Note 2. Critical accounting judgements, estimates and assumptions The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts in the financial statements. Management continually evaluates its judgements and estimates in relation to assets, liabilities, contingent liabilities, revenue and expenses. Management bases its judgements, estimates and assumptions on historical experience and on other various factors, including expectations of future events, management believes to be reasonable under the circumstances. The resulting accounting judgements and estimates will seldom equal the related actual results. The judgements, estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities (refer to the respective notes) within the next financial year are discussed below. Research and Development Rebate With the successful track record of the consolidated entity in obtaining the Research and Development rebate from the ATO, the estimated 2025 rebate for $2.8M has been accrued into income for the year ended 30 June 2025 (2024: $2.3M). The company is entitled to claim grant credits from the Australian Government in recompense for its research and development program expenditure. The program is overseen by AusIndustry, which is entitled to audit and/or review claim lodged for the past 4 years. In the event of a negative finding from such an audit or review AusIndustry has the right to rescind and clawback those prior claims, potentially with penalties. Such a finding may only occur in the event that those expenditures do not appropriately qualify for the grant program. In their estimation, considering also the independent external expertise they have contracted to draft and claim such expenditures, the directors of the company consider that such a negative review has a remote likelihood of occurring. Non-recognition of carried forward tax losses The balance of future income tax benefit arising from timing differences and carried-forward losses have not been recognised as an asset because recovery is not regarded as probable. The cumulative future income tax benefit which has not been recognised as an asset will only be obtained if: i. The Group derives future assessable income of a nature and amount sufficient to enable the benefit to be realised, ii. The Group continues to comply with the conditions for the deductibility imposed by law, and iii. No changes in tax legislation adversely affecting the Group realising the benefit. Fair value measurement hierarchy The consolidated entity is required to classify all assets and liabilities, measured at fair value, using a three level hierarchy, based on the lowest level of input that is significant to the entire fair value measurement, being: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date; Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and Level 3: Unobservable inputs for the asset or liability. Considerable judgement is required to determine what is significant to fair value and therefore which category the asset or liability is placed in can be subjective. The fair value of assets and liabilities classified as level 3 is determined by the use of valuation models. These include discounted cash flow analysis or the use of observable inputs that require significant adjustments based on unobservable inputs. The consolidated entity’s finance team performs valuations of financial items for financial reporting purposes, including Level 3 fair values, in consultation with third party valuation specialists for complex valuations. Valuation techniques are selected based on the characteristics of each instrument, with the overall objective of maximising the use of market-based information. Assessment of the conversion features of the convertible notes During the year ended 30 June 2025, the Company issued convertible notes with variable conversion clauses. At initial recognition an embedded derivative is recognised on the statement of financial position at fair value and that embedded derivative is subsequently recorded at its fair value thereafter, with changes in fair value going through to the statement of profit or loss and other comprehensive income. The difference between the consideration received (net of costs) and the embedded derivative is reflected in the principal value of the convertible note liability. Annual Report 2025 32
