Forward-looking statements appear in a number of places in this presentation and include statements regarding our intent, belief or current<br>expectations with respect to our business and operations, macro and micro economic and market conditions, results of operations and financial condition, capital adequacy, liquidity and risk management, including,<br>without limitation, future loan loss provisions and financial support to certain borrowers, forecasted economic indicators and performance metric outcomes, indicative drivers, climate- and other sustainability-related<br>statements, commitments, targets, projections and metrics, and other estimated and proxy data.<br>We use words such as ‘will’, ‘may’, ‘expect’, ‘intend’, ‘seek’, ‘would’, ‘should’, ‘could’, ‘continue’, ‘plan’, ‘estimate’, ‘anticipate’, ‘believe’, ‘probability’, ‘indicative’, ‘risk’, ‘aim’, ‘outlook’, ‘forecast’, ‘f’cast’, ‘f’, ‘assumption’,<br> ‘projection’, ‘target’, ‘goal’, ‘guidance’, ‘ambition’, ‘objective’, ‘pursue’ or other similar words to identify forward-looking statements, or otherwise identify forward-looking statements. These forward-looking statements<br>reflect our current views on future events and are subject to change, certain known and unknown risks, uncertainties and assumptions and other factors which are, in many instances, beyond our control (and the control<br>of our officers, employees, agents and advisors), and have been made based on management’s expectations or beliefs concerning future developments and their potential effect upon us.<br>Forward-looking statements may also be made, verbally or in writing, by members of Westpac’s management or Board in connection with this presentation. Such statements are subject to the same limitations,<br>uncertainties, assumptions and disclaimers set out in this presentation.<br>There can be no assurance that future developments or performance will align with our expectations or that the effect of future developments on us will be those anticipated. Actual results could differ materially from<br>those we expect or which are expressed or implied in forward-looking statements, depending on various factors including, but not limited to, those described in the sections titled ‘Operating Environment’ and ‘Risk<br>Management' in our 2025 Annual Report, as well as ‘2025 Risk Factors’ (each available at www.westpac.com.au). When relying on forward-looking statements to make decisions with respect to us, investors and others<br>should carefully consider such factors and other uncertainties and events.<br>Except as required by law, we assume no obligation to revise or update any forward-looking statements contained in this presentation, whether from new information, future events, conditions or otherwise, after the<br>date of this presentation.<br>We also make statements about our processes and policies (including what they are designed to do) as well as the availability of our systems or product features. Systems, processes and product features can be subject<br>to disruption, and may not always work as intended, so these statements are limited by the factors described in the section titled ‘Risk Management’ in our 2025 Annual Report, as well as ‘2025 Risk Factors’ (each<br>available at www.westpac.com.au).<br>34 Westpac Update March 2026<br>DISCLAIMER
