implicit in the terms of the instrument (such as an asset-backed security). The terms of debt securities may include collateralisation.

For derivatives, master netting agreements are typically used to enable the effects of derivative assets and liabilities with the same counterparty to be offset when measuring these exposures. Additionally, collateralisation agreements are also typically entered into with major institutional counterparties to avoid the potential build-up of excessive mark-to-market positions. Derivative transactions are increasingly being cleared through central clearers.

​

a.

This includes collateral held in relation to associated credit commitments.

Management or risk mitigation

Westpac mitigates credit risk through controls covering:

Collateral and valuation management

    

The estimated realisable value of collateral held in support of loans is based on a combination of:

●
Formal valuations currently held for such collateral; and
●
Management’s assessment of the estimated realisable value of all collateral held.

This analysis also takes into consideration any other relevant knowledge available to management at the time. Updated valuations are obtained when appropriate.

Westpac revalues collateral related to financial markets positions on a daily basis and has formal processes in place to promptly call for collateral top-ups, if required. These processes include margining for non-centrally cleared customer derivatives as regulated by Australian Prudential Standard CPS226. The collateralisation arrangements are documented via the Credit Support Annex of the ISDA dealing agreements and Global Master Repurchase Agreements (GMRA) for repurchase transactions.

In relation to financial markets positions, Westpac only recognises collateral which is:

●
Cash, primarily in Australian dollars (AUD), New Zealand dollars (NZD), US dollars (USD), Canadian dollars (CAD), British pounds (GBP) or European Union euro (EUR);
●
Bonds issued by Australian Commonwealth, State and Territory governments or their Public Sector Enterprises, provided these attract a zero risk-weighting under Australian Prudential Standard (APS) 112;
●
Securities issued by other sovereign governments and supranationals as approved by an authorised credit officer; or
●
Protection bought via credit-linked notes (provided the proceeds are invested in cash or other eligible collateral).

Other credit enhancements

    

Westpac only recognises guarantees, standby letters of credit, or credit derivative protection from entities meeting minimum eligibility requirements (provided they are not related to the entity with which Westpac has a credit exposure) including but not limited to:

●
Sovereign;
●
Australia and New Zealand public sector;
●
ADIs and overseas banks with a minimum risk grade equivalent of A3 / A–; and
●
Others with a minimum risk grade equivalent of A3 / A–.

Credit Portfolio Management (CPM) manages Westpac’s corporate, sovereign and bank credit portfolios through monitoring the exposure and any offsetting hedge positions. CPM purchases credit protection from entities that meet minimum eligibility requirements.

Offsetting

​

Creditworthy customers domiciled in Australia and New Zealand may enter into formal agreements with Westpac, permitting Westpac to set-off gross credit and debit balances in their nominated accounts. Cross-border set-offs are not permitted.

Close-out netting is undertaken with counterparties with whom the Group has entered into a legally enforceable master netting agreement for their off-balance sheet financial market transactions in the event of default.

Further details of offsetting are provided in Note 23.

Central clearing

​

Westpac executes derivative transactions through central clearing counterparties. Central clearing counterparties mitigate risk through stringent membership requirements, the collection of margin against all trades placed, the default fund, and an explicitly defined order of priority of payments in the event of default.

NOTES TO THE FINANCIAL STATEMENTS

Deposits and other funding arrangements

Note 12.Deposits and other borrowings

Accounting policy

​

Deposits and other borrowings are initially recognised at fair value and subsequently either measured at amortised cost using the effective interest method or at fair value.

Deposits and other borrowings are designated at fair value if they are managed on a fair value basis, reduce or eliminate an accounting mismatch or contain an embedded derivative.

Where they are measured at fair value, any changes in fair value (except those due to changes in credit risk) are recognised in the income statement. The change in the fair value that is attributable to changes in credit risk is recognised in OCI except where it would create an accounting mismatch, in which case it is also recognised in the income statement.

Refer to Note 22 for balances measured at fair value and amortised cost.

Interest expense incurred is recognised in net interest income using the effective interest method.

Non-interest bearing relates to instruments which do not carry an entitlement to interest.

NOTES TO THE FINANCIAL STATEMENTS

Note 13.Debt issues

Accounting policy

​

Debt issues are bonds, notes, commercial paper and debentures that have been issued by entities in Westpac.

Debt issues are initially measured at fair value and subsequently either measured at amortised cost using the effective interest method or at fair value.

Debt issues are designated at fair value if they reduce or eliminate an accounting mismatch or contain an embedded derivative.

Where they are measured at fair value, any changes in fair value (except those due to changes in credit risk) are recognised in the income statement. The change in the fair value that is attributable to changes in credit risk is recognised in OCI except where it would create an accounting mismatch, in which case it is also recognised in the income statement.

Refer to Note 22 for balances measured at fair value and amortised cost.

Interest expense incurred is recognised within net interest income using the effective interest method.

​

In the following table, the distinction between short-term (12 months or less) and long-term (greater than 12 months) debt is based on the original maturity of the underlying security.

Note 14.Loan capital (Continued)

Common features of AT1 instruments issued by Westpac Banking Corporation

Payment conditions

Distributions and interest payments on the AT1 instruments are discretionary and will only be paid if the payment conditions are satisfied, including that the payment will not result in a breach of Westpac’s capital requirements under APRA’s prudential standards; not result in Westpac becoming, or being likely to become, insolvent; and if APRA does not object to the payment.

Broadly, if for any reason a distribution or interest payment has not been paid in full on the relevant payment date, Westpac must not determine or pay any dividends on Westpac ordinary shares or undertake a discretionary buyback or capital reduction of Westpac ordinary shares, unless the unpaid amount is paid in full within 20 business days of the relevant payment date or in certain other circumstances.

The AT1 instruments convert into Westpac ordinary shares in the following circumstances:

●Scheduled Conversion

On the scheduled conversion date, provided certain conversion conditions are satisfied, the relevant AT1 instrument1 will convert and holders will receive a variable number of Westpac ordinary shares calculated using the face value of the relevant AT1 instrument and the Westpac ordinary share price determined over the 20 business day period prior to the scheduled conversion date, including a 1% discount.

●Capital Trigger Event or Non-Viability Trigger Event

Westpac will be required to convert some or all AT1 instruments upon the occurrence of:

–

A capital trigger event, when Westpac determines, or APRA notifies Westpac in writing that it believes, Westpac’s Common Equity Tier 1 Capital ratio is equal to or less than 5.125% (on a Level 1 or Level 2 basis2); or

–

A non-viability trigger event, when APRA notifies Westpac in writing that it believes conversion, write-off or write-down of capital instruments of the Westpac, or public sector injection of capital (or equivalent support), in each case is necessary because without it, Westpac would become non-viable

For each AT1 instrument converted, holders will receive a variable number of Westpac ordinary shares calculated using the face value of the relevant AT1 instrument and the Westpac ordinary share price over the five business day period prior to the capital trigger event date or non-viability trigger event date and includes a 1% discount, subject to a maximum conversion number. The maximum conversion number is based on an ordinary share price broadly equivalent to 20% of the Westpac ordinary share price at the time of issue.

Following the occurrence of a capital trigger event or non-viability trigger event, if conversion does not occur within five business days, holders’ rights in relation to the relevant AT1 instrument will be immediately and irrevocably terminated.

●Conversion in other circumstances

Westpac is able to elect to convert1, or may be required to convert1, AT1 instruments early in certain circumstances. The terms of conversion are broadly similar to scheduled conversion, however, the maximum conversion number will depend on the conversion event.

●Early Redemption

Westpac is able to elect to redeem the relevant AT1 instrument on the optional redemption dates or for certain taxation or regulatory reasons, subject to APRA’s prior written approval.

Note 14.Loan capital (Continued)

Common features of subordinated notes

Issued by Westpac Banking Corporation

Interest payments are subject to Westpac being solvent at the time of, and immediately following, the interest payment.

Non-viability trigger event

The definition of non-viability trigger event is described under AT1 loan capital. Upon the occurrence of a non-viability trigger event, Westpac will be required to convert some or all subordinated notes into a variable number of Westpac ordinary shares calculated in a manner similar to that described under AT1 loan capital.

Following the occurrence of a non-viability trigger event, if conversion of a Tier 2 instrument does not occur within five business days, holders’ rights in relation to the relevant Tier 2 instrument will be immediately and irrevocably terminated.

Issued by Westpac New Zealand Limited

Interest payments are subject to Westpac New Zealand Limited being solvent at the time of, and immediately following, the interest payment.

Non-viability trigger event

Tier 2 instruments issued by Westpac New Zealand Limited do not have a non-viability trigger event. These instruments qualify as Tier 2 capital under the RBNZ capital adequacy framework but not under APRA’s capital adequacy framework.

​

Note 15.Securitisation, covered bonds and other transferred assets

Westpac enters into transactions in the normal course of business by which financial assets are transferred to counterparties or structured entities. Depending on the circumstances, these transfers may result in derecognition of the assets in their entirety, partial derecognition or no derecognition of the assets subject to the transfer. For Westpac’s accounting policy on derecognition of financial assets refer to the Financial Assets and Financial Liabilities.

Securitisation

Securitisation is the transferring of assets (or an interest in either the assets or the cash flows arising from the assets) to a structured entity which then issues the majority of interest bearing debt securities to third party investors for funding deals and to Westpac for liquidity deals. The Group transfers residential mortgages to these structured entities, however the Group retains the risks and rewards of the residential mortgages and continues to recognise the mortgages as financial assets.

Securitisation of its own assets is used by Westpac as a funding and liquidity tool. For securitisation structured entities which Westpac controls, as defined in Note 30, the structured entities are classified as subsidiaries and consolidated. When assessing whether Westpac controls a structured entity, it considers its exposure to and ability to affect variable returns. Westpac may have variable returns from a structured entity through ongoing exposures to the risks and rewards associated with the assets, the provision of derivatives, liquidity facilities, trust management and operational services.

Undrawn funding and liquidity facilities of $251 million (2024: $345 million) were provided by Westpac for the securitisation of its own assets.

Covered bonds

Westpac has two covered bond programs relating to Australian residential mortgages (Australian Program) and New Zealand residential mortgages (New Zealand Program). Under these programs, selected pools of residential mortgages are assigned to bankruptcy remote structured entities which provide guarantees on the payments to bondholders. The Group retains the majority of the risks and rewards of the residential mortgages and continues to recognise the mortgages as financial assets. Through the guarantees and derivatives with the structured entities, Westpac has variable returns from these structured entities and consolidates them.

Repurchase agreements

Where securities are sold subject to an agreement to repurchase at a predetermined price, they remain recognised in the balance sheet in their original category (i.e. Trading securities or Investment securities).

The cash consideration received is recognised as a liability (Repurchase agreements). Refer to Note 19 for further details.

a.The carrying amount of assets securitised exceeds the amount of notes issued primarily because the carrying amount includes both principal and income received from the transferred assets.
b.The difference between the carrying values of covered bonds and the assets pledged reflects the over-collateralisation required to maintain the ratings of the covered bonds and also additional assets to allow immediate issuance of additional covered bonds if required. These additional assets can be repurchased by Westpac at its discretion, subject to the conditions set out in the transaction documents.

Trading securities and financial assets measured at fair value through income statement (FVIS)

Accounting policy

​

Trading securities

Trading securities include portfolios of actively traded debt and equity instruments, pledged instruments and instruments acquired for sale in the near term, including those backed by government and semi-government securities. The instruments are measured at fair value.

As part of its trading activities, Westpac also lends and borrows securities on a collateralised basis. Securities lent remain on Westpac’s balance sheet and securities borrowed are not reflected on Westpac’s balance sheet, as the risks and rewards of ownership remain with the initial holder. Where cash is provided as collateral, the amount advanced to or received from third parties is recognised as a receivable in collateral paid or as a borrowing in collateral received respectively.

Reverse repurchase agreements

Securities purchased under these agreements are not recognised in the balance sheet, as Westpac has not obtained the risks and rewards of ownership. The cash consideration paid is recognised as a reverse repurchase agreement, which forms part of a portfolio that is measured at fair value.

Other financial assets measured at FVIS

Other financial assets measured at FVIS include:

●
Non-trading portfolio securities measured at fair value where this eliminates or significantly reduces an accounting mismatch, or they are part of a group of instruments that are managed on a fair value basis;
●
Non-trading debt securities that do not have contractual cash flows that represent SPPI on the principal balance outstanding; or
●
Non-trading equity securities for which we have not made irrevocable designation to be measured at FVOCI.

Fair value gains and losses on these financial assets are recognised in the income statement. Interest earned from debt securities is recognised in interest income (Note 3) while dividends on equity securities are recognised in non-interest income (Note 4).

NOTES TO THE FINANCIAL STATEMENTS

Note 17.Investment securities

Accounting policy

​

Investment securities include debt securities and equity securities. It includes debt and equity securities that are measured at FVOCI and debt securities measured at amortised cost. These instruments are classified based on the criteria disclosed under the heading “Financial assets and financial liabilities” prior to Note 9.

Debt securities measured at FVOCI

Includes debt instruments that have contractual cash flows which represent SPPI on the principal balance outstanding and are held within a business model whose objective is achieved both through collecting these cash flows or selling the financial asset.

These securities are measured at fair value with unrealised gains and losses recognised in OCI except for interest income, impairment charges, FX gains and losses and fair value hedge adjustments which are recognised in the income statement.

Impairment is measured using the same ECL model applied to financial assets measured at amortised cost. Impairment is recognised in the income statement with a corresponding amount in OCI with no reduction of the carrying value of the debt security which remains at fair value. Refer to Note 6 and Note 10 for further details.

The cumulative gain or loss recognised in OCI is subsequently recognised in the income statement when the instrument is disposed.

Debt securities measured at amortised cost

Includes debt instruments that have contractual cash flows which represent SPPI on the principal balance outstanding and are held within a business model whose objective is achieved through holding the financial asset to collect these cash flows.

These securities are initially recognised at fair value plus directly attributable transaction costs. They are subsequently measured at amortised cost using the effective interest method and are presented net of any provision for ECL, determined using the ECL model.

Equity securities

Equity securities are measured at FVOCI where they are not held for trading, Westpac does not have control or significant influence over the investee and where an irrevocable election is made to measure them at FVOCI.

These securities are measured at fair value with unrealised gains and losses recognised in OCI except for dividend income which is recognised in the income statement. The cumulative gain or loss recognised in OCI is not subsequently recognised in the income statement when the instrument is disposed.

NOTES TO THE FINANCIAL STATEMENTS

Note 19.Other financial liabilities

Accounting policy

​

Other financial liabilities include liabilities measured at amortised cost as well as liabilities which are measured at FVIS. Financial liabilities measured at FVIS include:

●
Trading liabilities (i.e. securities sold short); and
●
Liabilities designated at FVIS (i.e. certain repurchase agreements).

Refer to Note 22 for balances measured at fair value and amortised cost.

Repurchase agreements

Where securities are sold subject to an agreement to repurchase at a predetermined price, they remain recognised in the balance sheet in their original category (i.e. ‘Trading securities’ or ‘Investment securities’).

The cash consideration received is recognised as a liability (‘Repurchase agreements’). Repurchase agreements are designated at fair value where this eliminates or significantly reduces an accounting mismatch, or they are part of a group of instruments that are managed on a fair value basis. Otherwise they are measured on an amortised cost basis.

Where a repurchase agreement is designated at fair value, any changes in fair value (except those due to changes in credit risk) are recognised in the income statement as they arise. The change in fair value that is attributable to credit risk is recognised in OCI except where it would create an accounting mismatch, in which case it is also recognised in the income statement.

Note 20.Derivative financial instruments

Accounting policy

​

Derivative financial instruments are instruments whose values are derived from the value of an underlying asset, reference rate or index and include forwards, futures, swaps and options.

Westpac uses derivative financial instruments for meeting customers’ needs, our Asset and Liability Management (ALM) activities, and undertaking market making and positioning activities.

Trading derivatives

Derivatives which are used in our ALM activities but are not designated into a hedge accounting relationship are considered economic hedges. These derivatives, along with derivatives used for meeting customers’ needs and undertaking market making and positioning activities, are measured at FVIS and are disclosed as trading derivatives.

Hedging derivatives

Hedging derivatives are those which are used in our ALM activities and have also been designated into one of three hedge accounting relationships: fair value hedge; cash flow hedge; or hedge of a net investment in a foreign operation. These derivatives are measured at fair value. These hedge designations and the associated accounting treatment are detailed below.

For more details regarding Westpac’s ALM activities, refer to Note 21.

Fair value hedges

Fair value hedges are used to hedge the exposure to changes in the fair value of an asset or liability.

Changes in the fair value of derivatives and the hedged asset or liability in fair value hedges are recognised in interest income. The carrying value of the hedged asset or liability is adjusted for the changes in fair value related to the hedged risk.

If a hedge is discontinued, any fair value adjustments to the carrying value of the asset or liability are amortised to net interest income over the period to maturity. If the asset or liability is sold, any unamortised adjustment is immediately recognised in net interest income.

Cash flow hedges

Cash flow hedges are used to hedge the exposure to variability of cash flows attributable to an asset, liability or future forecast transaction.

For effective hedges, changes in the fair value of derivatives are recognised in the cash flow hedge reserve through OCI and subsequently recognised in interest income when the cash flows attributable to the asset or liability that was hedged impact the income statement.

For hedges with some ineffectiveness, the changes in the fair value of the derivatives relating to the ineffective portion are immediately recognised in interest income.

If a hedge is discontinued, any cumulative gain or loss remains in OCI. It is amortised to net interest income over the period in which the asset or liability that was hedged also impacts the income statement.

If a hedge of a forecast transaction is no longer expected to occur, any cumulative gain or loss in OCI is immediately recognised in net interest income.

Net investment hedges

Net investment hedges are used to hedge FX risks arising from a net investment of a foreign operation.

For effective hedges, changes in the fair value of derivatives are recognised in the foreign currency translation reserve through OCI.

For hedges with some ineffectiveness, the changes in the fair value of the derivatives relating to the ineffective portion are immediately recognised in non-interest income.

If a foreign operation is disposed of, any cumulative gain or loss in OCI is immediately recognised in non-interest income.

NOTES TO THE FINANCIAL STATEMENTS

Note 20.Derivative financial instruments (Continued)

Hedge accounting

Westpac designates derivatives into hedge accounting relationships in order to manage the volatility in earnings and capital that would otherwise arise from interest rate and FX risks that may result from differences in the accounting treatment of derivatives and underlying exposures. These hedge accounting relationships and the risks they are used to hedge are described below.

Westpac enters into one-to-one hedge relationships to manage specific exposures where the terms of the hedged item significantly match the terms of the hedging instrument. Westpac also uses dynamic hedge accounting where the hedged items are part of a portfolio of assets and/or liabilities that frequently change. In this hedging strategy, the exposure being hedged and the hedging instruments may change frequently rather than there being a one-to-one hedge accounting relationship for a specific exposure.

Fair value hedges

Interest rate risk

Westpac hedges its interest rate risk to reduce exposure to changes in fair value due to interest rate fluctuations over the hedging period. Interest rate risk arising from fixed rate debt issuances and fixed rate bonds classified as investment securities at FVOCI is hedged with single currency fixed to floating interest rate derivatives. Westpac also hedges its benchmark interest rate risk from fixed rate foreign currency denominated debt issuances using interest rate swaps and cross currency swaps. In applying fair value hedge accounting, Westpac primarily uses one-to-one hedge accounting to manage specific exposures.

Westpac also uses a dynamic hedge accounting strategy for fair value portfolio hedge accounting of some fixed rate mortgages to reduce exposure to changes in fair value due to interest rate fluctuations over the hedging period. These fixed rate mortgages are allocated to time buckets based on their expected repricing dates and the fixed-to-floating interest rate derivatives are designated accordingly to the capacity in the relevant time buckets.

Westpac hedges the benchmark interest rate which generally represents the most significant component of the changes in fair value. The benchmark interest rate is a component of interest rate risk that is observable in the relevant financial markets, for example, BBSW and AONIA for AUD interest rates, SOFR for USD interest rates and BKBM for NZD interest rates. Ineffectiveness may arise from timing or discounting differences on repricing between the hedged item and the derivative. For the portfolio hedge accounting ineffectiveness also arises from prepayment risk (i.e. the difference between actual and expected prepayment of loans). In order to manage the ineffectiveness from early repayments and accommodate new originations the portfolio hedges are de-designated and re-designated periodically.

Cash flow hedges

Interest rate risk

Westpac’s exposure to the volatility of interest cash flows from customer deposits and loans is hedged with interest rate derivatives using a dynamic hedge accounting strategy called macro cash flow hedges. Customer deposits and loans are allocated to time buckets based on their expected repricing dates. The interest rate derivatives are designated accordingly to the gross asset or gross liability positions for the relevant time buckets. Westpac hedges the benchmark interest rate which generally represents the most significant component of the changes in fair value. The benchmark interest rate is a component of interest rate risk that is observable in the relevant financial markets, for example, BBSW and AONIA for AUD interest rates, SOFR for USD interest rates and BKBM for NZD interest rates. Ineffectiveness may arise from timing or discounting differences on repricing between the hedged item and the interest rate derivative. Ineffectiveness also arises if the notional values of the interest rate derivatives exceed the capacity for the relevant time buckets. The hedge accounting relationship is reviewed on a monthly basis and the hedging relationships are de-designated and re-designated if necessary.

FX risk

Westpac’s exposure to foreign currency principal and credit margin cash flows from fixed and floating rate foreign currency debt issuances is hedged through the use of cross currency and foreign exchange derivative contracts in a one-to-one hedging relationship to manage the changes between the foreign currency and AUD. In addition, for floating rate foreign currency debt issuances, Westpac hedges from foreign floating to primarily AUD or NZD floating interest rates. These exposures represent the most significant components of fair value. Ineffectiveness may arise from timing or discounting differences on repricing between the hedged item and the cross currency derivative.

Note 20.Derivative financial instruments (Continued)

Net investment hedges

FX risk

Structural FX risk results from Westpac’s capital deployed in offshore branches and subsidiaries, where it is denominated in currencies other than Australian dollars. As exchange rates move, the Australian dollar equivalent of offshore capital is subject to change that could introduce significant variability to Westpac’s reported financial results and capital ratios.

Westpac uses FX forward contracts when hedging the currency translation risk arising from net investments in foreign operations. Westpac currently applies hedge accounting, predominantly to its net investment in New Zealand operations which is the most material offshore operation and therefore the hedged risk is the movement of the NZD against the AUD. Ineffectiveness only arises if the notional values of the FX forward contracts exceed the net investment.

Economic hedges

As part of Westpac’s ALM activities, economic hedges may be entered into to hedge New Zealand future earnings and long-term funding transactions for risk management purposes. These hedges do not qualify for hedge accounting and therefore are not included in the hedging instrument disclosures below.

Hedging instruments

The following tables show the carrying value of hedging instruments and a maturity analysis of the notional amounts of the hedging instruments in one-to-one hedge relationships categorised by the types of hedge relationships and the hedged risk.

The carrying amount of investment securities at fair value through other comprehensive income does not include a fair value hedge adjustment as the hedged asset is measured at fair value. The fair value hedge accounting adjustment results in a transfer from other comprehensive income to the income statement.

There were nil FVHA gains/losses (2024: Nil) included in the above carrying amounts relating to hedged items that have ceased to be adjusted for hedging gains and losses.

The pre-tax impact of cash flow and net investment hedges on cash flow hedge reserves is detailed below:

There were nil net gains/losses (2024: net gains $16 million) remaining in the cash flow hedge reserve relating to hedge relationships for which hedge accounting is no longer applied for Westpac and the Parent Entity.

As disclosed in Note 26, the net gains from changes in the fair value of net investment hedges were $95 million (2024: net gain $28 million) for Westpac and $53 million (2024: net gain $31 million) for the Parent Entity. Included in the foreign currency translation reserve is a loss of $158 million (2024: $158 million loss) for Westpac and $162 million (2024: $162 million loss) for the Parent Entity relating to discontinued hedges of our net investment in USD operations. This would only be transferred to the income statement on disposal of the related USD operations.

NOTES TO THE FINANCIAL STATEMENTS

Note 20.Derivative financial instruments (Continued)

Hedge effectiveness

Hedge effectiveness is tested prospectively at inception and during the lifetime of hedge relationships. For one-to-one hedge relationships this testing uses a qualitative assessment of matched terms where the critical terms of the derivatives used as the hedging instrument match the terms of the hedged item. In addition, a quantitative effectiveness test is performed for all hedges which could include regression analysis, dollar offset and/or sensitivity analysis.

Retrospective testing is also performed to determine whether the hedge relationship remains highly effective so that hedge accounting can continue to be applied and also to determine any ineffectiveness. These tests are performed using regression analysis and the dollar offset method.

The following tables provide information regarding the determination of hedge effectiveness:

NOTES TO THE FINANCIAL STATEMENTS

Note 21.Risk management, funding and liquidity risk and market risk (Continued)

For each of its material risks, Westpac maintains risk management frameworks and a number of supporting policies that define roles and responsibilities, acceptable practices, limits and key controls:

Risk

Risk management framework and controls

Funding and
liquidity risk

●

Funding and liquidity risk is measured and managed in accordance with the policies and processes defined in the Board-approved Liquidity Risk Management Framework which is part of the Westpac Board-approved Risk Management Strategy.

●

Responsibility for managing Westpac’s liquidity and funding positions in accordance with the Liquidity Risk Management Framework is delegated to Treasury, under the oversight of Group ALCO and Treasury Risk.

●

Westpac’s Liquidity Risk Management Framework sets out Westpac’s funding and liquidity risk appetite, roles and responsibilities of key people managing funding and liquidity risk within Westpac, risk reporting and control processes and limits and targets used to manage Westpac’s balance sheet.

●

Treasury undertakes an annual funding review that outlines Westpac’s balance sheet funding strategy over a five year period. This review encompasses trends in global markets, peer analysis, wholesale funding capacity, expected funding requirements and a funding risk analysis. This strategy is continuously reviewed to take account of changing market conditions, investor sentiment and estimations of asset and liability growth rates.

●

Westpac monitors the composition and stability of its funding so that it remains within Westpac’s funding risk appetite. This includes compliance with both the Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR).

●

Westpac holds a portfolio of liquid assets for several purposes, including as a buffer against unforeseen funding requirements. The level of liquid assets held takes into account the liquidity requirements of Westpac’s balance sheet under normal and stress conditions.

●

Treasury maintains a contingent funding plan that outlines the steps that should be taken by Westpac in the event of an emerging ‘funding crisis’. The plan is aligned with Westpac’s broader Liquidity Crisis Management Policy which is approved annually by the Board.

●

Daily liquidity risk reports are reviewed by Westpac’s Treasury and Treasury Risk teams. Liquidity reports are presented to Group ALCO monthly and to the Board quarterly.

Market risk

​

●

The Market Risk Framework describes Westpac’s approach to managing traded and non- traded market risk.

●

Traded market risk includes interest rate, FX, commodity, equity price, credit spread and volatility risks. Non-traded market risk includes interest rate and credit spread risks.

●

Market risk is managed using VaR and Stressed VaR (SVaR) limits, Net interest income at risk (NaR) and structural risk limits (including credit spread and interest rate basis point value limits) as well as scenario analysis and stress testing.

●

The BRiskC approves the risk appetite for traded and non-traded risks through the use of VaR, SVaR, NaR and specific structural risk limits. This includes separate VaR sub-limits for the trading activities of Financial Markets and Treasury and for non-traded ALM activities.

●

Market risk limits are assigned to business management based upon the Bank’s risk appetite and business strategies in addition to the consideration of market liquidity and concentration.

●

Market risk positions are managed by the trading desks and ALM unit consistent with their delegated authorities and the nature and scale of the market risks involved.

●

Daily monitoring of current exposure and limit utilisation is conducted independently by Market Risk teams, which monitor market risk exposures against VaR and structural risk limits. Daily VaR position reports are produced by risk type, by product lines and by geographic region. Quarterly reports are produced for the Westpac Group Market Risk Committee (MARCO), RISKCO and the BRiskC.

●

Daily stress testing and back testing of VaR results are performed to support model integrity and to analyse extreme or unexpected movements, and the Head of Market, Capital & Liquidity Risk has ratified an approved stress escalation framework.

●

The BRiskC has approved a framework for profit or loss escalation which considers both single day and 20 day cumulative results.

●

Treasury’s ALM unit is responsible for managing the non-traded interest rate risk including risk mitigation through hedging using derivatives. This is overseen by the Market Risk unit and reviewed by Treasury Financial Risk Committee (TRFC), MARCO, RISKCO and BRiskC. The Group ALCO provides additional oversight of non-traded market risk and alignment with Group strategy in reviewing NaR and the durations of capital and non-rate sensitive deposit hedges.

Note 21.Risk management, funding and liquidity risk and market risk (Continued)

21.2.  Funding and liquidity risk

21.2.1. Liquidity modelling

In managing liquidity for Westpac, Treasury utilises balance sheet forecasts and the maturity profile of Westpac’s wholesale funding portfolio to project liquidity outcomes. Local liquidity limits are also used by Westpac in applicable jurisdictions to ensure liquidity is managed efficiently and prudently.

In addition, Westpac conducts regular stress testing to assess its ability to meet cash flow obligations under a range of market conditions and scenarios. These scenarios inform liquidity limits and strategic planning.

21.2.2. Sources of funding

Sources of funding are regularly reviewed to maintain a wide diversification by currency, geography, product and term. Sources include, but are not limited to:

●Deposits;
●Debt issues;
●Proceeds from sale of marketable securities;
●Repurchase agreements with central banks;
●Principal repayments on loans;
●Interest income; and
●Fee income.

Liquid assets

Treasury holds a portfolio of high-quality liquid assets as a buffer against unforeseen funding requirements. These assets are held in cash, or are otherwise eligible for repurchase agreements with the Reserve Bank of Australia or another central bank and include Government, State Government and highly rated investment grade securities. The level of liquid asset holdings is reviewed frequently and is consistent with both the requirements of the balance sheet and market conditions.

A summary of Westpac’s liquid asset holdings is as follows:

Movements in Westpac’s funding composition in 2025 included:

●Customer deposits increased by $49.4 billion and now account for 68.1% of Westpac’s total funding (including equity) at 30 September 2025, up from 66.9% at 30 September 2024;
●Long-term funding with a residual maturity greater than 12 months accounted for 12.9% of Westpac’s total funding at 30 September 2025. Funding from securitisation accounted for a further 0.5% of total funding. Westpac raised $28.1 billion of long-term wholesale funding in 2025, supported by constructive conditions in global capital markets. This was lower than prior financial years reflecting strong growth in customer deposits and lower wholesale funding maturities to be refinanced;
●Wholesale funding with a residual maturity less than 12 months accounted for 11.6% of Westpac’s total funding at 30 September 2025, up from 11.4% at 30 September 2024. This portfolio, including long-term funding with a residual maturity less than one year, had a weighted average maturity of 153 days; and
●Funding from equity increased by $1.0 billion in 2025 and made up 6.9% of total funding at 30 September 2025, down from 7.2% at 30 September 2024, reflecting the impact of the on-market share buyback.

Borrowings and outstanding issuances from existing debt programs at 30 September 2025 can be found in Note 12, Note 13, Note 14 and Note 19.

Funding for Lending Programme (FLP)

On 11 November 2020, the Reserve Bank of New Zealand (RBNZ) announced a stimulus through the FLP commencing in December 2020. The FLP provided funding to New Zealand banks at the prevailing OCR for a term of three years secured by high quality collateral. The size of the funding available under the FLP included an initial allocation of 4% of each bank’s eligible loans. A conditional additional allocation of up to 2% of eligible loans was also available, subject to growth in eligible loans, for a total size of up to 6% of eligible loans. The programme started on 7 December 2020 and ran until 6 December 2022. During the year, Westpac New Zealand Limited has made scheduled repayments on the programme and as at 30 September 2025 the amount outstanding totalled NZ$1,110 million (30 September 2024: NZ$2,981 million).

21.2.4. Contractual maturity of financial liabilities

The following tables present cash flows associated with financial liabilities, payable at the balance sheet date, by remaining contractual maturity. The amounts disclosed in the table are the future contractual undiscounted cash flows, whereas Westpac manages inherent liquidity risk based on expected cash flows.

Cash flows associated with financial liabilities include both principal payments as well as fixed or variable interest payments incorporated into the relevant coupon period. Principal payments reflect the earliest contractual maturity date. Derivative liabilities designated in hedge accounting relationships and used as economic hedges are expected to be held for their remaining contractual lives, and reflect gross cash flows over the remaining contractual term.

Derivatives held for trading (excluding economic hedges) and certain liabilities classified in “Other financial liabilities” which are measured at FVIS are not managed for liquidity purposes on the basis of their contractual maturity, and accordingly these liabilities are presented in the up to 1 month column. Only the liabilities that Westpac manages based on their contractual maturity are presented on a contractual undiscounted basis in the following tables.

​

NOTES TO THE FINANCIAL STATEMENTS

Note 21.Risk management, funding and liquidity risk and market risk (Continued)

21.2.5. Expected maturity

The financial liability balances in the following tables will not agree to the contractual maturity tables (Note 21.2.4) due to the impact of discounting and the exclusion of interest accruals beyond the reporting period. Assets and liabilities that have no specific maturity (such as equity securities) are generally included in the ‘Greater than 12 months’ column. Loans and deposits are presented in the following table on a contractual basis, however the behavioural life may differ. Loans may be repaid earlier than their contractual maturity and Westpac would expect a large proportion of deposit balances to be retained.

21.3.  Market risk

21.3.1. Value-at-Risk

Westpac uses VaR as one of the mechanisms for controlling both traded and non-traded market risk.

VaR is a statistical estimate of the potential loss in earnings over a specified period of time and to a given level of confidence based on historical market movements. The confidence level indicates the probability that the loss will not exceed the VaR estimate on any given day.

VaR seeks to take account of all material market variables that may cause a change in the value of the portfolio, including interest rates, FX rates, price changes, volatility and the correlations between these variables. Daily monitoring of current exposures and VaR and structural concentration limit utilisation is conducted independently by the Market Risk unit. These limits are supplemented by escalation triggers for material profit or loss, and stress testing of risks beyond the 99% confidence interval.

21.3.3. Non-traded market risk

Non-traded market risk includes Interest Rate Risk in the Banking Book (IRRBB) – the risk to net interest income or the economic value on banking book items as a result of interest rate changes.

Net interest income (NII) sensitivity is monitored using the Net interest income-at-Risk (NaR) model. The NaR model combines the underlying balance sheet data with assumptions about runoffs, new business, and expected repricing behaviour. This simulates a series of potential NII outcomes, over a one year time horizon subject to 100 basis point shift up and down from the current market interest rates in Australia and New Zealand.

Net interest income-at-Risk

The following table depicts potential NII outcomes assuming a worst case outcome between a 100 basis point rate shock up or down with a 12 month time horizon (expressed as a percentage of reported NII):

As at 30 September 2025 the Value at Risk – IRRBB for the Parent Entity was $104 million (2024: $77 million).

Risk mitigation

IRRBB stems from the ordinary course of banking activities, including structural interest rate risk (the mismatch between the duration of assets and liabilities) and capital management.

Westpac hedges its exposure to such interest rate risk using derivatives. Further details on Westpac’s hedge accounting are discussed in Note 20.

The same controls used to monitor traded market risk allow management to monitor and manage IRRBB.

Structural FX risk

Structural FX risk results from the generation of foreign currency denominated earnings and from Westpac’s capital deployed in offshore branches and subsidiaries, where it is denominated in currencies other than Australian dollars. As exchange rates move, the Australian dollar equivalent of offshore earnings and capital is subject to change that could introduce significant variability to the Bank’s reported financial results and capital ratios.

Note 20 includes details on the net investment hedges related to structural FX risk and economic hedges of New Zealand future earnings.

1.Based on a 1 day holding period and 1 year of historical data to allow comparison to the traded market risk results, noting IRRBB is managed to a longer holding period.

Note 22.Fair values of financial assets and financial liabilities

Accounting policy

​

The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

On initial recognition, the transaction price generally represents the fair value of the financial instrument unless there is observable information from an active market to the contrary. Where unobservable information is used, the difference between the transaction price and the fair value (day one profit or loss) is recognised in the income statement over the life of the instrument or when the inputs become observable.

Critical accounting assumptions and estimates

The majority of valuation models used by Westpac employ only observable market data as inputs. However, for certain financial instruments data may be employed which is not readily observable in current markets.

The availability of observable inputs is influenced by factors such as:

●

Product type;

●

Depth of market activity;

●

Maturity of market models; and

●

Complexity of the transaction.

Where unobservable market data is used, more judgement is required to determine fair value. The significance of these judgements depends on the significance of the unobservable input to the overall valuation. Unobservable inputs are generally derived from other relevant market data and adjusted against:

●

Standard industry practice;

●

Economic models; and

●

Observed transaction prices.

In order to determine a reliable fair value for a financial instrument, management may apply adjustments to the techniques previously described. These adjustments reflect Westpac’s assessment of factors that market participants would consider in setting the fair value.

These adjustments incorporate bid/offer spreads, credit valuation adjustments (CVA) and funding valuation adjustments (FVA).

​

Fair Valuation Control Framework

Westpac uses a Fair Valuation Control Framework where the fair value is either determined or validated by a function independent of the transaction. This framework formalises the policies and procedures used to achieve compliance with relevant accounting, industry and regulatory standards. The framework includes specific controls relating to:

●The revaluation of financial instruments;
●Independent price verification;
●Fair value adjustments; and
●Financial reporting.

A key element of the framework is the Revaluation Committee, comprising senior valuation specialists from within Westpac. The Revaluation Committee reviews the application of the agreed policies and procedures to assess that a fair value measurement basis has been applied.

The method of determining fair value differs depending on the information available.

Fair value hierarchy

A financial instrument’s categorisation within the valuation hierarchy is based on the lowest level input that is significant to the fair value measurement.

Westpac categorises all fair value instruments according to the hierarchy described below.

Valuation techniques

Westpac applies market accepted valuation techniques in determining the fair valuation of over the counter (OTC) derivatives. This includes CVA and FVA, which incorporate credit risk and funding costs and benefits that arise primarily in relation to uncollateralised derivative positions, respectively.

The specific valuation techniques, the observability of the inputs used in valuation models and the subsequent classification for each significant product category are outlined as follows:

a.

The contractual outstanding amount payable at maturity was $47,838 million (2024: $47,328 million) for the Group and $46,239 million (2024: $45,603 million) for the Parent Entity.

b.

The contractual outstanding amount payable at maturity for the Group is $20,032 million (2024: $19,320 million) and $19,548 million for the Parent Entity (2024: $19,320 million).

c.

The contractual outstanding payable at maturity was $4,877 million (2024: $5,678 million) for the Group and $2,446 million (2024: $2,226 million) for the Parent Entity. The cumulative change in the fair value of debt issues attributable to changes in Westpac’s own credit risk was $37 million decrease (2024: $58 million decrease) for the Group and Parent Entity.

​

$48,184 million of assets and $274 million of liabilities for the Group and Parent Entity have been transferred from Level 2 to Level 1 in 2025. This followed a detailed review of the levelling of certain US Treasury securities and certain Australian semi-government bonds using additional granular data sourced from independent pricing services, which confirmed that observable prices in an active market are available for the securities transferred. Transfers in and transfers out are reported using the end of period fair values.

Transfers into and out of Level 3 have occurred due to changes in observability in the significant inputs into the valuation models used to determine the fair value of the related financial instruments. Transfers in and transfers out are reported using the end of period fair values.

Significant unobservable inputs

Sensitivities to reasonably possible changes in non-market observable valuation assumptions would not have a material impact on Westpac’s reported results.

Day one profit or loss

The closing balance of unrecognised day one profit for both Westpac and the Parent Entity as at 30 September 2025 was $2 million (2024: $1 million).

Financial instruments not measured at fair value

For financial instruments not measured at fair value on a recurring basis, fair value has been derived as follows:

Instrument

    

Valuation

Loans

​

Where available, the fair value of loans is based on observable market transactions, otherwise fair value is estimated using discounted cash flow models. For variable rate loans, the discount rate used is the current effective interest rate. The discount rate applied for fixed rate loans reflects the market rate for the maturity of the loan and the credit worthiness of the borrower.

Investment securities

​

The carrying value approximates the fair value. The balance principally relates to government securities from illiquid markets. Fair value is monitored by reference to recent issuances.

Deposits and other borrowings

​

Fair values of deposit liabilities payable on demand (non-interest bearing, interest bearing and savings deposits) approximate their carrying value. Fair values for term deposits are estimated using discounted cash flows, applying market rates offered for deposits of similar remaining maturities.

Debt issues and loan capital

​

Fair values are calculated using a discounted cash flow model. The discount rates applied reflect the terms of the instruments, the timing of the estimated cash flows and are adjusted for any changes in Westpac’s credit spreads.

All other financial assets and liabilities

​

For all other financial assets and liabilities, the carrying value approximates the fair value. These items are either short-term in nature, re-price frequently or are of a high credit rating.

Note 23.Offsetting financial assets and financial liabilities

Accounting policy

​

Financial assets and liabilities are presented net in the balance sheet when Westpac has a legally enforceable right to offset them in all circumstances and there is an intention to settle the asset and liability on a net basis, or to realise the asset and settle the liability simultaneously. The gross assets and liabilities behind the net amounts reported in the balance sheet are disclosed in the following tables.

​

Some of Westpac’s offsetting arrangements are not enforceable in all circumstances. The amounts in the tables below may not tie back to the balance sheet if there are balances which are not subject to offsetting or enforceable netting arrangements. The amounts presented in this note do not represent the credit risk exposure of Westpac or Parent Entity. Refer to Note 11 for information on credit risk management. The offsetting and collateral arrangements and other credit risk mitigation strategies used by Westpac are further explained in the ‘Management of risk mitigation’ section of Note 11.5.

g.

Repurchase agreements form part of other financial liabilities in Note 19.

Other recognised financial instruments

These financial assets and liabilities are subject to master netting agreements which are not enforceable in all circumstances, so they are recognised gross in the balance sheet. The offsetting rights of the master netting arrangements can only be enforced if a predetermined event occurs in the future, such as a counterparty defaulting.

Cash collateral and financial instrument collateral

These amounts are received or pledged under master netting arrangements against the gross amounts of assets and liabilities. Financial instrument collateral typically comprises securities which can be readily liquidated in the event of counterparty default. The offsetting rights of the master netting arrangement can only be enforced if a predetermined event occurs in the future, such as a counterparty defaulting.

Note 24.Intangible assets

Accounting policy

​

​

​

Indefinite life intangible assets

Goodwill

Goodwill acquired in a business combination is initially measured at cost, generally being the excess of:

(i)

The consideration paid; over

(ii)

The net fair value of the identifiable assets, liabilities and contingent liabilities acquired.

Subsequently, goodwill is not amortised but rather tested for impairment. Impairment is tested at least annually or whenever there is an indication of impairment. An impairment charge is recognised when a cash generating unit’s (CGU) carrying value exceeds its recoverable amount. Recoverable amount means the higher of the CGU’s fair value less costs to sell and its value-in-use.

Westpac’s CGUs represent the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows from other assets or groups of assets. They reflect the level at which Westpac monitors and manages its operations.

Brand names

Brand names acquired in a business combination, including St.George, BT and BankSA, are initially recognised at cost. As these assets have been assessed as having indefinite useful lives they are not amortised but tested for impairment at least annually or whenever there is an indication of impairment. The useful life of each brand name intangible asset is also reviewed each period to determine whether events and circumstances continue to support the indefinite useful life assessment.

Finite life intangible assets

Finite life intangibles, such as computer software, are recognised initially at cost and subsequently at amortised cost less any impairment.

Note 24.Intangible assets (Continued)

Impairment testing and results

Impairment testing is performed at least once a year, or whenever there is an indication of impairment, by comparing the recoverable amount of each CGU with the carrying amount. For assets other than goodwill management also assess whether there is any indication that an impairment loss recognised in prior periods may no longer exist or may have decreased. If any such indication exists, the recoverable amount of the asset is estimated. The primary test for recoverable amount is determined based on value-in-use which refers to the present value of expected cash flows under its current use. Fair value less costs to sell is also considered for those CGUs where value-in-use is lower than carrying value. In the current year, this was not required to be considered.

Significant assumptions used in recoverable amount calculations

The assumptions made for the impairment testing of indefinite life of intangibles for each relevant significant CGU are provided in the following table and are based on past experience and management’s expectations for the future. In the current year and given the present economic environment, Westpac has reassessed these assumptions and revised them where necessary in order to provide a reasonable estimate of the value-in-use of the CGUs and Group.

a.Australian CGUs comprise Consumer and the CGUs within Business & Wealth.

Westpac discounts the projected cash flows by its adjusted pre-tax equity rate.

The cashflows used are based on approved forecasts. These forecasts utilise information about current and future economic conditions, observable historical information and management expectations of future business performance. The terminal growth rate represents the growth rate applied to extrapolate cash flows beyond the forecast period and reflects the lower end of the RBA’s target long-term inflation rate band. For all CGUs tested, the recoverability of goodwill is not reliant on any one particular assumption. There are no reasonably possible changes in assumptions for any significant CGU that would result in an indication of impairment or have a material impact on Westpac’s reported results.

NOTES TO THE FINANCIAL STATEMENTS

Note 25.Provisions, contingent liabilities, contingent assets and credit commitments

Accounting policy

​

Provisions

Provisions are recognised for present obligations arising from past events where a payment (or other economic transfer) is likely to be necessary to settle the obligation and can be reliably estimated.

Employee benefits – long service leave provision

Long service leave is granted to certain employees in Australia and New Zealand. The provision is calculated based on the expected payments. When payments are expected to be more than one year in the future, the provision is discounted to present value using assumptions for expected employee service, utilisation and average salary increases.

Provisions carried for long service leave are supported by an independent actuarial report.

Employee benefits – annual leave and other employee benefits provision

The provision for annual leave and other employee benefits (including wages and salaries, inclusive of non-monetary benefits, and any associated on-costs (e.g. payroll tax)) is calculated based on expected payments.

Provision for ECL on credit commitments

Westpac is committed to provide facilities and guarantees as explained below. The provision for ECL is calculated using the methodology described in Note 10.

Compliance, Regulation and Remediation provisions

The compliance, regulation and remediation provisions relate to matters of potential misconduct in providing services to customers identified both as a result of regulatory action and internal reviews. An assessment of the likely cost of these matters to Westpac (including applicable customer refunds) is made on a case-by-case basis and specific provisions are made where appropriate.

Contingent liabilities

Contingent liabilities are possible obligations whose existence will be confirmed only by uncertain future events, and present obligations where the transfer of economic resources is not probable or cannot be reliably measured. Contingent liabilities are not recognised in the balance sheet but are disclosed unless the outflow of economic resources is remote.

Undrawn credit commitments

Westpac enters into various arrangements with customers which are only recognised in the balance sheet when called upon. These arrangements include commitments to extend credit, bill endorsements, financial guarantees, standby letters of credit and underwriting facilities.

Contingent assets

Contingent assets are possible assets whose existence will be confirmed only by uncertain future events. Contingent assets are not recognised in the balance sheet but are disclosed if an inflow of economic benefits is probable.

Critical accounting assumptions and estimates

The financial reporting of provisions for litigation and non-lending losses and for compliance, regulation and remediation matters involves a significant degree of judgement in relation to identifying whether a present obligation exists and also in estimating the probability, timing, nature and quantum of the outflows that may arise from past events. These judgements are made based on the specific facts and circumstances relating to individual events.

NOTES TO THE FINANCIAL STATEMENTS

Note 25.

Provisions, contingent liabilities, contingent assets and credit commitments (Continued)

Provisions

Litigation, non-lending losses and remediation provisions

Provisions for the financial year 2025 include estimates of:

●Customer refunds associated with matters of potential historical misconduct;
●Costs of completing remediation programs; and
●Potential non-lending losses and costs connected with certain litigation and regulatory investigations.

It is possible that the final outcome could be below or above the provision, if the actual outcome differs from the assumptions used in estimating the provision. Remediation processes may change over time as further facts emerge and such changes could result in a change to the final exposure.

Certain litigation and regulatory matters

As at 30 September 2025, the Group held provisions in respect of potential non-lending losses and costs connected with certain litigation and regulatory matters, including:

●Civil penalty proceedings commenced by ASIC against Westpac on 4 September 2023, alleging contraventions under the National Credit Code (Credit Code) and National Consumer Credit Protection Act 2009 (Cth). The proceedings relate to system and operational failures and allege that Westpac did not respond to 277 online hardship applications between 2015 and 2023 within the time-frames required under the Credit Code. Westpac self-reported the incidents to ASIC and has remediated impacted customers. ASIC also alleges that Westpac failed to do all things necessary to ensure that credit activities were engaged in efficiently, honestly and fairly. The Court’s judgment is reserved following the hearing on liability and penalty on 26 May 2025.
●A class action commenced against Westpac and St.George Finance Limited (SGF) on 15 July 2020, in the Supreme Court of Victoria in relation to flex commissions paid to auto dealers from 1 March 2013 to 31 October 2018. Westpac and SGF settled the class action on 14 March 2025 without admission of liability. On 27 August 2025, the Court approved the settlement amount of $130 million.
●Agreed civil penalty proceedings between ASIC and RAMS Financial Group Pty Limited (RFG) relating to RFG’s oversight of conduct of RAMS third-party franchisees and franchisee employees who were authorised credit representatives of RFG between 3 June 2019 to 30 April 2023. On 24 October 2025, the Court delivered its judgement and imposed a penalty of $20 million plus costs.

Where matters have not been resolved, there remains uncertainty as to the expense that may be associated with these matters, including the approach that the relevant counterparty or Courts may take in relation to these matters, and the Court’s assessment of applicable fines, penalties, loss or damages. It is possible that the actual aggregate expense to Westpac associated with a Court determined resolution of these matters may be higher or lower than the provision.

Restructuring provisions

Westpac carries restructuring provisions for committed business restructures and branch closures. The provisions held primarily relate to staff separation costs and redundancies.

Lease restoration obligations

The lease restoration provision reflects an estimate of the cost of making good leasehold premises at the end of Westpac’s property leases.

Contingent liabilities

Regulatory investigations, reviews and inquiries

Domestic regulators, statutory authorities and other bodies, such as ASIC, the ACCC, APRA, AUSTRAC, BCCC, AFCA, the OAIC, the ATO and the Fair Work Ombudsman (FWO), as well as certain international regulators and other bodies such as the Reserve Bank of New Zealand, New Zealand Financial Markets Authority, New Zealand Commerce Commission, BPNG and its Financial Analysis & Supervision Unit, Reserve Bank of Fiji, and the SEC, from time to time conduct investigations, reviews or inquiries (some of which may be industry wide). These activities can cover a range of matters (including potential contraventions and non-compliance) that involve, or may in the future, involve the Group.

These currently include:

●An investigation by the FWO in relation to Westpac’s self-disclosed remediation program regarding employee pay-related entitlements. Westpac considers enforcement action against it likely, and could include an Enforceable Undertaking; and
●Regulatory investigations, reviews or inquiries into other areas such as the AML/CTF Program and associated processes and procedures, compliance with industry codes, monitoring of certain consumer transactions, consumer lending conduct, responsible lending and compliance with lending obligations, consumer credit contracts, banking products and services, and hardship processes.

It is uncertain what (if any) actions will result following the conclusion of these investigations or matters. No provisions have yet been made in relation to any financial liability that might arise, or costs that may be incurred in the event proceedings are pursued in relation to the matters outlined above. Such investigations, reviews or inquiries, or risk-based decisions taken by Westpac regarding relevant businesses, have previously resulted, and/or may in the future result in litigation (including class action proceedings and criminal proceedings), significant fines and penalties, infringement notices, enforcement action including enforceable undertakings, requirement to undertake a review, referral to the relevant Commonwealth or State Director of Public Prosecutions for consideration for criminal prosecution, imposition of capital or liquidity requirements, licence revocation, suspension or variation, customer remediation or other sanctions or actions being taken by regulators or other parties. Investigations have in some instances resulted, and could in the future result, in findings of a significant number of breaches of obligations. This in turn could lead to significant financial and other penalties. Prior penalties and contraventions by Westpac in relation to similar issues can also affect penalties that may be imposed. Reliance on third parties and any contributing actions of third parties may not mitigate penalties.

Litigation

There are ongoing Court proceedings, claims and possible claims against the Group. Contingent liabilities exist in respect of actual and potential claims and proceedings, including those listed below.

Class actions

In addition to the class action litigation noted under Provisions, above:

●Westpac is defending a class action proceeding which was commenced in December 2019 in the Federal Court of Australia on behalf of certain investors who acquired an interest in Westpac securities between 30 June 2014 and 19 November 2019. The proceeding involves allegations relating to market disclosure issues connected to Westpac’s monitoring of financial crime over the relevant period and matters which were the subject of the AUSTRAC civil proceedings. The damages sought on behalf of members of the class have not yet been specified. However, in the course of a procedural hearing in August 2022, the applicant indicated that a preliminary estimate of the losses that may be alleged in respect of a subset of potential group members exceeded $1 billion. While it remains unclear how the applicant will ultimately formulate their estimate of alleged damages claimed on behalf of group members, it is possible that the claim may be higher (or lower) than the amount referred to above. Given the time period and the nature of the claims alleged to be in question, along with the reduction in our market capitalisation at the time of the commencement of the AUSTRAC civil proceedings, it is likely that any total alleged damages (when, and if, ultimately articulated by the applicant) will be significant. Westpac continues to deny both that its disclosure was inappropriate and, as such, that any group member has incurred damage. The Court has made orders for a hearing to commence on 5 April 2027 with an estimated duration of six weeks; and
●Disputes have been raised by franchisees who were exited by RFG, including the commencement of a class action in May 2024. The class action and an additional proceeding commenced by an exited franchisee have been listed for hearing to commence on 31 August 2026.

NOTES TO THE FINANCIAL STATEMENTS

Note 25.

Provisions, contingent liabilities, contingent assets and credit commitments (Continued)

Internal reviews and remediation

As in prior periods, Westpac is continuing to undertake a number of reviews to identify and resolve issues that have the potential to impact us, our customers, employees, other stakeholders and our reputation. These internal reviews continue to identify issues, in respect of which, we are taking, or will take, action so that Westpac, our customers and employees (as applicable) are not disadvantaged from certain past practices, including by making compensation/remediation payments and providing refunds where appropriate. These issues include, among other things, consumer lending conduct; responsible lending and compliance with lending obligations; hardship processes; sufficiency of training, policies, processes and procedures; AML/CTF Program and associated processes and procedures; use of our products or services for an improper purpose; product disclosure; protection and destruction of personal information; and impacts from inadequate product governance, including the way some product terms and conditions are operationalised.

By undertaking these reviews, we can also improve our processes and controls, including those of our contractors, agents, and authorised credit representatives. An assessment of the Group’s likely loss has been made on a case-by-case basis for the purpose of the financial statements but cannot always be reliably estimated. Even where Westpac has remediated or compensated customers, employees or issues, there can still be the risk of regulators challenging the basis, scope or pace of remediation, taking enforcement action (including seeking enforceable undertakings and contrition payments), or imposing fines/penalties or other sanctions, including civil or criminal prosecutions. Contingent liabilities may exist in respect of actual or potential claims or proceedings (which could be brought by customers, individuals, employees/unions, regulators or criminal prosecutors), compensation/remediation payments and/or refunds identified as part of these reviews.

Contingent levies

The Group is subject to a number of regulatory levies, which may be imposed at the discretion of the relevant regulating body. These include levies that fund the Financial Claims Scheme and the Compensation Scheme of Last Resort.

Exposures to third parties relating to divested businesses

The Group has potential exposures relating to warranties, indemnities and other commitments it has provided to third parties in connection with various divestments of entities, businesses and assets. The warranties, indemnities and other commitments cover a range of matters, conduct and risks. We have made payments under these indemnities and are in discussions with one or more parties in relation to claims made, and potential claims, under these arrangements. Provisions have been raised for matters where a present obligation exists, and a probable settlement can be reliably estimated.

Contingent tax risk

Tax and regulatory authorities in Australia and in other jurisdictions review, in the normal course of business, the direct and indirect taxation treatment of transactions (both historical and present-day transactions) undertaken by the Group. The Group also responds to various notices and requests for information it receives from tax and regulatory authorities.

These reviews, notices and requests may result in additional tax liabilities (including interest and penalties).

Westpac has assessed these and other taxation matters arising in Australia and elsewhere, including seeking independent advice.

Clearing and settlement obligations

Westpac is subject to the rules governing clearing and settlement activities under which loss sharing arrangements may arise. This includes the requirements of central clearing houses where the Group has made contributions to a default fund. In the event of a default of another clearing member, the Group could be required to make additional default fund contributions.

Parent entity guarantees and undertakings to subsidiaries

Westpac Banking Corporation, as the parent entity of Westpac, provides letters of comfort in respect of certain subsidiaries in the normal course of business. These recognise that Westpac has a responsibility that those subsidiaries continue to meet their obligations.

Previously the parent entity also provided guarantees to certain wholly-owned subsidiaries which are Australian financial services or credit licensees to comply with legislative requirements. All but two of these guarantees were capped at $20 million per year and two specific guarantees were capped at $2 million. In 2025, these guarantees have been either replaced by a professional indemnity insurance policy or have been cancelled.

Provisions, contingent liabilities, contingent assets and credit commitments (Continued)

Contingent assets

The credit commitments shown in the following table also constitute contingent assets. These commitments would be classified as loans in the balance sheet on the contingent event occurring.

Undrawn credit commitments

Westpac enters into various arrangements with customers that constitute contingent assets. If a specified contingent event occurs, these commitments will be called upon and recognised on the balance sheet as loans.

Any associated cash outflows expose Westpac to liquidity risk, while the resulting receivable exposes Westpac to credit risk should the counterparty fail to repay amounts owed as they become due. Westpac’s maximum exposure to credit losses is the contractual or notional amount of the arrangement, noting that some credit commitments can be cancelled by Westpac at any time, and a significant portion are expected to expire without being drawn upon. As a result, notional amounts do not necessarily reflect future cash requirements.

Westpac applies the same credit policies when entering into these arrangements as it does for on balance sheet instruments. Refer to Note 11 and Note 21 of the 2025 Annual Report for further details of credit risk and liquidity risk management, respectively.

Undrawn credit commitments, excluding derivatives, are disclosed in the below table:

●Financial guarantees, letters of credit and other credit substitutes support the financial obligations of customers to third parties. Utilisation of these contracts is generally dependent on the creditworthiness of the customer. The Group may hold cash as collateral for certain financial guarantees issued;
●Performance-related contingencies support the non-monetary obligations of customers to third parties, where payment will generally need to be made if a customer fails to fulfil a non-monetary contractual obligation to that third party;
●Remaining commitments to extend credit mainly comprises various forms of credit facilities.

The composition of undrawn credit commitments has been revised to better reflect the nature of the types of commitments provided. Comparatives have been revised to align with current period presentation.

b.

Commitments to extend credit include all obligations on the part of the Group to provide credit facilities. As facilities may expire without being drawn upon, the notional amounts do not necessarily reflect future cash requirements. In addition to the commitments disclosed above, $7.4 billion (2024: $6.0 billion) for the Group and $6.3 billion (2024: $5.1 billion) for the Parent Entity of credit exposures were offered and accepted but still revocable. These represent part of Westpac Group’s maximum credit exposure to credit risk.

NOTES TO THE FINANCIAL STATEMENTS

CAPITAL AND DIVIDENDS

Note 26.Shareholders’ equity

Accounting policy

​

Share capital

Ordinary shares are recognised at the amount paid up per ordinary share, net of directly attributable issue costs. Treasury shares are shares in the Parent Entity, purchased by the Parent Entity or other entities within Westpac. These shares are adjusted against share capital as the net of the consideration paid to purchase the shares and, where applicable, any consideration received from the subsequent sale or reissue of these shares.

Non-controlling interests

Non-controlling interests represent the share in the net assets of subsidiaries attributable to equity interests that are not owned directly or indirectly by the Parent Entity.

Reserves

Foreign currency translation reserve

Exchange differences arising on translation of Westpac’s foreign operations, and any offsetting gains or losses on hedging the net investment are reflected in the foreign currency translation reserve. A cumulative credit balance in this reserve would not normally be regarded as being available for payment of dividends until such gains are realised and recognised in the income statement on sale or disposal of the foreign operation.

Debt securities at FVOCI reserve

This reserve comprises the changes in fair value of debt securities measured at FVOCI (except for interest income, impairment charges and FX gains and losses which are recognised in the income statement), net of any related hedge accounting adjustments and tax. These changes are transferred to the income statement when the asset is disposed.

Equity securities at FVOCI reserve

This reserve comprises the changes in fair value of equity securities measured at FVOCI, net of tax. These changes are not transferred to the income statement when the asset is disposed.

Cash flow hedge reserve

This comprises the fair value gains and losses associated with the effective portion of designated cash flow hedging instruments, net of tax.

Share-based payment reserve

This comprises the fair value of equity-settled share-based payments recognised as an expense.

Other reserves

Other reserves for the Parent Entity relate to certain historic internal group restructurings performed at fair value. The reserve is eliminated on consolidation.

Other reserves for Westpac consist of transactions relating to changes in the Parent Entity’s ownership of a subsidiary that do not result in a loss of control.

The amount recorded in other reserves reflects the difference between the amount by which NCI are adjusted and the fair value of any consideration paid or received.

Discretionary distributions on PPS are recognised in equity when paid.

Ordinary shares

Westpac does not have authorised capital and the ordinary shares have no par value. Ordinary shares entitle the holder to participate in dividends and, in the event of Westpac winding up, to a share of the proceeds in proportion to the number of and amounts paid on the shares held.

Each ordinary share entitles the holder to one vote, either in person or by proxy, at a shareholder meeting.

Note 27.Capital adequacy

APRA is the prudential regulator of ADIs including Westpac. APRA measures an ADI’s regulatory capital using the following measures:

Level of capital

Definition

Common Equity Tier 1 (CET1) Capital

Comprises the highest quality components of capital that consists of paid-up share capital, retained profits and certain reserves, less certain intangible assets, capitalised expenses and software, and investments and retained profits in insurance and funds management subsidiaries that are not consolidated for capital adequacy purposes.

Tier 1 Capital

The sum of CET1 and Additional Tier 1 (AT1) Capital. AT1 Capital comprises high quality components of capital that consists of certain securities not included in CET1, but which include loss absorbing characteristics. AT1 instruments convert into equity and absorb losses when certain triggers are met.

Total Capital

The sum of Tier 1 Capital and Tier 2 Capital. Tier 2 Capital includes subordinated instruments and other components of capital that, to varying degrees, do not meet the criteria for Tier 1 Capital, but nonetheless contribute to the overall strength of an ADI and its capacity to absorb losses when certain triggers are met.

Leverage ratio

The leverage ratio is defined by APRA as Tier 1 capital divided by the “Exposure measure” and is expressed as a percentage. “Exposure measure” includes on- balance sheet exposures, derivatives exposures, securities financing transaction (SFT) exposures, and other off-balance sheet exposures.

​

Under APRA’s Prudential Standards, Australian ADIs, including Westpac, are required to maintain minimum Prudential Capital Requirements expressed as a percentage of total risk weighted assets as follows:

●CET1 Capital ratio of at least 4.5%;
●Tier 1 Capital ratio of at least 6.0%; and
●Total Capital ratio of at least 8.0%.

APRA may also require ADIs, including Westpac, to meet Prudential Capital Requirements above the industry minimum. APRA does not allow the Prudential Capital Requirements for individual ADIs to be disclosed. APRA also requires ADIs to hold additional CET1 buffers comprising of:

●A capital conservation buffer of 4.75% that includes a 1% surcharge for ADIs designated by APRA as D-SIBs. APRA has determined that Westpac is a D-SIB; and
●Countercyclical capital buffer of 1.0%. The countercyclical buffer is set on a jurisdictional basis and APRA is responsible for setting the requirement in Australia. The countercyclical buffer requirement is currently set to the default of 1.0% for Australian exposures, however this may be varied by APRA in the range of 0% to 3.5%.

Collectively, the above buffers are referred to as the “Capital Buffer”. Should the CET1 capital ratio fall within the capital buffer range, restrictions on the distribution of earnings will apply. This includes restrictions on the amount of earnings that can be distributed through dividends, AT1 Capital distributions and discretionary staff bonuses.

The Total CET1 Requirement for Westpac is at least 10.25%, (based on an industry minimum CET1 requirement of 4.5% plus a Capital Buffer of at least 5.75% applicable to D-SIBs), the Tier 1 Capital Ratio requirement is at least 11.75% and the Total Capital Ratio requirement is at least 13.75%1.

In addition, APRA’s capital framework also requires an ADI to maintain a minimum leverage ratio of 3.5%. APRA may also vary the minimum leverage ratio for an individual ADI.

Westpac’s capital adequacy was compliant with APRA’s requirements throughout 2025.

APRA has announced changes to banks’ capital requirements with effect from 1 January 2027. This includes changes to CET1, Tier 1, Total capital and the Leverage ratio.

Capital management strategy

Westpac’s capital management strategy is reviewed on an ongoing basis, including through an annual Internal Capital Adequacy Assessment Process (ICAAP). Key features include:

●The development of a capital management strategy, including consideration of regulatory capital minimums, capital buffers and contingency plans;
●Consideration of regulatory capital requirements and the perspectives of external stakeholders including rating agencies as well as equity and debt investors; and
●A stress testing framework that tests our resilience under a range of adverse economic scenarios.

The Board has determined a target post dividend CET1 capital ratio of above 11.25% in normal operating conditions. This target includes consideration of APRA’s increase in the minimum CET1 ratio of 0.25% to 10.50% effective 1 January 2027 and replaces the previous CET1 capital operating range of between 11.00% and 11.50%.

Noting that APRA may apply higher requirements for an individual ADI.

​

The Board has determined a final fully franked dividend of 77 cents per share, to be paid on 19 December 2025 to shareholders on the register at the record date of 7 November 2025.

Shareholders can choose to receive their dividends as cash or reinvest their dividend in additional shares under the Dividend Reinvestment Plan.

The Board has determined to satisfy the Dividend Reinvestment Plan (DRP) for the 2025 final ordinary dividend by arranging for the purchase of shares in the market by a third party. The market price used to determine the number of shares provided to DRP participants will be set over the 15 trading days commencing 12 November 2025 and will not include a discount.

Details of dividends recognised during the year are provided in the statement of changes in equity.

Australian franking credits available to the Parent Entity for subsequent years are $3,714 million (2024: $3,504 million, 2023: $3,520 million). This is calculated as the year end franking credit balance, adjusted for the Australian current tax liability and the proposed 2025 final dividend.

New Zealand imputation credits

New Zealand imputation credits of NZ$0.06 (2024: NZ$0.06, 2023: NZ$0.07) per share will be attached to the proposed 2025 final dividend. New Zealand imputation credits available to the Parent Entity for subsequent years are NZ$332 million (2024: NZ$374 million, 2023: NZ$557 million). This is calculated on the same basis as the Australian franking credits but using the New Zealand current tax liability.

GROUP STRUCTURE

Note 29.Investments in subsidiaries and associates

Accounting policy

​

Subsidiaries

Westpac’s subsidiaries are entities which it controls and consolidates as it is exposed to, or has rights to, variable returns from the entity, and can affect those returns through its power over the entity.

When Westpac ceases to control a subsidiary, any retained interest in the entity is remeasured to fair value, with any resulting gain or loss recognised in the income statement.

Changes in Westpac’s ownership interest in a subsidiary which do not result in a loss of control are accounted for as transactions with equity holders in their capacity as equity holders.

In the Parent Entity’s financial statements, investments in subsidiaries are initially recorded at cost and are subsequently held at the lower of cost and recoverable amount.

All transactions between Westpac entities are eliminated on consolidation.

Associates

Associates are entities in which Westpac has significant influence, but not control, over the operating and financial policies. Westpac accounts for associates using the equity method. The investments are initially recognised at cost (except where recognised at fair value due to a loss of control of a subsidiary), and increased (or decreased) each year by Westpac’s share of the associate’s profit (or loss). Dividends received from the associate reduce the investment in the associate.

​

Overseas companies predominantly carry on business in the country of incorporation. For unincorporated entities, ‘Country of incorporation’ refers to the country where business is carried on. The financial years of all controlled entities are the same as that of Westpac unless otherwise stated. From time to time, Westpac consolidates a number of unit trusts where Westpac has variable returns from its involvement with the trusts, and has the ability to affect those returns through its power over the trusts. These unit trusts are excluded from the table.

A complete list of controlled entities can be found in the Consolidated Entity Disclosure Statement. The following table includes the material controlled entities of Westpac as at 30 September 2025.

Note 30.Structured entities

Accounting policy

​

Structured entities are generally created to achieve a specific, defined objective and their operations are restricted such as only purchasing specific assets. Structured entities are commonly financed by debt or equity securities that are collateralised by and/or indexed to their underlying assets. The debt and equity securities issued by structured entities may include tranches with varying levels of subordination.

Structured entities are classified as subsidiaries and consolidated if they meet the definition in Note 29. If Westpac does not control a structured entity then it will not be consolidated.

​

Westpac engages in various transactions with both consolidated and unconsolidated structured entities that are mainly involved in securitisations, asset backed and other financing structures and managed funds.

Consolidated structured entities

Securitisation and covered bonds

Westpac uses structured entities to securitise its financial assets, including two covered bond programs, to assign pools of residential mortgages to bankruptcy remote structured entities. Refer to Note 15 for further details.

Westpac managed funds

Westpac acts as the responsible entity and/or fund manager for various investment management funds. As fund manager, if Westpac is deemed to be acting as a principal rather than an agent then it consolidates the fund. The principal versus agent decision requires judgement of whether Westpac has sufficient exposure to variable returns.

Non-contractual financial support

Westpac does not provide non-contractual financial support to these consolidated structured entities.

Unconsolidated structured entities

Westpac has interests in various unconsolidated structured entities including debt or equity instruments, guarantees, liquidity and other credit support arrangements, lending, loan commitments, certain derivatives and investment management agreements.

Interests exclude non-complex derivatives (e.g. interest rate or currency swaps), instruments that create, rather than absorb, variability in the entity (e.g. credit protection under a credit default swap), and lending to a structured entity with recourse to a wider operating entity, not just the structured entity.

Westpac’s main interests in unconsolidated structured entities, which arise in the normal course of business, are:

Trading securities

Westpac actively trades interests in structured entities and normally has no other involvement with the structured entity. Westpac earns interest income on these securities and also recognises fair value changes through trading income in non-interest income.

Investment securities

Westpac holds mortgage-backed securities for liquidity purposes and Westpac normally has no other involvement with the structured entity. These assets are highly-rated, investment grade and eligible for repurchase agreements with the RBA or another central bank. Westpac earns interest income and net gains or losses on selling these assets are recognised in the income statements.

Loans and other credit commitments

Westpac lends to unconsolidated structured entities, subject to Westpac’s collateral and credit approval processes, in order to earn interest and fee income. The structured entities are mainly property trusts, securitisation entities and those associated with project and property financing transactions.

Investment management agreements

Westpac manages funds that provide customers with investment opportunities. Westpac earns management fee income which is recognised in non-interest income.

Westpac may also retain units in these investment management funds. Westpac earns fund distribution income and recognises fair value movements through non-interest income.

The following tables show Westpac’s interests in unconsolidated structured entities and its maximum exposure to loss in relation to those interests. The maximum exposure does not take into account any collateral or hedges that will reduce the risk of loss.

●For on-balance sheet instruments, including debt and equity instruments in and loans to unconsolidated structured entities, the maximum exposure to loss is the carrying value.
●For off-balance sheet instruments, including liquidity facilities, loan and other credit commitments and guarantees, the maximum exposure to loss is the notional amounts.

Note 31.Share-based payments

Accounting policy

​

Westpac enters into various share-based payment arrangements with its employees as a component of overall compensation for services provided. Share-based payment arrangements comprise rights to receive shares for free (share rights) and restricted shares (issued at no cost). Share-based payment arrangements typically require a specified period of continuing employment (the service period or vesting period) and may include performance targets (vesting conditions). Specific details of each arrangement are provided below.

Share-based payments must be classified as either cash-settled or equity-settled arrangements. Westpac’s significant arrangements are equity-settled, as Westpac is not obliged to settle in cash.

Share rights

Share rights are equity-settled arrangements. The fair value is measured at grant date and is recognised as an expense over the service period, with a corresponding increase in the share-based payment reserve in equity.

The fair values of share rights are estimated at grant date using a binomial/Monte Carlo simulation pricing model which incorporates the vesting and market-related performance targets of the grants. The fair value of share rights excludes non-market vesting conditions such as employees’ continuing employment by Westpac. The non-market vesting conditions are instead incorporated in estimating the number of share rights that are expected to vest and are therefore recognised as an expense. At each reporting date the non-market vesting assumptions are revised and the expense recognised each year takes into account the most recent estimates. The market-related assumptions are not revised each year as the fair value is not re-estimated after the grant date.

Up to 1 January 2023 share rights were issued under the Westpac Long Term Variable Reward Plan (LTVR) and Westpac Performance Plan (WPP). From 1 January 2023 share rights have been issued under the Equity Incentive Plan (EIP). Refer below for further details.

Restricted shares

Restricted shares are accounted for as an equity-settled arrangement. The fair value of shares allocated to employees for nil consideration is recognised as an expense over the vesting period with a corresponding increase in the share-based payments reserve in equity. The fair value of ordinary shares issued to satisfy the obligation to employees is measured at grant date and is recognised as a separate component of equity.

Up to 1 January 2023 restricted shares were issued under the Restricted Share Plan (RSP). From 1 January 2023 restricted shares have been issued under the Equity Incentive Plan (EIP). Refer below for further details.

Equity Incentive Plan (EIP)

The Equity Incentive Plan (EIP) was introduced effective 1 January 2023 and is a consolidated plan that replaced the RSP, WPP and LTVR plans. Existing allocations under the RSP, WPP and LTVR continue to be governed by their respective plan rules, however, all grants from 1 January 2023 are made under the EIP. Securities issued under the EIP include restricted shares, unhurdled share rights, performance rights and restricted rights. The underlying terms of the EIP are similar to RSP, WPP and LTVR and are accounted for as equity-settled arrangements in line with the share rights and restricted shares specified above.

In respect of the above mentioned plans, the Board has discretion to adjust unvested allocations, including to zero, in specified circumstances. Clawback may also apply to vested awards, to the extent legally permissible and practicable.

Employee share plan (ESP)

The value of shares expected to be allocated to employees for nil consideration is recognised as an expense over the financial year and provided for as other employee benefits. The fair value of any ordinary shares purchased on market or issued to satisfy the obligation to employees is recognised in equity.

a.The Board has discretion to adjust the number of restricted shares, unhurdled share rights, performance rights and restricted rights downwards, including to zero, in specified circumstances including serious misconduct, if serious circumstances or new information come to light which mean that in the Board’s view all or part of the award was not appropriate, or where required by law or prudential standards. The Board will typically apply the adjustment to unvested LTVR where an adjustment to current and deferred STVR is considered insufficient or unavailable. Clawback may also apply to vested LTVR, to the extent legally permissible and practicable.
b.Excluding the UNITE Award that is granted as share rights under the EIP and is subject to internal performance measures.
c.Vested share rights granted after July 2015 under the 2020 to 2023 LTVR awards and unhurdled WPP/EIP awards may be exercised up to a maximum of 15 years (generally 10 years for NZ) from their commencement date. Vested share rights under the 2024 and 2025 LTVR award (performance rights and restricted rights) are exercisable up to 2 years after the vesting date.
d.For LTVR restricted rights, dividend equivalent payments (DEP) are accrued for the vesting period. For LTVR performance rights, DEP are only accrued for the further deferral period after the performance period. These DEP are calculated by multiplying the number of LTVR restricted or performance rights eligible to vest by the declared dividend price on each respective record date during the applicable period. The calculation excludes franking credits. They are paid at the end of the deferral period.

a.The market price per share for the allocation is based on the five day volume-weighted average price up to the grant date.

The 2024 ESP award was satisfied through the purchase of shares on market.

The liability accrued for the ESP at 30 September 2025 was $28 million (2024: $28 million) and was provided for as other employee benefits.

viii.

Other plans

Westpac also provides share-based plans for small, specialised parts of the Group. The benefits under these plans are directly linked to growth and performance of the relevant part of the business. The plans, individually and in aggregate, are not material to Westpac in terms of expenses and dilution of earnings.

The names of all persons who hold share options and/or rights currently on issue are entered in Westpac’s register of option holders which may be inspected at MUFG Corporate Markets (AU) Limited, Liberty Place, Level 41, 161 Castlereagh Street, Sydney, New South Wales.

ix.

Fair value assumptions

The fair value of share rights have been independently calculated at their respective grant dates.

The fair value of share rights with performance targets based on relative TSR takes into account the average TSR outcome determined using a Monte Carlo simulation pricing model.

The fair value of share rights without TSR based performance targets (i.e. unhurdled share rights and restricted rights) have been determined with reference to the share price at grant date. A discount rate reflecting the expected dividend yield over their vesting periods also applies to unhurdled share rights and LTVR performance rights.

Other significant assumptions include:

●Risk-free rates of return of 3.3%-3.8% applied to TSR-hurdled grants;
●The dividend yield on Westpac shares applied to TSR-hurdled grants ranged from 4.0%-5.0% for those issued under the LTVR and for those issued under the EIP;
●Volatility in Westpac’s TSR of 20%-21%, applied to TSR-hurdled grants; and
●Volatilities of, and correlation factors between, TSR of the comparator group and Westpac for TSR-hurdled grants.

NOTES TO THE FINANCIAL STATEMENTS

Note 32.Superannuation commitments

Accounting policy

​

Westpac recognises an asset or a liability for its defined benefit schemes, being the net of the defined benefit obligations and the fair value of the schemes’ assets. The defined benefit obligation is calculated as the present value of the estimated future cash flows, discounted using high-quality long dated corporate bond rates.

The superannuation expense is recognised in operating expenses and remeasurements are recognised through OCI.

​

Westpac had the following defined benefit plans at 30 September 2025:

​

The defined benefit sections of the schemes are closed to new members. Westpac has no obligation beyond the annual contributions for the accumulation or defined contribution sections of the schemes.

The WGP is Westpac’s principal defined benefit plan and is managed and administered in accordance with the terms of its trust deed and relevant legislation in Australia. Its defined benefit liabilities are based on salary and length of membership for active members and inflation in the case of pensioners.

The defined benefit schemes expose Westpac to the following risks:

●Discount rate – reductions in the discount rate would increase the present value of the future payments;
●Inflation rate – increases in the inflation rate would increase the payments to pensioners;
●Investment risk – lower investment returns would increase the contributions needed to offset the shortfall;
●Mortality risk – members may live longer than expected extending the cash flows payable by Westpac;
●Behavioural risk – higher proportion of members taking some of their benefits as a pension rather than a lump sum would increase the cash flows payable by Westpac; and
●Legislative risk – legislative changes could be made which increase the cost of providing defined benefits.

Investment risk is managed by setting benchmarks for the allocation of plan assets between asset classes. The long-term investment strategy will often adopt relatively high levels of equity investment in order to:

●Secure attractive long-term investment returns; and
●Provide an opportunity for capital appreciation and dividend growth, which gives some protection against inflation.

Funding recommendations for the WGP, WNZS and the UKSS are made based on actuarial valuations. The funding valuations of the defined benefit plans are based on different assumptions to the calculation of the defined benefit surplus/deficit for accounting purposes. Based on the most recent valuations, the defined benefit plan assets are adequate to cover the present value of the accrued benefits of all members with a combined surplus of $161 million (2024: $140 million). Current contribution rates are as follows:

●WGP – contributions are made to the WGP at the rate of 16.9% of members’ salaries;
●WNZS – contributions are made to the WNZS at the rate of 17.4% of members’ salaries; and
●UKSS – not required to make contributions under the 2024 actuarial assessment.

On 10 September 2025, Westpac Bank - PNG - Limited (WPNG) paid PGK8 million to minority shareholders, on behalf of the Parent Entity, to acquire 1.09% in WPNG. This was in lieu of the Parent Entity receiving unpaid dividends from WPNG and as a result was a non-cash transaction for the Parent Entity.

On 11 September 2024, WPNG paid PGK66 million to minority shareholders, on behalf of the Parent Entity, to acquire 8.74% in WPNG. This was also in lieu of the Parent Entity receiving unpaid dividends from WPNG and as a result was a non-cash transaction for the Parent Entity.

On 18 December 2023, $802 million of WCN6 were transferred to the WCN6 nominated party for $100 each pursuant to the WCN10 reinvestment offer. Those WCN6 were subsequently redeemed and cancelled by Westpac. On 31 July 2024, Westpac redeemed the remaining outstanding WCN6.

Management’s report on internal control over financial reporting

The following report is required by rules of the US Securities and Exchange Commission.

The management of Westpac is responsible for establishing and maintaining adequate internal control over financial reporting for Westpac as defined in Rule 13a - 15(f) under the Securities Exchange Act of 1934, as amended. Westpac’s internal control system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with applicable accounting standards.

Westpac’s internal control over financial reporting includes policies and procedures that: pertain to the maintenance of records that in reasonable detail accurately reflect the transactions and dispositions of the assets of Westpac and its consolidated entities; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with applicable accounting standards, and that receipts and expenditures of Westpac are being made only in accordance with authorizations of management and directors of Westpac and its consolidated entities; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the assets of Westpac and its consolidated entities that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Westpac management, with the participation of the CEO and CFO, assessed the effectiveness of Westpac’s internal control over financial reporting as of 30 September 2025 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in its 2013 Internal Control Integrated Framework. Based on this assessment, management has concluded that Westpac’s internal control over financial reporting as of 30 September 2025 was effective.

The effectiveness of Westpac’s internal control over financial reporting as of 30 September 2025 has been audited by KPMG, an independent registered public accounting firm, as stated in its report which is included herein.

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheet of Westpac Banking Corporation and its subsidiaries (the Company) as of September 30, 2025, the related consolidated income statement, statement of comprehensive income, statement of changes in equity, and cash flow statement for the year then ended and the related notes (collectively, the ‘consolidated financial statements’). We also have audited the Company’s internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of September 30, 2025, and the results of its operations and its cash flows for the year then ended, in conformity with Australian Accounting Standards as issued by the Australian Accounting Standards Board and IFRS Accounting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

​

​

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s report on internal control over financial reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audit of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the

amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Supplemental Information

The parent entity only information on the face of the consolidated financial statements and other parent entity only disclosures in the notes to the financial statements (the ‘supplemental information’) have been subjected to audit procedures performed in conjunction with the audit of the Company’s consolidated financial statements. The supplemental information is the responsibility of the Company’s management. Our audit procedures included determining whether the supplemental information reconciles to the consolidated financial statements or the underlying accounting and other records, as applicable, and procedures to test the completeness and accuracy of the information presented in the supplemental information. The supplemental information, which is prepared for purposes of additional analysis, is presented on a basis that differs from the consolidated financial statements and is not a required part of the consolidated financial statements presented in accordance with Australian Accounting Standards as issued by the Australian Accounting Standards Board and IFRS Accounting Standards as issued by the International Accounting Standards Board. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the consolidated financial statements as a whole.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Provisions for expected credit losses on loans and credit commitments (ECL)

As discussed in Note 10 to the consolidated financial statements, the provision for ECL was $4,978 million for the Company at 30 September 2025. The Company uses models that estimate ECL using three main components: probability of default (PD), loss given default (LGD) and exposure at default (EAD). The Company applies forward-looking economic scenarios and associated probability weights to its models when determining an ECL estimate.

We identified the assessment of the provision for ECL as a critical audit matter. A high degree of audit effort, including specialised skills and knowledge, was required because of the significant measurement uncertainty involved in the Company’s estimation of ECL. Subjective and complex auditor judgement was required to assess the following:

●the Company’s modelled estimations of ECL due to the inherently judgmental and complex nature of the models, namely those used to derive the PD, LGD and EAD, and key associated model assumptions. Certain models and model assumptions are the key drivers of complexity and measurement uncertainty, and minor changes to the model assumptions could have a significant effect on the Company’s calculation of the provision for ECL; and
●the Company’s economic judgements, including the severity of the forward-looking downside economic scenario and the probability weightings used in the models.

The following are the primary procedures we performed to address this critical audit matter:

●We evaluated the design and tested the operating effectiveness of certain internal controls related to the ECL estimation process. This included certain controls relating to:

‒

model validation and monitoring;

‒

credit reviews that determine customer risk grades (CRGs); and

‒

the selection of the downside economic scenario and probability weightings.

●We involved our credit risk professionals with specialised skills and knowledge who assisted in evaluating the Company’s models and associated model assumptions as follows:

‒

evaluating the Company’s methodology used in the models to derive the PD, LGD and EAD and associated model assumptions against criteria in the accounting standards and industry practice;

‒

inspecting model code for the calculation of certain model components to assess its consistency with the Company’s modelling methodology;

‒

reperforming the model output for a selection of models using the Company’s documented methodology and comparing our output with the Company’s outputs; and

‒

reperforming model monitoring for a selection of the current models to evaluate the models’ performance.

●For a selection of customers in the business portfolios, we challenged the Company’s assessment of CRGs using relevant information in the loan file, including the customer’s financial position, to inform our overall assessment of the CRG against the Company’s policies.
●We involved our economic and credit risk professionals with specialised skills and knowledge, who assisted in challenging the macroeconomic variable forecasts against external economic data, evaluating the severity of the downside economic scenario and evaluating the probability weights.

​

We have served as the Company’s auditor since 2025.

144 WESTPAC GROUP 2025 ANNUAL REPORT ABOUT WESTPAC As Australia's first bank, we've been taking action to support people, businesses and communities for more than 200 years. Established in New South Wales in 1817, Westpac has grown to be one of Australia’s largest companies and employers. We’re proud to contribute to the prosperity of Australia and New Zealand. We support 13 million customers with a range of banking products and services, including helping them into homes, starting and growing businesses and supporting large corporates with their banking needs. We help foster stronger, more inclusive communities by promoting financial inclusion and literacy, investing in regional banking services and respecting human rights. Since founding our first charity in 1879, we've broadened our social impact through the independent Foundations and Trusts1 . These have contributed more than $100 million in the past decade to create meaningful change in people’s lives. For our 35,000 employees, we strive to create a workplace where they feel valued, inspired and motivated to reach their potential. As part of our environmental commitment, we support businesses in transitioning to a low-carbon future and adapting to climate change, while continuing to reduce our operational emissions and build climate resilience. This year, we paid $6.6 billion in salaries, $5.2 billion in shareholder dividends, $3.5 billion in taxes and levies and spent $4.74 billion with suppliers inside Australia2 .

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 145 OPERATING ENVIRONMENT1 Australian economy recovering despite productivity challenges The Australian economy is showing signs of improvement after a sustained period of below trend growth. However, the transition from the public to the private sector as the dominant driver of activity has been more challenging than expected. GDP growth is improving and expected to rise to 2.4% in 2026. Stronger growth should be underpinned by rising real wages, falling interest rates and a robust labour market. Productivity growth remains elusive with improvement requiring a coordinated response across both public and private sectors. Households navigate uneven recovery After an extended period of cost-of-living pressures, Australian households have begun to experience some relief. Real disposable incomes are rising, supported by easing inflation, declining interest rates and steady wage growth. Spending has recovered yet consumers remain cautious. Mortgage stress remains evident but has started to decline. Both demand and supply side factors are contributing to housing under-supply. This structural imbalance is expected to persist with house prices and credit demand expected to increase by 9% and 6.5% respectively in 2026. Business conditions improve as SMEs show green shoots Australian businesses have begun to emerge from a period of subdued activity, supported by easing inflation and interest rates. A recovery is underway though it remains uneven as the economy transitions from public to private sector led growth. Larger businesses have fared better than small and medium-sized businesses (SME). However, the share of SMEs experiencing an improvement in cash flows has risen for the third consecutive quarter in 2025 to its highest level since 2022. While private sector investment has moderated, total business credit demand remains strong and is expected to grow by 7.2% in 2026. New Zealand economy slows amid policy support New Zealand’s economic recovery has been slower than anticipated, despite the Reserve Bank of New Zealand delivering 300 basis points of monetary easing since mid 2024 to stimulate the economy. Export activity has been dampened by global trade uncertainty and broad-based industry weakness. Household spending remains constrained by elevated living costs, labour market softness and the delayed impact of rate cuts due to the prevalence of fixed rate mortgages. While the recovery in economic activity has been delayed, lower interest rates has supported housing demand with credit growth expected to rise to 5.7% in 2025 and 6.3% in 2026. Monetary easing supports a balanced global outlook The global economic backdrop remains mixed. Inflation is broadly within target ranges across most advanced economies, enabling a gradual easing in monetary policy. This has supported modest global growth, with GDP expected to expand by around 3% in both 2025 and 2026. However, risks to the outlook remain elevated. These include ongoing global trade tensions, geopolitical uncertainties and lingering inflationary pressures, all of which continue to weigh on sentiment and investment. 1.

146 WESTPAC GROUP 2025 ANNUAL REPORT OUR STRATEGY Our refreshed strategy outlines five priorities that will help us achieve our ambition: To be our customers' number one bank and partner through life. PERFORMANCE CUSTOMER TRANSFORMATION PEOPLE RISK For customers, we are focused on delivering a seamless banking experience across every channel; in branch, digitally and by phone. A whole-of-bank approach seeks to bring our people together, to offer the full breadth of our products with more timely, personalised service. This, combined with digital innovation and investment in platforms such as BizEdge, Westpac One and Digital Banker, supports our ambition to lead in Consumer and Business Net Promoter Score (NPS1 ) and for Institutional, to achieve the number one position in the Relationship Strength Index (RSI2 ). For our people, we recognise we must provide a market-leading employee proposition to deliver superior customer experiences. To sustain high engagement and attract and retain the best talent, we’re committed to equipping our people with future-ready skills and creating a more rewarding, supportive work environment. Proactive risk management is central to Westpac's strength and resilience. Through the completion of the CORE program, we’ve taken steps to significantly transform our risk culture, governance and management practices. Sustaining and continuously strengthening these improvements across Westpac remains a priority. Transformation is critical to our future success. Our cornerstone program UNITE aims to unlock long-term value simplifying products, processes and systems to help deliver improved customer experience, make work easier for our people and reduce operating costs. Complementing UNITE are two flagship digital innovations, BizEdge and Westpac One. We measure performance by market position and return on tangible equity (ROTE). We are pursuing growth that delivers sustainable returns, focusing on areas where we can differentiate Westpac's customer offering. Maintaining cost discipline remains important, with simplification through UNITE expected to play a key role in reducing our cost base and closing our cost to income gap relative to peers. 1.

148 WESTPAC GROUP 2025 ANNUAL REPORT Top and emerging risks We regularly assess our operating environment to identify changes, emerging risks and opportunities. The factors1 below may affect Westpac’s ability to create value over the short, medium or long term. For further information, refer to Risk Management (pages 180-187) and 2025 Risk Factors. Geopolitical risk Uncertainty around world trade policy remains a key global risk, with potential impacts on trade, supply chains and investor confidence. Combined with broader geopolitical tensions and ongoing global conflicts, these factors may influence export demand, commodity prices and inflation not only in Australia and New Zealand but also in other markets where Westpac operates. Our response Credit markets where Westpac operates remain resilient, supported by strong domestic fundamentals and a stable financial system. Westpac’s capital position and balance sheet remain strong. We will continue to monitor developments closely and, as part of our origination process, assess all known risks at the time of origination to help manage risk whilst meeting customer needs. Refer to Credit Risk and Market Risk (pages 182-187). Technology risk Technology remains a key priority for Westpac, enhancing our ability to create long term value for stakeholders. The adoption of AI is progressing rapidly within the financial services industry. AI will have positive impacts such as improving operational efficiency however it is important to ensure its safe and responsible use. Our response Westpac continues to invest in technology and has introduced Responsible AI Principles and an AI Risk Management Standard, which is designed to support effective management of AI-related risks. Its implementation is supported by awareness campaigns and training programs aimed at strengthening overall risk management capabilities. Refer to Strategic Risk (pages 182-187). Cyber risk The cyber threat landscape poses a risk to financial stability by targeting critical infrastructure, undermining public trust, and exposing institutions to operational, legal and reputational harm. High levels of interconnectedness and dependence on third party suppliers, combined with rapid technological change, such as the adoption of AI and a rise in international threats, are contributing to increased cyber risk. Our response We continually assess and strengthen our cyber resilience to defend against increasingly sophisticated and capable threat actors. We also actively work with government, regulators, and industry stakeholders to bolster Australia’s cyber defences, including through threat intelligence sharing and support for cyber security reforms. Refer to Cyber Risk and Operational Risk (pages 182-187). Culture and capability Managing and responding to expectations from customers, regulators and the community requires strong risk management. Poor conduct, negative customer experience, or failing to adequately respond to risks such as scams can impact our integrity and the trust of our stakeholders. Our response Risk is one of our top five strategic priorities. We regularly assess our risk culture and have strengthened our risk management and governance through the successful delivery of the CORE program. We aim to build on these improvements by ensuring our people and processes are aligned to deliver our purpose and strategy. Refer to Reputational and Sustainability Risk and Compliance and Conduct Risk (pages 182-187). Competition Competition in the lending market remains elevated, driven by financial institutions and non-bank lenders seeking to expand market share. At the same time the increasing share of brokers is placing pressure on returns. The potential for regulatory arbitrage between bank and non-bank lenders is reshaping the lending landscape, influencing how lenders compete across risk, capital and service delivery. Our response We actively manage the impact of external changes that may affect our ability to deliver on our strategy. Continued simplification, innovation, and investment in technology are critical to delivering more consistent high quality customer service, products and value at scale and maintaining operational resilience in a competitive environment. Refer to Credit Risk and Strategic Risk (pages 182-187). 1. Not exhaustive. Refer to Risk Management (pages 180-187) for full table of material risk categories.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 149 Our approach to sustainability At Westpac, sustainability is about creating long-term value for our stakeholders. By identifying what matters most to them, we aim to ensure their priorities and concerns are considered in our decision-making, helping to strengthen our long-term value. Our approach is anchored in our Sustainability Strategy which aligns with our corporate strategy and refreshed purpose. It outlines how we will embed sustainability across the strategic pillars and the focus areas of climate transition, housing affordability and regional prosperity. The Chief Sustainability Officer (CSO) reports directly to the CEO and is responsible for developing and overseeing the Sustainability Strategy and a suite of supporting policies, positions and plans. Progress on how we manage, implement and deliver our strategy, frameworks and initiatives is regularly reviewed through Board and executive-level governance forums. External engagement with our stakeholders also plays an important role by bringing wider perspectives to inform our approach. This supports our decision making and the annual materiality assessment. Our Sustainability Strategy is available on our website. Sustainability-related disclosures Westpac’s sustainability reporting aims to provide stakeholders with insights into performance over time and against key benchmarks. It covers progress on climate action, natural capital, human rights and support for Indigenous Australians, providing details of our impact and connection with global standards. This includes the Sustainability Report and Sustainability Index and Datasheet, available on our website. Sustainability Report The 2025 Sustainability Report details Westpac’s strategy, targets, and approach for managing climate-related risks and opportunities. The report also provides updates on our efforts to reduce emissions, assist customers in their transition and improve climate resilience. Replacing Westpac’s previous Climate Report, the document prepares us for mandatory climate reporting from next year. Climate Transition Plan This year marked the end of the 2023-2025 Climate Change Position Statement and Action Plan. This has been replaced by a Climate Transition Plan (CTP). Built on stakeholder feedback, the CTP outlines our targets and approach to achieving our climate ambition of becoming a net-zero, climate resilient bank. Our sustainability disclosures can be found on the website. Material sustainability topics Our method for determining material topics is guided by the Global Reporting Initiative (GRI) Universal Standards. We report on material topics throughout this report.

To support this, we have adopted a whole-of-bank approach to help deliver personalised, seamless and secure banking experiences. We have also expanded our presence with more bankers and new regional service centres. Our banking apps, extensive branch network, virtual teams and dedicated Customer Care reflect our commitment to meeting customers where they prefer ‒ digitally, in-person and by phone. Stronger relationships will support more customers choosing us as their main financial institution. Refer to Creating value for customers (pages 160-165) for more.

The UNITE program aims to unlock long-term value by addressing structural legacy issues that have hindered our progress for more than a decade. It is focused on simplifying products, processes and systems to help deliver improved customer experience, make work easier for our people and reduce operating costs. Other strategic imperatives that remain critical to our transformation agenda include – WestpacOne and BizEdge. Refer to Transformation (page 178) for more.

Australian household deposits growth of 1.0x APRA system demonstrates the health of our franchise. Business deposits increased 6% primarily in transaction balances driven by new account openings and retention. Growth in Australian housing loans, excluding RAMS1 , of 5%, or 0.8x APRA housing system, was mainly in owner occupied mortgages. The proportion of investor lending increased over the year reflecting our targeted strategy. Total Australian housing loans growth was 3%. In Business, lending was up 15%. This included strong loan growth in our target sectors of agriculture, health and professional services performing well. Institutional lending growth of 17% reflected activity in the infrastructure, resources, energy and property sectors. New Zealand deposits grew by 2% with solid growth of 0.3x RBNZ system in household deposits partly offset by a strategic decrease in Institutional term deposits which have a lower liquidity value compared to other sources of funding.

Technology expenses were up 13% due to higher costs related to the UNITE program, an increase in software amortisation related to projects completed in prior years and higher software maintenance and licensing costs. Other Expenses decreased by 3%a due to lower professional and servicing costs and higher costs in the prior year from the closure of RAMS, partly offset by higher litigation and remediation costs, and advertising spend.

158 WESTPAC GROUP 2025 ANNUAL REPORT Credit quality sound, strong balance sheet Credit quality improved and we maintained a strong financial position with capital, funding and liquidity all above regulatory minimums. Credit quality Credit impairment charges represented 5 basis points of average gross loans compared to 7 basis points in the prior year. The low level of impairment charges was driven by our prudent lending practices and customer resilience across both households and businesses. The improvement in credit quality metrics reflects a more favourable operating environment and the reduction in household cost of living pressures as inflation has eased and interest rates have declined in both Australia and New Zealand. We remain appropriately provisioned with credit impairment provisions of $4,987 million, $1.9 billion above the expected losses of our base case economic scenario. Over the year provisions decreased by 2% with an overall improvement in portfolio credit quality more than offsetting an increase in the downside scenario weight and higher overlays. STRESSED EXPOSURES AS A % OF TCE 1.45 1.28 Sep-24 Sep-25 Capital The CET1 capital ratio of 12.5% is above our target ratio of 11.25% in normal operating conditions. This equates to $3.1 billion of capital above the target after payment of the second half 2025 dividend. The CET1 capital ratio increased 4 basis points as net profit was largely offset by the payment of dividends and increases in Risk Weighted Assets (RWA). CET1 CAPITAL RATIO 12.5 12.5 18.3 18.3 APRA basis Internationally comparable Sep-24 Sep-25 Funding and liquidity The September quarterly average liquidity coverage ratio (LCR) and the net stable funding ratio (NSFR) were both above regulatory minimums. The deposit to loan ratio increased slightly, with deposit growth broadly funding loan growth during the year. The Group raised $28 billion of new long term wholesale funding. Long term wholesale funding needs in 2025 were lower compared to recent financial years, reflecting growth in household deposits and lower wholesale funding maturities. The bank maintained stable short term wholesale funding balances, with movement mainly driven by changes in FX rates. Long term wholesale funding where the residual maturity is less than one year increased. LCR AND NSFR (%) 133 112 137 113 LCR NSFR 84.9% Deposit to loan ratio, up 137bps on Sep-24

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 159 Segment performance Our operating segments including Group Businesses contribute to Group performance. For descriptions of Consumer, Business & Wealth, Institutional and New Zealand refer to page 147. Group Businesses includes Treasury, Enterprise services and other costs not directly attributable to segments. In 2025, the composition of our segments was revised to improve operational alignment. Prior year comparatives have not been restated. The key changes included: • The merchants services business was transferred from Business & Wealth to Institutional given strategic alignment with management of payments infrastructure; • The contribution from the auto finance portfolio which was sold in March 2025 was transferred from Business & Wealth to Group Businesses; and • Centralisation of Finance and Human Resources into Group Businesses. The impact of Notable Items on net profit, income and expenses have been excluded from the Segment Performance section. These measures are used by Westpac for management reporting and is consistent with the disclosure in Note 2. Consumer Net profit increased 4% to $2,282 million and pre-provision profit increased 4% to $3,492 million. Segment composition changes had a minimal impact, with pre-provision profit also rising 3%. Operating income rising 4% and operating expenses increasing 4%. The increase in operating income reflected 3 basis points of net interest margin expansion with disciplined growth in mortgages and strong deposit growth. Expense growth was driven by a step up in UNITE spend and inflationary pressures, partly offset by benefits from productivity initiatives. Impairment charges to average loans were 4 basis points, compared to 5 basis points in the prior year. The decrease reflects the improvement in credit quality metrics. 33% Contribution to Group net profit Business & Wealth Net profit decreased 7% to $2,186 million and pre-provision profit fell 4% to $3,383 million. Excluding the impact of segment composition changes, pre-provision profit fell 1% with a 3% increase in operating income more than offset by a 10% increase in operating expenses. Operating income reflected strong growth in lending balances, partly offset by a lower net interest margin, while operating expenses increased due to the step up in UNITE spend and investment in front line bankers. Impairment charges to average loans were 23 basis points, compared to 14 basis points in the prior year. The increase reflects an increase in the downside scenario weight and higher overlays, while credit quality metrics improved. 31% Contribution to Group net profit Institutional Net profit increased 15% to $1,575 million and pre-provision profit increased 6% to $2,161 million. Excluding the impact of segment composition changes, pre-provision profit rose 2%, with a 5% rise in operating income more than offsetting an 11% increase in operating expenses. The growth in operating income reflects lending growth and higher earnings on capital. The 11% increase in operating expenses was driven by increased investment spend, including the step up of UNITE and higher software amortisation, in addition to an increase in bankers to support growth. The impairment benefit of $1 million, compared to a 13 basis point charge of $120 million in the prior year. The decrease reflects the improvement in credit quality metrics. 23% Contribution to Group net profit New Zealand Net profit increased 13% to NZ$1,197 million and pre-provision profit increased 8% to NZ$1,618 million, reflecting an 8% increase in operating income which more than offset a 7% increase in operating expenses. Operating income reflected growth in lending and a higher net interest margin, while operating expenses were driven by higher staff expenses, third party vendor costs, software amortisation and higher investment spend. The impairment benefit was 4 basis points of average loans, compared to a charge of 3 basis points in the prior year. The decrease reflects the improvement in credit quality metrics. 16% Contribution to Group net profit Group Businesses Net loss of $161 million compared to a net profit of $227 million. Excluding the impact of segment composition changes pre-provision profit also decreased 92%, reflecting an 11% decrease in operating income and a 34% increase in operating expenses. The decrease in operating income reflects lower income on surplus capital, while operating expense growth reflects the restructuring charge as part of the targeted productivity initiates through the Fit for Growth program.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 161 Australia’s best banking app Westpac’s banking app continues to set the benchmark for digital banking in Australia, ranked #1 for a third consecutive year1 . To recognise and reward customer loyalty, we launched a dedicated Westpac Rewards hub. This is designed to make it easy for customers to find, track and redeem rewards across multiple channels. Customers received more than $159 million in rewards value across multiple loyalty channels, including our market first partnerships with ShopBack and Woolworths Everyday Rewards. Westpac customers can access essential everyday banking features alongside valuable money management tools, such as Cashflow and Smart Search, which support decision making and financial goal setting. The Savings Finder feature analyses annual spending on subscriptions and recurring expenses to identify potential savings opportunities, enhancing customer value and engagement. Across all digital channels, an average of 1.1 million customers each month use money management tools to budget, track spending and understand their financial position. To support safe digital banking, we expanded our market-leading security features designed to protect customers from scams and fraud. Westpac SafeCall and SafeBlock are our latest Australian-first innovations. Refer to Innovating to protect customers (page 163) for more information on our suite of digital innovations. Enhancing financial literacy We are committed to improving the financial wellbeing of customers and the community through free financial education initiatives. We have a long-standing partnership with Year13, an online financial literacy platform designed for young Australians. The program offers engaging and practical content to build lasting financial habits. We connect with this important demographic through relatable examples and interactive content, such as videos, quizzes and self-paced modules, delivered via the social channels they use most. We also invest in digital tools and youth engagement programs. Our banking app’s Pocket Money and Chores feature supports parents in teaching children about saving and spending in a fun, engaging way. An online Financial Literacy Hub offers tailored learning resources for kids, teens and school leavers. In a new collaboration with an online influencer, we produced a 12-part series called Financial Fresh Start, focused on building good financial habits and awareness, along with steps customers can take with support from their bank. In New Zealand, 12,206 people participated in Managing Your Money workshops, representing a 9% increase on the previous year. These were delivered alongside targeted seminars through our partnerships with Chambers of Commerce. In the Pacific, we deliver culturally relevant financial education in Fiji and Papua New Guinea, reaching thousands of people and small business owners through webinars and workshops such as Financial Basics for My Business. 1.

162 WESTPAC GROUP 2025 ANNUAL REPORT CREATING VALUE FOR CUSTOMERS Delivering service excellence Exceptional customer experiences depend on many factors, including ensuring our people, systems and processes work together seamlessly to deliver timely, consistent and personalised service. We are focusing on connecting the full breadth of our capabilities, across every operating segment and customer touchpoint, to bring the whole bank to customers. This integrated approach aims to remove customer pain points, strengthen advocacy and build deeper relationships over time. Through mapping, measuring and improving more than 15 critical customer journeys across our Australian operations, we are helping teams to walk in customers’ shoes and drive cross-functional collaboration. This also provides us with better insights to help customers achieve their financial goals. While the program is a recent initiative, early feedback indicates customers are engaging with a broader range of our products and services. In addition, we are extending the rollout of the single banker platform, Digital Banker, to support approximately 20,000 employees across Consumer and Business. This portal captures customer interactions and needs, providing better insights and experiences for customers and bankers. Prioritising safety in products and services We were proud to develop Australia’s first Safety by Design Toolkit for financial institutions, placing customer safety and rights at the centre of product and service design. In collaboration with the Australian Banking Association, the toolkit includes customer vulnerability personas, lived experience videos and mandatory eLearning for product managers. It has been shared with peer organisations to help support more Australians, regardless of who they bank with. Westpac remains committed to sector-wide reform, advocating for Safety by Design across banking and beyond, so customer safety is built-in from the start. Providing support in tough times We understand that anyone can fall on tough times so our Assist team provide a range of tailored solutions to help customers regain financial stability. This can include short-term options such as payment pauses and reduced repayments, as well as longer-term assistance plans designed to support recovery. We also connect customers with our wider network of external partners, extending support into wellbeing and financial empowerment. By collaborating with respected organisations, we hope to help strengthen families and communities, break cycles of disadvantage and build lasting financial confidence. We supported customers with 46,485 tailored hardship assistance and disaster relief packages, giving customers financial reprieve and the chance to get back on track. At the end of the financial year, 10,870 accounts remained in hardship. Through UNITE's collections migration, we are consolidating multiple legacy systems into a single platform to support customers and reduce complexity. It includes new tools to help teams respond to customers in hardship with greater consistency and care. Resolving complaints Complaints are a second chance for us to make things right for customers. Our monthly average resolution time is stable, with 94% of complaints resolved without need for escalation. Our Customer Advocate also provides advice, while recommending policy changes and supporting vulnerable customers. Listening to feedback helps us to continuously improve our products and services. Importantly, we are using complaints as a key input into the customer journeys initiative, ensuring we have a genuine view of pain points and the end to end customer experience. For example, through UNITE, we introduced the option for eligible Westpac home loan customers to set up multiple offset accounts with no additional fee – providing more choice and control in how they manage their finances. More than 35,000 offset accounts have been set up since February. Listening to customers We proactively and continuously seek customer feedback, using insights from Net Promoter Score (NPS)1 surveys, complaints and direct feedback which helps us to measure progress and identify areas for improvement. To be Australia’s best bank, we recognise there is more work needed to lift customer and brand advocacy. In Consumer, NPS1 improved during the year, despite intense competition. We are currently ranked equal second in Consumer NPS1 . In Business, we hold an NPS1 score of minus one and have established clear leadership in the SME and Commercial sub-segments. We are prioritising improvements in our service offering for small business customers, recognising the importance of this segment to our Business & Wealth strategy. For our Institutional customers, we aim to be their bank of choice, supporting all their banking needs through strong relationships and comprehensive solutions. Our Relationship Strength Index (RSI2 ) rose by 19 points, marking our highest score in a decade. While we are currently in equal third position, our focus on deepening relationships positions us well for continued growth in this segment. 1.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 163 Innovating to protect customers We continue to play a critical role in safeguarding customers from the growing risk of cyber threats and financial crime. Through digital innovation, AI and a multi-layered security approach, we continuously enhance our real-time protections. We were the first Australian bank to offer the benefits of SaferPay and more recently SafeCall, which verifies Westpac calls for customers directly through the app. SafeBlock was also launched along with Confirmation of Payee, which builds on our existing Verify technology and has been adopted industry-wide. Our suite of digital innovations helped to further reduce reported customer losses by 21% and prevented $360 million in potential losses. This outcome reflects our commitment to supporting customers’ financial wellbeing by helping them stay safe in a complex digital environment. WESTPAC SAFECALL Customers receive calls via the banking app that are Westpac branded, verified by Optus and show a reason for the call to remove uncertainty about who is contacting them. WESTPAC SAFEBLOCK Allows customers to instantly lock their eligible accounts and cards, including blocking outgoing payments, transfers, and purchases, if they suspect fraud or a scam, while allowing deposits and scheduled payments to continue. CONFIRMATION OF PAYEE Alerts customers when there is a potential account name mismatch by checking if the account name entered by a payer matches the details held by the receiving bank, further reducing the risk of misdirected payments. Educating and empowering customers Prevention and detection go hand in hand, which is why we work proactively to keep customers informed about emerging threats. Our Cyber Response Playbook and Scam Spot video series inform customers and the community on new tactics. To empower customers, our app offers additional security tools including the Security Wellbeing Check, Westpac Protect SMS Code, Dynamic CVC and biometric authentication to help customers safeguard their accounts. Providing timely support Fraud and scams can have devastating and widespread impacts. While we make every effort to recover funds sent to scammers, this is unfortunately not always possible. Our dedicated Fraud and Scams team, supported by AI and automation, detect suspicious patterns and risks to support customers in critical moments. We launched a new feature in the app that enables customers to report scams, fraud, or mistaken payments quickly and securely. Our Online Banking Security Guarantee 1 and Fraud Money Back Guarantee 1 continue to offer peace of mind in certain situations. Advocating for change We continue to advocate for a whole-of-ecosystem approach to scam prevention. We supported the development of the new Scams Prevention Framework Act 2025, which requires all parties, including banks, telcos, and social media platforms, to take preventative steps to protect consumers. We continue to work closely with industry peers to inform policy and regulatory settings under this new legislation. SAFERPAY PROTECTS RETIREES FROM INVESTMENT SCAM An elderly couple attempted to transfer $500,000 to what they believed was a legitimate high-interest term deposit. The offer came from scammers posing as financial advisers, complete with official-looking documentation. Their online transactions triggered real-time SaferPay prompts that exposed inconsistencies. Our team intervened immediately, preventing any financial loss. The customers were incredibly relieved that SaferPay had stepped in to protect them. 1.

164 WESTPAC GROUP 2025 ANNUAL REPORT CREATING VALUE FOR CUSTOMERS Maintaining community presence We recognise that many customers prefer face-to-face support, particularly when making important financial decisions. We provide trusted support across 621 branches which includes 125 co-located branches. This represents the second-largest branch network in Australia, with more than 37% of these located in regional areas. We have the largest fee-free ATM network in the country. Complementing our branch network is a Virtual Banking team, providing secure, expert support via phone, video, and chat. From early 2026, customers will also have access to a new Book a Banker tool, facilitating appointments with lenders when it suits them. Our long-standing partnership with Australia Post offers another face-to-face banking option through 3,300 Bank@Post outlets nationwide. Supporting Indigenous customers Westpac supports Indigenous customers across multiple channels including a dedicated Indigenous Call Centre with translators to support Indigenous languages. On-the-ground teams in remote areas of every State and Territory work in partnership with community groups to help empower Indigenous customers and support their banking needs. Promoting regional prosperity Regional Australia plays a vital role in the nation’s success and we believe unlocking its full potential is key to driving sustainable economic growth. This is a focus of our refreshed sustainability strategy, which aims to support regional business growth, local employment and positive community and environmental outcomes. In response to the unique needs of regional communities, we listened to customer and community feedback by reflecting on how we could improve our service offering. We have introduced a new regional banking model through integrated service centres that bring retail and business banking under one roof. This model delivers a more personalised and comprehensive banking experience, which helps to build trust and stronger, more enduring relationships over time. We committed to three service centres in new locations, with more planned in the future. This was bolstered by our growing business banking and agribusiness team with deep industry expertise. Our pledge to keep regional branches open has been extended to mid-2027, providing greater certainty for customers, employees and communities. Importantly, our focus isn’t limited to financial support and services. A resilient and stronger future for regional and rural Australia also relies on unlocking potential through innovation. Our agri-tech investments combined with agriculture-related sponsorships, scholarships and partnerships are fostering the next generation of farmers, helping them to solve critical industry issues. Faster lending decisions Following our operational improvements last year to reduce time to decision for home loan customers, we’ve continued to simplify mortgages end-to-end by streamlining policies and processes and accelerating automation. We have also improved our home loan same-day settlement performance, now ranked number one among Australia’s major banks1 . This supports our strategic focus on improving service and fostering deeper customer relationships. We halved documentation requirements for self-employed applicants through the introduction of a one-year income assessment option. This is helping to make the home-buying journey simpler for self-employed Australians. In addition, we commenced the roll-out of a simplified digital experience for personal loans. The initiative aims to reduce manual processing and improve turnaround times for both new and existing customers.

Our new Access & Inclusion Plan 2025-2028 outlines how we’ll continue to enhance banking so every customer can engage in a way that suits their needs. We are committed to meeting diverse accessibility needs by, for example: • Providing space for assisted devices and personal support in branches; • Promoting awareness of assistive technologies such as screen readers, chatbots and text-to-speech functionality; • Supporting customers who wear a Hidden Disabilities Sunflower accessory; • Offering multiple communication options including interpreters, translation services, AUSLAN and the National Relay Service; • Delivering cultural awareness training for staff; and • Providing training and resources to support non-binary and gender-affirming customers. Responsible marketing and advertising We regularly review and enhance our policies, procedures, and processes to ensure they consistently support positive customer outcomes. This commitment also applies to how we market our products and services towards suitable customers, as detailed in our Responsible Marketing and Advertising policy on our website. Safeguarding data and privacy Earning and maintaining customer trust is essential to our long-term success. All employees complete mandatory annual training on data privacy and cybersecurity. Our Privacy Statement outlines how we protect personal information, while our Cybersecurity Statement details our alignment with global and ISO standards. We continue to invest in secure-by-design policies and infrastructure to meet evolving expectations and requirements. Supporting female entrepreneurs We have doubled our commitment to supporting women in business, increasing this to $1 billion to help more women overcome the challenges of starting or growing a business. Since launching the initiative two years ago, we have helped more than 1,800 women in a range of industries, including retail, healthcare, creative services and hospitality. Assisting vulnerable customers We continue to strengthen protections for vulnerable customers through specialist support teams and proactive monitoring of payment descriptions and power of attorney accounts to identify potential misuse. We also offer self-serve product features such as gambling blocks and parental controls. To respond to threats and improve safeguards, we work closely with community organisations and law enforcement. Customers with eligible government concession cards can also open a basic bank account, which has no monthly account keeping or overdrawn fees. Our teams are trained and equipped to identify and support vulnerable customers, and to connect them with external partners where additional assistance is needed.

Receiving the ‘Employer of Choice’ award for large organisations at the Australian HR Awards recognises the progress we’ve made in making Westpac a great place to work. We are building on this momentum under the guidance of a new Chief People Officer, while executing UNITE to help make our working environment simpler and more rewarding for our people. With a renewed Purpose, our values were updated in July to three clear, actionable commitments: Always deliver, safely; Make an impact; and Own it. We are embedding these into processes to align expectations and shape a service mindset. We’re actively supporting our leaders to help shape our culture. One way we do this is by embedding skill boost sessions into weekly team rhythms. These activities encourage open conversations around positive risk behaviours such as speaking up, admitting mistakes and taking initiative. In June 2025, our final Voice+ survey including the Organisational Health Index (OHI) was completed. The score remained at 80, reinforcing Westpac's position in the top quartile of organisations globally. This reflects our progress in recent years to reset culture and strengthen risk practices through the CORE program, which is now complete. For more detail, refer to page 181. Listening and acting on feedback Feedback is essential to building a culture of trust and continuous improvement. It ensures people feel heard, empowered to act, and aligned to our purpose. To capture more dynamic employee insights and drive further improvement, we’ve transitioned from Voice+ to a new Amplify platform. Amplify enables leaders at all levels to act on team feedback, strengthening engagement and risk management. Insights help leaders and teams agree on priorities and turn feedback into measurable change, supporting our goal of becoming the best place to work. We also engaged with our people to understand how they want to use AI to work more effectively and provide better service to customers. Our inaugural CEO-sponsored AI Shark Tank program drew significant engagement, with 3,600 employees participating and 1,200 ideas submitted. It highlighted a keen interest in embracing AI across the company. 10 standout opportunities were selected by Executives for implementation. We also responded to employee feedback through our continuous improvement platform Ignite, which uncovered valuable ways to boost productivity, improve customer experience and reduce risk. In addition, leaders have regular conversations with their team members to provide performance and development feedback to engage and motivate our people. RECOGNISING GREAT OUTCOMES The recognition of our people is embedded in our culture. We have formal mechanisms in place to encourage and recognise high performance, including those linked to excellent risk outcomes. The Great Employee Moments (GEM) platform captured 190,000 recognition moments, which informed our award winners. The annual CEO Awards (pictured) at the end of each calendar year are the pinnacle of our recognition framework, celebrating individuals and teams who exemplify excellence, leadership and impact across the business. Each quarter, the Board directly recognise individuals who demonstrate positive risk outcomes, exceptional courage, innovation or leadership beyond the expectations of their role.

168 WESTPAC GROUP 2025 ANNUAL REPORT CREATING VALUE FOR OUR PEOPLE Attracting and retaining talent Attracting and retaining talent sparks innovation and builds a workforce that reflects the diversity and capability needed to deliver great results. We are advancing this through several targeted strategies. Onboarding and Orientation: We introduced a refreshed onboarding and orientation program for new talent, featuring customer immersion sessions, hands-on activities and engagement with our Executive team. Graduate Program: We rank in the top ten of Australian Financial Review 'Top Grad Employers for 2025’ for our award-winning graduate program. We hired 135 graduates, comprising 58% female and 52% from a STEM background. Licensed to recruit: A new Licenced to Recruit training program is strengthening the capability of People Leaders making hiring decisions. To date, more than 1,500 leaders have completed face-to-face training across Australia. Internal talent mobility: We saw a second consecutive year of improvement in internal talent mobility, which is up 5% from FY23. This was driven by the launch of a new Internal Careers site with enhanced employee tools and the introduction of the Westpac Talent Community. We continue to support redeployed employees through job-matching tools and reporting dashboards that help identify opportunities and track outcomes. Diverse hiring: We maintained our commitment to diverse hiring, with 49% overall female representation, even as recruitment efforts pivoted towards male dominated technology-focused roles. Notably, MobTech welcomed 11 new Indigenous cadets. Our dedicated female talent initiative, EmPOWERUp, creates a pathway for women to reignite their careers after an extended leave break. It continues to build a strong candidate pool across all levels and disciplines, with approximately 1,300 women engaged to date. Developing leadership capability People leaders are critical to our success. They shape our culture, drive performance and role model the behaviours that enable teams to thrive. We have three signature leadership programs to develop leaders at all levels. The Horizon program for executive leaders resumed with its fourth cohort. This is part of a broader leadership development strategy aimed at strengthening executive capability and driving cultural transformation. To further align broader leadership behaviours with performance outcomes, we launched the Westpac Leadership Qualities framework, which will be reinforced in a new Executive Leadership Group1 Scorecard from FY26. We introduced two new leadership programs designed to strengthen capability for more than 4,000 employees through to FY27. Elevate supports our senior leadership cohort, while LEAD is tailored for mid-level and emerging leaders. These programs focus on executive coaching and developing adaptive leadership, high-performance and an enterprise mindset. We are committed to supporting the development and progression of women at Westpac. This includes accelerating the impact of programs such as Illuminate, our female sponsorship initiative and Step-Up, a new career development program. Refer to page 169 for more information. Investing in skills for the future Equipping our people with future skills and capabilities is at the heart of our learning and talent strategy. It encompasses both mandatory and optional training, leadership development as well as addressing capability gaps across the organisation. Mandatory training is completed by all employees and covers compliance, privacy and data protection, risk awareness, identifying hazards and conflicts of interest. We expanded optional learning in emerging areas such as AI, sustainability and cybersecurity. More than 10,000 employees completed training in generative AI through our Microsoft 365 Copilot rollout. See Data, Digital and AI on page 179 for more information. In Business & Wealth, we relaunched The Business Performance Academy, offering targeted training to 3,000 employees to build confidence and advance their careers. This is complemented by learning programs designed to build confidence in discussing sustainability matters with customers. A new self-directed leadership program, IMPROVE, was developed by the NeuroLeadership Institute and is designed to enhance feedback skills for leaders using contemporary research. Our people also accessed degree programs and certification training, supported by paid study leave. 1. Includes approximately 190 senior leaders, including Group Executive direct reports (General Managers (GM) and Chief of Staffs) and key GM1 roles.

One way we advance inclusion is through 10 employee advocacy groups, connecting more than 11,000 people who champion diversity across areas such as gender, disability, LGBTQ+ communities and cultural backgrounds. We also refreshed the Access and Inclusion Plan, marking a 25 year commitment. We have a zero-tolerance approach to sexual harassment and related unlawful conduct, encouraging respectful behaviour and accountability. We encourage our people to be upstanders and speak up against inappropriate behaviours. Our policy includes training, dedicated reporting channels, a no-bystander rule and investigation and support processes. We also delivered training to the Board and Executive Team on their positive duty obligations under recent legislative reforms. We continue to champion gender diversity, with women holding 49% of senior leadership roles. To build on this, we aim to achieve a 40:40:20 balance at all levels by FY30, with 40% women, 40% men and 20% of any gender. In a submission to the Workplace Gender Equality Agency (WGEA), we reported an overall average gender pay difference of 2% based on similar roles or levels. The median gender pay gap reduced by 1.2% to 28.1% and this figure is heavily influenced by the composition of our workforce, with many women employed in contact centres, operations and branches. Our new gender diversity target is designed to help address this. The Illuminate program supported 82 aspiring female leaders through GM sponsorship, with more than 35% advancing to new or expanded roles. As the first bank to join Diversity Council Australia’s RISE Project, we are supporting 20 women from diverse racial and cultural backgrounds to advance their leadership careers. We are investing in specialised programs to recruit, retain and develop Aboriginal and Torres Strait Islander people, supported by a dedicated First Nations Engagement Manager. Refer to page 173 for more information. Prioritising health, safety and wellbeing We recognise health, safety and wellbeing play a vital role in how our people show up at work. We are committed to fostering a safe, secure and supportive environment, focused on protecting people from physical and psychological harm, supporting mental health and providing a respectful and inclusive workplace. The mental health strategy is shaped by our Chief Mental Health Officer. Reviews of each segment were conducted, which helped develop targeted action plans to address psycho-social risks and better understand the factors influencing wellbeing at work. This was complemented by mental health training in partnership with the Black Dog Institute. For our Retail bankers' safety, we delivered face to face de-escalation training to 157 branches and psychological first aid training to 375 Consumer leaders. Wellbeing remains a core part of our employee value proposition. We launched a new mobile Wellbeing App with personalised content and holistic wellbeing assessments to encourage healthy living. This complements our other health initiatives including fitness incentives, access to 24/7 counselling and free flu vaccinations. Flexible working arrangements support a healthy work-life balance. In addition, our latest EVP introduced new leave benefits including doubling Culture, Lifestyle and Wellbeing Leave to four days, increasing Compassionate Leave from three to five days per occasion, as well as five days leave to support employees to attend appointments related to fertility treatment, surrogacy, adoption and foster care. We also make superannuation payments during unpaid parental leave, rather than waiting until employees return to work. We offer market-leading banking benefits for employees, contractors and their families. Eligible employees receive a Salary Continuance Insurance benefit, also known as Income Protection Insurance, in case of illness and injury. In addition, a MyDiscounts employee portal continues to offer exclusive offers and discounts from leading brands. BUILDING STRONGER CUSTOMER CONNECTIONS We believe it’s essential for our people to understand how their roles contribute to better customer outcomes. We created opportunities for all teams, including business functions like risk, legal and compliance, to connect with customer experiences supported by Customer Obsession Learning and Service Mindset sessions attended by 1,000 people. Additionally, 2,500 people completed Immersion training and 600 participated in Customer Journey Bootcamps. We're building a workplace where everyone feels empowered to deliver great customer outcomes.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 171 Since establishing our first charity in 1879, we have remained committed to building stronger, more inclusive communities. Our approach continues to evolve and is guided by where we can deliver the greatest impact for customers and their communities. Westpac offers a range of community investment initiatives that encourage employees to contribute their time, skills and experience to causes they are passionate about. These initiatives also help to foster trust and deeper connections with the communities we serve. Australian employees receive one day of paid volunteer leave each year. This offers valuable opportunities for personal and professional development while delivering meaningful benefits to the community. Our people contributed 65,538 hours to initiatives ranging from volunteer firefighting to mentoring social enterprises. In addition, 140 people also participated in Jawun secondments, the Community Ambassador and Westpac Board Observer programs. Through our workplace giving initiative, Westpac matched $1.6 million in employee donations to 200 charities. New chapter, stronger commitment We spent time assessing how to maximise our impact for current and future generations. To align with Australia’s national education and productivity goals, from 2026 the Westpac and Regional Foundations and our community initiatives will unite next year behind a single, critical objective: improving literacy and numeracy outcomes for children facing disadvantage. We believe every child should have the tools to unlock their potential, regardless of background or the challenges they face. Refer to our 2025 Foundations Impact Report for more information. Westpac Foundation1 The Westpac Foundation awarded $2.2 million to 8 new social enterprise partners to support job creation. It has positively impacted hundreds of communities in the past 20 years by providing meaningful employment opportunities for people facing barriers to work, achieving its ambitious goal to create 10,000 jobs by 2024. Regional Foundations1 The Regional Foundations have helped to lay the groundwork for our focus on education, with 40% of grants since 2023 supporting inclusive education. They awarded $3.3 million this year to programs that boost educational and wellbeing outcomes for young people facing disadvantage (refer to case study). Westpac Scholars Trust1 The Trust's landmark pledge is to award 100 scholarships a year, forever. The Trust awarded $5.1 million to scholars this year, bringing its collective impact to $50 million since 2015. Te Waiu O Aotearoa Trust2 The Trust awarded $5,000 scholarships to eight Māori recipients across Aotearoa to support their tertiary studies in business, banking and finance. Investing in local communities Since 2014, we have supported Little Wings, a children’s charity providing free aeromedical transport for seriously ill children in regional and remote communities. Operating from Bankstown, Cessnock and Brisbane airports, Little Wings completes more than 2,300 missions annually. Our partnership, formalised in 2020, helps fund its Medical Wings program, which brings city-based specialists to regional clinics each month. Building on the success of our existing partnership with National Rugby League, we announced a new sponsorship with Cricket Australia. Our support directly contributes to initiatives that elevate participation and visibility of both sports, from grassroots clubs to elite competition. This includes pathway and development programs for schools, young females and First Nations talent to grow the next generation of players and leaders. BUILDING BRIGHT FUTURES Country Education Foundation of Australia (CEF) is a volunteer led organisation helping thousands of young people in regional, rural and remote communities to pursue education and training after school. Operating through 49 local foundations across five states and territories, CEF is powered by more than 400 dedicated volunteers who fundraise, award grants and mentor students, ensuring that distance and disadvantage don’t stand in the way of opportunity. St.George Foundation has awarded a three-year, $300,000 Inspire grant to CEF to help students like Piper (pictured) continue their studies and build bright futures. 1. In FY25, Westpac Group provided support to the Westpac Community Trust and the Westpac Buckland Fund (known as the Westpac Foundation), Westpac Scholars Trust and the St George Foundation Trust (known as St George Foundation, BankSA Foundation and the Bank of Melbourne Foundation). While Westpac was involved in establishing these foundations, they are non-profit organisations that are separate to the Westpac Group. The trustee of St George Foundation Trust (St George Foundation Limited) is a related body corporate of Westpac. 2.

172 WESTPAC GROUP 2025 ANNUAL REPORT CREATING VALUE FOR THE COMMUNITY Respecting and advancing human rights We recognise that our activities and relationships can affect the human rights of our people, customers and communities. We are committed to respecting these rights and actively seek opportunities to support and advance them. We have a long-standing commitment to social impact and human rights leadership, having introduced our first Human Rights Position Statement and Action Plan a decade ago. We continue to progress and update our approach where appropriate, to ensure it remains relevant, aligned to our purpose and reflects expectations and standards. The current Human Rights Position Statement and Action Plan sets out our stance on respecting and advancing human rights and the actions we are taking. We also support the UN Guiding Principles on Business and Human Rights, which informs the way we identify, assess and address human rights and modern slavery risks and impacts across our operations and supply chain. The outcomes of customer and supplier assessments are published each year in the 2025 Sustainability Index and Datasheet. More information on Westpac's approach to human rights due diligence, grievance mechanisms and remedy can be found on the Human Rights section of our website and in the Modern Slavery Statement. We are making good progress on the actions outlined in the Human Rights Position Statement and Action Plan, with delivery expected by May 2026 across five strategic priorities. Strategic focus areas FY25 Progress Addressing our salient human rights issues Completed the final phase of our Human Rights Risk Assessment (HRRA). This identified eleven salient human rights issues that represent our most significant areas of human rights risk. Refer to the 2025 Sustainability Index and Datasheet for detailed results. Strengthening grievance mechanisms and approach to remedy Developed a grievance mechanism to respond to human rights concerns from people impacted by our lending to large businesses, incorporating feedback from human rights experts, investors and civil society. We expect to pilot the mechanism in FY26. Supporting and advancing human rights through a just and inclusive transition Developed principles and three action areas to guide our approach to a just transition as we support those more impacted by extreme weather events and the transition to a net-zero economy. Refer to the Climate Transition Plan for more information. Strengthening a focus on child safeguarding Launched a Safety by Design Toolkit for free use by the banking sector, in partnership with the Australian Banking Association. The Toolkit provides guidance on designing products and services to better safeguard customers from financial harm, including children and young people. Strengthening the foundations of our human rights approach Developed an approach to deliver enterprise-wide human rights and modern slavery training and capability improvements. We also finalised a monitoring framework to track and report on our salient human rights risks. SAFEGUARDING CHILDREN Since 2020, Westpac’s Safer Children, Safer Communities (SCSC) Program has committed more than $80 million to more than 50 organisations across Australia and Asia. While funding under the SCSC initiative is now fully allocated, our commitment to child safeguarding continues through our participation in the On Us: Australian Business Coalition for Safeguarding Children and associated Child Safeguarding Business Principles, which guide businesses in recognising and managing their potential or actual risks on children’s safety and wellbeing. The Principles align with national efforts led by the Australian Government to improve child safety across industries and provide a clear, actionable framework for embedding child safety into business operations, risk management and culture.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 173 Ensuring reliable access to cash Maintaining access to cash in communities across Australia carries significant cost. We continue to balance these costs against our responsibility to ensure financial inclusion, particularly for vulnerable customers and regional communities. Our total cost of supplying cash services to Australians was approximately $350 million. This included our continued financial support for Armaguard to help maintain the stability of the national cash distribution system. We are working with government, regulators and industry partners to shape a long-term, sustainable solution for Australia's wholesale cash supply. For information on the other ways we're supporting regional Australia, refer to page 164. Maintaining a sustainable and diverse supply chain We aim to build a stronger, more inclusive society by supporting businesses that create positive change. Through our Supplier Inclusion and Diversity program, we support Indigenous-owned businesses, social enterprises, Australian Disability Enterprises, women-owned businesses and B Corporations - companies certified for their high standards of social and environmental performance, transparency and accountability. We spent $56.1 million with diverse suppliers1 , an increase of $18.2 million from last year. Please refer to the table below for information on how we support Indigenous-owned businesses. Supporting Reconciliation and Indigenous peoples Our vision for reconciliation is an Australia where Aboriginal and Torres Strait Islander peoples have equitable opportunity for economic participation and financial wellbeing. We seek to achieve this through a focus on creating impact for Indigenous customers, employees and communities. The outcomes of the 2022-2025 RAP set out below demonstrate our ongoing commitment to achieving our vision. Our new 2026-2028 Reconciliation Action Plan (RAP) signifies a sharper focus across five priority areas, including Indigenous banking, supporting suppliers, home ownership, Westpac careers and Free, Prior and Informed Consent (FPIC). RAP FOCUS AREA FY25 PROGRESSa Valuing culture: building relationships based on trust and respect; valuing cultures and histories and recognising the importance of self-determination. • Maintained cultural capability with 99.8% of employees completing mandatory learning. • Celebrated and supported Indigenous culture by hosting more than 30 events internally and externally for National Reconciliation Week and NAIDOC Week. • Platinum Sponsor of Garma, a major event celebrating Indigenous culture. • 20 Westpac staff completed a Jawun secondment this year, bringing the total to 100 secondments since April 2022. Meaningful careers: investing in Indigenous careers through dedicated programs to recruit, retain and develop Aboriginal and Torres Strait Islander people. • Aboriginal and Torres Strait Islander workforce representation rose to 1.15% though retention challenges have slowed progress towards our 1.5% target. To address this, we’ve appointed a First Nations Engagement Manager to develop and implement a retention and development strategy for Indigenous employees. • We recruited 11 new cadets through MobTech, all of whom secured permanent roles at Westpac. Better banking experiences: making it easier for Indigenous customers to do business with us and improving financial inclusion and economic participation. • 18,008 unique customers have been supported through our Indigenous call centre since April 2022. • Since 2022, we’ve delivered 146 Remote Services. Backing Indigenous enterprise: helping more Aboriginal and Torres Strait Islander people to grow their businesses as customers, suppliers and partners. • We spent $35.1 million with Indigenous-owned suppliers this year, bringing the total since April 2022 to $67.9 million. This significantly exceeds our RAP target to spend a cumulative $8 million with Indigenous-owned suppliers between 1 April 2022 and 30 September 2025. • Skilled Volunteer Network supported 26 First Nations-focused organisations, including 7 First Nations-led organisations. Respect for self-determination and a deeper understanding of FPIC: working with customers, stakeholders, experts and communities to share knowledge and improve outcomes. • Guided by First Nations perspectives, we developed a framework to support conversations about engagement with customers and partnered with an Indigenous-led organisation to strengthen these principles. • Our 2022-2025 RAP leadership project supports FPIC implementation at Westpac. a.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 175 To support our purpose and climate ambition to become a net-zero, climate resilient bank, we continue to actively support the transition to a lower-carbon economy and enhance Westpac's climate resilience. This year we made good progress on our climate strategy. We further reduced operational emissions, advanced towards Westpac's 2030 financed emissions sector targets and recorded solid growth in sustainable finance and bond facilitation. We have also lifted our capability to analyse and assess climate-related risks and opportunities, by improving scenario analysis, introducing a climate risk policy and expanding training. This positions us well for the future by supporting our resilience and ability to meet new prudential standards and legislative reporting requirements. Westpac's new Climate Transition Plan (CTP), shaped by stakeholder feedback, outlines our targets and approach to supporting progress towards our climate ambition. The CTP supersedes our 2023-2025 Climate Change Position Statement and Action Plan. Refer to the 2025 Sustainability Report for more information. Reducing the direct impact of our operations We believe in leading through action, demonstrated by our progress towards achieving our operational emissions reduction targets. In FY23, we met our 2025 scope 1 and 2 operational emissions reduction target. In FY24, we delivered our 2030 operational emission target six years ahead of plan. Despite this, we remain focused on further reducing our impact, with scope 1 and 2 operational emissions declining a further 22%, largely from the transition of our fleet towards hybrid or electric vehicles (pictured). The 89% reduction since 2021 places us comfortably ahead of our 2030 target of a 76% decline. We have continued to source the equivalent of 100% of electricity from renewable sources. This has been supported by our long-term virtual power purchase agreements with the Bomen Solar Farm in New South Wales, Ararat Wind Farm in Victoria, and Berri Solar Farm and Battery in South Australia. Westpac’s operational emissions Upstream scope 3 emissions were down 2% in FY25 and 42% lower than the 2021 baseline year, putting us on track to achieve our target of a 50% reduction by 2030.

176 WESTPAC GROUP 2025 ANNUAL REPORT CREATING VALUE FOR THE ENVIRONMENT Supporting the customer transition With more than 99% of emissions linked to lending, reported as scope 3 financed emissions, helping customers to transition is where we are focusing our efforts to drive meaningful change. Our aspiration is to reduce Westpac's financed emissions in line with the goals of the Paris Agreement. It is complemented by 13 sector targets, including high-emitting industries. This year we reported improved progress for more than 70% of our financed emissions sector targets. We report financed emissions one year in arrears, so the most recent available data is from FY24. Westpac's total financed emissions were 40.7 MtCO2-e for FY241 , slightly higher than in FY23. This was primarily due to: • Adoption of a higher-quality source for emissions factors used to estimate customer emissions; and • A rise in the share of Business and Institutional lending for which we estimate financed emissions. As a part of managing sustainability risks in our lending, we updated our Carbon-Intensive Sector Requirements during the year. Existing customers in-scope of these requirements are now subject to a Customer Climate Transition Plan (CTP) Evaluation when they seek new or renewed corporate lending or bond facilitation. These requirements apply to customers operating in oil and gas, metallurgical coal mining and coal-fired power generation sectors and outline how we engage and consider financing decisions. The CTP Evaluation rates customers’ CTPs on a four-point scale of A to D and informs the actions we will take depending on the rating. If a customer CTP is rated ‘D’ they would not currently be eligible for new or renewed corporate lending or bond facilitation unless financing supported National or Energy Security2 . As we have worked to implement these requirements, we conducted a preliminary analysis of existing in-scope customers’ CTPs. In that review, approximately 55% were rated ‘A’ while 9% were rated ‘D’. Further information can be found in the 2025 Sustainability Report. We have delivered on our FY25 commitment to reduce corporate lending to institutional thermal coal mining customers3 to zero. In FY25, we had in-depth engagements with more than 130 institutional and corporate customers in Australia and New Zealand on their climate transition plans. Of these, 83% had a public report outlining their climate transition strategy. With the introduction of mandatory climate reporting, the maturity of our customers’ disclosures varies. To support our agriculture financed emissions sector targets, we have continued engaging with customers, industry bodies, and at key events. This included sponsoring Meat & Livestock Australia (MLA) Carbon EDGE workshops, which aim to help farmers reduce emissions through best practices in productivity, animal welfare and environmental management. In 2023, as part of setting 2030 Agriculture financed emissions sector targets for Dairy and for Beef and Sheep, we expressed a commitment to no deforestation4 from 31 December 2025 for customers in scope of our targets, and to engage with customers on this commitment. Since that release, we have engaged with rural research and development corporations, members of the agricultural supply chain, peak industry bodies and with customers to understand how this would affect the sector. Following our consultation, we have refined our approach, no longer requiring a formal ‘no deforestation’ commitment, but continuing to develop practical ways to help customers manage deforestation risk effectively. This includes supporting industry efforts that help farmers assess and verify deforestation free status for supply chain reporting. For more detail, refer to the 2025 Sustainability Report. Engaging with customers to better understand their decarbonisation approaches is critically important. By doing this, we can identify where we can offer support and play a meaningful role in the broader climate transition. Strengthening insights We took steps to broaden our scenario analysis by incorporating new data sources to evaluate risks at the customer property level. We also used geospatial mapping to identify regions more susceptible to climate-related impacts. This is improving our understanding of physical risks across our lending. In turn, it enables us to provide more targeted support to customers to help strengthen their climate resilience. Growing sustainable finance Sustainable finance and bond facilitation play a role in assisting customers as they transition. Supported by our Sustainable Finance Framework, sustainable finance lending has reached $39 billion and increased 37% during the year. Cumulative sustainable bond issuance has totalled $22 billion since the start of FY22 and rose 40% in FY25. This progress underscores our support for customers' sustainability objectives. It also helps to position us to achieve our 2030 targets of $55 billion in sustainable finance lending and $40 billion in cumulative bond facilitation. 1. Total financed emissions for scope 1 and 2, and for certain sectors where we estimate scope 3 emissions. 2. National or Energy Security – Circumstances where a government or regulator determines that additional supply, or maintaining current supply is necessary for national or energy security and Westpac’s funding is able to support such additional supply, in which case it may need to be escalated to an appropriate committee. 3. At 30 September 2025. In line with our Sustainability Customer Requirements, we have zero corporate lending and will no longer provide bond facilitation for Institutional customers with ≥15% of their three-year rolling average revenue coming directly from thermal coal mining. 4.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 177 Natural capital We continue to build capability and knowledge on nature-related risks and opportunities, in alignment with our Natural Capital Position Statement. This has helped us better understand our role in supporting customers and suppliers across our value chain on nature topics that are most material to them. At 30 September 2025, 14.2% of lending is in sectors defined by the Taskforce on Nature-related Financial Disclosures (TNFD)1 as having material nature-related dependencies and impacts. Further information is available in the 2025 Sustainability Index and Datasheet. Understanding material nature topics relevant to institutional customers We analysed nature-related disclosures of Australian institutional customers in TNFD priority sectors to better understand their material nature topics1 and inform our ongoing customer engagement. Of the customers reviewed, more than 35% identified at least one nature topic as a key sustainability topic2 , with freshwater, land and biodiversity most commonly cited. This was most prevalent in the food and beverage, paper and forest products, metals and mining, infrastructure and energy sectors. Progressing our approach in agriculture Using the TNFD LEAP framework3 we piloted an approach to assess nature-related dependencies for Australian agribusiness customers. The pilot used geospatial analysis to evaluate the potential dependency on water, native forest and world heritage sites. It provided insights into how agribusiness customers depend on nature and helps build understanding of potential risks and opportunities. We participated in the Australian Sustainable Finance Institute (ASFI) Natural Capital Advisory Group and Agriculture and Land Taxonomy Expansion Pilot Advisory Group, helping to shape draft criteria for the Integrating Nature into Finance research paper. Sustainable financing We continue to offer sustainable finance that encourages improved land use and biodiversity management. In FY25, Westpac: • Coordinated Arranger and Bookrunner for AirTrunk’s SYD1 and SYD2 term loan financing, supporting biodiversity, conservation and disaster relief, delivered through its social impact program; • Supported the structuring and issuance of an innovative nature-focused Sustainability-Linked Bond for Auckland Council. Refer to case study; and • Provided Sustainable Farm Loans to 48% of total agribusiness term lending in New Zealand, totalling NZ$4.02 billion. Supplier engagement We work with Westpac's Australian suppliers to understand their approach to circularity and nature. This has resulted in positive outcomes such as a reduction in packaging of IT equipment, increased volumes of forestry certified paper and the reuse of equipment and materials across our operations and value chain. Additionally, we strengthened our responsible sourcing program by introducing new criteria to assess circularity, reduce deforestation risks and impacts on critical habitats for medium and large suppliers. Environmental performance We also continue to monitor the environmental performance of our operations. Further information is available in the 2025 Sustainability Index and Datasheet. SUSTAINABILITY-LINKED BOND FOR AUCKLAND COUNCIL Westpac supported the structuring and issuance of an innovative nature-focused Sustainability-Linked Bond for Auckland Council. The NZ$250 million three-year wholesale bond is the first in Australasia to include a nature-based target, with Auckland Council targeting to plant one million native ngahere (forest) stems across its regional parks by the end of 2027. If the target is not achieved, Auckland Council will make a donation to organisations supporting the restoration of native ngahere across the Auckland region. Typically, Sustainability-Linked Bonds include additional payments to investors for missed targets. The structure of Auckland Council’s Sustainability-Linked Bond ensures that the Auckland community benefits, irrespective of whether the planting target is met. 1.

We have established a dedicated transformation office, led by a Chief Transformation Officer and supported by a skilled team, to drive effective transformation across Westpac. UNITE, our business-led, technology-enabled transformation program, is a cornerstone of this agenda. It aims to simplify operations and enhance experiences by consolidating technology stacks, decommissioning legacy systems and streamlining our product suite to make banking simpler for customers. To choose the best path for UNITE, we’ve adopted a 'one best way' approach to deliver Westpac consistently across our channels, processes and products. UNITE comprises four stages: Discovery, Simplify, Implement and Decommission. The Discovery stage is complete, with 51 initiatives underway and eight delivered. Modernising technology Complementing UNITE are two flagship digital innovations, BizEdge and Westpac One. BizEdge, our new business lending origination platform, is accelerating digital capabilities for bankers, with AI-powered tools that support faster, more confident decision-making. Westpac One, our new Institutional platform, will integrate treasury, FX trade and lending with real-time data insights to enhance customer experience and operational performance. These initiatives reflect our commitment to making Westpac simpler, while modernising how we work to deliver better outcomes for customers and our people. UNITE: ONE PRIVATE BANK We completed a successful transition of customers to a single, Private Bank under the Westpac brand. This strategic initiative was designed to enable more customers to benefit from Westpac's enhanced digital experience and improved service offering. Customers who transitioned gave positive feedback, which reflected in a strong Brand NPS1 result for Private Bank. The initiative cost $5 million to complete and has cut related processes and systems by 50%, reducing duplication and streamlining banker workflows. Additionally, it supports our aim to grow Private Bank's balance sheet and funds under management.

More than 3,600 people engaged in the CEO-sponsored AI Shark Tank, showcasing the energy and creativity of our people in applying AI to real-world challenges. Refer to page 167 for more information. Responsible AI and governance We are committed to the ethical, safe and transparent use of AI, supported by a robust governance framework and evolving risk reporting mechanisms to ensure responsible development. We’re guided by Westpac’s Responsible AI Principles, along with our AI Risk Management Standard (AIRMS) and Responsible AI Playbook. Together, they shape how we use AI while ensuring we maintain an external lens that reflects both community expectations and regulatory requirements. Our leadership in this space was recognised internationally, with Westpac shortlisted for the 2025 DataIQ Awards UK in the category of 'Best Responsible AI Program', highlighting our commitment to safe, scalable and ethical AI innovation. Accelerating AI innovation We have been using AI in different forms for more than a decade. Our focus today is on scaling proven generative AI solutions that have tangible benefits through our AI Accelerator. It has delivered 33 solutions to date with a further 27 in delivery. Some of its benefits include: • AI for customer safety: Our Fraud and Scams team are assisted on calls by 'JESS', our Joint Expert Scam Spotter. This AI capability delivered real-time guidance during 20,000 customer calls, yielding unique insights and helping to protect customers from scams and fraud. • AI for faster lending decisions: The Mortgage AI Assessor introduced last year is now supporting 700 assessors to process mortgage applications, saving more than 12,000 hours of assessor time annually. • AI to empower our people: 15,724 employees are actively using Gen AI tools, exceeding our FY25 target of 10,000. We've deployed 10,600 Microsoft 365 Copilot licenses, including access to personal agents via Copilot Studio Lite, enabling staff to interact with data using natural language in a secure environment. A pilot group is now live on Copilot Studio's advanced AI agent capabilities, expediting AI Shark Tank opportunities. • AI for efficiency: Our use of Agentic AI in Data Products is transforming how we work, enabling autonomous AI agents to deliver outcomes up to twelve times faster and helping scale GenAI solutions across the organisation. In recognition of this innovation, we were proud to be named a finalist in the 2025 Finovate Awards in New York. FINANCIAL CRIME AI: SMARTER SURVEILLANCE AT SCALE Westpac has developed an innovative AI-based system to improve its financial crime investigation capability. It can automatically summarise analysis from large volumes of data, making it easier to identify risks and act quickly. By cutting down on manual work, the system supports teams to make faster, more consistent decisions. This helps us to focus on new threats while freeing up our teams to support more customers.

180 WESTPAC GROUP 2025 ANNUAL REPORT RISK MANAGEMENT Proactive risk management and a strong risk culture are essential to Westpac’s strength and resilience. They guide the organisation’s operations and decision-making and support our ability to adapt to a changing environment. Westpac’s risk management framework (Framework) outlines how the organisation manages its material risks and delivers better outcomes for customers, communities, its people and other stakeholders. The Framework is centred around customers, a strong risk culture and an effective Three Lines of Defence (3LOD) model. The Risk Management Strategy, which incorporates the Framework, is approved by the Board. It is supported by risk class frameworks, risk appetite statements and policies. These are all reviewed regularly to maintain the effectiveness of the Framework. For further information on the risks we face, refer to 2025 Risk Factors.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 181 Strengthening risk management In December 2020, Westpac entered a Court Enforceable Undertaking (CEU) with The Australian Prudential Regulation Authority (APRA). We committed to remediating specific prudential weaknesses identified by APRA in our culture, governance and accountability, and address the root causes of these issues. In response, Westpac established the Customer Outcomes and Risk Excellence (CORE) Program and appointed an independent reviewer. Prior to this, APRA had imposed a $500 million operational risk capital overlay on Westpac in July 2019 and an additional $500 million operational risk capital overlay in December 2019. In recognition of the progress and improvements in risk management under CORE, in July 2024, APRA reduced its operational risk capital requirement by $500 million. In October 2025, APRA removed the remaining $500 million risk capital overlay, satisfied that the CORE program is complete and the specific prudential issues identified by APRA have been addressed. Promontory Australia, the independent reviewer noted in their final report on the CORE program: “The depth of change to the organisation, both structurally and culturally, means that Westpac is now a simpler, stronger bank." Three Lines of Defence (3LOD) PRINCIPLES First Line owns and manages the risks they originate: − The First Line proactively identifies, evaluates, owns, monitors, manages and controls the existing and emerging risks in their business. It manages business activities within approved risk appetite and policies. − In managing its risk, the First Line establishes and maintains appropriate governance structures, controls, resources and self-assessment processes, including issue identification, recording and escalation procedures. The 3LOD work together to deliver effective risk management outcomes to achieve the Group's Purpose. The 3LOD work together to make sound risk-based decisions through: − strong and proactive engagement, communication, trust and collaboration − management information that is reliable, coherent and transparent. There must also be alignment of activities across the 3LOD to avoid unnecessary duplication, overlap, or gaps. Third Line provides independent and objective assurance: − Group Audit is the Third Line assurance function that provides the Board and Senior Executive with independent and objective evaluation of the adequacy and effectiveness of the Group’s governance, risk management and internal controls. 3LOD IN WESTPAC Second Line provides insight, oversight and challenge of First Line activities: − The Second Line is an independent function that develops risk management frameworks, defines guardrails, provides objective review and challenge regarding the effectiveness of risk management within the First Line business, and executes specific risk management activities where functional independence and/or specific risk capability is required. − Its approach is risk-based and proportionate to First Line activities.

182 WESTPAC GROUP 2025 ANNUAL REPORT RISK MANAGEMENT Material risk categories Westpac has identified 11 material risk categories, among other potential risks, that could impact its business activities. 1 Capital Adequacy 2 Funding and Liquidity Risk 3 Credit Risk 4 Market Risk 5 Strategic Risk 6 Risk Culture 7 Operational Risk 8 Compliance and Conduct Risk 9 Financial Crime Risk 10 Cyber Risk 11 Reputational and Sustainability Risk For each material risk category, the Board establishes a risk appetite which is articulated in the Board Risk Appetite Statement (RAS). The RAS lists our material risks, along with the measures and tolerances used to monitor each risk. Most of these measures are monitored by 'green', ‘amber’ and ‘red’ tolerances which indicate when risks are close to, or over, the Board’s approved appetite. The following table provides more detail. MATERIAL RISK CATEGORIES 1 Capital Adequacy Risk The risk that Westpac has an inadequate level or composition of capital to support its normal business activities and to meet its regulatory capital requirements. Risk Appetite and Mitigation We aim to maintain a strong balance sheet including under stressed scenarios. We evaluate capital management through our Internal Capital Adequacy Assessment Process, features of which include: • Capital management strategy; • Considering economic and regulatory requirements and stakeholder perspectives; • Stress-testing considerations; and • Target operating range for key capital ratios. Areas of focus include: • Continuous monitoring of capital forecasts; • Considerations of capital headwinds; and • Actively monitoring the economic outlook and credit risk arising from higher interest rates and cost-of-living pressures. Example of a Risk Appetite measure • CET1 capital ratio – a measure which indicates a bank’s capacity to absorb losses.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 183 2 Funding and Liquidity Risk The risk that Westpac cannot meet its payment obligations or that it does not have the appropriate amount, tenor and composition of funding and liquidity to support its assets. Risk Appetite and Mitigation We aim to manage our balance sheet such that we: • Maintain a diversified, stable and cost-effective funding base; • Can source funding as and when needed; • Have sufficient securable assets to meet our funding and repurchase agreement requirements; and • Fund lending growth with stable funding sources. Further information on funding and liquidity risk management is in Note 21 (page 73). Areas of focus include: • Executing the wholesale funding plan to support balance sheet growth and refinance maturing debt; and • Managing liquidity risk to meet regulatory requirements and Westpac’s liquidity needs in line with market conditions. Examples of a Risk Appetite measure • Net Stable Funding Ratio (NFSR); and • Liquidity Coverage Ratio (LCR). 3 Credit Risk The risk of financial loss where a customer or counterparty fails to meet their financial obligations to Westpac. Risk Appetite and Mitigation We manage credit risk using: • Board approved credit risk limits and approval authorities which are cascaded through the bank; • Clear boundaries to guide appropriate credit risk strategic choices • Reviewing settings and appetite on a regular basis to adjust for changes in the operating environment; and • A range of policies, processes and systems to support credit risk monitoring and management. Further information on credit risk management and provisioning is in Note 10 (page 33) and Note 11 (page 43) to the financial statements and in the September 2025 Pillar 3 report. Areas of focus include: • Responding to heightened credit risk from domestic and international factors including cost of living pressure, higher interest rates, ongoing geopolitical risks, trade disruptions and a more uncertain economic environment; • Stress testing our credit portfolio including for climate related change and the transition to net-zero emissions; and • Assessing the impact of any external events, and provision modelled outcomes including lending growth and conditions for specific customer groups (e.g. including by geography, industry etc.) the adequacy of the overall expected credit loss provision. Example of a Risk Appetite measure • Top 10 exposures to Corporates and Non-Bank Financial Institutions as a % of Total Committed Exposure.

184 WESTPAC GROUP 2025 ANNUAL REPORT RISK MANAGEMENT 4 Market Risk The risk of an adverse impact on Westpac’s earnings and economic value resulting from changes in the value of Westpac’s positions due to a change in financial market factors, such as foreign exchange rates, commodity prices, equity prices, credit spreads and interest rates. This includes earnings at risk – the risk to net interest income from interest rate changes, and economic value sensitivity – the risk of variability in the Group’s banking book capital requirements. Risk Appetite and Mitigation We have appetite for market risk in approved products within our limit framework. We manage market risk through the employment of prudent risk management strategies and active monitoring of Board-approved metrics that capture the potential risk of adverse movements in financial markets. The Board has approved a risk appetite for traded and non-traded risks via the measurement of Value at Risk (VaR), Stressed VaR (SVaR), Net Income at Risk (NaR) and risk sensitivities to interest rates for capital hedges and to credit spreads for the liquid securities portfolio. The management of market risk is supported by the Market Risk Management Framework and associated policies, limits, processes, systems and delegated authorities. Further information on market risk management is in Note 21 (page 73). Areas of focus include: • Upgrading/replacing market risk systems and supporting infrastructure; and • Implementing regulatory change related to prudential market risk standards. Example of a Risk Appetite measure • Value at Risk (VaR), a statistic that quantifies the extent of possible financial losses arising from the Bank’s Treasury and Financial Markets businesses. 5 Strategic Risk The risk that Westpac makes inappropriate strategic choices, does not implement its strategies successfully, or does not respond effectively to changes in the environment. Risk Appetite and Mitigation We aim to grow through well-considered initiatives aligned to our strategy and risk appetite. We aim to manage the impact of threats from changes in the environment, which could significantly impact our ability to implement our strategies. We continually evaluate our performance and seek to adapt to changes in the external environment in a timely manner. Areas of focus include: • Technology simplification and transformation; • Delivery of regulatory commitments; and • Invest in digital and data, with the aim of improving the customer experience. Examples of a Risk Appetite measure • Actual ROTE against the Target ROTE; and • Allocation of balance sheet to Australia and New Zealand (% of book in terms of Exposure at Default).

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 185 6 Risk Culture The risk that our culture does not promote and reinforce behavioural expectations and structures to identify, understand, discuss and act on risks. Risk Appetite and Mitigation We promote a risk culture that supports our purpose, strategy and values and our ability to manage risk effectively. We regularly assess our risk culture and undertake initiatives to continually improve. Areas of focus include: • Leader led role modelling and training; • Continuing to review, monitor and improve our tools and processes to support the management of risk culture; • Supporting improved capability across key behavioural change areas, including speak up, decision making, ownership, challenge and maturing action planning to drive behavioural change; and • Executing on an integrated culture plan to support driving change at all levels. Example of a Risk Appetite measure • Internal survey results – score for respondents who feel free to speak up without fear of negative consequences. 7 Operational Risk The risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. Risk Appetite and Mitigation We aim to be resilient to operational risk and minimise risk through robust processes and controls. We aim to quickly and effectively remediate material operational issues and incidents. Areas of focus include: • Strengthening the control environment, including risk prevention and automation; and • Strengthening our operational resilience and adopting read-across processes to fully understand underlying issues. Example of a Risk Appetite measure • % of key controls assessed as ‘Unsatisfactory’. 8 Compliance and Conduct Risk The risk of failing to abide by compliance obligations required of us, or otherwise failing to have behaviours and practices that deliver suitable, fair and clear outcomes for customers and that support market integrity. Risk Appetite and Mitigation We establish robust controls and systems to manage compliance and conduct risk. We aim to promptly own, investigate and remediate incidents of non-compliance. We aim to prevent: • Breaches of regulatory requirements; • Conduct that causes unsuitable, unfair or unclear customer outcomes or adversely impacts the integrity of markets; and • Complicated systems or processes that could lead to systemic or material breaches of regulatory requirements. Areas of focus include: • Strengthening the management of our conflicts of interest, product governance, privacy risks and the oversight of regulatory reporting; and • Improving our tools and processes to support alignment of our behaviours and business practices to fair customer outcomes and market integrity. Example of a Risk Appetite measure • Average calendar days to complete all Compliance Assessments.

186 WESTPAC GROUP 2025 ANNUAL REPORT RISK MANAGEMENT 9 Financial Crime Risk The risk that Westpac fails to prevent products and services being used to facilitate financial crime, fails to protect customers and Westpac from fraud and scam events or fails to comply with applicable global financial crime regulatory obligations. Risk Appetite and Mitigation Westpac is committed to protecting the integrity of the Australian financial system and importantly keeping our community safe. This aligns with our purpose of ‘Taking action now to create a better future’. Westpac helps prevent financial crime by proactively identifying, assessing, mitigating and reporting financial crime risks and complying with all applicable global and local financial crime regulatory obligations. Westpac continues to invest significant resources to assist AUSTRAC, law enforcement and the Australian Government (including through the Fintel Alliance) to detect, deter and disrupt financial crime. Areas of focus include: • Simplification and embedding strategic capabilities, improving detection and surveillance capabilities and expanding the use of network analytics; • Collaboration through involvement in Public and Private sector partnerships and other intelligence bodies to disrupt financial crime; and • Uplifting of Know your Customer (KYC) processes and enhancing customer lifecycle management through digital capabilities and automated controls. Example of a Risk Appetite measure • Volume of High/Very High Financial Crime residual risk ratings across Westpac's businesses. 10 Cyber Risk The risk that Westpac’s or its third parties’ data or technology are inappropriately accessed, manipulated or damaged from cyber threats or vulnerabilities. Risk Appetite and Mitigation We proactively manage our cyber risk exposure, to help ensure that we are resilient to cyber threats and vulnerabilities. In managing our cyber risk, we aim to ensure that: • We manage our risks within the appropriate regulatory frameworks; • We do not undermine our strategic, financial, reputational or regulatory standing; and • We implement cyber controls commensurate to the cyber threats we respond to. We recognise that cyber events may occur, however incidents must be managed timely and effectively to limit impact and future likelihood. Areas of focus include: • Enhancing cybersecurity capability including data security controls, application protection controls, identity and access management and strengthening our network perimeters; and • Embedding a consistent cyber risk management framework. Examples of a Risk Appetite measure • Control effectiveness against external cyber threats; and • Supplier security assessment outcomes.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 187 11 Reputational and Sustainability Risk The risk of failing to recognise or address environmental, social or governance (ESG) issues as well as the risk that an action, inaction, transaction, investment or event will reduce trust in Westpac’s integrity and competence. Risk Appetite and Mitigation We aim to maintain the confidence of all stakeholders, aiming to balance the commercial aspects of decisions with stakeholder expectations. Our approach includes considering potential impacts on people, communities and the environment. We recognise that ESG issues can involve interconnected and sometimes competing considerations. Areas of focus include: • Continuing to improve assessment of customers and our supply chain for reputation and sustainability risks through existing governance processes and tools; • Continuing to embed the Climate Risk Policy, aligned with APRA’s CPG 229, including performing a Climate Risk Materiality Assessment to understand the intersection of climate risk across our material risk categories; and • Expanding our salient human rights assessment to include our role as a financial services provider, employer and supporter of communities. Example of a Risk Appetite measure • Reputation ranking from external ranking agency (such as RepTrak) which provides independent assessments of a company’s reputation, brand and ESG.

192 WESTPAC GROUP 2025 ANNUAL REPORT CORPORATE GOVERNANCE Board skills, experience and attributes Westpac seeks to maintain a Board of Directors with a broad range of relevant financial and other skills, knowledge, and experience necessary to guide the business of the Group. The Board uses a skills matrix to illustrate the key skills and experience the Westpac Board is seeking to achieve in its membership collectively and the number of Directors with each skill and experience. The skills matrix also assists to identify focus areas for the continuing education and professional development of Directors. For example, in FY25 these focus areas included technology developments and key environmental, social and governance topics (amongst others), which were facilitated through a combination of structured workshops, targeted deep dives, and site visits aligned with strategic priorities. The skills matrix also assists to identify areas where it may be desirable for specialist external expertise to be retained to supplement the Board’s skills and experience. The skills matrix is set out in Figure 1. FIGURE 1 – BOARD SKILLS, EXPERIENCE AND ATTRIBUTES AS AT 30 SEPTEMBER 2025 SKILLS AND EXPERIENCE DESCRIPTION NUMBER OF DIRECTORS Customer focus Experience in developing and overseeing a strong customer-focused culture in large and complex organisations, and a demonstrable commitment to achieving customer outcomes Strategy An ability to define strategic objectives, constructively question business plans, oversee the implementation of strategy using commercial judgement and bring a global perspective to bear Financial services Experience working in, or advising, the banking and financial services industry with strong knowledge of its economic drivers and global business perspectives Financial acumen Highly proficient in accounting or related financial management and reporting for businesses of significant size Risk management Experience in anticipating, recognising and managing risks, including financial, non-financial and emerging risks, and monitoring risk management frameworks and controls Technology, digital and data Experience in overseeing the application of technology in large and complex organisations, including in areas such as innovation, disruptive technologies, data, cyber-security, digital transformation and customer experience Governance Experience as a Director of a listed entity, with detailed knowledge of governance, including legal, compliance, regulatory and public policy issues applicable to listed entities and highly regulated industries Environment and social Experience in understanding and identifying potential risks and opportunities arising from environmental and social issues People and culture Experience in people matters including workplace health and safety, cultures, morale, inclusion and diversity, management development, succession, remuneration and talent retention initiatives Executive leadership Having held a CEO or a similar senior leadership role in a large complex organisation, and having experience in managing the business through periods of significant change and delivering desired business outcomes Deep experience and knowledge General working experience and knowledge Limited working experience and knowledge In addition to the skills outlined above, the Westpac Board seeks to ensure that it operates as a cohesive team, bringing together a range of perspectives to guide the Group and oversee management.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 193 Board diversity A diverse group of skilled Directors helps us be a stronger organisation that makes better decisions. In relation to gender diversity, for 2025, the Board Nominations & Governance Committee confirmed its objective of 40% women, 40% men and 20% any gender for the composition of the Westpac Board. In FY25, this objective included the Managing Director and CEO. From FY26, the Managing Director and CEO will be included within the Executive Team objective, with the Board objective applying only to Non-executive Directors1 . As at 30 September 2025, the gender composition of the Board was 64% male and 36% female. Independence All Non-executive Directors satisfy our criteria for independence, which aligns with the guidance provided in the ASXCGC Recommendations. The Board assesses the independence of our Non-executive Directors on appointment and annually. Each Non-executive Director provides an annual attestation of their interests and independence. Directors are considered to be independent if they are independent of management and free from any business or other relationship that could materially interfere with, or could reasonably be perceived to materially interfere with: • the exercise of their unfettered and independent judgement; and • their ability to act in the best interests of Westpac as a whole rather than the interests of another party. Materiality is assessed on a case-by-case basis by reference to each Non-executive Director’s individual circumstances rather than by applying general materiality thresholds. Each Non-executive Director is required to disclose any business or other relationship that they have directly, or as a partner, shareholder or officer of a company or other entity that has an interest or a business or other relationship with Westpac or a Group entity. The Board considers information about any such interests or relationships, including any related financial or other details, when it assesses the Non-executive Director’s independence. APPOINTMENT OF DIRECTORS The Board Nominations & Governance Committee considers and makes recommendations to the Board on candidates for appointment as Directors. Such recommendations pay particular attention to: • the mix of skills, experience, expertise, diversity, independence, and other qualities of existing Directors; and • how the candidate’s attributes will balance and complement those skills and qualities, and address any potential skills gaps in relation to the current and future composition of the Board. Subject to the Constitution and ASX Listing Rules, the Board may appoint a Director, either to fill a casual vacancy or as an addition to the existing Directors. Except for the CEO, a Director appointed by the Board holds office only until the close of the next annual general meeting (AGM) but is eligible for election by shareholders at that meeting. Our Constitution states that a Director (except for the CEO) must not hold office (without re-election) past the third AGM following their appointment or last election, or for more than three years, whichever is longer. Retiring Directors hold office until the conclusion of the meeting at which they retire but are eligible for re-election at that meeting. Our Constitution also provides that at least one Director must stand for election or re-election at each AGM. This requirement could be satisfied by a person standing for election as a new Director; a Director who has been appointed to fill a casual vacancy seeking election; or a Director seeking re-election because of the tenure limitation (referred to in the paragraph above). If there are no such Directors required to stand for election or re-election at the AGM, and no Director volunteers to stand for re-election, the Director who has served the longest in office since their last election or re-election must retire and stand for re-election. The CEO is not required to stand for re-election. Prior to a Director’s appointment or consideration for election or re-election by shareholders, the Board conducts due diligence and considers the results of the Board performance evaluation conducted during the year. Where a Director is seeking election or re-election, Westpac provides shareholders with all material information relevant to a decision on whether or not to elect or re-elect a Director. New Directors receive an induction pack and letter of appointment setting out the expectations of the role, and conditions of appointment including the expected term of appointment and remuneration. This letter aligns to the ASXCGC Recommendations. All new Directors participate in an induction program to familiarise themselves with our business and strategy, culture, commitments and 1. The Westpac Director Appointment & Renewal Policy outlines considerations for the appointment of candidates, including gender diversity for the appointment of Non-executive Directors to the Westpac Board. The Managing Director and CEO is appointed to the Westpac Board due to their executive position.

The induction program includes an opportunity to review key documents and meet with a range of representatives from the organisation, including the Chairman, the CEO, the Board Committee Chairs and each Group Executive. The Westpac Director Appointment & Renewal Policy limits the tenure of office that any Non-executive Directors other than the Chairman may serve to 9 years, from the date of first election by shareholders. The maximum tenure for the Chairman is 12 years (which includes any term served as a Director prior to being elected as Chairman), from the date of first election by shareholders. The Board, on an exceptional basis, may extend the maximum terms specified above where it considers the extension would benefit the Group. The Board may exercise this discretion on an annual basis, and the Director concerned will be required to stand for re-election annually. The average Board tenure as at 30 September 2025 is set out below. The length of service of each Director is set out in the Directors’ report in our 2025 Annual Report. Conflicts of interest All Directors are required to disclose to the Board any actual, potential or apparent conflicts of interest upon appointment and are required to keep these disclosures up to date. Any Director with a material personal interest in a matter being considered by the Board must declare their interest and may not be present during any related boardroom discussions nor vote on the matter unless the Board resolves otherwise. Continuing education Directors undertake continuing education and training to develop and maintain the skills and knowledge needed to perform their role effectively, including by participating in workshops held throughout the year, attending relevant site visits, and undertaking relevant external education. These activities are planned each year and are included in the Board’s/Board Committees’ calendars. In addition, the Board and Board Committees consider whether additional education and professional development opportunities should be offered as part of the annual Board Effectiveness Review. Access to information All Directors have unrestricted access to company records and information required to perform their duties, and receive regular detailed financial and operational reports from senior management. Each Director also enters into an access and indemnity agreement, which among other things, provides for access to documents for up to seven years after their retirement as a Director. The Chairman and other Non-executive Directors regularly consult with the CEO, CFO and other senior executives, and may consult with, and request additional information from, any of our employees. Access to advice All Directors have access to advice from senior internal legal advisers including the Group General Counsel. The Board collectively, and all Directors individually, can also seek independent professional advice, at Westpac's expense, to help them carry out their responsibilities. While the Chairman’s prior approval is needed, it may not be unreasonably withheld. Remuneration framework Information about our remuneration framework, including policies and practices regarding the remuneration of Non-executive Directors, the CEO and other senior executives, is included in the Remuneration Report in the Directors’ report (which is located in our 2025 Annual Report). Westpac does not provide performance-based remuneration or retirement benefits (other than superannuation) to Non-executive Directors. The Remuneration Report also includes details of Westpac’s hedging policy, which prohibits participants in equity plans from entering into transactions that mitigate the risk associated with the equity award.

198 WESTPAC GROUP 2025 ANNUAL REPORT CORPORATE GOVERNANCE Board and Board Committee meetings The number of meetings of the Board and Board Committees for the financial year ended 30 September 2025, and each Director’s attendance is reported in the Directors' meetings section of the Directors’ report, in our 2025 Annual Report. Scheduled meetings of the Board Committees occur at least quarterly, with the Board Risk Committee meeting at least five times annually. All Board Committees can meet more frequently as necessary. Non-executive Directors regularly meet without management present, so they can discuss issues appropriate to such a forum. Senior executives and other selected employees are invited, where considered appropriate, to participate in Board and Board Committee meetings. They are also available to be contacted by Directors between meetings. All Directors can receive all Board Committee papers and can attend any Board Committee meeting, provided there is no conflict of interest. The CEO attends all Board Committee meetings, except where they have a material personal interest in a matter being considered. Board Audit Committee financial knowledge All Board Audit Committee members have appropriate financial experience, an understanding of the financial services industry and satisfy the independence requirements under the ASXCGC Recommendations, Securities Exchange Act of 1934 (US) (as amended) and its related rules. The Board has determined that Mr Nash is an ‘audit committee financial expert’ and independent in accordance with US securities law. The designation of Mr Nash as an audit committee financial expert does not impose duties, obligations or liability on him that are greater than those imposed on him as a Board Audit Committee member, and does not affect the duties, obligations or liability of any other Board Audit Committee member or Board member. Audit committee financial experts are not deemed as an ‘expert’ for any other purpose.

200 WESTPAC GROUP 2025 ANNUAL REPORT CORPORATE GOVERNANCE The Board approved a change to measurable objectives for gender diversity from FY26 to enhance our focus on achieving gender diversity throughout the organisation. Our aim is to achieve gender diversity of 40:40:20 at all role levels by FY30, with 40% women, 40% men and 20% of any gender. This new objective allows us to be inclusive of all gender identities and applied at all levels is key to improving our gender pay gap. We are committed to achieving pay equity. We undertake like-for-like and by-level analysis to identify potential gender-based pay equity issues and take action when needed.

Our Discrimination, Harassment, Bullying, and Related Conduct and Sexual Harassment policies are available at the following link www.westpac.com.au/ about-westpac/inclusion-and-diversity/. Our ‘Upstander’ initiative aims to grow employee confidence and capability to speak up and take action against behaviours and activities that negatively impact others. We have made progress against our commitments in our fifth Reconciliation Action Plan. Aboriginal and Torres Strait Islander workforce representation rose to 1.15%, though retention challenges have slowed progress towards our 1.5% target. We have implemented measures to support our Indigenous employees, including our Echo leadership and mentoring programs that are designed to support emerging leaders by building leadership capability and career progression. We have also appointed a First Nations Engagement Manager to further develop and implement retention and development strategies for Indigenous employees. We provide mandatory online Indigenous cultural learning to our employees, with an enhanced learning option also available. Our next Reconciliation Action Plan will launch in FY26. Our ten Employee Advocacy Groups help us strengthen an inclusive culture by building trusted communities that celebrate and advocate for gender, LGBTQIA+, young and mature-age employees, cultural diversity in leadership, accessibility, Indigenous employees, veterans, skilled volunteering and supporting victims of domestic and family violence. Westpac offers workplace flexibility and provides employees with a variety of leave options such as parental leave (including support for those who experience pregnancy loss), leave to undergo fertility treatment or arrange adoption of foster care, carers’ leave, culture, wellbeing and lifestyle leave, career breaks, purchased leave, uncapped domestic and family violence support leave, gender affirmation leave, Sorry Business and Sad News leave, volunteer leave, defence reserves and emergency services leave.

They address important themes such as speaking up, ownership, collaboration and empowerment.

The Code goes beyond an obligation to comply with laws and policies and is a key aspect of improving conduct to seek to ensure fair outcomes for customers, communities and each other. The Code requires us to apply the ‘Should We?’ Test when making decisions and encourages our people to speak up when our standards are not being met. We take non-compliance with the Code seriously.

We are also subject to a range of external industry codes, such as the Banking Code of Practice and the ePayments Code. Code of Ethics for Senior Finance Officers Our Code of Accounting Practice and Financial Reporting (COAPFR) complements our Code of Conduct. It is designed to assist our CEO, CFO and other principal financial officers to apply the highest ethical standards to their duties and responsibilities with respect to accounting and financial reporting.

The scope of, and limitations to, authority delegated by the Board to the CEO and through the CEO to other Group Executives, is articulated in delegation instruments and covers areas such as expenditure, funding and securitisation, and lending. These delegations help provide clarity on roles, authorities and responsibilities within the Group, and act as an internal tool of empowerment, control and risk management. Any matters or transactions outside the delegations of authority given to management are required to be referred to the Board or relevant Board Committee for approval.

The policy requirements also extend to associate accounts. In addition, Directors and any employees, secondees or contractors who, by virtue of their seniority or role, may have access to material non-public information about Westpac (known as Key Prescribed Employees and/or Prescribed Employees) are subject to additional trading restrictions. These include blackout periods, prohibiting trading prior to and immediately after release of the annual and half year results. These additional restrictions also apply to their associates.

Our senior management are committed to supporting those who speak up. Westpac does not tolerate detrimental conduct related to a Speaking Up report. A person can raise a concern using our whistleblowing channels, including our reporting system ‘Concern Online’ and our Whistleblower Hotline. Both channels enable anonymous reporting. Westpac’s Whistleblower Protection Officers are responsible for providing protections to whistleblowers who are concerned about potentially experiencing detrimental conduct because of speaking up. They also engage directly with whistleblowers to address risks of reprisal. Whistleblowers may raise a concern directly with a Whistleblower Protection Officer. The Westpac Group Speaking Up Policy requires that we investigate concerns in a confidential, fair and objective manner. If the investigation shows that wrongdoing occurred, we are committed to taking action, such as changing our processes and imposing consequences on those involved in wrongdoing. Outcomes may also involve reporting the matter to relevant authorities and regulators. The Board Audit Committee, in conjunction with the Board Risk Committee, oversees Westpac’s Whistleblower Program. Material whistleblower matters raised under the Westpac Group Speaking Up Policy are reported to the Board Risk Committee and may be escalated to the Board Audit Committee as appropriate.

204 WESTPAC GROUP 2025 ANNUAL REPORT CORPORATE GOVERNANCE SUSTAINABILITY We view sustainable and responsible business practices as important for our business and our stakeholders. Sustainability is about managing environmental and social risks and opportunities across our business in a way that seeks to balance the needs of our stakeholders – our customers, employees, suppliers, investors and the communities in which we operate. We aim to address the matters we believe are the most material for our business and our stakeholders, now and in the future. Environmental and social risks and opportunities continue to evolve so we seek to monitor these developments while aiming to embed sustainability into our business practices. We participate in a number of voluntary initiatives including the Global Reporting Initiative (GRI), the UN Global Compact and the International Sustainability Standards Board (ISSB) standards. We report on the most material sustainability topics, identified in our annual materiality assessment and aligned with the GRI standards, in our Annual Report and on our website. We are also focused on aligning our reporting with the new Australian Accounting Standards Board requirements for climate-related disclosure (AASB S2), which become mandatory for Westpac from our FY26 reporting year, as well as the Aotearoa New Zealand Climate Standards that have applied to our New Zealand operations since FY24. Sustainability governance and risk management disclosures are included in our Annual Report and our Sustainability Report, which are available on our website at www.westpac.com.au/about-westpac/investor-centre/annual-report/. Material exposure to sustainability risks and other categories of risks Westpac is exposed to environmental and social risks such as climate change risk. We seek to manage our material exposures to these risks, as well as other material risks we face, in accordance with our risk management strategy and frameworks. Further details about the risks we face, and how we seek to manage them, are in our 2025 Annual Report (see sections on 'Creating Value for the Community', 'Creating Value for the Environment' and 'Risk Management') and our 2025 Risk Factors. In addition, our Sustainability Report, our Human Rights Position Statement and Action Plan, and our Modern Slavery Statement are available on our website at www.westpac.com.au/about-westpac/sustainability/. RISK MANAGEMENT Westpac’s risk management framework comprises systems, structures, policies, processes and people that identify, measure, evaluate, monitor, report and control or mitigate sources of material risks. The Risk Management Strategy outlines this framework, Westpac’s material risks, and how they are managed. The Board, with the Board Risk Committee’s assistance, reviews the Risk Management Strategy and Board Risk Appetite Statement annually to satisfy itself that the risk management framework continues to be sound and that Westpac is operating within the risk appetite set by the Board. These reviews were conducted in the 2025 financial year. The Strategic review in the 2025 Annual Report provides more details on the risk management framework, including its structure based on the Three Lines of Defence model; management and the Board Risk Committee; actions taken to enhance risk management during the year; and emerging risks for Westpac. Risk Culture Westpac considers that a strong risk culture is essential for the Group’s risk management framework to operate effectively. Building and maintaining a strong risk culture is a continuing focus of the Board and will help support our ambition to be our customers' number one bank and partner through life. Westpac has embedded processes and tools to continue to improve risk culture, and track progress towards our goal of a risk culture that proactively identifies, manages and mitigates risks, learns from risk events and continuously anticipates new risks and opportunities. An ongoing Group-wide learning program provides an opportunity for employees to spend time on the specifics of risk management. Further information about this work is available in the Strategic review in our 2025 Annual Report. Three Lines of Defence (3LOD) We have adopted and continue to embed a 3LOD model which is designed to enable all our people to understand their own role and responsibilities in the active management of risk. Further information on the 3LOD model is available in the Strategic review section in our 2025 Annual Report.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 205 FINANCIAL REPORTING AND AUDIT Approach to financial reporting Our approach to financial reporting reflects three core principles: • that our financial reports present a true and fair view of our financial position and performance; • that our accounting methods comply with applicable accounting standards and policies; and • that our external auditor is independent and serves security holders’ interests. The Board, through the Board Audit Committee, has regard to Australian and international developments relevant to these principles when reviewing our practices. The Board delegates oversight responsibility for the integrity of financial statements and financial reporting systems to the Board Audit Committee. The Board Risk Committee provides relevant periodic assurances and reports (as appropriate) to the Board Audit Committee. Similarly, the Board delegates oversight responsibility for the preparation of remuneration reports and disclosures to the Board Remuneration Committee, which recommends remuneration reports and related disclosures, and provides relevant assurances, through the Board Audit Committee to the Board for approval. CEO and CFO assurance The Board receives regular reports from management about our financial condition and operational results. Before the Board approves the half year and full year financial statements, the CEO and the CFO declare to the Board that in all material respects: • Westpac’s financial records: – correctly record and explain its transactions, and financial position and performance; – enable true and fair financial statements to be prepared and audited; and – are retained for seven years after the transactions covered by the records are completed; • the financial statements and notes comply with applicable accounting standards; • the financial statements and notes give a true and fair view of Westpac’s financial position and performance; • (in relation to full year financial statements), the consolidated entity disclosure statement is true and correct; • any other matters that are prescribed by the Corporations Act 2001 (Cth) and regulations as they relate to the financial statements and notes are satisfied; and • the declarations above have been formed on the basis of a sound system of risk management and internal control, and that the system is operating effectively in all material respects in relation to financial reporting risks. The CEO and CFO have provided such statements for the financial year ended 30 September 2025. External auditor Our external auditor (for the 2025 financial year) is KPMG, appointed by shareholders at the 2024 AGM. Our KPMG lead audit partner is Ms Kim Lawry. The external auditor receives all Board Audit Committee and Board Risk Committee papers, attends all meetings of these committees and is available to Committee members at any time. The external auditor also attends the AGM to answer questions from shareholders regarding the conduct of its audit, the audit report and financial statements and its independence. The external auditor is required to confirm its independence and compliance with specified independence standards at our half and full financial year, however in practice it confirms its independence on a quarterly basis. We strictly govern our relationship with the external auditor, including restrictions on employment, business relationships, financial interests and use of our financial products by the external auditor. Periodically, the Board Audit Committee consults with the external auditor without the presence of management about internal controls over financial information, reporting and disclosure and the fullness and accuracy of the Group’s financial statements. The Board Audit Committee also meets with the Chief Audit Officer without other members of management being present. Engagement of the external auditor To avoid possible independence or conflict issues, our ‘Pre-approval of engagement of external auditor for audit and non-audit services’ policy (NAS Policy) prohibits the external auditor from carrying out certain types of non-audit services for Westpac. The NAS Policy also limits the extent to which the external auditor can perform other non-audit services. Use of the external auditor for any non-audit services must be assessed and approved in accordance with the pre-approval process set out in the NAS Policy. Group Audit (internal audit) Group Audit is the Third Line assurance function that provides the Board and management with independent and objective evaluation of the adequacy and effectiveness of the Group’s governance, risk management and internal controls. Group Audit is governed by a charter approved by the Board Audit Committee that sets out its purpose, role, scope and responsibilities. Group Audit’s activities conform with the Global Internal Audit Standards (GIAS), including the principles of Ethics and Professionalism. To safeguard the independence and standing of Group Audit, the Chief Audit Officer has a direct (functional) reporting line into the Board Audit Committee, through

Board Audit Committee dialogue with management, external audit and Group audit The Board Audit Committee maintains an ongoing dialogue with management, the external auditor and Group Audit, including regarding those matters that are likely to be designated as Key Audit Matters in the external auditor’s report. Key Audit Matters are those matters which, in the opinion of the external auditor, are of the most significance in their audit of the financial report. As part of its oversight responsibilities, the Board Audit Committee also conducts discussions with a wide range of internal and external stakeholders including: • the external auditor, about our major financial reporting risk exposures and the steps management has taken to monitor and control such exposures; • Group Audit and the external auditor concerning their reports regarding significant findings in the conduct of their audits, and overseeing that any issues identified are rectified by management in an appropriate and timely way or reported to the Board Risk Committee (with the Board Risk Committee overseeing management's response to rectifying those issues); • management and the external auditor concerning the half year and full year financial statements; • management and the external auditor regarding any correspondence with regulators or government agencies, and any published reports which raise material issues or could impact on matters regarding the Westpac Group’s financial statements or accounting policies; and • the Group General Counsel regarding any legal matters that may have a material impact on, or require disclosure in, the financial statements. MARKET DISCLOSURE AND SHAREHOLDER COMMUNICATION Verification of periodic corporate reports For periodic corporate reports released to the market which are not required to be audited or reviewed by our external auditor, we have verification and approval processes to support the integrity of the information disclosed. The process varies depending on the report and generally involves the individuals with responsibility for the information confirming to the best of their knowledge that the information is accurate and not misleading. The process may also involve review by internal subject matter experts (and as appropriate, our external advisers); and review by and confirmation from the individual responsible for the corporate report that it is appropriate for release. Such periodic corporate reports may also be required to be approved by the Disclosure Committee or the Disclosure Officer (or delegate) or the Board under our Market Disclosure Policy – as described below. Market disclosure We seek to provide our investors with equal, timely, accurate and balanced disclosure. Our Market Disclosure Policy is available on our website at www.westpac.com.au/about-westpac/westpac-group/ corporate-governance/principles-policies/. The policy provides a framework for how we manage our disclosure obligations and satisfy the disclosure requirements of the ASX, NZX, and other relevant offshore securities exchanges, as well as relevant securities and corporations legislation. Under our policy, and in accordance with our obligations, information that a reasonable person would expect to have a material effect on the price or value of our securities must immediately be disclosed via the ASX unless an exception applies under regulatory requirements. Certain disclosure decisions are the responsibility of the Board (for example, relating to matters of fundamental importance to the Group such as material transactions or material changes in strategic direction). For other decisions concerning potentially market sensitive information, our Disclosure Committee is responsible for determining whether matters should be disclosed publicly under the policy, and for assisting employees in understanding what information may require disclosure to the market on the basis that it is market sensitive. The Disclosure Committee is comprised of the Disclosure Officer (who is the CFO), the Group General Counsel and at least one of the following: the CEO, the Chief Risk Officer, the Group Executive, Customer & Corporate

Shareholder communication and participation We are committed to keeping shareholders fully informed about Westpac in compliance with our obligations – from our strategy, operations and performance, to our governance and sustainability approach. As part of our investor relations program – and consistent with our Market Disclosure Policy – we carry out a range of activities to facilitate two-way communication with shareholders, including: • providing relevant company information online via our Investor Centre on our website; • giving shareholders the option to receive information and communications electronically or via hard copy; • responding to shareholder queries directly via phone, email and mail; and • enabling shareholders to view major market briefings and maintaining that information in our Investor Centre. Our financial calendar in our Investor Centre lists all major market briefings and shareholder meetings. Announcements on these events may also be made on the ASX. Westpac seeks to facilitate shareholder participation at general meetings. We aim to choose a time and location that is convenient for shareholders. We provide explanatory notes in the Notice of Meeting to shareholders, and the AGM is also webcast live with a replay available for viewing in our Investor Centre. Westpac engages with shareholders and shareholder groups throughout the year to gather feedback and allow them to ask questions. This feedback assists the Group’s decision making and allows us to address any key themes in our reporting and/or at our meeting. Westpac intends to hold an in-person meeting this year. Shareholders unable to attend in person may view the meeting via a live webcast and ask questions online during the meeting. In addition, shareholders will also have the opportunity, prior to the AGM, to submit questions, lodge a direct vote or appoint a proxy, corporate representative or attorney to vote on a shareholder’s behalf at the AGM.

216 WESTPAC GROUP 2025 ANNUAL REPORT DIRECTORS' REPORT Operating and financial review Principal activities The principal activities of the Group during the financial year ended 30 September 2025 were the provision of financial services including lending, deposit taking, payments services, investment platforms, leasing finance, general finance, interest rate risk management and foreign exchange services. There have been no significant changes in the nature of the principal activities of the Group during 2025. Operations and financial performance Net profit for 2025 was $6,916 million, a decrease of 1% compared to 2024. The decrease in net profit reflects an increase in operating expenses partly offset by higher income and lower credit impairment charges. Basic earnings per share remained stable at 201.9 cents. The following is a summary of the movements in major line items in net profit for 2025 compared to 2024. Net interest income increased by $627 million or 3% driven by growth in average interest earning assets of 3% and stable net interest margin. Key movements in net interest income included: • Improved interest income from growth in average interest earning assets; and • Disciplined management of deposit funding costs in response to falling asset yields. Non-interest income was $169 million or 6% higher. The key movements included: • Favourable market movements on the value of financial instruments measured at fair value in 2025 of $38 million, compared to a loss of $24 million in 2024; • Higher wealth management income mainly due to volume growth of funds under administration; and • Improvements in transaction fee income, mainly resulting from higher line and guarantee fees. Operating expenses were $972 million or 9% higher. The key movements included: • Higher employee costs of $686 million mainly from restructuring costs and additional staffing attached to our UNITE program; and • A $181 million increase in technology services expenses from inflationary pressure and the impact of our UNITE program; and • A $110 million increase in amortisation and impairment of software assets from projects completed. Credit impairment charges of $424 million represented 5 basis points of average gross loans compared to 7 basis points in 2024. The decrease primarily reflected higher write-back and recoveries partly offset by higher charges from collective assessed exposures. The effective tax rate of 30.97% in 2025 was slightly higher than the Australian corporate tax rate of 30%, mainly due to non tax deductible hybrid instrument distributions. A review of the operations of the Group and its segments and their results for the financial year ended 30 September 2025 is set out in the Creating value for shareholders (pages 152- 159) section which form part of this Directors' report. Further information about our financial position and financial results is included in the Financial Report which forms part of this Directors' report. Dividends Westpac has announced a final ordinary dividend of 77 cents per Westpac ordinary share, totalling $2.6 billion. The dividend will be fully franked and will be paid on 19 December 2025. In 2025, an interim ordinary dividend of 76 cents per Westpac ordinary share totalling $2.6 billion was paid as a fully franked dividend on 27 June 2025 (2024: ordinary dividend of 75 cents and a special dividend of 15 cents per share totalling to $3.1 billion). For the year ended 30 September 2024, a fully franked final dividend of 76 cents per ordinary share totalling $2.6 billion was paid on 19 December 2024.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 217 Significant changes in state of affairs and events during and since the end of the 2025 financial year Significant changes in the state of affairs of the Group during the financial year ended 30 September 2025, or that have occurred since that date, were: • On 16 December 2024, Anthony Miller commenced as CEO and Managing Director. • Following approval by Westpac’s shareholders at the 2024 AGM on 13 December 2024, KPMG commenced as Westpac’s external auditor for the 2025 financial year. • Following completion of the Integrated Plan (IP) in December 2023 (required under the enforceable undertaking entered into with APRA in December 2020 in relation to our risk governance remediation), Westpac continued to focus on the sustainability and effectiveness of the IP uplifts via a transition phase. On 31 December 2024, we completed the transition phase, as confirmed by Promontory Australia (as Independent Reviewer) in February 2025. • On 15 October 2025, APRA announced its decision to lift the CEU and remove Westpac's remaining $500 million operational risk capital overlay. The removal of the $500 million capital overlay will mean Westpac’s Common Equity Tier 1 (CET1) capital ratio will increase by approximately 17 basis points, reflecting a reduction in risk weighted assets of $6,250 million. This change applied with immediate effect. For a discussion of these changes and other significant developments, please refer to Significant developments (pages 268-269) which forms part of this Directors' report. The Directors are not aware of any other matter or circumstance that has occurred since 30 September 2025 that has significantly affected or may significantly affect the operations of the Group, the results of these operations or the state of affairs of the Group in subsequent financial years. Business strategies, developments and expected results Our business strategies, prospects and likely major developments in the Group’s operations in future financial years and the expected results of those operations are discussed in the Strategic Review (pages 144- 272) and in Significant developments (pages 268-269) which form part of this Directors' report. Further information on our business strategies and prospects for future financial years and likely developments in our operations and the expected results of operations have not been included in this report because the Directors believe it would be likely to result in unreasonable prejudice to the Group. Risks to our financial performance, position and our operations Our financial position, our future financial results, our operations and the success of our strategy are subject to a range of risks. These risks are set out and discussed in the Risk Management section (pages 180-187) which forms part of the Directors' report. For additional information on risks relating to Westpac, refer to 2025 Risk Factors as disclosed on the ASX on the same date as this report.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 219 Indemnities and insurance Under the Westpac Constitution, unless it is forbidden or would be made void by statute, we indemnify any person who is or has been a Director or Company Secretary of Westpac and of each of our related bodies corporate (except related bodies corporate listed on a recognised stock exchange), any person who is or has been an employee of Westpac or our subsidiaries (except subsidiaries listed on a recognised stock exchange), and any person who is or has been acting as a responsible manager under the terms of an Australian Financial Services Licence of any of Westpac’s wholly-owned subsidiaries against every liability (other than a liability for legal costs) incurred by each such person in their capacity as director, company secretary, employee or responsible manager, as the case may be; and all legal costs incurred in defending or resisting (or otherwise in connection with) proceedings, whether civil or criminal or of an administrative or investigatory nature, in which the person becomes involved because of that capacity. Each of the Directors named in this Directors’ report and the Company Secretary of Westpac has the benefit of this indemnity. Consistent with shareholder approval at the 2000 Annual General Meeting, Westpac has entered into a Deed of Access and Indemnity with each of the Directors, which includes indemnification in identical terms to that provided in the Westpac Constitution. Westpac also executed a deed poll in September 2009 providing indemnification equivalent to that provided under the Westpac Constitution to individuals who are or have been acting as: • statutory officers (other than as a director) of Westpac; • directors and other statutory officers of wholly-owned subsidiaries of Westpac; and • directors and statutory officers of other nominated companies as approved by Westpac in accordance with the terms of the deed poll and Westpac’s Contractual Indemnity Policy. Some employees of Westpac’s related bodies corporate and responsible managers of Westpac and its related bodies corporate are also currently covered by a deed poll that was executed in November 2004, which is on similar terms to the September 2009 deed poll. The Westpac Constitution also permits us, to the extent permitted by law, to pay or agree to pay premiums for contracts insuring any person who is or has been a Director or Company Secretary of Westpac or any of its related bodies corporate against liability incurred by that person in that capacity, including a liability for legal costs, unless: • we are forbidden by statute to pay or agree to pay the premium; or • the contract would, if we paid the premium, be made void by statute. Under the September 2009 deed poll, Westpac also agrees to provide directors’ and officers’ liability insurance to Directors of Westpac and Directors of Westpac’s wholly-owned subsidiaries (except wholly-owned subsidiaries listed on a recognised stock exchange). For the year ended 30 September 2025, the Group has insurance cover which, in certain circumstances, will provide reimbursement for amounts which we have to pay under the indemnities set out above. That cover is subject to the terms and conditions of the relevant insurance, including but not limited to the limit of indemnity provided by the insurance. The insurance policies prohibit disclosure of the premium payable and the nature of the liabilities covered. Share rights outstanding As at the date of this report there are 4,376,980 share rights outstanding in relation to Westpac ordinary shares, held by 111 holders. The latest dates for exercise of the share rights range between 1 October 2026 and 2 December 2039. Holders of outstanding share rights in relation to Westpac ordinary shares do not have any rights under the share rights to participate in any share issue or interest of Westpac or any other body corporate.

Additional environmental disclosure is in our Climate Transition Plan which outlines how we are working to achieve our ambition to be a net-zero climate resilient bank and our Natural Capital Position Statement, which looks at how we assess the risks and opportunities associated with nature. This year, our Sustainability Report works towards aligning with Australia’s new Australian Sustainability Reporting Standard AASB S2. Westpac will need to fully comply with the new climate-related disclosure standard, AASB S2 in FY26. Westpac is also a climate reporting entity under the Financial Markets Conduct Act 2013 (NZ) and our 2025 Sustainability Report complies with the Aotearoa New Zealand Climate Standards (NZCS). In Australia we also report our scope 1 and 2 greenhouse gas emissions, energy consumption and production under the National Greenhouse and Energy Reporting (NGER) scheme for the period 1 July through 30 June each year. We are not aware of the Group incurring any material liability (including for rectification costs) under any environmental legislation. Human rights disclosure Our Human Rights Position Statement and Action Plan sets out Westpac Group's commitments and approach to respecting and advancing human rights. It outlines our approach to respecting human rights across our roles as a financial services provider, lender, purchaser of goods and services, employer, and supporter of communities, and integrates our position on child safeguarding. More information on our approach and the Group’s salient human rights issues can be found on the Human Rights section of our website and 2025 Sustainability Index and Datasheet. Under the Modern Slavery Act 2018 (Cth) and Modern Slavery Act 2015 (UK), Westpac is required to prepare an annual statement describing the risks of modern slavery across our operations and supply chain, and the actions taken to address the risks. Westpac published a joint statement for FY24 on behalf of itself and certain reporting entities that addressed the requirements of both Acts. For more information, see the Westpac Group’s 2024 Modern Slavery Statement, published in March 2025. We will release the Group’s FY25 Modern Slavery Statement in March 2026. Rounding of amounts Westpac is an entity to which ASIC Corporations Instrument 2016/191 dated 24 March 2016, relating to the rounding of amounts in directors’ reports and financial reports, applies. Pursuant to this Instrument, amounts in this Directors’ report and the accompanying financial report have been rounded to the nearest million dollars, unless indicated to the contrary.

222 WESTPAC GROUP 2025 ANNUAL REPORT DIRECTORS' REPORT Remuneration Report LETTER FROM THE CHAIR of the Board Remuneration Committee 2025 was a year of renewal, marked by refreshed leadership and a focus on positioning Westpac for long term growth. Dear shareholders, On behalf of the Board, I am pleased to present the 2025 Remuneration Report. Group performance We invested for the future while delivering sound financial results. Excluding Notable Items, NPAT achieved our target while ROTE was narrowly below target. Our costs were higher than planned, reflecting decisions made for the long term. Cost management will continue to be a priority. We gained market share in business lending while mortgages growth in Australia was at target. Overall, we delivered a total shareholder return of 29% for the financial year. We completed the CORE transition phase, resulting in APRA announcing the release of the remaining $500 million operational risk capital overlay, and made progress on the Group's transformation agenda. We delivered 88% of the 2025 UNITE priorities and delivered the first phases of the Westpac One and the BizEdge platforms. We have completed UNITE program discovery and made the decision to consolidate to a single deposit ledger. Overall, our customer experience needs to improve. Consumer NPS improved, with performance at target, but we have more work to do on Business NPS. Pleasingly, Westpac's relationship banking RSI was the highest in 10 years. Our people remain engaged and advocate for Westpac. Our Organisational Health Index score was 80 despite significant restructuring, exceeding our target of 77 and within the top quartile of workplaces globally. We have more to do to improve the representation of women in senior leadership. Executive performance and remuneration outcomes 2025 short term variable reward (STVR) The 2025 Group STVR Scorecard included four key priorities: Financial performance, Strategic execution, Serving customers, and People. This year we increased the weighting of financial performance from 45% to 50% and increased the weighting of the strategic execution category from 15% to 30%, including risk management which was a separate category in 2024. These changes recognise both feedback from investors and our completion of the CORE program. The Board assessed the CEO's STVR outcome at 85% of target. The CEO’s outcome was impacted by below threshold performance on the Group cost base measure. For Group Executives, STVR outcomes ranged from 92% to 102% of target, reflecting the differentiation of performance outcomes for their respective divisions and individual performance. 2022 long term variable reward (LTVR) The 2022 LTVR award was tested against a relative total shareholder return measure. Westpac delivered a total shareholder return of 77% over the four year performance period, resulting in a 62.5th percentile ranking relative to the financial services comparator group. As a result, the CEO and eligible Group Executives received 75% of their 2022 LTVR. It is pleasing that improved performance has led to a partial vesting of the LTVR. This demonstrates the alignment of our remuneration framework with the experience of shareholders. 2025 total target remuneration As foreshadowed in last year’s report, we increased the total target remuneration for four Group Executives. The increases recognised market comparisons and role accountabilities and were implemented for Carolyn McCann (10%), Catherine McGrath (6%), Michael Rowland (2%) and Ryan Zanin (4%). Carolyn McCann has since been appointed Chief Executive, Consumer and received a further 9% increase.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 223 CEO transition and executive leadership team renewal In December 2024, Anthony Miller (previously Chief Executive, Business & Wealth) succeeded Peter King as Westpac’s CEO. In his first year, Anthony has led the renewal of the Executive Team, advanced the implementation of the UNITE program and continued to reorient the organisation to be more customer focused. The new executive leadership team includes both internal and external appointments and the Board is confident we have the team to deliver on the strategy. Total target remuneration for new appointments So that the remuneration of our executives is appropriately positioned, each year we review internal and external benchmarks. Most of our new executive appointments, except for one, have been appointed on packages lower than their predecessors. Further details are included in the Summary of appointment and exit arrangements (page 224). Buy out awards for remuneration foregone In order to secure the talent required, we follow common market practice and provide buy out awards where necessary. When determining buy outs, our key principle is that the candidate should be no better or worse off and only compensated for remuneration foregone. Further details are included in the Summary of appointment and exit arrangements (page 224). Executive notice periods Following a market review we implemented changes to our executive employment agreement. We reduced the notice period required when an executive leaves Westpac from twelve months to six months. This is effective for all new executives that commenced from January 2025. Remuneration for our people Home finance manager pay framework In 2025, we increased the maximum variable reward opportunity for home finance manager roles from 50% to 80% of fixed pay. We made this change to remain competitive, attract talent and reward outperformance. We have made, and continue to make, refinements to the home finance manager pay framework so we remain tightly focused on risk and conduct management. Gender pay We are determined to pay our people fairly and equitably. We have pay equity for like-for-like roles and have reduced our median gender pay gap for total remuneration from 29.3% to 28.1% for the 2024-25 reporting year. There are a range of programs in place to improve gender diversity across levels, including our sponsorship and career development programs for women. There is more to do to ensure the gap continues to reduce. Refer to Creating value for our people (pages 166-169) for further information. Looking ahead 2026 short term variable reward The Board has set the 2026 Group STVR Scorecard to support the delivery of our priorities. We will maintain a 50% weighting to financial performance, with the remaining weightings of the Group STVR Scorecard focused on UNITE, customer, people, risk, and sustainability. In addition, we have added a leadership behaviours modifier in the Group Executive Scorecards aligned to our objectives to 'always deliver, safely', 'make an impact' and 'own it'. 2026 total target remuneration After reviewing market relativities, the Board determined that Catherine McGrath would receive an increase of 6% to her 2026 total target remuneration. There were no other increases as part of the annual remuneration review. CEO minimum shareholding requirement To strengthen the CEO's alignment with shareholders, the Board increased the CEO's minimum shareholding requirement from 200% to 300% of fixed remuneration. This change is effective from 1 October 2025 and Anthony will have a five year accumulation period from the date he was appointed as CEO. We are pleased that Anthony is well progressed in achieving the increased requirement. We hope you find the report informative and always welcome your feedback.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 229 3.3. 2025 Group STVR Scorecard The Group’s priorities are set out in the Group STVR Scorecard, which forms part of the CEO’s Scorecard. Common elements appear in Group Executive Scorecards together with individual objectives reflecting divisional measures. For 2025, we increased the financial performance weighting from 45% to 50% to emphasise our focus on delivering value. Risk measures were included within the ‘Strategic execution’ category, which was weighted at 30%. A summary of the performance assessment is provided below and is designed to be read over two pages. Where appropriate, individual measures have been assessed against a Threshold, Target and Stretch rating scale as outlined in the key. Each priority has also been assessed in totality using the same key. Key priority Measure Outcome Outcome commentary Key: Threshold 50-99% Stretch 101-125% Target 100% Performance assessment Financial performance (50%) Deliver current year financial performance (excluding Notable Items): • Net profit after tax -5% $6,971m +5% $6,972m result was at target. We delivered sound financial results against our targets. NPAT (excluding Notable Items) was at target and ROTE (excluding Notable Items) was narrowly below target, supported by a lower credit impairment charge and a higher than targeted net interest margin. Pre-provision profit was below target and our cost base was below threshold. We made decisions in the long term interest of Westpac which necessitated a period of elevated expense growth, including restructuring costs and an increase in UNITE investment spend. As a result, expenses were 3% adverse to target. We have a long-term focus on balance sheet strength with key metrics including the Common Equity Tier 1 capital ratio, Net Stable Funding Ratio, and Liquidity Coverage Ratio all above target operating ranges. Our strong balance sheet position provided us the capacity for dividends to be at the top end of the payout range. We have gained momentum in Australian business lending which increased to 1.37x of ADI financial system growth, which was at stretch. We maintained pricing disciplines and provided consistent service delivery in Australian mortgages with growth at 0.84x of ADI financial system, which was at target.

We have reduced customer losses from scams and the number of days to refund customers for fraud events, both achieving stretch performance. On demonstrating our sustainability and climate strategy, we increased our sustainable lending (total committed exposures and balances) to $39.4bn while we facilitated $6.3bn in bonds in 2025 aligned to our sustainable finance framework.

The value of deferred STVR is based on the number of restricted shares or share rights multiplied by the five day volume weighted average price (VWAP) up to and including the scheduled date of vesting for 2024 figures, and up to 1 October 2025 for the 2025 figures. The value of LTVR is based on the number of share rights multiplied by the five day VWAP up to and including the scheduled date of testing. Ryan Zanin’s 2022 LTVR award vesting outcome was 75% and the deferral period ends in February 2026.

The remaining 40% is delivered as cash. 1. The final value of equity received will depend on the share price at the time of vesting and the number of restricted shares or share rights that vest subject to performance conditions (where applicable), service conditions and remuneration adjustments. The value of equity differs from the disclosure in Section 7 which provides the annualised accounting value for unvested equity awards prepared in accordance with Australian Accounting Standards.

234 WESTPAC GROUP 2025 ANNUAL REPORT DIRECTORS' REPORT 2025 LTVR restricted rights pre-grant assessment We awarded the 2025 LTVR restricted rights, outlined in Section 3.5 above, following the pre-grant assessment which was completed in October 2024. The Board determined that the award be granted in full. Further details are available in the 2024 Remuneration Report. 2026 LTVR restricted rights pre-grant assessment The pre-grant assessment for the 2026 LTVR restricted rights was completed in October 2025. The Board determined that the 2026 LTVR restricted rights will be granted in full. The prudential soundness gate was satisfied by reviewing the key capital and liquidity ratios (CET1, LCR and NSFR). The ratios are all above minimum prudential requirements. Group risk culture maturity was assessed as Maintained. The Board had regard to the Group level risk-culture rating which was stable at ‘Systematic’ as well as improving results and positive momentum underlying the risk culture assessment. Other evidence points informing the CPS 220 Risk Management declaration included risk management framework maturity, root cause analyses, prudential attestations, audit and assurance findings and regulatory reviews. There were no significant risk outcomes or serious misconduct issues that arose that were not sufficiently addressed elsewhere. The LTVR restricted rights remain subject to the pre-vest assessment after the four year performance period ending 30 September 2029. The restricted rights also remain subject to remuneration adjustments during and after this period. Pre-grant assessment Outcome Step 1: Assessment Prudential soundness gate: Has Westpac remained safe and secure, taking into account capital position and liquidity? Met Group risk culture: Has Group risk culture maturity been maintained or improved, considering both executive actions or inactions? Maintained Significant risk outcomes: Have risk outcomes arisen that have a significant and material impact on the Group, not sufficiently addressed elsewhere? No adjustment Serious misconduct: Has Westpac suffered from a serious misconduct issue, not sufficiently addressed elsewhere? No adjustment Step 2: Consider Board discretion No adjustment Overall pre-grant assessment Grant in full

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 235 4. Remuneration governance 4.1. Group remuneration policy The Group remuneration policy sets out information in relation to remuneration design, arrangements and outcomes across Westpac. The policy is supported by an established governance structure, plans and frameworks. The policy supports our compliance with legal and regulatory requirements. Remuneration strategy Our remuneration strategy is to attract and retain talented employees. We reward them for achieving high performance and delivering superior long term results for our customers and shareholders. Remuneration principles • Promote our purpose, values and behaviours; • Align with our strategy and create sustainable shareholder value; • Offer market competitive and equitable pay; • Reward financial and non-financial performance, including customer outcomes and risk excellence; and • Reinforce our risk and conduct expectations. 4.2. Group remuneration governance Board The Board has overall accountability for the Remuneration Framework and its application. As set out in the Board Charter (and as supported by the Board Remuneration Committee Charter), without limiting its role the Board approves (following recommendation from the Board Remuneration Committee): the Group remuneration policy; the size of the annual Group variable reward pool; performance objectives and remuneration outcomes for the CEO; remuneration arrangements and outcomes for Accountable Persons, specified roles and any other person the Board determines; and equity-based plans. The Board has the absolute discretion to withdraw, defer or adjust aggregate and individual variable reward. Further detail is contained in the Board and Committee Charters which are available on Westpac’s website: https://www.westpac.com.au/about-westpac/westpac-group/corporate-governance/constitution-board/ Board Remuneration Committee The Board Remuneration Committee assists the Board to discharge its responsibility by overseeing the design, operation and monitoring of the Remuneration Framework. Members of the Board Remuneration Committee are independent Non-executive Directors. The Board and the Board Remuneration Committee have free and unfettered access to internal and external personnel in carrying out their respective duties. Further detail is contained in the Board Remuneration Committee Charter which is available on Westpac’s website: https://www.westpac.com.au/about-westpac/westpac-group/corporate-governance/constitution-board/ Management remuneration oversight Other Board Committees The Board and the Board Remuneration Committee receive support from internal groups and committees including, but not limited to, the Group Remuneration Oversight Committee and business-specific remuneration oversight committees. The Board Remuneration Committee seeks feedback from and considers matters raised by the CEO, Chief Risk Officer, the Board Audit Committee Chair and the Board Risk Committee Chair (as appropriate) with respect to remuneration outcomes, adjustments to remuneration in light of relevant matters and the alignment of remuneration with the risk management framework. Cross membership of the Board Remuneration Committee and the Board Risk Committee also supports alignment between risk and remuneration. Independent input is received from the Chief Risk Officer on risk, compliance and conduct matters that may need to be considered in remuneration outcomes. Remuneration advisor The Board or the Board Remuneration Committee may engage an independent remuneration advisor to directly provide specialist information on remuneration for key management personnel. Use of remuneration advisors: In 2025, the Board engaged EY to provide market benchmarking information on Group Executive remuneration and to conduct an independent effectiveness review of the remuneration framework as required by CPS 511. EY did not provide any remuneration recommendations as prescribed under the Corporations Act 2001 (Cth) (Corporations Act) in 2025.

236 WESTPAC GROUP 2025 ANNUAL REPORT DIRECTORS' REPORT 4.3. Our approach to remuneration adjustments Remuneration adjustment is one of the ways we reinforce our risk, compliance and conduct expectations. This includes downward adjustments for adverse outcomes, as well as upward adjustments to reward positive risk behaviours. An upward adjustment in variable reward may be considered for exceptional risk performance not already reflected in the delivery of agreed performance objectives. We have guidelines in place to support the consistent application of proportionate adjustments for significant risk, compliance or conduct matters. The graphic below provides an overview of our remuneration adjustment process and how it may potentially impact individual remuneration outcomes. Remuneration adjustment process BOARD DISCRETION Individual variable remuneration outcomes Reflects Westpac, divisional and individual performance outcomes (including risk and customer outcomes). May be adjusted downward (including to zero) for significant risk, compliance and conduct matters. Board discretion ¹ In year adjustments can include adjustments made through the STVR scorecard modifier and the LTVR pre-grant and pre-vest assessment. An assessment of severity of impact and individual accountability informs whether we trigger an adjustment. We apply judgement to consider whether the size of the adjustment is proportionate and fair. We take into consideration various facts specific to the matter including (but not limited to) the individual’s contribution and proximity to the direct and root causes of the matter, time in role, relative level of influence, findings of previous reviews and previous adjustments for related matters. The quantum of the remuneration adjustment increases with the severity of impact and individual accountability and influences the adjustment tool(s) used. Severity of impact based on: Customer People Reputation Regulation Financial Accountability Action or inaction of the individual Criteria We consider remuneration adjustments when there are significant adverse outcomes for the Group or its customers, beneficiaries, shareholders, counterparties or people related to: The criteria can be applied at an individual or collective level.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 237 5. Further detail on executive remuneration arrangements 5.1. Fixed remuneration The table below sets out the key design features of fixed remuneration. Fixed remuneration Purpose Provide market competitive remuneration reflecting role scope and accountabilities. Opportunity and benchmarking Set with reference to market benchmarks in the financial services industry and large corporates in Australia as appropriate. We also consider the size, responsibilities and complexity of the role, and the skills and experience of the executive. 5.2. Short term variable reward The table below sets out the key design features of the 2025 STVR. Short term variable reward Purpose Reward executives for delivering financial and non-financial annual objectives. Structure and delivery 50% of STVR is awarded in cash and 50% is deferred into equity in the form of restricted shares (or unhurdled share rights for the Group Executive based outside of Australia). One restricted share provides the holder with one Westpac ordinary share at no cost subject to trading restrictions until the time of vesting. One unhurdled share right entitles the holder to one ordinary share at the time of vesting with no exercise cost. Dividends are paid on restricted shares from the grant date. Target and maximum opportunity The target opportunity for the CEO and Group Executives is expressed as a percentage of fixed remuneration and is set at 75% of fixed remuneration (inclusive of superannuation). The target opportunity is set considering a range of factors including market competitiveness. Target STVR: awarded for the delivery of agreed targets for financial and non-financial measures. A reduced outcome can be determined for threshold performance. Maximum STVR: up to 125% of target STVR, awarded in circumstances where outcomes are achieved over and above target. Performance measures STVR awards are determined based on meeting minimum behaviour and risk and compliance gate openers, and performance against a scorecard designed to align with shareholder interests. The STVR Scorecard comprises three components: • Values and behaviours assessment: Demonstration of behaviours in line with Westpac's values of Helpful, Ethical, Leading change, Performing and Simple; • Focus areas: Performance is assessed against a balance of financial and non-financial measures that support the effective execution of Westpac’s strategy; and • Modifier: The modifier allows adjustment upwards or downwards (including to zero), for risk and reputation and people risk management considerations and any other matters as determined by the Board. Further information on the 2025 Group STVR Scorecard is provided in Section 3.3. Deferral period 50% of STVR is deferred into equity for a period of up to two years, which aligns executive remuneration with shareholder interests and acts as a retention mechanism. Deferred STVR vests in equal portions after one and two years, subject to service conditions and adjustment. Delayed vesting Refer to Section 5.4 for further information. Treatment of awards on cessation of employment Refer to Section 5.4 for further information. Remuneration adjustments Refer to Section 5.4 for further information.

238 WESTPAC GROUP 2025 ANNUAL REPORT DIRECTORS' REPORT 5.3. Long term variable reward LTVR is comprised of two components, which are equally weighted, comprising LTVR restricted rights and LTVR performance rights. The tables below set out the key design features of the 2025 LTVR award, as determined by the Board in October 2024. 5.3.1. Long term variable reward restricted rights for 2025 Long term variable reward restricted rights Purpose Reward executives for sustainable risk culture and for creating shareholder value over the long term. Structure and delivery 50% of the LTVR is awarded in restricted share rights (known as restricted rights). For the CEO, 50% vest after four years and 50% vest after five years. For Group Executives, 100% vest after four years. One restricted right provides the holder with one Westpac ordinary share at the time of vesting with no exercise cost. Executives receive dividend equivalent payments as outlined below. Award opportunity The value of LTVR restricted rights awarded to the CEO and Group Executives is expressed as a percentage of fixed remuneration. The value of LTVR restricted rights is set considering a range of factors including market competitiveness. The face value of the 2025 LTVR restricted rights opportunity for the CEO and Group Executives is 70% of fixed remuneration (inclusive of superannuation). Allocation methodology The number of restricted rights each executive receives will be determined by dividing the dollar value of the LTVR restricted rights award by the face value of a restricted right. The face value of a restricted right is the five day VWAP of Westpac shares up to the commencement of the performance period (which is 1 October 2024 for the 2025 LTVR grant). Performance condition The restricted rights are subject to performance conditions which are assessed prior to the grant and prior to vesting. These assessments are known as the pre-grant assessment and the pre-vest assessment. The assessment is focused on maintaining or improving Group risk culture. The assessment will be primarily based on the assessment of collective Group risk culture as part of the Board’s annual attestation to APRA required under Prudential Standard CPS 220 Risk Management, which is a multi factorial, evidence based process. A prudential soundness gate applies. The Board will also consider if there have been any significant risk outcomes or any serious misconduct that have not been sufficiently addressed through performance management or STVR outcomes. Step 1: Assessment of risk factors 1. Prudential soundness gate: Has Westpac remained safe and secure, taking into account capital position and liquidity? Prudential soundness is measured through the common equity tier 1 capital ratio, liquidity coverage ratio and the net stable funding ratio. 2. Group risk culture: Has Group risk culture maturity been maintained or improved, considering both executive actions or inactions? The risk culture assessment involves a series of inputs, a review process and a Board assessment of Group risk culture. 3. Significant risk outcomes: Have risk outcomes arisen that have a significant and material impact on the Group, not sufficiently addressed elsewhere? 4. Serious misconduct: Has Westpac suffered from a serious misconduct issue, not sufficiently addressed elsewhere? Step 2: Consider Board discretion Considerations to guide the application of discretion and the overall assessment include: • The materiality of the adverse impact on Westpac’s financial position, or reputation, or customers, or shareholders, or employees or regulatory standing. • Whether the outcome was specific to Westpac, the banking industry or the broader market. • The extent to which performance and reward outcomes are already impacted (e.g. through remuneration adjustments), at a collective or individual level. • Whether any adjustment should be made on a collective or individual basis. Given the focus on maintaining or improving Group risk culture over the performance period, adjustments are unlikely at the pre-grant assessment and any potential adjustment is more likely at the pre-vest assessment. Assessment of performance outcomes LTVR restricted rights are assessed against risk culture at grant and following a four year performance period. The assessment of performance includes an assessment of risk factors and considers Board discretion. Dividend equivalent payments Dividend equivalent payments are payable to the extent that LTVR vests. For LTVR restricted rights, these are accrued for the performance period and the further deferral period after the performance period (if applicable), and paid at the end of the deferral period. Dividend equivalent payments are calculated by multiplying the number of LTVR restricted rights eligible to vest by the declared dividend price on each respective record date during the applicable period. The calculation excludes franking credits. Exercise period Vested rights may be exercised up to a maximum of two years from the vesting date of the award and will be auto-exercised if not exercised within the period. The exercise price for the rights is zero. No re-testing There is no re-testing. Awards that have not vested after the performance period are lapsed. Early vesting Unvested awards may vest (unless prevented by law) before the performance test date in the event of a change of control in Westpac as determined at the discretion of the Board or where employment ceases due to death or disability. Delayed vesting Refer to Section 5.4 for further information. Treatment of awards on cessation of employment Refer to Section 5.4 for further information. Remuneration adjustments Refer to Section 5.4 for further information.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 239 5.3.2. Long term variable reward performance rights for 2025 Long term variable reward performance rights Purpose Reward executives for creating shareholder value over the long term. Structure and delivery 50% of the LTVR is awarded in performance share rights (known as performance rights) which vest after six years for the CEO and after five years for Group Executives. One performance right provides the holder with one Westpac ordinary share at the time of vesting with no exercise cost. Executives receive dividend equivalent payments as outlined below. Award opportunity The value of LTVR performance rights awarded to the CEO and Group Executives is expressed as a percentage of fixed remuneration. The value of LTVR performance rights is set considering a range of factors including market competitiveness. The face value of the 2025 LTVR performance rights opportunity for the CEO and Group Executives is 70% of fixed remuneration (inclusive of superannuation). Allocation methodology The number of performance rights each executive receives will be determined by dividing the dollar value of the LTVR performance rights award by the face value of a performance right. The face value of a performance right is the five day VWAP of Westpac shares up to the commencement of the performance period (which is 1 October 2024 for the 2025 LTVR grant). Performance condition LTVR performance rights are subject to an assessment of relative TSR against two comparator groups. The two comparator groups are equally weighted and tested independently against a percentile ranking vesting schedule as outlined below. The Board retains discretion to amend the comparator groups and determine the overall vesting outcome as appropriate. Relative TSR is a measure of the total return delivered to shareholders over the performance period assuming dividends are reinvested, relative to that of peers. The LTVR performance rights conditions aim to achieve long term growth in shareholder value and support alignment between executive reward and shareholder interests. Westpac’s TSR performance Indicative vesting percentage At the 75th percentile or higher 100% Between the median and the 75th percentile Pro-rata vesting between 50% and 100% At the median 50% Below the median 0% The banking comparator group of companies comprises ANZ Group Holdings Limited, Bank of Queensland Limited, Bendigo and Adelaide Bank Limited, Commonwealth Bank of Australia and National Australia Bank Limited. The general ASX comparator group comprises the 20 largest companies on the ASX by market capitalisation, excluding resource companies. The 20 companies are determined at the start of the performance period on 1 October 2024. The general ASX comparator group of companies comprises ANZ Group Holdings Limited, Aristocrat Leisure Limited, Brambles Limited, Coles Group Limited, Commonwealth Bank of Australia, CSL Limited, Goodman Group, James Hardie Industries PLC, Macquarie Group Limited, National Australia Bank Limited, QBE Insurance Group Limited, REA Group Ltd, ResMed Inc, Suncorp Group Limited, Telstra Group Limited, Transurban Group, Wesfarmers Limited, WiseTech Global Limited, Woolworths Group Limited and Xero Limited. In the event of a merger, acquisition or de-listing of any of the 20 companies, that company will be removed from the comparator group. Assessment of performance outcomes LTVR performance rights are subject to relative TSR performance following a four year performance period. The relative TSR result is calculated independently for external objectivity before being provided to the Board to determine the vesting outcome. The Board may exercise discretion in determining the final vesting outcome. Dividend equivalent payments Dividend equivalent payments are payable to the extent that LTVR vests. For LTVR performance rights, these are only accrued for the further deferral period after the performance period and paid at the end of the deferral period. Dividend equivalent payments are calculated by multiplying the number of LTVR performance rights eligible to vest by the declared dividend price on each respective record date during the applicable period. The calculation excludes franking credits.

240 WESTPAC GROUP 2025 ANNUAL REPORT DIRECTORS' REPORT 5.4. Common design features for variable reward Delayed vesting The Board has discretion (subject to law) to delay vesting of variable reward if the individual is under investigation for adverse risk or conduct events including misconduct, is the subject of or implicated in legal or regulatory proceedings, if the Board considers it reasonable to delay vesting, or if delayed vesting is otherwise required by law. Treatment of awards on cessation of employment Unvested variable reward is forfeited or lapsed where the CEO or a Group Executive resigns or otherwise leaves the Group (except for the reasons listed below) before vesting occurs unless the Board determines that some or all of the unvested variable reward should remain on foot. If the CEO or a Group Executive ceases employment because of death or total and permanent disability, all unvested variable reward immediately vests or becomes exercisable unless prevented by law. If the CEO or a Group Executive ceases employment because they retire, are retrenched or cease employment by agreed separation, unvested variable reward stays on foot subject to applicable performance conditions and subject to any adjustment determined by the Board. Remuneration adjustments The Board has discretion to adjust variable reward (including current year STVR) downwards, including to zero, in specified circumstances including serious misconduct, if serious circumstances or new information come to light which mean that in the Board’s view all or part of the award was not appropriate, or where required by law or prudential standards. The Board will typically apply the adjustment to unvested deferred STVR where an adjustment to current year STVR is considered insufficient or unavailable, followed by an adjustment to unvested LTVR where an adjustment to current and deferred STVR is considered insufficient or unavailable. Clawback may also apply to vested variable reward, to the extent legally permissible and practicable. Refer to Section 4.3 for further information on our approach to remuneration adjustments. 5.5. Acting Group Executive arrangements Carolyn Hoy, Megan Rutter and Peter Herbert (whilst in the Acting Chief Executive, Business & Wealth role) were appointed on differing remuneration arrangements due to the acting nature of their roles. STVR is delivered as 60% cash and 40% as deferred equity in the form of restricted shares vesting in equal portions after one and two years. Maximum STVR opportunity is 125% of target STVR. STVR awards are determined based on meeting minimum behaviour and risk and compliance gate openers, and performance is assessed against a scorecard designed to align with shareholder interests. LTVR is service based with a pre-grant risk assessment. LTVR is awarded in restricted shares vesting over four and five years to satisfy CPS 511 deferral requirements. STVR and LTVR are subject to service conditions and remuneration adjustments. Carolyn McCann commenced the year as Group Executive, Customer & Corporate Services. During the year, Carolyn was appointed to the role of Acting Chief Executive, Consumer and was then appointed permanently to the role of Chief Executive, Consumer. Carolyn remained on Group Executive remuneration arrangements throughout all of these roles.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 241 5.6. Executive minimum shareholding requirements and current compliance The CEO and Group Executives are required to build and maintain a significant Westpac shareholding to strengthen alignment with shareholder interests. LTVR restricted rights and LTVR performance rights are not included in the calculation of shareholdings until performance conditions are met. At 30 September 2025, the CEO and Group Executives comply with or are on track to meet the requirements. Aspect of the requirements Description Requirement level CEO: Two times fixed remuneration including superannuationa . Group Executives: One times fixed remuneration including superannuation. Sale restrictions Executives are restricted from selling vested equity, other than for the purpose of meeting tax obligations, as follows: • For LTVR awards granted from 1 October 2021 onwards, until the required shareholding level is met; and • For STVR awards, where the required shareholding level is not met at the end of the accumulation period. Accumulation period Within five years of 1 October 2022 (i.e. by 1 October 2027), or appointment to their role, whichever is later. The Board Remuneration Committee retains discretion to make adjustments in exceptional circumstances. Calculation of shareholdings Unvested LTVR (including restricted rights and performance rights) is not included in the calculation of shareholdings until performance conditions are met. Other shareholdings are recognised. This includes: • Shares held in an employee share plan (including deferred STVR); • Shares held outright in the individual’s name either solely or jointly with another person; and • Shares held in a family trust or a self-managed superannuation fund. a. The minimum shareholding requirement for the CEO will increase to three times fixed remuneration from 1 October 2025. 5.7. Hedging policy Participants in Westpac’s equity plans are prohibited from entering, either directly or indirectly, into hedging arrangements for unvested awards and vested awards subject to a holding lock. No financial products may be used to mitigate the risk associated with these awards. Any attempt to hedge awards will result in forfeiture and the Board may consider other disciplinary action. These restrictions satisfy the requirements of the Corporations Act which prohibits hedging of unvested awards. 5.8. Employment agreements The remuneration and other terms of employment for the CEO and Group Executives are formalised in their employment agreements. Each agreement provides for the payment of fixed remuneration (including superannuation contributions), variable reward and other benefits such as death and disablement insurance cover. The table below details the key terms including termination provisions of the employment agreements for the CEO and Group Executives. Term Conditions Duration of agreement Ongoing until notice given by either party. Notice (by the executive or the Group) to terminate employment Twelve months for Executives that commenced before January 2025. Six months for new Executives that commenced from January 2025.a In the event of redundancy, the greater of the relevant notice period or Westpac's general notice and severance entitlements applies. Termination payments on termination without causeb Deferred STVR (which may be awarded on a pro rata basis for the part year served) and unvested LTVR will be treated in accordance with the applicable equity plan rules, and will remain subject to remuneration adjustments if the award is retained. Termination for cause Occurs immediately for misconduct. Deferred STVR and LTVR is forfeited, noting the Board has discretion to determine otherwise. Post-employment restraints CEO: Twelve months non-compete and non-solicitation restraints. Group Executives: Six months non-compete and twelve months non-solicitation restraints. a. Payment in lieu of notice may in certain circumstances be approved by the Board for some or all of the notice period. b. The maximum aggregate liability for termination benefits in respect of notice periods for the CEO and Group Executives at 30 September 2025 was $11.2 million (2024: $12.5 million).

Fixed remuneration is the total cost of cash salary, salary sacrificed benefits and an accrual for annual leave. Superannuation in excess of the maximum contribution base that is paid as cash is also included. b. The cash STVR award is typically paid in December following the end of the financial year. c. Non-monetary benefits are determined on the basis of the cost to the Group (including associated FBT, where applicable) and may include annual health checks, provision of taxation advice, bank funded car parking, executive life insurance as well as relocation costs and travel allowances. d. Includes payments on termination or other contracted amounts for current KMP.

For Anthony Miller, the cash buy out arrangement was agreed on 25 March 2021 and the remaining 5% of the cash portion of the buy out was paid in 2025. For Kate Dee, the cash buy out arrangement was agreed on 5 September 2025 and is due to be paid in March 2026.

A portion of the restricted shares held by Anthony Miller, Kate Dee and Paul Fowler represents an allocation made to compensate them for remuneration foregone from their previous employer on resignation to join Westpac. For Paul Fowler, the allocation that vested during the year is being recognised as an expense over 12 months from Paul's commencement date to reflect a minimum service period. g. Share rights are amortised over the performance and the relevant service period. They are calculated based on the fair value at the grant date (being the invitation opt out date) of hurdled and unhurdled share rights granted during the financial year up to 30 September 2025. Fair value is calculated using an external valuation based on the invitation opt out date. The 2025 value for Catherine McGrath includes 29% attributed to deferred STVR awards. h.

Restricted rights and performance rights granted to the CEO are approved by shareholders at the Annual General Meeting each year. We do not grant options. We award deferred STVR in the form of restricted shares (or unhurdled share rights for KMP in New Zealand). 2024 deferred STVR was awarded on 27 December 2024 (based on the invitation opt out date) for the CEO and Group Executives. The deferral period commenced on 1 October 2024. 50% of the award will vest on 15 November 2025 and 50% will vest on 15 November 2026 (subject to service conditions and remuneration adjustments). b. 50% of the performance rights granted in 2021 vested in October 2024 when assessed against the relative TSR performance condition. 100% of the deferred STVR due to vest in 2024 vested at the end of the deferral period. For Anthony Miller, 9,676 of the 31,791 restricted shares that vested were in relation to a buy out award representing the remaining 8% of the total number of shares allocated for that award. For Paul Fowler, 22,700 of the 22,700 restricted shares that vested were in relation to a buy out award representing 27% of the total number of shares allocated for that award and the remaining portions of the award are due to vest through to May 2030. c. Vested share rights granted prior to September 2023 may be exercised up to a maximum of 15 years from their commencement date. Vested share rights granted after September 2023 may be exercised up to two years following the vesting date, otherwise the share rights will be auto-exercised at the end of the term. d. For performance rights and unhurdled share rights, the value granted represents the number of securities granted multiplied by the fair value per instrument as set out in the table in the sub-section titled ‘Overview of unvested equity awards’. For restricted shares and restricted rights, the value granted represents the number of shares or rights granted multiplied by the closing price of a Westpac ordinary share on the date the awards were granted. These values, which represent the full value of the equity-based awards made to the CEO and Group Executives in 2025, do not reconcile with the amount shown in the table in Section 7.2 which shows the amount amortised in the current year. The minimum total value of the grants for future financial years is zero and an estimate of the maximum possible total value in future financial years is the fair value, as shown above. e. The value of each share right exercised, forfeited or lapsed is calculated based on the closing price of a Westpac ordinary share on the date of exercise (or forfeiture or lapse). The overall values reflect forfeitures or lapses as a result of a failure to meet service or performance conditions. f. The information relates to the period the individual was a KMP. Refer to Section 2 for further details.

248 WESTPAC GROUP 2025 ANNUAL REPORT DIRECTORS' REPORT 7.4. Overview of unvested equity awards The table below outlines key details of unvested equity awards as at 30 September 2025 awarded to the CEO and Group Executives for KMP roles. All awards are subject to service conditions, performance conditions (where applicable), deferral periods and remuneration adjustments. Further details of the awards can be located in prior Annual Reports. Fair values Fair values are determined in accordance with the requirements of AASB 2 Share-based Payment. For STVR and LTVR restricted rights, the fair value is calculated using the closing price of the grant date, which for accounting purposes is the invitation opt out date. For LTVR performance rights and unhurdled share rights, fair values are independently calculated by PFS Consulting at the grant date (which is the invitation opt out date). For the LTVR performance rights, a Monte Carlo simulation pricing model is used. Allocation values The value granted to executives for remuneration purposes differs from the fair value used for accounting purposes. For STVR grants prior to 2024, the allocation is determined by dividing the dollar value of the STVR award by the five day VWAP up to the grant date. For STVR grants from 2024 onwards, the allocation is determined by dividing the dollar value of the STVR award by the five day VWAP up to Westpac's variable reward payment date each year which is typically in December each year. Refer to Section 5.2 for further details of STVR. For LTVR grants, the allocation is determined by dividing the dollar value of the LTVR awards by the face value of a share right. The face value of a share right is the five day VWAP up to the commencement of the performance period. Refer to Section 5.3 for further details of LTVR.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 253 Auditor Non-audit services We engage KPMG on assignments additional to their statutory audit duties where their expertise or experience with Westpac or a controlled entity is important. Details of the non-audit service amounts paid or payable for non-audit services provided by KPMG during the 2025 financial year and PricewaterhouseCoopers (PwC) during the 2024 financial year are set out in Note 33 (page 119) to the financial statements. KPMG also provides audit and non-audit services to non-consolidated entities, non-consolidated trusts of which a Westpac Group entity is trustee, manager or responsible entity and non-consolidated superannuation funds or pension funds. The fees in respect of these services were approximately $0.2 million in total to KPMG and $6.4 million to PwC (2024: $6.6 million to PwC). KPMG may also provide audit and non-audit services to other entities in which Westpac holds a minority interest and which are not consolidated. Westpac is not aware of the amount of any fees paid to KPMG by those entities. Westpac has a policy on engaging KPMG for audit and non-audit services, details of which are set out in its 2025 Corporate Governance Statement in the section ‘Engagement of the external auditor’. The Board has considered the position and, in accordance with the advice received from the Board Audit Committee, is satisfied that the provision of the non-audit services during 2025 by KPMG is compatible with the general standard of independence for auditors imposed by the Corporations Act. The Directors are satisfied, in accordance with advice received from the Board Audit Committee, that the provision of non-audit services by KPMG, as set out above, did not compromise the auditor independence requirements of the Corporations Act for the following reasons: • all non-audit services provided by KPMG for the year have been reviewed by the Board Audit Committee, which is of the view that they do not impact the impartiality and objectivity of KPMG; and • based on quarterly independence declarations made by KPMG to the Board Audit Committee during the year, none of the services undermine the general principles relating to auditor independence including reviewing or auditing KPMG’s own work, acting in a management or a decision-making capacity for the company, acting as advocate for the company or jointly sharing economic risk and rewards. The Directors’ Report is signed in accordance with a resolution of the Board of Directors.

254 WESTPAC GROUP 2025 ANNUAL REPORT RISK FACTORS Our business is subject to risks that can adversely impact our financial performance, financial condition and future performance. The 2025 Annual Report Annual Report sets out our approach to managing risks, major risk categories that could impact our business, as well as key focus areas. The 2025 Risk Factors provides investors and potential investors with further information in relation to our current and emerging risks, as well as potential consequences if those risks materialise. The content of the 2025 Risk Factors is current as of the publication date, but its relevance may be impacted by subsequent developments. Risks and risk management strategies are inherently dynamic, evolving alongside changes in the external environment, market conditions and organisational priorities. The risks and uncertainties described below are not exhaustive and can emerge together or in quick succession, uncorrelated with the below order. Additional risks and uncertainties that we are currently unaware of or deem immaterial, may also become important factors that affect us. If any of the following risks materialise, our business, prospects, reputation, financial performance or financial condition could be materially adversely affected, which may subsequently cause the price of our securities or the level of dividends to decline and, as a security holder, you could lose all, or part, of your investment. You should carefully consider the risks described (individually and in combination) and the other information in the 2025 Risk Factors and in the 2025 Annual Report and subsequent disclosures before investing in, or continuing to own, our securities. Risks relating to our business1 We have experienced, and could in the future experience, information security risks, including cyberattacks - Cyber risk - Cyber attacks - Operational risk - Information security risks - Data breaches - Third party risk Our operations depend on the secure processing, storage and transmission of information on our systems and those of external suppliers. Despite protective measures, including to protect the confidentiality, availability and integrity of our information, our information assets may face security breaches, unauthorised access, malware, social engineering, denial of service attacks, ransomware, destructive attacks, employee misconduct, human error or other external and internal threats. These could adversely impact our and others’ confidential information and system availability. Information security risks are heightened by factors such as new technologies, increased digitisation, larger volumes of sensitive data, sophisticated cyber crime, supply chain disruptions, remote and hybrid working, targeting of critical infrastructure providers, geopolitical tensions, terrorism, state sponsored attacks, and AI-enhanced cyberattacks (which can increase the speed, breadth, complexity and effectiveness of cyberattacks). These factors could compromise our information assets and disrupt operations for us, our customers, suppliers and counterparties. Adverse events such as data breaches, cyberattacks, espionage and errors (including human-related), are increasing in frequency and impact, potentially causing financial instability, reputational damage, service disruption, contagion risk, in addition to economic and non-economic losses to us, our customers, shareholders, suppliers, counterparties and others. Our protective systems and processes have not always been, and may not always be, effective and human error can occur. Westpac, our customers and other stakeholders could suffer losses from cyberattacks, information security breaches or ineffective cyber resilience. Consequences could be severe if customer data is being held in breach of legal or regulatory obligations and that data is compromised as part of an information security incident. We may not always predict, prevent or effectively respond to such incidents, or effectively respond to and/or rectify the resulting damage. Our suppliers, counterparties, and other parties involved in or who facilitate our activities, financial platforms and infrastructure as well as our customers’ suppliers and counterparties are also at risk, which could impact us. As cyberattacks increase globally, so does the likelihood of regulatory enforcement and legal actions, including class actions related to information security failures, misleading disclosures, or deficient responses to incidents. Consequences of attacks could include damage to technology infrastructure (including data centres), government intervention, service disruptions, loss of customers and market share, data loss, cyber extortion, customer remediation and/or compensation, breaches of the law or other obligations, vulnerability to fraud or scams, litigation, fines, and increased regulatory scrutiny or other enforcement action. 1.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 255 Such outcomes could negatively affect our business, prospects, reputation, financial performance or financial condition. As cyber threats evolve, we may need to allocate significant resources and incur additional costs to enhance our systems, address vulnerabilities or incidents and respond to regulatory changes. We could suffer losses due to geopolitical events - Geopolitical risks - Conflicts - Operational risk - Credit risk We, our customers and our suppliers operate businesses, engage in trade with and hold assets in different geographic locations. Significant risks subsist including from geopolitical instability, conflicts, trade tensions, tariffs, sanctions, social disruption, civil unrest, war, terrorist activity, acts of international hostility, and complicity with or inaction regarding certain types of crimes. Such events or the uncertainty related to the potential for such events are and could continue to directly and indirectly impact our and our customers’ operations, affect domestic and international economic stability and/or impact consumer and investor confidence, which in turn could disrupt industries, businesses, service providers and supply chains and ultimately adversely impact economic activity. Potential outcomes include material labour shortages, higher energy costs and commodity prices, volatility in markets, damage to property and disruptions where essential services, logistics and infrastructure are materially impacted. Such impacts could affect asset values and impact customers’ repayment ability, and our ability to recover amounts owing. All of these impacts could adversely affect our business, prospects, financial performance or financial condition. The current global landscape, marked by significant and prolonged conflicts, increasing protectionist policies (and uncertainties surrounding such policies) and heightened tensions, risks further intensifying these impacts . We could be adversely affected by legal or regulatory change - Compliance and conduct risk - Regulators' expectations - Legal and regulatory change - Fines, penalties, other costs and capital overlays We operate in a highly regulated industry with an environment of sustained legal and regulatory change and ongoing scrutiny of financial services providers. Our business, prospects, reputation, financial performance and financial condition have been, and could in the future be, adversely affected by domestic and international changes to laws, regulations, policies, supervisory activities, regulator expectations, and industry codes such as the Banking Code of Practice. Such changes may affect how we operate and have altered, and may in the future alter, the way we provide our products and services, sometimes requiring us to change, suspend or discontinue our offerings. Industry-wide reviews and inquiries could further reshape laws, regulations, policy or regulatory expectations. Past and potential effects of such reviews include limiting our flexibility, requiring us to incur substantial costs (e.g. system changes, incurring Compensation Scheme of Last Resort levies, liabilities related to scams, fraud or operational costs relating to scam management or other industry wide issues), absorbing specialist resources, impacting profitability and requiring us to retain additional capital, which impacts our ability to pursue strategic initiatives or implement other changes, resulting in us being unable to increase or maintain market share and/or creating pressure on margins and fees. A failure to manage legal or regulatory changes effectively and in the timeframes required has resulted, and could in the future result, in the Group not meeting its compliance obligations. It could also result in enforcement actions, penalties, fines, civil litigation, capital impacts, and ultimately loss of or variations to business licences. Frequent and large volumes of regulatory change also contribute to execution risk, as technology, systems and process updates may not always be successful in keeping pace and there is heightened risk of flaws, human error or unintended consequences. Managing these changes may require significant management attention, costs and resources, including the availability of skilled personnel, which may be limited. There is additional information on certain aspects of regulatory changes affecting the Group in the Significant Developments section and in the sections titled ‘Critical accounting assumptions and estimates’ and ‘Future developments’ in Note 1 to the financial statements in the 2025 Annual Report.

256 WESTPAC GROUP 2025 ANNUAL REPORT RISK FACTORS We have been and could be adversely affected by failing to comply with laws, regulations or regulatory policy - Compliance and conduct risk - Regulators' expectations - Legal and regulatory - Industry codes - Fines, penalties and capital overlays We are responsible for complying with all applicable legal and regulatory requirements and industry codes of practice in the jurisdictions where we operate or obtain funding. Our compliance and conduct risks are exacerbated by the complexity and volume of regulation, as well as ongoing regulatory change. These risks increase when there is ambiguity or multiple ways of interpreting our obligations and rights, conflicting laws between jurisdictions or regimes, or where there is limited industry consultation or a lack of regulatory guidance, particularly with respect to new or untested regulations. Our compliance and conduct management system, which is designed to mitigate these risks, has not always been, and may not always be, effective. Breakdowns have occurred, and may in the future occur due to factors such as poor judgement, flaws in the design or implementation of controls or processes, or the implementation of new measures. Such issues can lead to non-compliance (including failures to meet expectations or obligations to appropriately report or provide information to regulators or customers), potentially resulting in adverse outcomes for Westpac, our customers or other stakeholders. Ongoing reviews and change programs continue to identify compliance issues. Compliance and conduct risk has occurred, and could continue to occur, through the provision of products and services (including through our platforms) that may not meet legal or regulatory requirements, third party needs or expectations (including those of our customers, regulators or the market), especially for vulnerable customers, customers in hardship and indigenous customers. This risk has occurred, and could continue to occur, from deliberate, reckless, negligent, accidental or unintentional conduct of our employees, officers, contractors, agents, authorised representatives, credit representatives, trustees (including of our platforms) and/or external service providers, resulting in circumvention of, or inadequate implementation of, controls, processes (including monitoring), policies or procedures. This could occur through a failure to meet professional obligations (including fiduciary, suitability and responsible lending requirements), human error or weaknesses in risk culture, corporate governance or organisational culture or poor product design and implementation (including failing to adequately code or connect our systems with products, failing in whole or in part to consider customer needs or selling products and services outside of target markets). Inadequate supervision and oversight of our distribution channels can heighten these risks. Non-compliance by our people may negatively impact other employees, leading to outcomes including litigation and reputational damage. Additionally, third party conduct (e.g. where customers misrepresent their position on product applications and we have failed to identify it) may limit our recourse and regulatory outcomes may not be mitigated by third party culpability. These factors have resulted, and could continue to result, in poor customer outcomes (including for vulnerable customers and customers in hardship) such as inappropriate charging, failure to meet contractual, or compliance obligations (or to promptly detect, report and/or remedy non-compliance), and other outcomes including impacts which may compromise the integrity of the markets in which we operate or data we report, reputational damage, increased regulatory surveillance or investigation and employment disputes. We are currently subject to a number of investigations, reviews and industry inquiries by, and have and continue to respond to a number of requests from, domestic and international regulators including APRA, ASIC, the ATO, the ACCC, AUSTRAC, BCCC, ACMA, FINRA, AFCA, the OAIC, RBNZ, New Zealand Financial Markets Authority, New Zealand Commerce Commission, the Fair Work Ombudsman, the SEC, BaFin and BPNG’s Financial Analysis and Supervision Unit, involving significant resources and costs, potentially diverting specialist resources from other work. Regulatory reviews and investigations have, and may in the future, result in a regulator taking administrative or enforcement action against us and/or our representatives. Regulators have broad powers and may issue directions (e.g. for product design and distribution and remedial action), pursue civil or criminal proceedings, seek substantial fines and penalties, and other compliance or enforcement outcomes. These risks are heightened (and penalties have been and may be higher) where contraventions are not promptly detected or addressed, where we fail to meet our obligations (or the expectations of regulators), where there are patterns of behaviour indicating systemic conduct or where there has been an awareness of contraventions, especially in areas of heightened regulatory focus, such as vulnerable customers, customers in hardship and indigenous customers. Additionally, regulatory investigations may lead to adverse findings against directors and management, including potential disqualification. The resources allocated to these reviews and investigations can impede other activities, including change and remediation programs. APRA can require, and has required, us to hold additional capital either through a capital overlay or higher risk weighted assets (including in response to a failure to comply with prudential standards and/or expectations in relation to, for example, stress testing and liquidity management). Capital overlays could have an adverse impact on our financial performance.

GRAPHIC

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 257 The evolving political and regulatory landscape has seen (and may continue to see) expansion of regulators’ powers, materially increased civil penalties and fines and increased criminal prosecutions against institutions and/or their employees and representatives (including where there is no fault element). This could also result in reputational damage and impact the willingness of customers, investors and other stakeholders to deal with us. Given our size and scale of activities, a failure by us may result in multiple contraventions, which could lead to significant penalties, remedial action and other consequences (e.g. regulatory damage). Regulatory investigations or actions commenced against the Group have exposed, and may in the future expose, the Group to an increased risk of litigation brought by third parties (including through class action proceedings), which may require us to pay (sometimes substantial) compensation to third parties and/or to undertake further remediation activities. Market developments suggest there is an expanding scope for potential claims, including in relation to cyber incidents, financial crime and ESG issues. We have incurred significant remediation costs on a number of occasions (including compensation payments and costs of correcting issues) and new issues may arise requiring remediation. We have faced, and may continue to face, challenges in effectively and reliably scoping, quantifying and implementing remediation activities (whether or not such activities are prompted by a regulator), including determining how to compensate impacted parties properly, fairly and in a timely way. Investigation of the underlying issue may be impeded due to the passage of time, technical system constraints, or inadequacy of records. Delays in remediation may occur due to factors such as the number of affected parties and their responsiveness, ongoing investigations or litigation, and regulatory requirements. Remediation programs may not prevent regulatory action or investigations, litigation or other proceedings from being pursued, or sanctions being imposed. Regulatory investigations, inquiries, litigation, fines, penalties, infringement notices, disclosures, revocation, suspension or variation of conditions of regulatory licences or other enforcement or administrative action or agreements (such as enforceable undertakings) have and could, either individually or in aggregate with other regulatory action, adversely affect our business, prospects, reputation, financial performance or financial condition and increase class action risk. There is additional information on certain regulatory and other matters that may affect the Group in the Significant Developments section and in Note 25 to the financial statements in the 2025 Annual Report. We have suffered, and in the future could suffer, losses and be adversely affected by the failure to implement effective risk management - Risk management - Controls and processes - Risk culture - Risk governance - Fines, penalties Our risk management framework has not always been, and may not in the future be, fully effective. Resources allocated to identifying, measuring, evaluating, monitoring, reporting, controlling or mitigating material risks may sometimes be inadequate. This may arise due to inadequacies in the design of the framework or key risk management policies, controls and processes, the design or operation of our remuneration structures and consequence management processes, technology failures, our corporate structure, incomplete implementation or embedment, or failure by our people (including contractors, agents, authorised representatives and credit representatives) to comply with or properly implement our policies and processes. The potential for these types of failings is heightened if we lack sufficiently skilled, trained or qualified personnel or capacity, including people, processes and technology, to appropriately manage risks. Although we periodically review our risk management framework to determine if it remains appropriate, all risk management frameworks have inherent limitations (and may also be ineffective because of weaknesses in risk culture or governance), and some risks may exist or emerge that we have not anticipated or identified. For example, where there is a lack of awareness of our policies, controls and processes or where they are not adequately complied with, monitored, audited or enforced. This may result in poor decision-making or risk and control weaknesses not being identified, escalated or acted upon. Risks are measured and monitored against our risk appetite, and when outside of appetite, we aim to take steps to bring such risks back into appetite, including framework and policy design improvements. However, bringing risks back within appetite may be delayed or ineffective, due to factors including complexity, information technology system enhancement delays, staffing constraints (including where staff are occupied by other regulatory change or remediation projects), operational failures or external factors beyond our control, resulting in certain risks remaining outside of appetite for periods of time. If any of our governance or risk management processes and procedures prove ineffective or inadequate or are not appropriately implemented or we fail to bring risks into appetite, we may face sustained or increased regulatory scrutiny and action. While a stronger risk culture fosters early self-identification and remediation, it may also highlight concerns that trigger further regulatory action. This may result in financial losses, additional capital requirements, compliance breaches, fines, reputational damage, and/or significant remediation, which could adversely affect our business, prospects, financial performance or financial condition.

258 WESTPAC GROUP 2025 ANNUAL REPORT RISK FACTORS We could suffer losses due to technology failures - Operational risk - Information and technology - Change management - Technology failure - UNITE program - Outages Maintaining the reliability, availability, integrity, confidentiality, security and resilience of our information and technology is crucial to our business. Despite existing processes to preserve, monitor and facilitate the availability of and recovery of, our systems, there is a risk that our information and technology systems may be inadequate, could be compromised, fail to operate properly or result in outages, including from events wholly or partially beyond our control. A technology deficiency or failure could lead to failures to meet contractual, legal or compliance obligations (such as a requirement to issue communications, retain records and/or data for a certain period, or to destroy records and/or data after a certain period, or other risk management, privacy, business continuity management or outsourcing obligations). Our stakeholders, including employees and customers may be adversely affected, including by being unable to access or be covered by our or a third party’s products or services (or being inappropriately charged for them), as a result of systems failures, privacy breaches, or the loss of personal data. This could result in business disruption, reputational damage, financial loss, remediation costs, regulatory investigations and/or action, or others commencing litigation. Technology issues in the financial sector can also affect multiple institutions, meaning we could impact, or be impacted by, other institutions. The use of legacy systems, as well as work underway to uplift our technological capabilities, may heighten transfer risks, the risk of a technology failure, change management issues and the risk of non-compliance with our regulatory obligations or poor customer outcomes. Projects aimed at simplifying/streamlining our systems (including our UNITE program) will require significant resources (including specialist expertise) and incur costs. These risks may be heightened while those projects are being undertaken, or post-implementation where there are unanticipated outcomes or impacts. These projects may also not be completed on time, may not deliver the expected benefits or may require further resources or funding than anticipated. The success of such projects relies in part on having robust governance arrangements and appropriate oversight at Board and senior executive level. Shortcomings in these areas could elevate the risk of regulatory non-compliance, poor customer outcomes, delays, increased costs or demand on resources. Failure to regularly renew and enhance our technology to deliver new products and services, comply with regulatory obligations and ongoing regulatory changes, improve automation of systems and controls, meet our customers’ and regulators’ expectations, or to effectively implement new technology projects, could result in cost and time overruns, technology failures (including due to human error in implementation), reduced productivity, outages, operational failures or instability, compliance failures, reputational damage and/or loss of market share. Climate change and other sustainability factors such as human rights and natural capital may have adverse effects on our business - Climate and nature risks - Physical and transition risks - Social and human rights risks - Credit risk - Operational risk - Reputational and sustainability risk - Compliance and conduct risks Climate and other sustainability-related risks have had and are likely to have adverse effects on us, our customers, external suppliers, and the communities in which we operate. Managing these risks is challenging given significant uncertainties in modelling and impact assessment. Climate related risks may manifest as physical risks, transition risks or liability risks. Physical risks include direct risks to us, our customers, suppliers and other stakeholders. These risks could arise from increases and variability in temperatures, precipitation changes, rising sea levels, loss of natural capital or biodiversity loss, and more severe and frequent climatic events, including fires, storms, floods and droughts. Such events could also increase human rights risk and/or increase customer vulnerability. Impacts may arise through damage, disruption or changes to business activities, operations, asset values and insurability of assets (or insurance availability/affordability), resulting in higher costs and/or reduced revenues to ourselves or customers. In turn, impacts on customers could lead to higher impairment charges in our lending portfolio. Transition risks may arise through the transition to a lower carbon economy, which in turn could impact Westpac through changes such as in consumer behaviour and market sentiment. These risks may emerge gradually and orderly, or abruptly and disorderly, or a combination of both. Impacts could result from climate change mitigation

GRAPHIC

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 259 efforts, the obsolescence of certain businesses due to the energy transition, changes in investor appetite, shifting customer preferences, technology developments and regulatory changes. Such risks could also emerge through lending to customers facing reduced revenues, asset devaluation and rising costs, thereby increasing our credit risk. Additionally, Westpac may be impacted by transition risks, and from adverse effects to the broader economy including as they relate to interest rates, inflation and growth (or lack thereof). Our ambition to become a net-zero, climate resilient bank, has led and will continue to lead to changes in policies and processes which may pose execution risk. Our ability to meet our ambition and targets depends partly on the broader economy’s orderly transition to net-zero, which may be impacted by external factors including (but not limited to) government policies, investment levels, electricity grid capacity, and constraints in the development and supply of technology, infrastructure and skilled labour. Our transition efforts, including to meet our targets and commitments, may also be impacted by the challenges faced by customers in executing their transition plans. Natural capital loss, referring to the depletion of renewable and non-renewable natural resources that combine to yield a flow of benefits to people, poses a risk to us. This risk emerges primarily through our exposure to customers that are materially dependent on or may impact natural resources. This loss can contribute to, and be accelerated by, climate change. Increasing recognition and response to this risk also create heightened regulatory and stakeholder expectations on Westpac. We may be exposed to social and human rights risks through our products and services, operations and supply chain. Failure to identify and manage these risks may cause, contribute to, or be directly linked to adverse social and human rights impacts. This includes the risk that we provide services to, or rely on services provided by, parties involved in human rights abuses or criminal activity. There is also the potential exploitation of our platforms and products for illicit purposes. Our ability to identify, assess, and mitigate these risks may be constrained by a range of factors including the increasing sophistication of perpetrators. Data used to assess and manage climate, and other sustainability-related risks continues to mature. Reliance on third party data (which may not be sufficiently available or reliable), may affect our decision making, target setting and reporting, and affect our ability to meet our targets and commitments. Associated risks may increase where disclosure of additional data is required by mandatory reporting. Actual or perceived failure to adapt our strategy, governance, procedures, systems and/or controls to manage or disclose climate and other sustainability-related risks and opportunities (including, for example, perceived misstatement of, or failure to adequately implement or meet, sustainability claims, commitments and/or targets) may give rise to business, reputational, legal and regulatory risks. This includes financial and credit risks that may impact our profitability and outlook, and the risk of regulatory action or litigation (including class actions) against us and/or our customers. We may also be subject, from time to time, to legal and business challenges due to actions instituted by activist or other groups. For example, our financing of businesses that are perceived to be more correlated with climate-related risks and/or that are considered not to be managing these issues responsibly have received feedback from some stakeholders and attracted scrutiny from activists. Scrutiny from regulators, shareholders, activists and other stakeholders on climate-related risk management practices, lending policies, targets and commitments, and other sustainability products, claims and marketing practices will likely remain high. Applicable legal and regulatory regimes, policies, and reporting and other standards are also evolving. For example, in Australia and New Zealand, mandatory climate reporting has been introduced, and there is an increased compliance and enforcement focus by ASIC and the ACCC on a range of issues related to sustainability and sustainable finance, along with the monitoring/investigation of related claims. All of this increases compliance, legal and regulatory risks, and costs. For further detail on the identification, assessment and management of these risks, please refer to the 2025 Sustainability Report, and the Creating Value for the Community, Creating Value for the Environment and Risk Management sections of the 2025 Annual Report. The failure to comply with financial crime obligations has had, and could have further, adverse effects on our business and reputation - Financial crime risk - Bribery and corruption - Tax evasion - Money laundering and terrorism financing - Economic and trade sanctions The Group is subject to a range of financial crime laws across its jurisdictions, including anti-money laundering and counter-terrorism financing (AML/CTF), anti-bribery and corruption, economic and trade sanctions and tax transparency (collectively, Financial Crime Laws). Financial Crime Laws are complex and impose a diverse range of obligations elevating regulatory, operational and compliance risks. In certain jurisdictions (e.g. the Pacific region), financial crime risks are elevated beyond the Group’s risk appetite requiring an appropriate action plan to reduce risk, and to return within appetite.

GRAPHIC

260 WESTPAC GROUP 2025 ANNUAL REPORT RISK FACTORS The Group must comply with a range of reporting obligations under the Financial Crime Laws, including international funds transfer instructions, threshold transaction reports, suspicious matter reports, Foreign Account Tax Compliance Act (FATCA) and Common Reporting Standard (CRS) reports. The Group must also ensure that we know who our customers are and that we have appropriate ongoing customer due diligence in place. The failure to comply with Financial Crime Laws has had, and in the future could potentially have, adverse impacts for the Group. The Group operates in a constantly evolving landscape, particularly with ongoing legislative reform impacting Financial Crime Laws, emergence of new payment technologies, increased regulatory focus on digital assets, and increasing use of economic and trade sanctions to manage issues of international concern. These developments may require updates to the Group’s systems, policies, processes and controls to manage emerging financial crime risks for the Group, including scams, fraud and technology-enabled crime. The Australian AML/CTF reforms, due to their scale and complexity, will require a multi-year implementation program involving complex technology, policy and control framework updates. The Group is actively engaging with AUSTRAC and is progressing the development of a phased implementation plan. However, implementation risk remains elevated due to the breadth of change and complexity involved. The industry (including Westpac) has challenges meeting the legislation’s effective date of 31 March 2026. Notwithstanding AUSTRAC’s acknowledgement of this and its published regulatory expectations noting that AUSTRAC does not expect immediate compliance, there is a risk that our implementation program or timeframes will not be adequate. Compliance with financial crime obligations remains a regulatory priority. Regulators globally continue to investigate and take enforcement actions for identified non-compliance, often seeking significant penalties. Given the scale and complexity of the Group’s operations, undetected failures or ineffective implementation, monitoring or remediation of a system, policy, process or control (including a regulatory reporting obligation) has resulted, and could in the future result, in a significant number of breaches of AML/CTF or other Financial Crime Laws, which could lead to significant financial penalties and other adverse impacts for the Group, such as reputational damage and litigation risk. While the Group has systems, policies, processes and controls in place designed to manage its financial crime obligations (including reporting obligations), these have not always been, and may not in the future always be, effective, due to reasons such as control deficiencies, technology failures or changes in financial crime risks or typologies. Our analysis, reviews and regulatory feedback, have highlighted that our systems, policies, processes and controls are not always operating satisfactorily in a number of respects and require improvement. The Group continues to have an increased focus on financial crime risk management and, as such, further issues requiring attention have been identified and may continue to emerge. Although the Group provides updates to various regulators on its remediation and other program activities, there is no assurance that those or other regulators will agree that its remediation and program update activities will be adequate or effectively enhance the Group’s compliance programs. Failure to comply with financial crime obligations has resulted, and could in the future result, in significant regulatory enforcement actions, reputational risks and other consequences as detailed in other sections of the 2025 Risk Factors. There is additional information on financial crime matters in the Significant Developments section in the 2025 Annual Report. Reputational damage has harmed, and could in the future harm, our business and prospects - Reputational and sustainability risk - Negative customer outcomes We face reputational risk where our plans, processes, performance and behaviours differ from the expectations, beliefs and perceptions of our stakeholders. Our actions, inactions or associations (or those of our customers, employees, suppliers, contractors, agents, authorised representatives, credit representatives, joint-venture partners, strategic partners or other counterparties) could result in reputational damage when they cause, or are perceived to cause, a negative outcome for customers, shareholders, the community or other stakeholders. This could arise from, for example, failure or perceived failure to adequately monitor, prevent or respond to community, environmental, social and ethical issues or expectations or failure to comply with regulatory requirements or expectations. We are also exposed to contagion risk from incidents in (or affecting) other financial institutions and/or the financial sector more broadly (e.g. issues affecting the cash-in-transit industry and the potential for disruption to the availability of cash, as well as flow on consequences including runs on cash) as well as from others whom we may have relationships with. Failure, or perceived failure, to address issues that could or do give rise to reputational risk, has created, and could in the future create, additional legal risk, including regulatory investigations, regulatory enforcement actions, fines and penalties or litigation or other actions brought by third parties (including class actions), and the requirement to remediate and compensate customers, including prospective customers, investors and the market. It could also result in losing customers or restricting our ability to efficiently access capital markets. This could adversely affect our business, prospects, financial performance or financial condition.

GRAPHIC

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 261 We have and could suffer losses due to litigation - Compliance and conduct risk - Enforcement action - Litigation - Class actions - Substantial fines and penalties Litigation has been, and could in the future be, commenced against us by a range of plaintiffs, such as customers, shareholders, employees, suppliers, counterparties, activists, receivers and regulators and may, either individually or in aggregate, adversely affect the Group’s business, operations, prospects, reputation or financial condition. There could be a range of reasons for litigation, including allegations relating to failure to comply with contractual, legal or regulatory requirements. Recently, there has been an increase in class action proceedings in the broader market, many of which have resulted in significant monetary settlements. The risk of class actions has been heightened by a number of factors, including regulatory enforcement actions and willingness by regulators to commence proceedings, increased regulatory investigations and inquiries, media scrutiny, increased prospect of regulatory reforms (including those that may eliminate any actual or perceived barriers to such litigation), and the growth of third party litigation funding. Class actions commenced against competitors could also lead to similar proceedings against us and may also impact attitudes of counterparties to Westpac proceedings or Westpac’s standing more broadly. There has also been an increase in proceedings related to third party scams and fraud activity, and the bank has been and may be joined to such proceedings, and an increase in shareholder derivative actions. Activism strategies directed at financial institutions, particularly related to climate change, sustainability, diversity equity and inclusion initiatives and energy transition, have also increased globally in recent years. These strategies may involve litigation to highlight issues, enforce legal or regulatory standards, or influence the target’s operations and activities. We are currently, and may continue to be, exposed to such litigation and/or activist strategies. Litigation is subject to many uncertainties, and the outcome may not be predicted accurately. Furthermore, the Group’s ability to respond to and defend litigation may be adversely affected by inadequate record keeping. The Group’s ability to settle litigation on reasonable terms will be affected by attitudes of counterparties. Costs will be incurred associated with managing, responding to and/or defending litigation. Depending on the outcome of any litigation, the Group has been, and may in the future be, required to comply with broad court orders, including compliance orders, adverse publicity orders, enforcement orders or otherwise pay significant damages, fines, penalties or legal costs. The actual amount paid following a settlement or determination by a Court for any legal proceedings may be materially higher or lower than any relevant provision (where applicable) or that any contingent liability may be larger than anticipated. There is also a risk that additional litigation or contingent liabilities arise, all of which could adversely affect our business, prospects, reputation, financial performance or financial condition. There is additional information on certain legal proceedings that may affect the Group in Note 25 to the financial statements in the 2025 Annual Report. We are exposed to adverse funding market conditions - Market risk - Volatility and disruption - Funding and liquidity risk - Credit risk We rely on deposits and global funding markets to fund our business and source liquidity. Our funding costs are subject to funding market and general economic and geopolitical conditions, in addition to our credit profile. Funding market conditions, and the behaviour of market participants, can shift significantly over very short periods of time, resulting in extreme volatility, disruption and decreased liquidity. The main risks we face relate to reduced market confidence, market access, appetite for exposure to Westpac; increased cost of funding; and impacts from deterioration in macroeconomic conditions. Additionally, shifts in investment preferences could result in deposit withdrawals, increasing our reliance on other funding sources. These other sources may offer lower levels of liquidity at higher costs. If market conditions deteriorate due to economic, political, regulatory, or other reasons (including those idiosyncratic to Westpac), there may be a loss of confidence in bank deposits, leading to unexpected withdrawals. These events can transpire quickly and be exacerbated by information transmission on social media. This could increase funding costs, constrain our liquidity, funding and lending activities and threaten our financial solvency. In such events, even robust levels of capital may not be sufficient to safeguard Westpac against detrimental loss of funding. If our current sources of funding become insufficient, we may need to seek alternatives, subject to market conditions, our credit ratings, reputation and confidence issues, and market capacity. These alternatives may be more expensive

262 WESTPAC GROUP 2025 ANNUAL REPORT RISK FACTORS or on unfavourable terms. If we are unable to source appropriate funding, we may be forced to reduce or suspend business activities (e.g. lending) or operate with smaller liquidity buffers. If we are unable to source funding or generate liquidity for an extended period, we may not be able to pay our debts as and when they fall due or meet other contractual obligations. These outcomes may adversely affect our financial performance, liquidity, capital resources or financial condition. We also enter into collateralised derivative obligations, which may require us to post additional collateral based on market movements. This has the potential to adversely affect our liquidity or ability to use derivatives to hedge interest rate, currency and other financial risks. We could be adversely affected by the risk of inadequate capital levels - Capital adequacy - Capital risk - Regulatory capital requirements The Group is subject to the risk of an inadequate level or composition of capital to support business activities, meet regulatory capital requirements under normal or stressed conditions, and to maintain our solvency. Even robust levels of capital may not be sufficient to ensure our ongoing sustainability in the event of a bank run, where depositors quickly withdraw funds because of concerns about bank failure. Our capital levels are determined by regulation and risk appetite and informed by stress testing. We establish buffers on regulatory requirements to maintain capital adequacy during stressed periods by considering factors such as our balance sheet, forecasts, portfolio mix, potential capital headwinds (including real estate valuations, inflation and rising interest rates) and stressed outcomes. Stress testing models and assumptions may or may not accurately predict the nature and magnitude of particular stress events. The macroeconomic environment, stressed conditions and/or regulatory framework could result in a material increase to risk weighted assets, impact our capital adequacy, trigger capital distribution constraints, threaten our financial viability and/or require a highly dilutive capital raise. Capital distribution constraints apply when an ADI’s CET1 Capital ratio is within the prudential capital buffer range (consisting of the Capital Conservation Buffer plus any Countercyclical Capital Buffer). Such constraints could impact future dividends and distributions on Additional Tier 1 (AT1) capital instruments, noting APRA’s intention to phase out AT1 capital instruments effective 1 January 2027. Should AT1 and Tier 2 capital securities that we have issued be converted into ordinary shares (for example where our CET1 ratio falls below a certain level or APRA determines we would become non-viable without conversion of capital instruments or equivalent support), this could significantly dilute the value of existing ordinary shares. See further discussion in the Significant Developments section in the 2025 Annual Report. Our business is substantially dependent on the Australian and New Zealand economies, and could be adversely affected by a material downturn or shock to these economies or other financial systems - Strategic risk - Macroeconomic risks - Market disruption - Domestic and international economic conditions - Geopolitical risks - Credit risk Our revenues and earnings are dependent on domestic and international economic activity, business conditions and the level of financial services our customers require. Most of our business is conducted in Australia and New Zealand so our performance is influenced by the level and cyclical nature of activity in these countries. The financial services industry and capital markets have been, and may continue to be, adversely affected by volatility, global economic conditions (including inflation and rising interest rates), external events, geopolitical instability, political developments, cyberattacks or a major systemic shock. Market and economic disruptions (or the possibility of interest rates remaining higher for longer than anticipated) could cause consumer and business spending to decrease, unemployment to rise, demand for our products and services to decline and credit losses to increase, thereby reducing our earnings. These events could undermine confidence in the financial system, reduce liquidity, impair access to funding and adversely affect our customers and counterparties. Conversely, an environment with falling interest rates could reduce margins and impact earnings. Given Australia’s reliance on exports, a slowdown in economic growth or change in policy settings of Australia’s major trading partners, which may be caused by their foreign policies (including the adoption of protectionist trade measures such as tariffs or sanctions) could negatively impact the Australian economy. This could result in reduced demand for our products and services and affect supply chains, the level of economic activity and the ability of our borrowers to repay their loans. The nature and consequences of any such events are difficult to predict but each of these factors could adversely affect our business, prospects, financial performance or financial condition.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 263 Declines in asset markets could adversely affect our operations or profitability and an increase in impairments and provisioning could adversely affect our financial performance or financial condition - Market risk - Decline in asset values - Impairments - Credit risk Declines in asset markets, including equity, bond, interest rates, foreign exchange, commodities and property markets, have adversely affected, and could in the future adversely affect, our operations and profitability. Declining asset prices including as a result of changes in fiscal or monetary policies or changes in legislation, could also impact customers and counterparties and the value of security (including residential and commercial property) we hold. This may impact our ability to recover amounts owing to us if customers or counterparties default. It may also affect our impairment charges and provisions, in turn impacting our financial performance, financial condition and capital levels. Declining asset prices could also impact our wealth management business as its earnings partly depend on fees based on the value of securities and/or assets held or managed. Credit risk may arise from foreign exchange restrictions or nationalisation of borrowers, which could impair asset values or repayment capacity in offshore jurisdictions. Credit risk also arises from potential counterparty default in derivative, clearing and settlement contracts we enter into. Such risk may also arise from our dealings in, and holdings of, debt securities issued by other institutions, government agencies or sovereigns, the financial conditions of which may be affected to varying degrees by economic conditions in global financial markets. We establish provisions for credit impairment based on accounting and regulatory standards using current information and our expectations. If economic conditions deteriorate beyond our expectations, some customers and/or counterparties could experience higher financial stress, leading to an increase in impairments, defaults and write-offs, and higher provisioning beyond current modelled outcomes. Changes in regulatory expectations or requirements in relation to the treatment of customers, for example in hardship, could lead to increased impairments and/or higher provisioning. Such events could adversely affect our liquidity, capital resources, financial performance or financial condition. We could be adversely affected by the failure to maintain our credit ratings - Availability of funding - Cost of funding - Downgrade Credit ratings are independent opinions on our creditworthiness. Our credit ratings can affect the cost and availability of our funding and may be important to investors, certain institutional customers and counterparties when evaluating their investments in the Group, our products and services. A rating downgrade could be driven by a downgrade of Australia’s sovereign credit rating, a material weakening in our financial performance, or one or more of the risks identified in the 2025 Risk Factors or by other events including regulatory changes or changes to the methodologies rating agencies use to determine credit ratings. A credit rating or rating outlook could be downgraded or revised where credit rating agencies believe there is a very high level of uncertainty on the impact to key rating factors from a significant event. A downgrade to our credit ratings could adversely affect our cost of funds, collateral requirements, liquidity, competitive position, our access to capital markets and our financial stability. The extent and nature of these impacts would depend on various factors, including the extent of any rating change, differences across agencies (split ratings) and whether competitors or the sector are also impacted. We face intense competition in all aspects of our business - Margins - Regulatory scrutiny - Strategic risk - New entrants The financial services industry is highly competitive, with a range of firms, including retail and commercial banks, investment banks, other financial service companies, fintech companies and businesses in other industries with financial services aspirations (including those who are not subject to the same capital and regulatory requirements or who derive substantial revenue from other markets, which may allow them to operate more flexibly and with lower costs of funds). Emerging competitors are also increasingly altering the competitive environment by adopting new business models or seeking to use new technologies to disrupt existing business models.

GRAPHIC

264 WESTPAC GROUP 2025 ANNUAL REPORT RISK FACTORS Increased scrutiny by regulators in the sector and other legislative reforms may also change the competitive environment by stimulating competition and improving customer choice. It may also prompt increased competition from new and existing firms. Competition in the various markets we operate in has led, and may continue to lead, to a decline in our margins or market share. Deposits fund a significant portion of our balance sheet and have been a relatively stable source of funding. If we fail to successfully compete for deposits, we may face increased funding costs, leading us to seek access to other types of funding, or result in reduced lending. Our ability to compete depends on our ability to offer products and services that attract and retain customers and meet their evolving preferences and expectations. Failure to adapt could result in lost customers, which could negatively impact our business, prospects, financial performance or financial condition. For more detail refer to the Operating Environment section in the 2025 Annual Report. We have suffered, and could continue to suffer, losses due to operational risk - Operational risk - Change execution - Records management - Ineffective processes and controls - Fraud and scams - Third parties - AI - UNITE program Operational risk is the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. It includes, among other things, model, data, operations, change execution and third party risks. While we have policies, processes and controls to manage these risks, they have not always been, or may not be, effective. Ineffective processes and controls (including those of contractors, agents, authorised representatives, credit representatives, customers, trustees, brokers, independent financial advisors and other third parties, or inadequate monitoring, supervision and oversight of their activities or of our employees’ activities) have resulted in, and could continue to result in, adverse outcomes (including financial or otherwise) for Westpac, our customers, trustees, employees or other third parties. Operational breakdowns can occur if measures are implemented too quickly (including without sufficient validation), or not quickly enough, in response to external events, potentially leading to financial losses, customer remediation, regulatory scrutiny and intervention, fines, penalties and capital overlays and, depending on the nature of the failure, litigation, including class action proceedings. Examples of operational risks include: • Fraud and scams. We have incurred, and could in the future incur, losses from fraud and scams, including fraudulent applications for loans, products or services (including misrepresentations by customers (or their representatives) or brokers), incorrect or fraudulent payments or (mis)conduct (including through the use of platforms, funds, portfolios or accounts to commit investment scams or frauds, whether or not as a result of unauthorised access to our systems or our customer accounts), and misuse of accounts by money mules. Our representatives, such as our employees, may be involved including knowingly or unknowingly. Such losses, including the potential for additional customer or other third party compensation, increased levies and financial penalties (including for non-compliance), could increase significantly due to regulatory change. This includes if the Group does not adhere to obligations set out in or further to the Scams Prevention Framework within the Competition and Consumer Act 2010 (Cth), which was introduced by the Scams Prevention Framework Act 2025 (Cth). Fraudulent conduct can also arise where identification records are compromised due to third party cybersecurity events. Our risks are heightened by real-time transaction capability, and we are also exposed to contagion risk from incidents affecting other organisations. If systems, procedures and protocols for preventing and managing fraud, scams or improper access (including for improper or non-compliant purposes) to our systems and customer accounts fail, or are inadequate or ineffective, they could lead to losses which could adversely affect Westpac, our customers, business, prospects, reputation, financial performance or financial condition. Regulatory and compliance requirements can impede the ability to swiftly identify or respond to a fraud or scam, or to communicate with affected parties. • Records management. A failure to adequately implement and monitor effective records management policies and processes could impact our ability to safeguard information, locate records, respond to regulatory notices, conduct remediation, and meet record retention, protection and destruction obligations. Where there are inadequacies in implementation of the records management lifecycle in our systems or embedding records management across the Group, these risks are further heightened. Where records are not adequately protected or retained for longer than required this could increase the impacts of cyber and privacy incidents such as data breaches.

GRAPHIC

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 265 • Artificial Intelligence (AI). As AI adoption to support our customers and business increases, we may become more exposed to risks associated with the use of this technology, such as lack of transparency, over-reliance on a limited number of vendors, inaccurate data input, unintentional bias, breaches of confidentiality and privacy obligations, inaccurate or opaque outputs and unexplainable decisions, amplifications of biases or other unintended consequences that are inconsistent with our policies or values. In addition, failure or delays in adopting AI could lead to competitive disadvantages or otherwise not leveraging capability that could support management of risk or improve customer outcomes. Leveraging AI could have financial, regulatory, conduct, reputational and customer impacts. • Third party. We rely on third parties, both in Australia and overseas, to provide services to us and our customers. Failures by these third parties, including our authorised representatives and credit representatives, to deliver services as required and in accordance with law, regulation and regulatory expectations could disrupt our ability to provide products and services and adversely impact our customers, operations, financial performance or reputation. For example, we rely on third parties to provide cash transport, handling and storage services. Reduced demand for cash, disruptions or other issues (including legal or regulatory changes, litigation, claims, industrial action or the viability or solvency of providers) impacting the cash-in-transit (CIT) industry, exposes us to operational risk including loss of (or delays in accessing) significant amounts of cash held by CIT providers on our behalf (this risk is exacerbated for us as we currently provide commercial cash distribution for the industry under an arrangement with one key industry participant which terminates in July 2026), reduced availability of cash in the system generally (which could lead to a run on cash), potential increased costs (for example, to enable us/third party providers to meet legal or regulatory requirements), and related consequences where we or our customers suffer loss or damage due to disruptions to CIT services. • Change execution. We face risks in delivering technology and other change programs (such as our UNITE program), including that a change program fails to deliver the desired outcomes, or fails to reduce, pre-empt, mitigate and manage the challenges associated with transformation delivery. If our technology systems or financial infrastructure do not operate correctly, this may also cause loss or damage to us or our customers. This can also arise from complexities in our systems, and the interaction between those systems. This could include, for example, where systems issues result in incorrect fees or charges being applied to customers, or other poor customer outcomes. All these issues could potentially lead to transfer risks, cost and time overruns, business disruptions and delays, product governance failures, technology challenges, financial losses, customer remediation and retention issues, regulatory scrutiny and intervention, capital overlays and litigation. • Insurance coverage. There is a risk that we will not be able to obtain and/or have not obtained appropriate insurance coverage for the risks that we may be exposed to. This could be due to lack of available or adequate insurance, an increase in the cost of insurance, or failure of the insurance underwriter. If an insurance policy is not available or does not respond to a loss, we will not have the ability to recover such loss from an insurance policy. We could suffer losses due to market volatility - Market risk - Geopolitical risks - Volatility and disruption - Credit risk Market risk is the risk of an adverse impact on the Group’s financial performance, financial position, capital and liquidity, resulting from changes in market factors, such as foreign exchange rates, commodity prices, credit spreads and interest rates. Market risk is present in both banking book and trading book. We are exposed to market risk due to our financial markets businesses, asset and liability management, our holdings in liquid asset securities, dependence on accessing capital markets and our defined benefit plan. Changes in market factors could be driven by a variety of developments including economic disruption, geopolitical events, trade tensions, market liquidity or concerns relating to major market participants or sectors. The resulting market volatility could potentially lead to losses and may adversely affect our financial performance and capital position. As a financial intermediary, we underwrite listed and unlisted debt securities. We could suffer losses if we fail to syndicate or sell down this risk to others. This risk is more pronounced in times of heightened market volatility. Poor data quality could adversely affect our business and operations - Operational risk - Data quality - Poor customer and risk outcomes Having accurate, complete and reliable data, supported by appropriate data controls, retention and, destruction methods and access to internal frameworks and processes, is critical to the effective operation of our businesses.

GRAPHIC

266 WESTPAC GROUP 2025 ANNUAL REPORT RISK FACTORS Data plays a key role in determining how we provide products and services to customers, the effectiveness of our systems and risk management frameworks, strategic planning and our ability to make effective decisions. Some of our businesses are, and may continue to be, affected by poor data quality and/or limited data availability due to a number of factors, including inadequacies across systems, processes and policies, or ineffectively implemented data management frameworks. This could lead to poor customer service outcomes, adverse risk management outcomes, deficient system outputs and processes. This is because data quality inadequacies render such data unreliable to assist in making informed business decisions. Deficiencies with internal systems and processes could negatively impact our decision-making in areas such as the provision of credit to a customer, and the terms on which a credit facility is provided. The production of accurate data is also critical for other functions across the Group, such as financial and other reporting (internal and external). Poor data quality and availability impacts our ability to effectively monitor and manage operations across the Group, comply with production notices, respond to regulatory notices, defend and respond to litigation and conduct remediation activities. Conflicting data retention or destruction obligations may increase such risks. Poor data and/or poor data retention/destruction methods and deficient controls that result in control gaps and weaknesses could negatively impact our ability to meet compliance obligations (including regulatory reporting obligations). Previously, this has led to regulatory investigations or adverse findings and actions against the Group, and such risks remain if we fail to maintain an acceptable level of data quality and effective oversight practices. Our data related frameworks and processes must be continuously reviewed, and improved where required, to ensure our data quality and data management practices remain relevant, fit for purpose and sustainable. This is because outdated or unsustainable practices may lead to inefficient data management practices and/or poor quality data. Potential consequences from holding poor quality data and/or having poor data oversight and controls include adverse impacts to the Group’s ability to effectively operate our existing businesses, securing prospective business from third parties, and our reputation, financial performance and financial condition. Certain strategic decisions may have adverse effects on our business - Strategic risk - Warranties and indemnities - Divestments and acquisitions - Implementation risk We evaluate and implement strategic decisions, priorities and objectives including opportunities to simplify or streamline, diversify or innovate our business or products. These activities can be complex, costly and may not proceed as planned. For example, we may experience difficulties completing certain transactions, separating or integrating businesses in the scheduled timeframe or at all, disruptions to operations, diversion of management resources or higher than expected transaction costs, impacts on third parties, and there may be differing market views about a strategic choice, which may cause reputational damage. Any failure to successfully divest businesses may expose us to higher operating costs and higher inherent risks in those businesses. Decisions to retain businesses may also expose us to the higher inherent risks in those businesses. For example, our Pacific businesses face several risks including heightened operational, sovereign, financial crime and exchange control risks which could adversely affect our customers, business, prospects, reputation, financial performance or financial condition. In divesting businesses, we have given (and could in future divestments give) warranties and indemnities in favour of counterparties relating to certain pre-completion matters and certain other commitments, including in relation to transitional services. These could result in a liability to make significant payments to these counterparties while these obligations remain on foot. To manage risks related to conduct and customer redress associated with divestments, we hold additional operational risk capital pursuant to APRA’s published guidance. These contingent liabilities are described in Note 25 to the financial statements in the 2025 Annual Report. Acquiring and investing in businesses also carries risks and costs, including underperformance, assumption of unknown and unaccounted for liabilities, regulatory risks or overvaluation of a target business. Operational, cultural, governance, compliance and risk appetite differences between us and an acquired business may lead to longer and costlier integration. Internal factors, for example, inadequate funding, resourcing, business capabilities or operating model, or failing to identify, understand or respond effectively to changes in the external business environment, including economic, geopolitical, regulatory, consumer sentiment, technological, environmental, social and competitive factors, may hinder successful strategy implementation. This could adversely affect us, including our ability to increase or maintain market share or resulting pressure on margins and fees.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 267 These risks could negatively impact our business, growth prospects, reputation, engagement with regulators, financial performance or financial condition. Other risks • Failure to recruit and retain key executives, employees and Directors with appropriate skills and qualifications may have an adverse effect on our business, prospects, reputation, financial performance or financial condition. Macro-environmental factors including unemployment rates, migration levels and the level of competition in the talent market may also have an adverse impact on attracting specialist skills for the Group. In particular, attracting and retaining employees with skills and experience in technology related fields – such as cyber security and artificial intelligence – is critical in the coming years. • Changes to the critical accounting assumptions and estimates (outlined in Note 1 to the financial statements in the 2025 Annual Report) could expose the Group to losses greater than those anticipated or recognised, which could adversely affect our financial performance, financial condition and reputation.

268 WESTPAC GROUP 2025 ANNUAL REPORT INFORMATION ON WESTPAC Significant developments Westpac significant developments – Australia Changes to Board of Directors and Executive Team On 1 August 2025, Pip Greenwood commenced as an Independent Non-executive Director of the Board. On 12 May 2025, Paul Fowler commenced as the Chief Executive of Business & Wealth. On 5 August 2025, Kate Dee commenced as the new Chief People Officer, following the retirement of Christine Parker. On 12 August 2025, Westpac announced the appointment of Carolyn McCann as the new Chief Executive, Consumer, effective immediately. Carolyn McCann had been acting in that role since 12 May 2025. Carolyn Hoy commenced as the Acting Group Executive of Customer & Corporate Services on 12 May 2025. On 1 September 2025, Dr Andrew McMullan commenced in the new executive role of Chief Data, Digital and AI Officer. On 8 October 2025, Nathan Goonan commenced as the Chief Financial Officer, following the retirement of Michael Rowland. Increase in the CET1 capital operating target The Board has determined a target post dividend CET1 capital ratio of above 11.25% in normal operating conditions. This target includes consideration of APRA's increase in the minimum CET1 ratio of 0.25% to 10.50% effective 1 January 2027 and replaces the previous CET1 capital operating range of between 11.00% and 11.50%. On market buyback As at 30 September 2025, Westpac had completed $2.5 billion of the $3.5 billion on market share buyback previously announced, with 88.7 million Westpac ordinary shares purchased at an average price of $28.00. The ordinary shares bought back were subsequently cancelled. The timing and actual number of shares purchased under the buyback will depend on market conditions and other considerations. Westpac reserves the right to vary, suspend or terminate the buyback at any time. Regulatory and risk developments Financial crime Westpac continues to improve its financial crime risk management with significant ongoing work focusing on AML/CTF, Sanctions, Anti-Bribery and Corruption, the US Foreign Account Tax Compliance Act (FATCA) and Common Reporting Standard (CRS). Through this work, we continue to undertake activities to strengthen and remediate our Financial Crime Program, and to improve regulatory reporting, including in relation to International Funds Transfer Instructions, Threshold Transaction Reports, Suspicious Matter Reports, FATCA and CRS reporting and equivalent reports in jurisdictions outside Australia. With ongoing regulatory focus on financial crime, further areas of potential non-compliance have been, and may continue to be identified, and we continue to liaise with the Australian Transaction Reports and Analysis Centre (AUSTRAC), the Australian Taxation Office (ATO) and local regulators in jurisdictions outside Australia, including to remediate findings and adopt recommendations from regulators. In 2024, the Australian Parliament enacted the Anti-Money Laundering and Counter-Terrorism Financing Amendment Act 2024 (Cth), introducing major reforms to the AML/CTF regime. A substantial number of reforms will take effect from 31 March 2026, including provisions that apply to our permanent offshore establishments. In response, we are updating our policies, procedures, systems and controls. Full implementation will require a multi-year implementation program, including complex technology upgrades to customer due diligence and reporting infrastructure. Timing challenges are an industry wide issue. AUSTRAC has acknowledged this and published its regulatory expectations, noting that AUSTRAC does not expect immediate compliance. AUSTRAC does expect reporting entities to continue to implement current money laundering controls and show sustained effort and progress against implementation plans. We will continue to engage with AUSTRAC to support a phased implementation approach. Details about the consequences of failing to comply with financial crime obligations are set out in the 2025 Risk Factors. New climate reporting standards New mandatory climate-related reporting standards were approved in September 2024 by the Australian Accounting Standards Board and legislation requiring compliance has been passed by the Australian Parliament. These new requirements will apply to Westpac from its financial year ending 30 September 2026. APRA capital requirements Operational risk capital overlays In 2019, APRA applied $1 billion of additional capital overlays to our operational risk capital requirement. These overlays were applied through an increase in risk weighted assets (RWA). On 19 July 2024, APRA announced its decision to reduce Westpac’s total operational risk capital overlay from $1 billion to $500 million. On 15 October 2025, APRA announced its decision to lift the CEU and remove Westpac’s remaining $500 million operational risk capital overlay. The removal of the $500 million capital overlay will mean Westpac’s Common Equity Tier 1 (CET1) capital ratio will increase by approximately 17 basis points, reflecting a reduction in risk weighted assets of $6,250 million. This change applied with immediate effect. Further details are set out in Strengthening Risk Management (page 181).

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 269 APRA announcement to phase out AT1 capital as eligible bank capital On 8 July 2025 APRA released a consultation paper on implementing the phase out of AT1 capital instruments. This included changes to APRA's prudential and reporting frameworks resulting from the removal of AT1 capital instruments. Under the revisions, large internationally active banks such as Westpac will replace 1.5% of AT1 capital with 1.25% of Tier 2 capital and 0.25% of CET1 capital. The total CET1 requirement, including regulatory buffers, will increase from 10.25% to 10.50%. There is no overall increase in total capital requirements for banks. APRA has also proposed changes to the leverage ratio, which will see the leverage ratio calculation based on CET1 capital rather than Tier 1 capital. Should the changes be implemented as proposed, this will result in a reduction in the reported leverage ratio. The minimum leverage ratio of 3.5% is proposed to remain unchanged. APRA intends to finalise changes to the relevant prudential standards in 2025, with the updated framework coming into effect from 1 January 2027. In addition, from this date, existing AT1 capital instruments would be eligible to be included as Tier 2 capital, until their first scheduled call date. Existing Westpac AT1 capital instruments would reach their first scheduled optional redemption dates by 2031 at the latest. Westpac significant developments – New Zealand RBNZ review of overseas bank branches On 21 August 2024, the RBNZ released the proposed Branch Standard under the Deposit Takers Act 2023 (NZ). The proposed Branch Standard will require that overseas bank branches only conduct business with wholesale clients; the total size of an overseas bank’s branch cannot exceed NZ$15 billion in total assets; and dual-operating branches (such as Westpac’s New Zealand Branch) only conduct business with “large corporate and institutional clients” (LCIC). Policy decisions released by the RBNZ on 17 July 2025 propose that LCIC means those with consolidated annual turnover of over NZ$50 million, total assets of over NZ$75 million or total assets under management of over NZ$250million (for funds management entities only). The implementation date is expected to be 1 December 2028. Westpac’s New Zealand Branch currently provides financial markets, trade finance and international payment products and services to customers referred by WNZL. We expect the RBNZ’s Branch Standard will require changes to the activities Westpac’s New Zealand Branch undertakes, and as a result, WNZL may also make changes to the scope of the activities it undertakes. RBNZ review of capital settings for deposit takers On 31 March 2025, the RBNZ announced a review of the key capital settings for deposit takers. On 25 August 2025, it released a consultation paper. For Group 1 deposit takers (including WNZL) the key proposals include: • Removal of AT1 instruments from the capital stack. • Two options for capital ratio requirements: – Option 1: A total CET1 capital ratio requirement of 14%, with a total capital ratio requirement of 17% (including a prudential capital buffer (‘PCB’) ratio of 8%). – Option 2: A total CET1 capital ratio requirement of 12%, with a total capital ratio requirement of 15% (including a PCB ratio of 6%) and an additional Loss Absorbing Capacity (LAC) requirement of 6%. Tier 2 capital and LAC instruments would be required to be issued internally (for example to WBC) and LAC would take a form similar to Tier 2 capital. • More granular standardised risk weights, including lower risk weights in some areas. • Setting the long-run level for the counter-cyclical capital buffer component of the PCB at 1%. The RBNZ is expected to make its final decisions in December 2025 with the implementation timeline to be announced in the first quarter of the 2026 calendar year. The outcome of the review remains uncertain. General regulatory changes affecting our businesses RBA review of merchant card payment costs and surcharging On 15 July 2025, the RBA released a consultation paper as part of its review of merchant card payment costs and surcharging. Relevantly, the RBA proposes to remove surcharges on debit and credit cards, lower the cap on interchange fees paid by merchant acquirers to card issuers (including Westpac) and improve transparency on card payment fees. The RBA intends to complete its review in March 2026. We are considering the impact of the proposed changes, including on our products, systems and financial outcomes. Legal proceedings Our entities are parties to legal proceedings from time to time arising from the conduct of our business. Certain litigation and class actions are further described as required in Note 25 to the financial statements (page 96) in this Annual Report. Supervision and regulation Australia Within Australia, we are subject to supervision and regulation by seven principal agencies and bodies: the Australian Prudential Regulation Authority (APRA); the Reserve Bank of Australia (RBA); the Australian Securities and Investments Commission (ASIC); Australian Securities Exchange Limited (ASX); the Australian Competition and Consumer Commission (ACCC); the Australian Transaction Reports and Analysis Centre (AUSTRAC) and the Office of the Australian Information Commissioner (OAIC). APRA is the prudential regulator of the Australian financial services industry. As an Authorised Deposit-taking Institution (ADI), we report prudential information to APRA, including information in relation to capital adequacy, large exposures, credit quality and liquidity. The RBA is responsible for monetary policy, maintaining financial system stability and promoting the safety and efficiency of the payments system. The RBA is an active participant in the financial markets, manages Australia’s

270 WESTPAC GROUP 2025 ANNUAL REPORT INFORMATION ON WESTPAC foreign reserves, issues Australian currency notes and provides certain banking services to the Australian Government and its agencies. It also manages Australia's gold and foreign exchange reserves. ASIC is Australia’s corporate, markets, financial services and consumer credit regulator. It is responsible for the regulation of Australian companies and consumer protection within the financial sector. ASIC is an independent Australian government body and was established under the Australian Securities and Investments Commission Act 2001 (Cth). It carries out most of its regulatory functions and supervision under the Corporations Act 2001 (Cth) (Corporations Act). ASX acts as a market operator, clearing house and payments system facilitator for Australia’s primary national market for trading of securities issued by listed companies. Some of our securities (including our ordinary shares) are listed on the ASX and we therefore have obligations to comply with the ASX Listing Rules, which have statutory backing under the Corporations Act. The ACCC promotes competition in markets. It is the federal regulator responsible for monitoring compliance with Australia's competition and consumer protection laws, in particular the Competition and Consumer Act 2010 (Cth). AUSTRAC is Australia’s financial intelligence unit and anti-money laundering and counter-terrorism financing regulator. It oversees the compliance of Australian reporting entities (including Westpac) with the requirements under the Anti-Money Laundering and Counter-Terrorism Financing Act 2006 (Cth) and related instruments. These requirements include: • implementing programs for identifying and monitoring customers, and for managing the risks of money laundering and terrorism financing; • reporting suspicious matters, threshold transactions and international funds transfer instructions; and • submitting an annual compliance report. The OAIC's primary responsibilities are privacy, freedom of information and government information policy, including under the Privacy Act 1988 (Cth) (Privacy Act). Its functions include handling complaints about the handling of personal information, conducting investigations and undertaking enforcement actions in relation to potential breaches of the Privacy Act. New Zealand The Reserve Bank of New Zealand (RBNZ) is responsible for supervising New Zealand registered banks and protects the financial stability of New Zealand through the application of minimum prudential obligations. The New Zealand prudential supervision regime requires that registered banks publish disclosure statements, which contain information on financial performance and risk positions as well as attestations by the directors about the bank’s compliance with its conditions of registration and certain other matters. The Financial Markets Authority (FMA) and the New Zealand Commerce Commission (NZCC) are the two primary conduct and enforcement regulators. The FMA and NZCC are responsible for ensuring that markets are fair and transparent and are supported by confident and informed investors and consumers. Regulation of markets and their participants is undertaken through a combination of market supervision, corporate governance and licensing approvals. In New Zealand, other relevant regulator mandates include those relating to taxation, privacy and foreign affairs and trade. Banks in New Zealand are also subject to a number of self-regulatory regimes. Examples include Payments NZ, the New Zealand Bankers’ Association (NZBA) and the Financial Services Council (FSC). Examples of industry agreed codes include the NZBA’s Code of Banking Practice and FSC’s Code of Conduct. United States Our New York branch is a US federally licensed branch and therefore is subject to supervision, examination and regulation by the US Office of the Comptroller of the Currency and the Board of Governors of the Federal Reserve System (the US Federal Reserve) under the US International Banking Act of 1978 (IBA) and related regulations. A US federal branch must maintain, with a US Federal Reserve member bank, a capital equivalency deposit as prescribed by the US Comptroller of the Currency, which is at least equal to 5% of its total liabilities (including acceptances, but excluding accrued expenses, and amounts due and other liabilities to other branches, agencies and subsidiaries of the foreign bank). In addition, a US federal branch is subject to periodic onsite examination by the US Comptroller of the Currency. Such examination may address risk management, operations, asset quality, compliance with the record keeping and reporting, and any additional requirements prescribed by the US Comptroller of the Currency from time to time. A US federal branch of a foreign bank is, by virtue of the IBA, subject to the receivership powers exercisable by the US Comptroller of the Currency. As of 22 June 2016, we elected to be treated as a financial holding company in the US pursuant to the Bank Holding Company Act of 1956 and Federal Reserve Board Regulation Y. Our election will remain effective so long as we meet certain capital and management standards prescribed by the US Federal Reserve. Westpac and some of its affiliates are engaged in various activities that are subject to regulation by other US federal regulatory agencies, including the US Securities and Exchange Commission, US Financial Industry Regulatory Authority, the US Commodity Futures Trading Commission and the National Futures Association. Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the U.S. Securities Exchange Act of 1934, as amended, requiring each SEC reporting issuer to disclose in its annual and, if applicable, quarterly reports whether it or any of its affiliates have knowingly engaged in specified activities, transactions or dealings relating to Iran or with the Government of Iran or certain designated persons or entities involved in terrorism or the proliferation of

Section 219 requires disclosure even of certain activities not prohibited by U.S. or other law and even if such activities were conducted outside the United States by non-U.S. affiliates in compliance with local law. Westpac and WNZL have engaged in activity that is relevant for this purpose. Westpac and WNZL (as a wholly owned subsidiary) maintain compliance policies and procedures to comply with all applicable economic sanctions laws and regulations. In that context, and only after confirming that such transactions did not involve prohibited or sanctionable activity under U.S. or other economic sanctions, the above Westpac Group entities outside the United States engaged in a limited number of activities reportable under Section 219 during the period covered by this annual report, as described below. No U.S. persons or entities, or entities owned or controlled by U.S. persons were involved in these activities. There are two matters requiring disclosure for this reporting period 1 October 2024 to 30 September 2025: 1. Payments to the Embassy of Iran in Australia. During 1 October 2024 to 30 September 2025, retail and business customers of Westpac remitted AUD payments to accounts held for the Embassy of Iran in Australia with an unaffiliated bank in Australia. It was observed that the purpose of these transactions related to consular purposes of the Embassy, such as obtaining a driver’s license or passport fees and services. Westpac is not a U.S. person or owned or controlled by U.S. persons and therefore its transactions that do not include any U.S. jurisdictional elements are not subject to the Iranian Transactions and Sanctions Regulations (ITSR) at Part 560 of title 31, Code of Federal Regulations, issued by the U.S. Department of the Treasury’s Office of Foreign Assets Control. In addition, transactions that are “ordinarily incident to travel to” Iran are exempt from the ITSR (at 31 Code of Federal Regulations Section 560.210(d). All payments were facilitated through the NPP domestic payments platform. This activity contributed an insignificant amount of gross revenues and net profit to the Group. 2. Payments to the Embassy of Iran in New Zealand. During 1 October 2024 to 30 September 2025, New Zealand based customers of WNZL remitted domestic NZD payments from their accounts at WNZL to accounts held for the Embassy of Iran with an unaffiliated bank in New Zealand. It was observed that the purpose of these transactions related to diplomatic and consular duties of the Embassy. All payments were facilitated through WNZL's domestic NZD payments platform. This activity contributed an insignificant amount of gross revenues and net profit to the Group. WNZL is not a U.S. person or owned or controlled by U.S. persons and therefore its transactions that do not include any U.S. jurisdictional elements are not subject to the ITSR at Part 560 of title 31, Code of Federal Regulations, issued by the U.S. Department of the Treasury's Office of Foreign Assets Control. In addition, transactions that are "ordinarily incident to travel to" Iran are exempt from the ITSR (at 31 Code of Federal Regulations Section 560.210(d)). Westpac and WNZL intend to continue to process payments to the Embassies of Iran in Australia and New Zealand but only under limited circumstances where the Group believes the funds transfers conform to its compliance policies, procedures and all applicable sanctions laws and regulations. Anti-money laundering regulation and related requirements Australia Westpac has a Group-wide program to manage its obligations under the Anti-Money Laundering and Counter- Terrorism Financing Act 2006 (Cth). We continue to actively engage with the regulator, AUSTRAC, on our activities. Our Anti-Money Laundering and Counter-Terrorism Financing Policy (AML/CTF Policy) sets out how the Westpac Group complies with its legislative obligations. The AML/CTF Policy applies to all business segments and employees (permanent, temporary and third party providers) working in Australia, New Zealand and overseas. United States The USA PATRIOT Act of 2001 requires US financial institutions, including the US branches of foreign banks, to take certain steps to prevent, detect and report individuals and entities involved in international money laundering and the financing of terrorism. The required actions include verifying the identity of financial institutions and other customers and counterparties, terminating correspondent accounts for foreign ‘shell banks’ and obtaining information about the owners of foreign bank clients and the identity of the foreign bank’s agent for service of process in the US. The anti-money laundering compliance requirements of the USA PATRIOT Act include requirements to appoint a qualified BSA Officer, adopt and implement an effective anti-money laundering program, report suspicious transactions or activities, and implement due diligence procedures for correspondent and other customer accounts in line with the CDD rule. Westpac’s New York Branch and Westpac Capital Markets LLC maintain an anti-money laundering compliance program designed to address US legal requirements. US economic and trade sanctions, as administered by the Office of Foreign Assets Control (OFAC), prohibit or significantly restrict US financial institutions, including the US branches and operations of foreign banks, and other US persons from doing business with certain persons, entities and jurisdictions. Westpac’s New York Branch and Westpac Capital Markets LLC maintain compliance programs designed to comply with OFAC sanctions programs, and Westpac has a Group-wide program to ensure adequate compliance.

272 WESTPAC GROUP 2025 ANNUAL REPORT INFORMATION ON WESTPAC 25 to the financial statements and/or under the Significant developments section above. Where appropriate as required by the accounting standards, a provision has been raised in respect of these proceedings and disclosed in the financial statements. Cybersecurity management and governance The Group Chief Information Security Officer (CISO) reports to the Chief Information Officer, a member of the Executive Team. The CISO is a member of key cybersecurity governance forums and is responsible for leading and managing the cybersecurity function, setting the cybersecurity strategy and direction, and overseeing the implementation, operation and execution of the cybersecurity policies, standards, controls, and capabilities, including for third parties who are engaged to manage Westpac’s information assets. We have implemented a range of cybersecurity processes, technologies, and controls to facilitate our efforts to assess, identify, and manage such risks, including regular network and endpoint monitoring, access controls, vulnerability assessments, penetration testing, annual information security training for employees, and tabletop cybersecurity incident response exercises. We have an Incident Response Plan which guides the actions we are to take in the event of a suspected or confirmed cybersecurity incident. The plan includes processes to triage, investigate, contain, and remediate the incident. The plan is designed to contain and minimise the impact of a cybersecurity incident on our customers. We also maintain a Business Continuity Plan, which provides procedures for maintaining the continuity of critical business processes in the event of business interruption, including any that involve cybersecurity incidents which may significantly impact our operations. Our cybersecurity team is informed about and monitors the prevention, mitigation, detection and remediation of cybersecurity threats through their management of, and participation in, the strategy processes. The CISO and the cybersecurity team have relevant expertise and experience in various aspects of cybersecurity, such as strategy, governance, risk management, threat intelligence, incident response, security operations, architecture, engineering, testing and awareness. The CISO has extensive experience in information technology and cybersecurity. The cybersecurity team consists of qualified and competent professionals who have diverse backgrounds and skills in cybersecurity. The cybersecurity team regularly participates in training, education, and development programs to enhance their knowledge and skills to keep up with the evolving cybersecurity landscape. As part of its cybersecurity risk management, Westpac engages with third parties for independent reviews and assessments of its cybersecurity policies, standards, controls, and capabilities. These third parties include external auditors, industry bodies, consultants, and specialists. The purpose of these engagements is to obtain assurance, validation, benchmarking and improvement recommendations on Westpac's cybersecurity posture and maturity. Westpac holds ISO27001, PCI-DSS and SOC 2 Type 2 certifications for areas of the Group. The CISO escalates key cybersecurity risk and control issues, as appropriate, to the Technology Risk Committee (TRC) or to the appropriate Line of Business and Divisional Committees. The TRC, a senior management committee, oversees the technology function and technology risk management. The TRC reports to the Group Executive Risk Committee (GRISKCO), the executive management committee responsible for overseeing the group's strategy, performance, and risk management. The Board of Directors receives periodic updates from the CIO and the CISO regarding cybersecurity matters. The Board is ultimately responsible for the oversight of the cybersecurity risk management. The Board delegates some of its oversight responsibilities to the Board Risk Committee, which assists the Board in the oversight of cybersecurity risk management. During the period covered by this 2025 Annual Report, we have not experienced any cybersecurity incidents which have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition. However, institutions like ours, as well as our employees, service providers and other third parties have experienced a significant increase in information security and cybersecurity risk in recent years and will likely continue to be the target of increasing sophisticated cyber-related attacks.

274 WESTPAC GROUP 2025 ANNUAL REPORT GROUP PERFORMANCE Full Year 2025 results overview Group performance Full Year 2025 results overview Our financial performance reflected our strategy of balancing growth and return while investing for the future. We maintained a strong financial position with capital, funding and liquidity all above regulatory minimums. Fully franked ordinary dividends increased to 153 cents per share, including a final dividend of 77 cents per share. That equates to a full year ordinary dividend payout ratio of 76% of net profit, towards the upper end of our preferred payout range. Net profit was delivered through disciplined management of net interest margins and balance sheet growth across our businesses. The rise in operating income reflected our strategy of balancing growth and returns. Growth in operating expenses reflected higher staff and technology costs, while the low level of impairment charges reflected credit quality improvements across all segments. The balance sheet recorded solid growth with deposits and loans rising by 7% and 6% respectively. Consumer deposits increased 10%, deposits in Business rose 6% and Institutional deposits climbed 10%. Business lending was up 15% with strong growth in our target sectors. In Institutional, deeper client relationships and improved service supported loan growth of 17%. Housing loans, excluding RAMS, rose 5%. We are focused on building stronger customer relationships while investing to improve our market position to deliver long term value for shareholders. Customer service excellence is essential to our future success. We’ve improved our everyday banking experience through simplifying onboarding and improving the rewards for loyalty. We’re expanding with more bankers offering local expertise and new retail and business banking service centres in growth regions. We are transforming the company through our ‘One Best Way’ approach, driving simplification, consistency, efficiency and innovation to make banking easier and more cost-effective. UNITE aims to unlock value by resolving structural legacy technology and operational issues. The Discovery phase is complete and 8 initiatives have been delivered. Notable Items Notable Items Notable Items reduced net profit after tax in 2025 by $56 million (2024: $123 million reduction) and increased net profit after tax in Second Half 2025 by $84 million (First Half 2025: $140 million reduction). Details of Notable Items (post tax) are presented below: Category Net profit impact Full Year 2025 Net profit impact Second Half 2025 Detail Hedging items $56 million reduction $84 million benefit • The unrealised fair value loss on hedges of accrual accounted term funding transactions for the year was $43 million reduction (2H25: $49 million benefit; 1H25: $92 million reduction; 2024: $128 million reduction); and • The net ineffectiveness on qualifying hedges was a reduction of $13 million (2H25: $35 million benefit; 1H25: $48 million reduction; 2024: $5 million benefit). Total Notable Items $56 million reduction $84 million benefit Review of earnings Review of earnings Net interest income Net interest income increased 3% to $19,380 million. Notable Items relating to hedging items including unrealised revaluation of economic hedges of term funding reduced income by of $93 million. Excluding Notable Items net-interest income increased by 3% to $19,473 million with key drivers outline below. Net interest income excluding the impact of Notable Items Net interest income increased 3% to $19,473 million. Key drivers included: • Higher core net interest income, up 3% to $18,191 million. Balance sheet growth was partly offset by lower net interest margin; • Treasury and Markets income, down 2% to $1,282 million due to a stronger performance from Treasury in the prior year. Average interest-earning assets increased by 3% to $1,002.9 billion, including growth of 11% in business loans and 2% in housing loans. This was partially offset by the reduction in personal loans and the runoff and subsequent sale of the auto finance portfolio in March 2025. Average liquid assets increased by 2% while other interest-earning assets decreased by 8% due to the reduction in collateral balances.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 275 Review of earnings (Continued) Net interest margin movement The NIM of 1.93% was flat. NIM comprised: • Core NIM of 1.81%, which contracted by 1 basis point with key drivers described below; • Treasury and Markets contribution of 13 basis points, which was stable; and • Notable Items relating to hedging items including unrealised revaluations of economic hedges of term funding detracted 1 basis point. Net interest margin excluding the impact of Notable Items NIM decreased 1 basis point to 1.94%. NIM comprised: • Core NIM of 1.81%, which contracted by 1 basis point with key drivers described below; and • Treasury and Markets contribution of 13 basis points, which was stable. Core NIM comprised the following movements: • Loan interest spread: 1 basis point narrower. Higher spreads in New Zealand mortgages driven by fixed rate repricing was more than offset by tighter spreads in Australia due to competition and the sale of the auto finance portfolio; • Deposit interest spread: 2 basis points decrease with a mix shift towards lower spread savings products, margin compression in term deposits and the impact from lower interest rates. Earnings on hedged deposits were higher; • Liquid Assets: 2 basis points increase as average liquid assets rose by less than average lending assets; • Wholesale funding: 1 basis point decrease from the impact of higher funding costs, with the final Term Funding Facility (TFF) draw downs maturing in the prior year; and • Capital and Other: 1 basis point increase primarily from higher earnings on hedged capital balances. Loans Loans increased by 6% to $851.9 billion and comprised the following movements: • Growth in Australian housing loans, excluding RAMS, of 5% to $497.0 billion, mainly in variable rate mortgages with the mix of investor lending increasing throughout the year as part of a targeted strategy; • RAMS housing loans contracted by 28% to $21.6 billion as the portfolio is closed to new business; • Australian personal lending was down 4%1 to $9.0 billion reflecting subdued new lending; • Growth in Australian business lending of 14%1 to $221.8 billion. Growth in Institutional lending was in the infrastructure, resources, energy and property sectors. Business segment growth was diversified, with strong growth in the target sectors of health, professional services and agriculture and the SME sub segment; • Growth in New Zealand lending of 4% to NZ$107.3 billion with growth mainly in owner occupied mortgages; and • Growth in other overseas loan balances to $12.6 billion. Execution of our strategy in Institutional has led to offshore financing where there is a strong nexus to Australia. Deposits Customer deposits grew by 7% to $723.0 billion and comprised the following movements: • Australian deposits up 8% to $642.6 billion, supported by strong growth in household deposits, an increase in business transaction balances driven by new account openings and retention, and a targeted institutional strategy to maintain strength in the public sector and grow share in financial institutions; • New Zealand deposits were up 2% to $81.0 billion in NZ$ terms reflecting an increase in savings and non-interest bearing balances as customers preferred the flexibility in the falling interest rate environment; and • Other overseas deposits were up 39% to $9.2 billion, primarily from growth in Institutional offshore term deposits. The deposit to loan ratio of 84.9% was 137 basis points higher than 30 September 2024, with deposit growth more than funding loan growth during the year. Non-interest income Non-interest income increased by 6% to $3,004 million. This included Notable Items of $13 million related to hedging items including unrealised revaluations of economic hedges. Excluding Notable Items non-interest income increased by 5% to $2,991 million with key drivers outline below. Non-interest income excluding the impact of Notable Items Non-interest income increased by 5% to $2,991 million. 1. Movement excludes the auto finance portfolio which was sold in March 2025.

276 WESTPAC GROUP 2025 ANNUAL REPORT GROUP PERFORMANCE Review of earnings (Continued) Net fee income increased by 4% to $1,732 million reflecting an increase in card fees and higher business and Institutional lending fees from a larger balance sheet. Net wealth management income increased by 8% to $476 million from higher funds under administration. Trading and other income increased by 7% to $783 million reflecting higher sales and risk management income, including rates and foreign exchange. Operating expenses Total operating expenses increased 9% to $11,916 million. The increase included a restructuring charge of $273 million in the Second Half of 2025 to support targeted productivity initiatives under our Fit for Growth program. Excluding this charge, operating expenses increased by 6% due to the ramp up in UNITE investment, wage growth and higher software amortisation. Lower occupancy costs provided a partial offset. The expense to income ratio excluding Notable Items was 53.0%, up from 50.3%. Staff expenses1 increased by 7% to $6,326 million mainly due to wage growth, UNITE and the investment in bankers. Average FTE increased by 1% with the increase to support UNITE and the investment in bankers more than offsetting reductions from productivity initiatives. Occupancy expenses decreased by 7% to $652 million with further reductions in the Group's corporate and branch footprint. Technology expenses increased 13% to $3,136 million due to higher costs related to the UNITE program, an increase in software amortisation related to projects completed in prior years and higher software maintenance and licensing costs. Other Expenses1 decreased by 3% to $1,529 million due to lower professional and servicing costs and higher costs in the prior year from the closure of RAMS, partly offset by higher litigation and remediation costs, and advertising spend. Fit for Growth restructuring expenses to support targeted productivity initiatives were $273 million in the Second Half of 2025. Investment spend Total investment spend of $1,918 million was 9% higher, primarily due to the increased investment in UNITE. The proportion of investment spend expensed increased by 4 percentage points to 60%. UNITE accounted for 34%, growth and productivity initiatives accounted for 30% and 36% was directed towards risk and regulatory activities. UNITE investment spend increased to $660 million with 74% expensed. Key achievements: • One identity verification process following the consolidation of 20 processes; • Functionality for multiple offset accounts for all eligible home loan customers, providing customers with greater choice and control over their finances; • One BankTrade system, simplifies process while reducing risk and complexity; • Transitioned customers to a single Private Bank under the Westpac brand enabling customers to benefit from an enhanced service offering; and • Banker and customer experience has improved with the consolidation of the two chat platforms to one. Spend in the year focused on prioritised initiatives, including: • Mortgage simplification to a single suite of products, processes and applications; • Moving to One Wealth Platform; • Migrated 6,000 bankers onto Digital Banker; • Consolidating seven collections systems to one system; and • Streamlining fraud operations from four workflow systems to one solution.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 277 Review of earnings (Continued) • Implemented AI-driven solutions and integrated M365 Copilot for over 10,000+ employees to help streamline workflows, reduce manual effort and enhance the quality of work; and • Technology and digital capability improvements for customer experience in New Zealand. Risk and Regulatory investments include: • Ongoing improvement of scam prevention capabilities to enhance customer protection; • Core payments platform upgraded, including migration of domestic high value payments and international payments processing to a new application; • Compliance with revised regulation, including the 2025 Banking Code of Practice, Prudential Standard CPS 230, Operational Risk Management and Prudential Standard APS 117, Capital Adequacy - Interest Rate Risk in the Banking Book; and • Continuing to enhance records management systems and processes. Capitalised software Capitalised software decreased $261 million or 10% compared to September 2024. The decrease reflects increased amortisation due to the completion of key projects such as One Banking Platform, payments and investment to comply with RBNZ’s outsourcing policy, BS11. Additions included ongoing investment in payment systems and UNITE. This has resulted in average amortisation period reducing by 0.4 years to 2.7 years from September 2024. Credit impairment charges The credit impairment charge of $424 million represented 5 basis points of average loans, down from 7 basis points in the prior year. The lower impairment charge was mainly due to an increase in write-backs and recoveries partly offset by a higher CAP charge. The CAP charge of $458 million comprised write-offs of $561 million which was partly offset by a benefit in other changes in CAP of $103 million. Write-offs were largely within the credit card and personal loan portfolios. The other changes in CAP were due to: • A reduction from an improved economic outlook for commercial property prices and interest rates; • A reduction in mortgage 90+ day delinquencies from 1.05% to 0.70%; • An increase in the downside scenario weight of 5 percentage points reflecting a rise in geopolitical instability; and • An increase for new portfolio overlays. The IAP benefit of $34 million comprised: • New IAPs of $408 million, mostly in the services and wholesale & retail trade sectors and the mortgages portfolio; • Recoveries of $247 million, mostly within the credit cards and personal loan portfolios; and • Write-backs of $195 million, mostly in the wholesale & retail trade and manufacturing sectors. Income tax expense The rise in the effective tax rate to 31.0%, up from 30.8%, was mainly due to benefits from prior period tax adjustments in Full Year 2024 not repeated in Full Year 2025. The effective tax rate is above the Australian corporate tax rate of 30%. Credit quality Credit quality Stressed exposures as a percentage of total committed exposures were 1.28% a decrease of 17 basis points. The composition and drivers of stressed exposures were: • Impaired exposures of 15 basis points: a 1 basis point decrease reflecting lower impaired balances in the Business portfolio; • Non-performing, 90+ days past due and not impaired exposures of 32 basis points: a 15 basis point decrease reflecting lower mortgage 90+ day delinquencies; • Non-performing, less than 90 days past due and not impaired exposures of 30 basis points: a 7 basis point increase reflecting a rise in mortgages categorised as non-performing after exiting 90+ days past due; and • Watchlist and substandard exposures of 51 basis points: an 8 basis point decrease reflecting lower stress in the Business and New Zealand portfolios. Impaired exposures to gross loans were flat at 0.24%. The provision coverage of the impaired portfolio was 40%, down from 41% at 30 September 2024. Impaired exposures have an appropriate level of provision cover.

GRAPHIC

278 WESTPAC GROUP 2025 ANNUAL REPORT GROUP PERFORMANCE Credit quality (Continued) Portfolios Stressed exposures in Institutional reduced by 6 basis points to 0.70%, driven by strong volume growth along with lower stress in the trade and, transport and storage sectors. Impaired exposures to TCE increased by 4 basis points to 0.09%, driven by a large single name downgrade in the services sector. Australian Business stressed exposures decreased by 43 basis points to 4.81%, due to improvement in the property and trade sectors. Impaired exposures to TCE decreased by 16 basis points to 0.49% with improvement in the agriculture and manufacturing sectors. Australian mortgage 90+ day delinquencies decreased 39 basis points to 0.73% due to a reduction in hardship and a change to serviceability treatment. Properties in possession were 154, a reduction of 47 reflecting fewer properties being repossessed. Australian other consumer 90+ day delinquencies reduced 34 basis points to 1.13%, driven by the sale of the auto finance portfolio in First Half 2025. In New Zealand, stressed exposure to TCE decreased by 26 basis points to 1.47%. This was driven by a reduction in watchlist exposures in the mining and agriculture sectors. New Zealand mortgage 90+ day delinquencies were 3 basis points lower at 0.46%. Other consumer 90+ day delinquencies were 17 basis points lower at 0.70%. Improvements reflect easing of cost of living pressures. Provisioning Total provisions decreased 2% to $4,987 million driven by a reduction in CAPs. The decrease in modelled CAPs of $168 million was due to: • An improved outlook for commercial property prices and interest rates; • Lower mortgage 90+ day delinquencies; and • The sale of the auto finance portfolio. This was partly offset by a 5 percentage point increase in the downside scenario weight reflecting a rise in geopolitical instability, including in relation to the potential impact of international trade policies. Overlays were $59 million higher. Key movements included: • New overlays related to portfolio seasoning and geographical areas experiencing higher stress not included in modelled outcomes; • Release of the construction sector, Australian mortgages and consumer finance overlays as the expected risks did not materialise or are reflected in modelled outcomes. IAPs remained relatively flat over the year.

Consumer Consumer Net profit increased 4% to $2,282 million. The 4% increase in pre-provision profit included a modest impact from segment compositional changes in Full Year 2025. Full Year 2024 comparatives have not been restated. Excluding composition changes, pre-provision profit also increased 4%, with operating income rising 4% and operating expenses increasing 4%. The increase in operating income reflected 3 basis points of net interest margin expansion while expenses rose reflecting a step up in UNITE spend and inflationary pressures that were partly offset from the benefits of a simpler operating model and a smaller property footprint. Net interest income up 3% • The net interest margin increased 3 basis points to 1.73%. Key drivers included: – Favourable portfolio mix as deposit growth outpaced lending growth, resulting in a higher deposit to loan ratio; – Stabilising lending spreads reflecting customers switching from lower spread fixed rate mortgages to higher spread variable rate mortgages was offset by competition to both retain and attract new mortgage customers; – Lower deposit spreads reflecting a mix shift towards higher interest rate, lower margin savings accounts, a lower interest rate environment and compression in term deposit spreads. These impacts were partly offset by higher returns on hedged deposits and proactive repricing; – Higher funding costs primarily due to the widening of the spread between the bank bill and overnight index swap rates; and – Higher returns on hedge capital balances provided a benefit. • Loans increased by 3% to $525.4 billion. Mortgage growth of 3% was below system, reflecting the decision to close RAMS to new business. Excluding this impact, mortgages grew 5%, representing 0.8x APRA housing system growth. Almost all new flow was in variable rate mortgages, with the mix of investor loans increasing throughout the year as part of a targeted strategy; • Deposits were up 10% to $366.3 billion representing 1.0x APRA household deposits system growth. Growth in savings balances of $20.9 billion reflected the continued shift in customer preference to towards higher yielding flexible products. Mortgage offset balances increased by 15% to $72.7 billion as fixed rate mortgage customers shifted onto variable rate mortgages with deposit offset features; and • With deposit growth continuing to exceed loan growth, the deposit to loan ratio improved 417 basis points to 69.7%. Non-interest income up 6% • Non-interest income increased 6% to $561 million due to higher credit card fees and scheme incentives, which was partly offset by higher customer remediation costs. Expenses up 3% • Operating expenses increased 3%. Excluding compositional changes operating expenses increased 4%. This was driven by: – The step up in UNITE investment, although this was partly offset by lower spend across other investments; and – Inflationary pressures from both wages and salaries and third-party vendor costs. • The benefits from a simpler operating model and a smaller property footprint, including branches and ATMs, partly offset other cost pressures. Impairment charge of $217 million • Impairment charges to average loans were 4 basis points, down 1 basis point from the prior year. The charge reflects write-offs in cards and personal lending and an increase in the downside scenario weight. This was partly offset by a release of portfolio overlay provisions. • Stressed exposure to TCE improved by 19 basis points to 0.91% reflecting the continued resilience of customers. Mortgage 90+ day delinquencies decreased 39 basis points to 0.73% due to a reduction in hardship and a change to serviceability treatment. Other consumer loan 90+ day delinquencies decreased 10 basis points to 1.13%.

280 WESTPAC GROUP 2025 ANNUAL REPORT SEGMENT REPORTING Business & Wealth Business & Wealth Net profit declined 7% to $2,186 million. Pre-provision profit fell 4% to $3,383 million reflecting the impact of segment compositional changes in Full Year 2025. Full Year 2024 comparatives have not been restated. This includes moving the merchant services business from Business & Wealth to Institutional and auto finance from Business & Wealth to Group Businesses following the completion of its sale. Excluding the impact of compositional changes, pre-provision profit fell 1% with a 3% increase in operating income more than offset by a 10% increase in operating expenses. Operating income reflected strong growth in lending balances which was partly offset by a lower net interest margin, while operating expenses increased due to the step up in UNITE spend and investment in front line bankers. Net interest income flat • Excluding compositional changes, net interest income increased 3%. • Strong balance sheet growth was offset by 50 basis points of margin contraction. The decline in net interest margin included the impact from segment compositional changes and provision releases in the prior period. Excluding these impacts, the net interest margin contracted by 39 basis points. Drivers included: – Portfolio mix shift as lending growth outpaced deposit growth, reflected in a lower deposit to loan ratio; – Lower deposit spreads from the impact of a lower cash rate environment and an increase in customers switching to higher yielding accounts. Favourable product mix with growth in transaction and savings accounts and a contraction in term deposits as well as higher returns on hedged deposits partly offset these impacts; and – Lower lending spreads reflecting competitive market dynamics, partly offset by higher returns on hedged capital balances. • Loans increased by 13% to $115.2 billion. Business lending grew 15% with growth diversified across most sectors and segments. Target sectors of agriculture, health and professional services all grew between 17% and 24%. This was partly offset by the wind down and subsequent sale of the $2.1 billion auto finance portfolio; and • Deposits increased 6% to $152.3 billion primarily driven by strong new account growth and proactive retention strategies. Non-interest income down 4% • Non-interest income decreased 4% reflecting compositional changes. Excluding this impact, non-interest income increased 7% reflecting: – Higher platforms revenue, reflecting a 9% increase in funds under administration from strong equity markets and flows into the GIS platform; and – Higher lending fees due to a larger loan book. Expenses up 4% • Operating expenses increased 4%. Excluding compositional changes, operating expenses increased 10% reflecting: – The step up in UNITE investment; – An investment in 135 business bankers and banker tools to drive growth; and – Inflationary pressures on salaries and wages and third party vendor costs, largely offset by lower investment spend on non-UNITE initiatives. Impairment charge of $245 million • The impairment charge of 23 basis points of average loans compared to 14 basis points in the prior year. The charge reflects higher overlays, an increase in the downside scenario and new IAPs in the wholesale & retail trade sector. • Credit quality metrics improved with stressed exposures to TCE decreasing 55 basis points to 5.01%, mostly within the property sector. The proportion of impaired exposures to TCE decreased 18 basis points to 0.50%.

Pre-provision profit increased 6% to $2,161 million with the inclusion of the merchants business following compositional changes to segments in Full Year 2025. Full Year 2024 comparatives have not been restated. Excluding this impact, pre-provision profit increased 2%, with a 5% rise in operating income more than offsetting an 11% increase in operating expenses. The growth in operating income reflects lending growth and higher earnings on capital. The 11% increase in operating expenses was driven by increased investment spend, including the step up of UNITE and higher software amortisation, in addition to an increase in bankers to support growth. Net interest income up 8% • Solid balance sheet growth more than offset a decline in the net interest margin. The net interest margin contracted 5 basis points, including a benefit from Markets and composition changes. Excluding this, the net interest margin declined 13 basis points reflecting an increase in funding costs, in part due to lending growth outpacing deposit growth, and lending spreads contracted reflecting market dynamics. These were partly offset by higher returns on hedged capital; • Loans increased 17% to $117.7 billion from strengthening relationships with existing clients, predominantly in the infrastructure, property and energy sectors. Offshore lending where there is a clear nexus to Australia or New Zealand also contributed to growth; and • Deposits increased 10% to $131.4 billion driven by transactional, term products and savings accounts. The growth reflects a targeted strategy to maintain strength in the public sector and grow in financial institutions. Non-interest income up 10% • Non-interest income increased 10% to $1,395 million. Excluding the impact of composition changes, non-interest income increased 2%. This was driven by: – Higher fee income from a larger loan book; and – A modest increase in Markets reflecting higher sales and risk management income including rates and foreign exchange. Expenses up 12% • Expenses were up 12% to $1,647 million. Excluding the impact of composition changes, expenses increased 11%. Movements reflected: – Higher investment costs including software amortisation from prior investments and the ramp up of UNITE; and – Inflationary pressures on salaries and wages as well as an increase in front-line staff to support relationships and lending growth. Impairment benefit of $1 million • Impairment benefit of $1 million, compared to a $120 million charge in the prior year. The benefit was driven by revisions to economic forecasts partly offset by new IAPs within the service sector. • Stressed exposures to TCE improved 6 basis points to 0.70% driven by portfolio growth and lower stress in the wholesale & retail trade and transport & storage sectors. The proportion of impaired exposures to TCE deteriorated modestly to 0.09%.

282 WESTPAC GROUP 2025 ANNUAL REPORT SEGMENT REPORTING New Zealand New Zealand All figures are in NZ$ unless otherwise stated. Net profit increased 13% to $1,197 million, including a credit impairment benefit. Pre-provision profit increased 8% to $1,618 million, reflecting an 8% increase in operating income which more than offset a 7% increase in operating expenses. Operating income reflected growth in lending and a higher net interest margin, while operating expenses were driven by higher staff expenses, third party vendor costs, software amortisation and higher investment spend. Net interest income up 9% • The net interest margin increased 15 basis points, reflecting improved housing lending spreads and higher returns on transaction deposits and capital balances. This was partly offset by competition for term deposits and lower business lending spreads from competitive pressures. • Loans increased 4%, primarily driven from housing growth. Business conditions continue to reflect a challenging economic environment. Key drivers included: – Mortgage growth of 5%, represents 0.9x RBNZ housing system growth. Expectations for the RBNZ to continue to cut interest rates drove a shift in customers preference to shorter fixed rate tenors and variable rate loans; and – Business lending growth of 2% reflecting higher corporate and medium sized business lending. This was partly offset by a decline in agriculture and institutional lending. • Deposits increased 2% to $81.0 billion, reflecting an increase in savings and transaction balances as customers preferred to retain funds in at call accounts in a falling interest rate environment. The contraction in term deposits reflected a reduction in Institutional term deposits as growth in higher quality household deposits was achieved. Non-interest income down 3% • Non-interest income declined 3% to $270 million reflecting lower cards income. Expenses up 7% • Operating expenses increased 7%, reflecting: – Higher staff expenses and third-party vendor costs; – Increase in technology investment to enhance core infrastructure and digital capability; and – Higher software amortisation. Impairment benefit of $44 million • The impairment benefit to average loans was 4 basis points, compared to a charge of 3 basis points in the prior year. The benefit was driven by write-backs and a CAP benefit, largely in the mortgages portfolio. • Stressed exposures to TCE decreased 26 basis points to 1.47% mostly due to lower watchlist exposures in the agriculture sector. Impaired exposures to TCE increased by 3 basis points to 0.19%.

Excluding Notable Items, net profit decreased of 3% and pre-provision profit declined by 4% with operating income stable while operating expenses increased 7%. Operating income reflected solid loan growth constrained by a modest decline in net interest margin. The increase in operating expenses was driven by higher software amortisation and technology costs along with the impact of closing RAMS to new business. Net interest income increased 2% as an increase in average interest earnings assets more than offset a 2 basis point decline in net interest margin, from 1.95% to 1.93%. Excluding Notable Items net interest income increased 3% with stronger Treasury and Markets performance and lending growth offsetting a modest decline in net interest margin. Average interest earning assets increased 3% with growth in business lending and owner-occupied mortgages, partly offset by auto finance loan runoff. The deposit to loan ratio increased to 83.5%, with customer deposit growth of 5% broadly funding loan growth during the year. Non-interest income decreased by 15%. The contribution to revenue from business sold was $140 million in the prior period. This related to Advance Asset Management Limited, BT's superannuation business and Westpac Life Insurance Ltd prior to their exit. Excluding Notable Items and the impact of businesses sold in the prior period, non-interest income decreased 5% driven by reduction on other income attributable to losses on commodity and FX derivatives. Operating expenses were 2% higher. Excluding Notable Items operating expenses increased by 7% mainly due to higher software amortisation, higher third-party technology vendor expenses and costs related to closing RAMS to new business. The reduction in operating expenses was partly offset by Cost Reset actions. Credit impairment charges of $537 million represented 7 basis points of average loans, down from 9 basis points in the prior year. The charge reflected the impact of: • Higher inflation, rising interest rates and expectation of slowing economic activity; and • Deterioration in credit quality metrics through the year including increased stressed exposures in mortgages and institutional lending. The effective tax rate of 30.8% was slightly above the Australian corporate tax rate of 30% due to certain non tax deductible expenses. The Board determined a final ordinary dividend of 76 cents per share. The FY24 ordinary dividends of $1.51 per share were 9 cents or 6% higher than the ordinary dividends in the prior year and represented a payout ratio of 74.6%. The 2024 final ordinary dividend was fully franked.

288 WESTPAC GROUP 2025 ANNUAL REPORT EXHIBIT 15.4 Cybersecurity management and governance Exhibit 15.4 Cybersecurity management and governance The Group Chief Information Security Officer (CISO) reports to the Chief Information Officer, a member of the Executive Team. The CISO is a member of key cybersecurity governance forums and is responsible for leading and managing the cybersecurity function, setting the cybersecurity strategy and direction, and overseeing the implementation, operation and execution of the cybersecurity policies, standards, controls, and capabilities, including for third parties who are engaged to manage Westpac’s information assets. We have implemented a range of cybersecurity processes, technologies, and controls to facilitate our efforts to assess, identify, and manage such risks, including regular network and endpoint monitoring, access controls, vulnerability assessments, penetration testing, annual information security training for employees, and tabletop cybersecurity incident response exercises. We have an Incident Response Plan which guides the actions we are to take in the event of a suspected or confirmed cybersecurity incident. The plan includes processes to triage, investigate, contain, and remediate the incident. The plan is designed to contain and minimise the impact of a cybersecurity incident on our customers. We also maintain a Business Continuity Plan, which provides procedures for maintaining the continuity of critical business processes in the event of business interruption, including any that involve cybersecurity incidents which may significantly impact our operations. Our cybersecurity team is informed about and monitors the prevention, mitigation, detection and remediation of cybersecurity threats through their management of, and participation in, the strategy processes. The CISO and the cybersecurity team have relevant expertise and experience in various aspects of cybersecurity, such as strategy, governance, risk management, threat intelligence, incident response, security operations, architecture, engineering, testing and awareness. The CISO has extensive experience in information technology and cybersecurity. The cybersecurity team consists of qualified and competent professionals who have diverse backgrounds and skills in cybersecurity. The cybersecurity team regularly participates in training, education, and development programs to enhance their knowledge and skills to keep up with the evolving cybersecurity landscape. As part of its cybersecurity risk management, Westpac engages with third parties for independent reviews and assessments of its cybersecurity policies, standards, controls, and capabilities. These third parties include external auditors, industry bodies, consultants, and specialists. The purpose of these engagements is to obtain assurance, validation, benchmarking and improvement recommendations on Westpac's cybersecurity posture and maturity. Westpac holds ISO27001, PCI-DSS and SOC 2 Type 2 certifications for areas of the Group. The CISO escalates key cybersecurity risk and control issues, as appropriate, to the Technology Risk Committee (TRC) or to the appropriate Line of Business and Divisional Committees. The TRC, a senior management committee, oversees the technology function and technology risk management. The TRC reports to the Group Executive Risk Committee (GRISKCO), the executive management committee responsible for overseeing the group's strategy, performance, and risk management. The Board of Directors receives periodic updates from the CIO and the CISO regarding cybersecurity matters. The Board is ultimately responsible for the oversight of the cybersecurity risk management. The Board delegates some of its oversight responsibilities to the Board Risk Committee, which assists the Board in the oversight of cybersecurity risk management. During the period covered by this 2025 Annual Report, we have not experienced any cybersecurity incidents which have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition. However, institutions like ours, as well as our employees, service providers and other third parties have experienced a significant increase in information security and cybersecurity risk in recent years and will likely continue to be the target of increasing sophisticated cyber-related attacks.

292 WESTPAC GROUP 2025 ANNUAL REPORT READING THIS REPORT Non-AAS financial measures Non-AAS financial measures Westpac’s statutory results are prepared in accordance with AAS and are also compliant with IFRS. In assessing Westpac’s performance and that of our operating segments we use a number of financial measures, including amounts, measures and ratios that are presented on a non-AAS basis, as described below. Non-AAS financial measures and ratios do not have standardised meanings under AAS. As such they are unlikely to be directly comparable to similar measures presented by other companies and should not be viewed in isolation from, or as a substitute for, the AAS results. Our non-AAS measures fall within the following categories: MEASURE/RATIO DESCRIPTION FURTHER INFORMATION Income statement measures excluding Notable Items The net interest income, non-interest income, operating expenses and segment reporting sections of this report include performance measures that exclude Notable Items. Notable Items are items that management believes are not reflective of Westpac’s ongoing business performance. Details of Notable Items are included in Impact of Notable Items (page 294). Performance measures which are adjusted for one or more of these items include: • Net interest income • Non-interest income (including net fee income, net wealth management, trading income and other income) • Net operating income (including net interest income and non-interest income) • Operating expenses (including staff expenses, occupancy expenses, technology expenses and other expenses) • Pre-provision profit • Income tax (expense)/benefit • Net profit • Net profit attributable to owners of WBC • Net profit attributable to owners of WBC (adjusted for RSP dividends) • Core net interest income • Core NIM Management considers this information useful as these measures provide a view that reflects Westpac’s ongoing business performance. See pages 297-298 Pre-provision profit Pre-provision profit is net profit/(loss) excluding credit impairment (charges)/benefits and income tax (expense)/benefit. This is calculated as net interest income plus non-interest income less operating expenses. This includes (charges)/benefits relating to provisions and impairment other than from expected credit losses. Management considers this information useful as this measure provides readers with a view of the impact of the operating performance of Westpac. See page 298 Basic earnings per share excluding Notable Items and Diluted earnings per share excluding Notable Items Basic earnings per share excluding Notable Items is calculated as net profit attributable to owners of WBC (adjusted for RSP dividends) excluding Notable Items divided by the weighted average number of ordinary shares on issue during the period, adjusted for treasury shares. Diluted earnings per share is calculated by adjusting the basic earnings per share excluding Notable Items by assuming all dilutive potential ordinary shares are converted. Management considers this information useful as these measures provide a view of the basic and diluted earnings per share based on the ongoing operating performance of Westpac. See pages 297-298

294 WESTPAC GROUP 2025 ANNUAL REPORT READING THIS REPORT Non-AAS financial measures (Continued) Impact of Notable Items To assist in explaining our financial performance, we report Notable Items, which represent certain items that are not considered to be reflective of Westpac's ongoing business performance. Notable Items fall into the following categories: • Unrealised fair value gains/(losses) on economic hedges that do not qualify for hedge accounting • Net ineffectiveness on qualifying hedges • Large items that are not reflective of Westpac's ordinary operations. In individual reporting periods large items may include: – Provisions for remediation, litigation, fines and penalties – The impact of asset sales and revaluations – The write-down of assets (including goodwill and capitalised software) – Restructuring costs In determining dividends, the impact of Notable Items is typically excluded. Notable Items reduced net profit after tax in 2025 by $56 million (2024: $123 million, 2023: $173 million). Details of Notable Items (post tax) impacting on 2025 results are presented below: Category Net profit impact Detail 2025 Unrealised fair value gains/ (losses) on economic hedges that do not qualify for hedge accounting $43 million reduction The unrealised fair value loss on hedges of accrual accounted term funding transactions for the year was $43 million. This represents a timing difference for the statutory results but does not affect profits over the life of the hedge. Net ineffectiveness on qualifying hedges $13 million reduction The net ineffectiveness on qualifying hedges of $13 million for the period arises from the fair value movement in these hedges which reverses over time and therefore does not affect profits over time. Total Notable Items $56 million reduction Details of Notable Items (post tax) impacting on 2024 results are presented below: 2024 Unrealised fair value gains/ (losses) on economic hedges that do not qualify for hedge accounting $128 million reduction The unrealised fair value loss on hedges of accrual accounted term funding transactions for the year was $128 million. This represents a timing difference for the statutory results but does not affect profits over the life of the hedge. Net ineffectiveness on qualifying hedges $5 million benefit The net ineffectiveness on qualifying hedges of $5 million for the period arises from the fair value movement in these hedges which reverses over time and therefore does not affect profits over time.

Net ineffectiveness on qualifying hedges $66 million benefit The net ineffectiveness on qualifying hedges of $66 million for the period arises from the fair value movement in these hedges which reverses over time and therefore does not affect profits over time. Total Notable Items $173 million reduction

312 WESTPAC GROUP 2025 ANNUAL REPORT SHAREHOLDER INFORMATION Exchange controls and other limitations affecting security holders Exchange controls and other limitations affecting security holders Australian exchange controls Australian laws control and regulate or permit the control and regulation of a broad range of payments and transactions involving non-residents of Australia. Pursuant to a number of exemptions, authorities and approvals, there are no general restrictions from transferring funds from Australia or placing funds to the credit of non-residents of Australia. However, Australian foreign exchange controls are implemented from time to time against prescribed countries, entities and persons. At the present time, these include: (a) withholding taxes in relation to remittances or dividends (to the extent they are unfranked) and interest payments; (b) the financial sanctions administered by the Department of Foreign Affairs and Trade (DFAT) in accordance with the Autonomous Sanctions Act 2011 (Cth) and the Autonomous Sanctions Regulations 2011, specifically, in relation to transactions involving the transfer of funds or payments to, by the order of, or on behalf of individuals or entities designated by the Minister of Foreign Affairs as published on the DFAT Sanctions Webpage (https://www.dfat.gov.au/ international-relations/security/sanctions); (c) the United Nations Security Council (UNSC) financial sanctions administered by DFAT, including: – Terrorist Asset Freezing Regime In accordance with the Charter of the United Nations Act 1945 (Cth) and the Charter of the United Nations (Dealings with Assets) Regulations 2008, a person is prohibited from using or dealing with funds, financial assets or economic resources of persons or entities listed as terrorists by the Minister for Foreign Affairs in the Commonwealth of Australia Gazette. It is also a criminal offence to make assets available to such persons or entities; and – Country-based sanctions Under the Charter of the United Nations Act 1945 and associated regulations, UNSC financial sanctions have been implemented. It is an offence to use or deal with funds, financial assets or economic resources of certain persons or entities associated with countries designated by the UNSC. It is also a criminal offence to make assets available to such persons or entities. Limitations affecting security holders The following Australian laws impose limitations on the right of non-residents or non-citizens of Australia to hold, own or vote Westpac shares. Foreign Acquisitions and Takeovers Act 1975 Acquisitions of interests in shares in Australian companies by foreign persons that meet certain thresholds are required to be notified to the Treasurer of Australia (through the Foreign Investment Review Board) and to obtain a no objections notification under the Foreign Acquisitions and Takeovers Act 1975 (Cth). That legislation applies to any acquisition by a foreign person, including a corporation or group of associated foreign persons, which results in ownership of 20% or more of the issued shares of an Australian company or the ability to control 20% or more of the total voting power. In addition, the legislation applies to any acquisition by a foreign government investor of 10% or more of the total voting power or ownership of an Australian company (or any interest if the foreign government investor acquires any control or influence– for example the right to appoint a director). Further, this lower 10% or control/influence threshold also applies to any acquisition by a foreign person, including a corporation or group of associated foreign persons, insofar as Westpac Banking Corporation owns or operates a critical banking asset as defined in the Security of Critical Infrastructure Act 2018 (Cth). The legislation requires any persons proposing to make any such acquisition to first notify the Treasurer of their intention to do so. Where such an acquisition has already occurred in the absence of a no objections notification, the Treasurer has the power to order divestment if he considers the acquisition to be contrary to Australia’s national interest. Financial Sector (Shareholdings) Act 1998 The Financial Sector (Shareholdings) Act 1998 (Cth) imposes restrictions on shareholdings in Australian financial sector companies (which includes Westpac). Under that legislation a person (including a corporation) may not hold more than a 20% ‘stake’ in a financial sector company without prior approval from the Treasurer of Australia. A person’s stake in a financial sector company is equal to the aggregate of the person’s voting power in the company and the voting power of the person’s associates. The concept of voting power is broadly defined. The Treasurer may approve a higher percentage stake if the Treasurer is satisfied that it is in the national interest to do so. In addition, even if a person’s stake in a financial sector company does not exceed the 20% limit, the Treasurer has the power to declare that a person has ‘practical control’ of a financial sector company and require the person to relinquish that control or reduce their stake in that company. Corporations Act 2001 The Corporations Act 2001 (Cth) prohibits any person (including a corporation) from acquiring a relevant interest in our voting shares if, after the acquisition, that person or any other person would be entitled to exercise more than 20% of the voting power in our shares. The prohibition is subject to certain limited exceptions. In addition, under the Corporations Act, a person is required to give a notice to us and to the ASX providing certain prescribed information, including their name, address and details of their relevant interests in our voting shares if they begin to have, or cease to have, a substantial holding in us, or if they already have a substantial holding and there is a movement of at least 1% in their holding. Such notice must, generally, be provided within two business days after the person becomes aware of that information. A person will have a substantial holding if the total votes attached to our voting shares in which they or their associates have relevant interests is 5% or more of the total number of votes attached to all our voting shares.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 313 Exchange controls and other limitations affecting security holders (Continued) The concepts of ‘associate’ and ‘relevant interest’ are broadly defined in the Corporations Act and investors are advised to seek their own advice on their scope. In general terms, a person will have a relevant interest in a share if they: (a) are the holder of that share; (b) have power to exercise, or control the exercise of, a right to vote attached to that share; or (c) have power to dispose of, or control the exercise of a power to dispose of, that share. It does not matter how remote the relevant interest is or how it arises. If two or more persons can jointly exercise any one of these powers, each of them is taken to have that power. Nor does it matter that the power or control is express or implied, formal or informal, exercisable either alone or jointly with someone else. Enforceability of foreign judgments in Australia We are an Australian public corporation with limited liability. All of our Directors and Executive Officers reside outside the US. Substantially all or a substantial portion of the assets of all or many of such persons are located outside the US. As a result, it may not be possible for investors to effect service of process within the US upon such persons or to enforce against them judgments obtained in US courts predicated upon the civil liability provisions of the federal securities laws of the US. There may be doubt as to the enforceability in Australia, in original actions or in actions for enforcement of judgments of US courts, of civil liabilities predicated upon the federal securities laws of the US. Taxation Taxation Australian taxation The following discussion is a summary of certain Australian taxation implications of the ownership and disposition of ordinary shares for shareholders holding their shares on capital account. This discussion is based on the laws in force at the date of the Annual Report and the Convention between the Government of Australia and the Government of the United States of America for the Avoidance of Double Taxation and The Prevention of Fiscal Evasion with Respect to Taxes on Income (the Tax Treaty), and is subject to any changes in Australian law and any change in the Tax Treaty occurring after that date. This discussion is intended only as a descriptive summary and does not purport to be a complete analysis of all the potential Australian tax implications of owning and disposing of ordinary shares. The specific tax position of each investor will determine the applicable Australian income tax implications for that investor and we recommend that investors consult their own tax advisers concerning the implications of owning and disposing of ordinary shares. Taxation of dividends Under the Australian dividend imputation system, Australian tax paid at the company level is imputed (or allocated) to shareholders by means of imputation credits (also called franking credits) which attach to dividends paid by the company to the shareholder. Such dividends are termed ‘franked dividends’. When an Australian resident individual shareholder receives a franked dividend, the shareholder may be entitled, depending upon their particular circumstances, to a tax offset to the extent of the franking credits, which may be offset against the Australian income tax payable by the shareholder. An Australian resident shareholder may, in certain circumstances, be entitled to a refund of excess tax offsets. The extent to which a dividend is franked typically depends upon a company’s available franking credits at the time of payment of the dividend. Accordingly, a dividend paid to a shareholder may be wholly or partly franked or wholly unfranked. Fully franked dividends paid to non-resident shareholders are exempt from Australian dividend withholding tax. Dividends paid to a non-resident shareholder which are not fully franked are subject to dividend withholding tax at the rate of 30% (unless reduced by a double tax treaty) to the extent they are unfranked. In the case of residents of the US who are entitled to the benefits of the Tax Treaty and are beneficially entitled to the dividends, the rate is reduced to 15% under the Tax Treaty, provided the shares are not effectively connected with a permanent establishment or a fixed base of the non-resident in Australia through which the non-resident carries on business in Australia or provides independent personal services. In the case of residents of the US that have a permanent establishment or fixed base in Australia where the shares in respect of which the dividends are paid are attributable to that permanent establishment or fixed base, there is no dividend withholding tax. Rather, such dividends will be taxed on a net assessment basis and, where the dividends are franked, entitlement to a tax offset may arise. Fully franked dividends paid to non-resident shareholders and dividends that have been subject to dividend withholding tax should not be subject to any further Australian income tax. There are circumstances where a shareholder may not be entitled to the benefit of franking credits. The application of these rules depends upon the shareholder’s own circumstances, including the period during which the shares are held and the extent to which the shareholder is ‘at risk’ in relation to their shareholding. Gain or loss on disposition of shares Generally, any profit made by a resident shareholder on disposal of shares will be subject to capital gains tax. However, if the shareholder is regarded as a trader or speculator, or carries on a business of investing for profit, any profits may be taxed as ordinary income. A discount may be available on capital gains on shares held for 12 months or more by Australian resident individuals, trusts or complying superannuation entities. The discount is one half for individuals and trusts, and one third for complying superannuation entities. Companies

For shares acquired prior to 21 September 1999, an alternative basis of calculation of the capital gain may be available which allows the use of an indexation formula. Normal rates of income tax would apply to capital gains so calculated. Any capital loss can only be offset against capital gains. Excess capital losses may be able to be carried forward for offset against future capital gains. Generally, subject to two exceptions, a non-resident disposing of shares in an Australian public company who holds those shares on capital account will be free from income tax in Australia. The main exceptions are: • shares held as part of a trade or business conducted through a permanent establishment in Australia. In such a case, any profit on disposal would be assessable to tax. Losses may give rise to capital losses or be otherwise deductible; and • shares held in companies where the shareholder and its associates have held at the time of disposal (or at least 12 months in the 24 months prior to disposal) a holding of 10% or more in the company and more than 50% of the company’s assets are represented by interests in Australian real property (which is unlikely to be the case for Westpac). In such a case, capital gains tax would apply. United States taxation The following discussion is a summary of certain US federal income tax implications of the ownership and disposition of ordinary shares by US holders (as defined below) that hold the ordinary shares as capital assets. This discussion is based on the US Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations, published rulings and court decisions, and the Tax Treaty, all as currently in effect and all of which are subject to change, possibly on a retroactive basis. This discussion is intended only as a descriptive summary. It does not purport to be a complete analysis of all the potential US federal income tax consequences of owning and disposing of ordinary shares and does not address US federal income tax considerations that may be relevant to US holders subject to special treatment under US federal income tax law (such as banks, insurance companies, real estate investment trusts, regulated investment companies, dealers in securities, brokers, tax-exempt entities, retirement plans, certain former citizens or residents of the US, persons holding ordinary shares as part of a straddle, hedge, conversion or other integrated transaction, persons that have a ‘functional currency’ other than the US dollar, persons that own 10% or more (by vote or value) of our stock, persons that generally mark their securities to market for US federal income tax purposes or persons that receive ordinary shares as compensation). As this is a complex area, we recommend investors consult their own tax advisers concerning the US federal, state and/or local implications of owning and disposing of ordinary shares. For the purposes of this discussion you are a US holder if you are a beneficial owner of ordinary shares and you are for US federal income tax purposes: • an individual who is a citizen or resident of the US; • a corporation created or organised in or under the laws of the US or any state thereof or the District of Columbia; • an estate, the income of which is subject to US federal income taxation regardless of its source; or • a trust, if a US court can exercise primary supervision over the trust’s administration and one or more US persons are authorised to control all substantial decisions of the trust, or certain electing trusts that were in existence on 19 August 1996 and were treated as domestic trusts on that date. If an entity treated as a partnership for US federal income tax purposes owns the ordinary shares, the US federal income tax implications of the ownership and disposition of ordinary shares will generally depend upon the status and activities of such partnership and its partners. Such an entity should consult its own tax adviser concerning the US federal income tax implications to it and its partners of owning and disposing of ordinary shares. Taxation of dividends If you are a US holder, you must include in your income as a dividend, the gross amount of any distributions paid by us out of our current or accumulated earnings and profits (as determined for US federal income tax purposes) without reduction for any Australian tax withheld from such distribution. We have not maintained and do not plan to maintain calculations of earnings and profits for US federal income tax purposes, and as a result, you may need to include the entire amount of any distribution in income as a dividend. If you are a non-corporate US holder, dividends paid to you that constitute qualified dividend income may be taxable to you at a preferential tax rate so long as certain holding period and other requirements are met. Dividends we pay with respect to the ordinary shares generally will be qualified dividend income so long as we are not a passive foreign investment company (PFIC) during the taxable year in which the dividend is paid or the preceding taxable year. Each non-corporate US holder should consult their own tax advisor regarding the possible applicability of the reduced tax rate and the related restrictions and special rules. Dividends paid by us constitute ordinary income that must generally be included in income when actually or constructively received. Such dividends will not be eligible for the dividends-received deduction generally allowed to corporate shareholders with respect to dividends received from US corporations. The amount of the dividend that you must include in your income as a US holder will be the US dollar value of the Australian dollar payments made, determined at the spot Australian dollar/US dollar rate on the date the dividend distribution is included in your income, regardless of whether the payment is in fact converted into US dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date you include the dividend payment in income to the date you convert the payment into US dollars will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income. This gain or loss generally will be income from sources within the US for foreign tax

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 315 Taxation (Continued) credit limitation purposes. Distributions on an ordinary share in excess of current and accumulated earnings and profits, as determined for US federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your basis in such ordinary share and thereafter as capital gain. Subject to certain limitations, Australian tax withheld in accordance with the Tax Treaty and paid over to Australia may be claimed as a foreign tax credit against your US federal income tax liability. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to a preferential tax rate. A US holder that does not elect to claim a US foreign tax credit for Australian income tax withheld may instead claim a deduction for such withheld tax, but only for a taxable year in which the US holder elects to do so with respect to all non-US income taxes paid or accrued in such taxable year. Dividends paid by us generally will be income from sources outside the US for foreign tax credit limitation purposes. Under the foreign tax credit rules, dividends may, depending on your circumstances, generally be ‘passive category’ or ‘general category’ income for purposes of computing the foreign tax credit. The rules relating to US foreign tax credits are very complex, and each US holder should consult its own tax adviser regarding the application of such rules. Taxation of capital gains If you sell, exchange or otherwise dispose of your ordinary shares, you will generally recognise a capital gain or loss for US federal income tax purposes equal to the difference between the US dollar value of the amount that you realise and your tax basis, determined in US dollars, in your ordinary shares. A capital gain of a non-corporate US holder is generally taxed at a reduced rate if the holder has a holding period greater than one year. The deductibility of capital losses is subject to limitations. Such capital gain or loss generally will be income from sources within the US, for foreign tax credit limitation purposes. Medicare tax In addition to regular US federal income tax, certain US holders that are individuals, estates or trusts are subject to a 3.8% tax on all or a portion of their ‘net investment income’, which may include all or a portion of their dividend income and net gain from the sale, exchange or other disposition of their ordinary shares. Passive foreign investment company considerations We believe that we will not be treated as a passive foreign investment company (PFIC) for US federal income tax purposes, and this discussion assumes we are not a PFIC. However, the determination as to whether we are a PFIC is made annually at the end of each taxable year and therefore could change. If we were to be treated as a PFIC, a US holder of ordinary shares could be subject to certain adverse tax consequences. Disclosure requirements for specified foreign financial assets Individual US holders (and certain US entities specified in US Internal Revenue Service (IRS) guidance) who, during any taxable year, hold any interest in any specified foreign financial asset, generally will be required to file with their US federal income tax returns certain information on IRS Form 8938 if the aggregate value of all such assets exceeds certain specified amounts. ‘Specified foreign financial asset’ generally includes any financial account maintained with a non-US financial institution and may also include the ordinary shares if they are not held in an account maintained with a financial institution. Substantial penalties may be imposed, and the period of limitations on assessment and collection of US federal income taxes may be extended, in the event of a failure to comply. US holders should consult their own tax advisers as to the possible application to them of this filing requirement. Information reporting and backup withholding Under certain circumstances, information reporting and/or backup withholding may apply to US holders with respect to payments on or the proceeds from the sale, exchange or other disposition of the ordinary shares, unless an applicable exemption is satisfied. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or credit against a US holder’s US federal income tax liability if the required information is furnished by the US holder on a timely basis to the IRS.

316 WESTPAC GROUP 2025 ANNUAL REPORT SHAREHOLDER INFORMATION Our constitution Our constitution Overview We were incorporated in 1850 under the Bank of New South Wales Act 1850 (NSW), a special piece of legislation passed by the New South Wales Parliament at a time when there was no general companies’ legislation in Australia. On 23 August 2002, Westpac became registered under the Corporations Act 2001 (Cth) (Corporations Act) as a public company limited by shares. As part of the process of becoming a company regulated under the Corporations Act, shareholders adopted a new constitution at the AGM on 15 December 2000, which came into operation on 23 August 2002. Our constitution has been subsequently amended by shareholders on 15 December 2005, 13 December 2007, 13 December 2012 and 15 December 2021. Our objects and purposes Our constitution does not contain a statement of our objects and purposes. As a company regulated by the Corporations Act, we have the legal capacity and powers of an individual both within and outside Australia, and all the powers of a body corporate, including the power to issue and cancel shares, to issue debentures, to distribute our property among our equity holders (either in kind or otherwise), to give security by charging our uncalled capital, to grant a floating charge over our property and to do any other act permitted by any law. Directors’ voting powers Under clause 9.11(a) of our constitution, subject to complying with the Corporations Act regarding disclosure of and voting on matters involving material personal interests, our Directors may: 1. hold any office or place of profit in our company, except that of auditor; 2. hold any office or place of profit in any other company, body corporate, trust or entity promoted by our company or in which it has an interest of any kind; 3. enter into any contract or arrangement with our company; 4. participate in any association, institution, fund, trust or scheme for past or present employees or Directors of our company or persons dependent on or connected with them; 5. act in a professional capacity (or be a member of a firm that acts in a professional capacity) for our company, except as auditor; and 6. participate in, vote on and be counted in a quorum for any meeting, resolution or decision of the Directors and be present at any meeting where any matter is being considered by the Directors. Under clause 9.11(b) of our constitution, a Director may do any of the above despite the fiduciary relationship of the Director’s office: 1. without any liability to account to our company for any direct or indirect benefit accruing to the Director; and 2. without affecting the validity of any contract or arrangement. Under the Corporations Act, however, a Director who has a material personal interest in any matter to be considered at any Board meeting must not be present while the matter is being considered or vote on the matter, unless the other Directors resolve to allow that Director to be present and vote or a declaration is made by ASIC permitting that Director to participate and vote. These restrictions do not apply to a limited range of matters set out in section 191(2) of the Corporations Act, where the Director’s interest: 1. arises because the Director is a shareholder of the company and is held in common with other shareholders; 2. arises in relation to the Director’s remuneration as a Director of the company; 3. relates to a contract the company is proposing to enter into that is subject to shareholder approval and will not impose obligations on the company if not approved by shareholders; 4. arises merely because the Director is a guarantor or has given an indemnity or security for all or part of a loan (or proposed loan) to the company; 5. arises merely because the Director has a right of subrogation in relation to a guarantee or indemnity referred to in (d); 6. relates to a contract that insures, or would insure, the Director against liabilities the Director incurs as an officer of the company (but only if the contract does not make the company or related body corporate the insurer); 7. relates to any payment by the company or a related body corporate in respect of certain indemnities permitted by the Corporations Act or any contract relating to such an indemnity; or 8. is in a contract or proposed contract with, or for the benefit of, or on behalf of, a related body corporate and arises merely because the Director is a Director of that related body corporate. If there are not enough Directors to form a quorum for the Board meeting because of Directors’ interests in a particular matter, a general meeting for shareholders may be called to consider the matter and interested Directors are entitled to vote on any proposal to requisition such a meeting. Under clause 9.7 of our constitution, the maximum aggregate amount of annual remuneration to be paid to our Non-Executive Directors must be approved by our shareholders. This aggregate amount is paid to the Non-Executive Directors in such manner as the Board from time to time determines. Directors’ remuneration is one of the exceptions under section 191 of the Corporations Act to the prohibitions against being present and voting on any matter in which a Director has a material personal interest. Directors’ borrowing powers Clause 10.2 of our constitution empowers our Directors, as a Board, to exercise all the powers of Westpac to borrow or raise money, to charge any property or business of Westpac or all or any of its uncalled capital and to issue debentures or give any other security for a

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 317 Our constitution (Continued) debt, liability or obligation of Westpac or of any other person. Such powers may only be changed by amending the constitution, which requires a special resolution (that is, a resolution passed by at least 75% of the votes cast by members entitled to vote on the resolution and for which notice has been given in accordance with the Corporations Act). Minimum number of Directors Our constitution requires that the minimum number of Directors is determined in accordance with the Corporations Act or other regulations. Currently the Corporations Act prescribes three as a minimum number of Directors for a public company and APRA governance standards specify five as the minimum number of Directors for APRA regulated entities. Westpac’s current number of Directors is above these prescribed minimums. Share rights The rights attaching to our ordinary shares are set out in the Corporations Act and in our constitution, and may be summarised as follows: a. Profits and dividends Holders of ordinary shares are entitled to receive such dividends on those shares as may be determined by our Directors from time to time. Dividends that are paid but not claimed may be invested by our Directors for the benefit of Westpac until claimed or required to be dealt with in accordance with any law relating to unclaimed monies. Under the Corporations Act, Westpac must not pay a dividend unless our assets exceed our liabilities immediately before the dividend is declared and the excess is sufficient for payment of the dividend. In addition, the payment must be fair and reasonable to the company’s shareholders as a whole and must not materially prejudice our ability to pay our creditors. Subject to the Corporations Act, the constitution, the rights of persons (if any) entitled to shares with special rights to a dividend and any contrary terms of issue of or applying to any shares, our Directors may determine that a dividend is payable, fix the amount and the time for payment and authorise the payment or crediting by Westpac to, or at the direction of, each shareholder entitled to that dividend. If any dividends are returned unclaimed, we are generally obliged, under the Banking Act 1959 (Cth) (Banking Act), to hold those amounts as unclaimed monies for a period of seven years. If at the end of that period the monies remain unclaimed by the shareholder concerned, we must submit an annual unclaimed money return to ASIC by 31 March each year containing the unclaimed money as at 31 December of the previous year. Upon such payment being made, we are discharged from further liability in respect of that amount. Our Directors may, before paying any dividend, set aside out of our profits such sums as they think proper as reserves, to be applied, at the discretion of our Directors, for any purpose for which the profits may be properly applied. Our Directors may carry forward so much of the profits remaining as they consider ought not to be distributed as dividends without transferring those profits to a reserve. The following additional restrictions apply to our ability to declare and/or pay dividends: 1. if the payment of the dividend would breach or cause a breach by us of applicable capital adequacy or other supervisory requirements of APRA, including where Westpac’s Common Equity Tier 1 Capital Ratio falls within APRA’s capital conservation buffer range (consisting of the capital conservation buffer plus any countercyclical capital buffer, currently 5.75% of risk-weighted assets). Currently, one such requirement is that a dividend should not be paid without APRA’s prior consent if payment of that dividend, after taking into account all other dividends (if any) paid on our shares and payments on more senior capital instruments, in the preceding 12 consecutive months to which they relate, would cause the aggregate of such dividend payments to exceed our after tax earnings for the preceding 12 consecutive months, as reflected in our relevant audited consolidated financial statements; and 2. if, under the Banking Act, we are directed by APRA not to pay a dividend; 3. if the declaration or payment of the dividend would result in us becoming insolvent; or 4. if any interest payment, dividend or distribution on certain Additional Tier 1 securities issued by us is not paid in accordance with the terms of those securities, we may be restricted from declaring and/or paying dividends on ordinary shares. This restriction is subject to a number of exceptions. b. Voting rights Holders of our fully paid ordinary shares have, at general meetings, one vote on a show of hands and, upon a poll, one vote for each fully paid share held by them. c. Voting and re-election of Directors Under our constitution, each Director, apart from the Managing Director, must not hold office without re-election past the third AGM following the Director’s appointment or last election, whichever is longer. A retiring Director holds office until the conclusion of the meeting at which that Director retires but is eligible for re-election at that meeting. In addition, there must be an election of Directors at each AGM. This is consistent with the requirements of the ASX Listing Rules. Under the Corporations Act, the election or re-election of each Director by shareholders at a general meeting of a public company must proceed as a separate item, unless the shareholders first resolve that the elections or re-elections may be voted on collectively. A resolution to allow collective voting in relation to elections or re-elections is effective only if no votes are cast against that resolution. Any resolution electing or re-electing two or more Directors in contravention of this requirement is void. d. Winding up Subject to any preferential entitlement of holders of preference shares on issue at the relevant time, holders

318 WESTPAC GROUP 2025 ANNUAL REPORT SHAREHOLDER INFORMATION Our constitution (Continued) of our ordinary shares are entitled to share equally in any surplus assets if we are wound up. e. Sinking fund provisions We do not have any class of shares on issue that is subject to any sinking fund provisions. Variation of rights attaching to our shares Under the Corporations Act, unless otherwise provided by the terms of issue of a class of shares, the terms of issue of a class of shares in Westpac can only be varied or cancelled in any way by a special resolution of Westpac and with either the written consent of our shareholders holding at least 75% of the votes in that class of shares or with the sanction of a special resolution passed at a separate meeting of the holders of that class of shares. Convening general meetings Under our constitution, our Directors may convene and arrange to hold a general meeting of Westpac whenever they think fit and must do so if required to do so under the Corporations Act and ASX Listing Rules. Under the Corporations Act, our Directors must call and arrange to hold a general meeting of Westpac if requested to do so by our shareholders who hold at least 5% of the votes that may be cast at the general meeting. Shareholders who hold at least 5% of the votes that may be cast at a general meeting may also call and arrange to hold a general meeting of Westpac at their own expense. At least 28 days notice must be given of a meeting of our shareholders. Written notice must be given to all shareholders entitled to attend and vote at the meeting. All ordinary shareholders are entitled to attend and, subject to the constitution and the Corporations Act, to vote at general meetings of Westpac. Limitations on securities ownership A number of limitations apply in relation to the ownership of our shares, and these are described in more detail in the section ‘Limitations affecting security holders’. Change in control restrictions Restrictions apply under the Corporations Act, the Financial Sector (Shareholdings) Act 1998 (Cth) and the Foreign Acquisitions and Takeovers Act 1975 (Cth). For more detailed descriptions of these restrictions, refer to the sections ‘Limitations affecting security holders’, ‘Foreign Acquisitions and Takeovers Act 1975’, ‘Financial Sector (Shareholdings) Act 1998’, and ‘Corporations Act 2001’. Substantial shareholder disclosure There is no provision in our constitution that requires a shareholder to disclose the extent of their ownership of our shares. Under the Corporations Act, however, any person who begins or ceases to have a substantial holding of our shares must notify us within two business days after they become aware of that information. A further notice must be given to us if there is an increase or decrease of 1% in a person’s substantial holding. Copies of these notices must also be given to the ASX. A person has a substantial holding of our shares if the total votes attached to our voting shares in which they or their associates have relevant interests is 5% or more of the total number of votes attached to all our voting shares. For more details, refer to the section ‘Corporations Act 2001’. We also have a statutory right under the Corporations Act to trace the beneficial ownership of our shares by giving a direction to a shareholder, or certain other persons, requiring disclosure to us of, among other things, their own relevant interest in our shares and the name and address of each other person who has a relevant interest in those shares, the nature and extent of that interest and the circumstances that gave rise to that other person’s interest. Such disclosure must, except in certain limited circumstances, be provided within two business days after the direction is received. Australian Company and Business Numbers All Australian companies have a unique nine-digit identifier, referred to as an Australian Company Number (ACN), which must be included on public documents, eligible negotiable instruments and the company’s common seal. In addition, entities can apply for registration on the Australian Business Register and be allocated a unique eleven-digit identifier known as an Australian Business Number (ABN). For Australian companies, the last nine digits of their ABN are identical to their ACN. The ABN may be quoted on documents in lieu of the ACN. Our ACN is 007 457 141 and our ABN is 33 007 457 141. Documents on display We are subject to the disclosure requirements of the US Securities Exchange Act of 1934, as amended. In accordance with these requirements, we file Annual Reports with, and furnish other information to, the US Securities & Exchange Commission (SEC). The SEC also maintains a website at www.sec.gov that contains reports, proxy statements and other information regarding registrants that file electronically with the SEC. Since April 2002, we have filed our reports on Form 20-F and have furnished other information to the SEC in electronic format which may be accessed through this website.

SOx is a wide ranging piece of US legislation concerned largely with financial reporting and corporate governance. We are obligated to comply with SOx by virtue of being a foreign registrant with the SEC and we have established procedures designed to comply with all applicable requirements of SOx. Disclosure controls and procedures Our management, with the participation of our CEO and CFO, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the US Securities Exchange Act of 1934) as of 30 September 2025. Based upon this evaluation, our CEO and CFO have concluded that the design and operation of our disclosure controls and procedures were effective as of 30 September 2025. Management’s report on internal control over financial reporting Rule 13a-15(a) under the US Securities Exchange Act of 1934 requires us to maintain an effective system of internal control over financial reporting. Refer to the sections headed ‘Management’s report on internal control over financial reporting’ and ‘Report of independent registered public accounting firm’ in Section 3 for those reports. Changes in our internal control over financial reporting There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) of the US Securities Exchange Act of 1934) for the year ended 30 September 2025 that has been identified and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 1.

FINANCIAL REPORT EXHIBITS INDEX STRATEGIC REVIEW PERFORMANCE REVIEW EXHIBIT 15.4 ADDITIONAL INFORMATION 325 Capital Adequacy Australian Prudential Regulation Authority (APRA) leverage ratio The leverage ratio is defined by APRA as Tier 1 capital divided by the “Exposure measure” and is expressed as a percentage. “Exposure measure” includes on-balance sheet exposures, derivatives exposures, securities financing transaction (SFT) exposures, and other off-balance sheet exposures. Common equity tier 1 (CET1) capital ratio Common equity tier 1 (CET1) capital divided by risk weighted assets, as defined by APRA. Credit risk weighted assets (Credit RWA) Credit risk weighted assets represent risk weighted assets (on-balance sheet and off-balance sheet) that relate to credit exposures and therefore exclude market risk, operational risk and IRRBB. Internationally comparable capital ratios Internationally comparable methodology references the ABA study on the comparability of APRA’s capital framework released on 10 March 2023. Operational risk The risk of loss resulting from inadequate or failed internal processes, people and systems or from external events, including legal risk but excluding strategic or reputational risk. Risk weighted assets (RWA) Assets (both on and off-balance sheet) are risk weighted according to each asset’s inherent potential for default and what the likely losses would be in case of default. In the case of non-asset backed risks (i.e. market, IRRBB and operational risk), RWA is determined by multiplying the capital requirements for those risks by 12.5. Tier 1 capital ratio Total Tier 1 capital divided by risk weighted assets, as defined by APRA. Total capital ratio Total capital divided by risk weighted assets, as defined by APRA. Funding and liquidity Deposit to loan ratio Customer deposits divided by loans. Funding for Lending Programme (FLP) A facility that was established by the RBNZ in December 2020 to provide 3 year term funding to eligible New Zealand institutions via repurchase transactions, subject to qualifying conditions, to help support lending to New Zealand customers. The facility closed to new draw downs in December 2022. High Quality Liquid Assets (HQLA) Assets which meet APRA’s criteria for inclusion as HQLA in the numerator of the LCR. Liquid assets HQLA and non LCR qualifying liquid assets, but excludes internally securitised assets that are eligible for a repurchase agreement with the RBA and the RBNZ. Liquidity Coverage Ratio (LCR) An APRA requirement to maintain an adequate level of unencumbered high quality liquid assets, to meet liquidity needs for a 30 calendar day period under an APRA-defined severe stress scenario. Absent a situation of financial stress, the value of the LCR must not be less than 100%. LCR is calculated as the percentage ratio of stock of HQLA, and qualifying RBNZ securities over the total net cash out-flows in a modelled 30 day defined stressed scenario. Net Stable Funding Ratio (NSFR) The NSFR is defined as the ratio of the amount of available stable funding (ASF) to the amount of required stable funding (RSF) defined by APRA. The amount of ASF is the portion of an ADI’s capital and liabilities expected to be a reliable source of funds over a one year time horizon. The amount of RSF is a function of the liquidity characteristics and residual maturities of an ADI’s assets and off-balance sheet activities. ADIs must maintain an NSFR of at least 100%. Term funding from central banks Term funding from central banks includes the drawn balances of the RBNZ FLP and Term Lending Facility. Wholesale funding Wholesale funding includes debt issues, loan capital, certificates of deposit, term funding from central banks and interbank placements. Credit quality Collectively assessed provisions (CAPs) Collectively assessed provisions for expected credit loss under AASB 9 represent the Expected Credit Loss (ECL) which is collectively assessed in pools of similar assets with similar risk characteristics. This incorporates forward-looking information and does not require an actual loss event to have occurred for an impairment provision to be recognised. Default Credit exposures that are non-performing. Exposure at default (EAD) EAD is calculated at facility level and includes outstandings as well as the proportion of committed undrawn that is expected to be drawn in the event of a future default. Impaired exposures Includes exposures that have deteriorated to the point where full collection of interest and principal is in doubt, based on an assessment of the customer’s outlook, cash flow, and the net realisation of value of assets to which recourse is held: • Facilities 90 days or more past due, and full recovery is in doubt: exposures where contractual payments are 90 or more days in arrears and the net realisable value of assets to which recourse is held may not be sufficient to allow full collection of interest and principal, including overdrafts or other revolving facilities that remain continuously outside approved limits by material amounts for 90 or more calendar days; • Non-accrual facilities: exposures with individually assessed impairment provisions held against them, excluding restructured loans; • Restructured facilities: exposures where the original contractual terms have been formally modified to provide for concessions of interest or principal for reasons related to the financial difficulties of the customer; • Other assets acquired through security enforcement (includes other real estate owned): includes the value of any other assets acquired as full or partial settlement of outstanding obligations through the enforcement of security arrangements; or • Any other facilities where the full collection of interest and principal is in doubt. Impaired exposures provisions to impaired exposures Impairment provisions relating to impaired exposures include individually assessed provisions plus the proportion of the collectively assessed provisions that relate to impaired exposures. Impairment charges/(benefit) to average loans Calculated as impairment charges/(benefit) (annualised where applicable) divided by average gross loans.

326 WESTPAC GROUP 2025 ANNUAL REPORT GLOSSARY OF ABBREVIATIONS AND DEFINED TERMS Credit quality Individually assessed provisions (IAPs) Provisions raised for losses on loans that are known to be impaired and are assessed on an individual basis. The estimated losses on these impaired loans is based on expected future cash flows discounted to their present value and, as this discount unwinds, interest will be recognised in the income statement. Loss given default (LGD) The loss that is expected to arise in the event of a default. Non-performing not impaired exposures Includes those credit exposures that are in default, but where it is expected that the full value of principal and accrued interest can be collected, generally by reference to the value of security held. Performing exposures Credit exposures that are not non-performing. Probability of default (PD) Probability of default is a through-the-cycle assessment of the likelihood of a customer defaulting on its financial obligations within one year. Provision for expected credit losses (ECL) Expected credit losses are a probability-weighted estimate of the cash shortfalls expected to result from defaults over the relevant time frame. They are determined by evaluating a range of possible outcomes and taking into account the time value of money, past events, current conditions and forecasts of future economic conditions. Stage 1: 12 months ECL - performing For financial assets where there has been no significant increase in credit risk since origination a provision for 12 months expected credit losses is recognised. Interest revenue is calculated on the gross carrying amount of the financial asset. Stage 2: Lifetime ECL - performing For financial assets where there has been a significant increase in credit risk since origination but where the asset is still performing a provision for lifetime expected losses is recognised. Interest revenue is calculated on the gross carrying amount of the financial asset. Stage 3: Lifetime ECL - non-performing For financial assets that are non-performing a provision for lifetime expected losses is recognised. Interest revenue is calculated on the carrying amount net of the provision for ECL rather than the gross carrying amount. Stressed exposures Watchlist and substandard credit exposures plus non-performing exposures. Total committed exposure (TCE) Represents the sum of the committed portion of direct lending (including funds placement overall and deposits placed), contingent and pre-settlement risk plus the committed portion of secondary market trading and underwriting risk. Watchlist and substandard Loan facilities where customers are experiencing operating weakness and financial difficulty but are not expected to incur loss of interest or principal.

Cybersecurity management and governance

The Group Chief Information Security Officer (CISO) reports to the Chief Information Officer, a member of the Executive Team. The CISO is a member of key cybersecurity governance forums and is responsible for leading and managing the cybersecurity function, setting the cybersecurity strategy and direction, and overseeing the implementation, operation and execution of the cybersecurity policies, standards, controls, and capabilities, including for third parties who are engaged to manage Westpac’s information assets.

We have implemented a range of cybersecurity processes, technologies, and controls to facilitate our efforts to assess, identify, and manage such risks, including regular network and endpoint monitoring, access controls, vulnerability assessments, penetration testing, annual information security training for employees, and tabletop cybersecurity incident response exercises.

We have an Incident Response Plan which guides the actions we are to take in the event of a suspected or confirmed cybersecurity incident. The plan includes processes to triage, investigate, contain, and remediate the incident. The plan is designed to contain and minimise the impact of a cybersecurity incident on our customers. We also maintain a Business Continuity Plan, which provides procedures for maintaining the continuity of critical business processes in the event of business interruption, including any that involve cybersecurity incidents which may significantly impact our operations.

Our cybersecurity team is informed about and monitors the prevention, mitigation, detection and remediation of cybersecurity threats through their management of, and participation in, the strategy processes.

The CISO and the cybersecurity team have relevant expertise and experience in various aspects of cybersecurity, such as strategy, governance, risk management, threat intelligence, incident response, security operations, architecture, engineering, testing and awareness. The CISO has extensive experience in information technology and cybersecurity. The cybersecurity team consists of qualified and competent professionals who have diverse backgrounds and skills in cybersecurity. The cybersecurity team regularly participates in training, education, and development programs to enhance their knowledge and skills to keep up with the evolving cybersecurity landscape.

As part of its cybersecurity risk management, Westpac engages with third parties for independent reviews and assessments of its cybersecurity policies, standards, controls, and capabilities. These third parties include external auditors, industry bodies, consultants, and specialists. The purpose of these engagements is to obtain assurance, validation, benchmarking and improvement recommendations on Westpac's cybersecurity posture and maturity. Westpac holds ISO27001, PCI-DSS and SOC 2 Type 2 certifications for areas of the Group.

The CISO escalates key cybersecurity risk and control issues, as appropriate, to the Technology Risk Committee (TRC) or to the appropriate Line of Business and Divisional Committees. The TRC, a senior management committee, oversees the technology function and technology risk management. The TRC reports to the Group Executive Risk Committee (GRISKCO), the executive management committee responsible for overseeing the group's strategy, performance, and risk management.

The Board of Directors receives periodic updates from the CIO and the CISO regarding cybersecurity matters. The Board is ultimately responsible for the oversight of the cybersecurity risk management. The Board delegates some of its oversight responsibilities to the Board Risk Committee, which assists the Board in the oversight of cybersecurity risk management.

During the period covered by this 2025 Annual Report, we have not experienced any cybersecurity incidents which have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition. However, institutions like ours, as well as our employees, service providers and other third parties have experienced a significant increase in information security and cybersecurity risk in recent years and will likely continue to be the target of increasing sophisticated cyber-related attacks.
