The group reported a loss for the year ended 30 June 2025 of $38,342,457 (30 June 2024: $47,949,119). The decreased loss for the comparative period is due to the decrease in fair value movements in contingent consideration and decrease in share-based payments during the year.

The group's net assets increased to $42,871,904 (30 June 2024: $27,353,286). This is primarily due to the increase in cash due to capital raises during the year and increase in trade and other receivables due to recognition of income associated with the tax incentive related to research and development activities during the financial year. As at 30 June 2025, the group had cash reserves of $29,116,835 (30 June 2024: $18,575,040).

(i) R&D tax incentive

The group's research and development activities are eligible under an Australian government tax incentive for eligible expenditure. Where expenditure is incurred outside of Australia, an 'overseas finding' must be obtained from AusIndustry prior to any such expenditure being eligible under the scheme. Management has assessed these activities and expenditure to determine which are likely to be eligible under the incentive scheme. Amounts are recognised when it has been established that the conditions of the tax incentive have been met and that the expected amount can be reliably measured. For the year ended 30 June 2025, the group has included an item in other income of $9,368,544 (2024: $1,292,578) to recognise income over the period necessary to match the grant on a systematic basis with the costs that they are intended to compensate. An additional of $3,587,887 of accrued income has been recognised for FY2024 as at 30 June 2025.
