The Australian National Audit Office (ANAO) conducted 44 performance audits across the 2024–25 financial year to provide independent and objective assessments of all or part of an entity’s operations. This report presents themes and insights from the 2024–25 performance audit program, as well as analysis of the outcomes of performance audits between 2020–21 and 2024–25.

The audit objective was to assess the Australian Taxation Office’s effectiveness in managing complaints.

The objective of the audit was to evaluate the Tax Office's corporate management of data matching, including analytics.

The ANAO examined the Tax Office's strategic goals and governance arrangements for data matching and analytics, its compliance with privacy requirements and whether the Tax Office is achieving intended results, which include revenue collection, optimised compliance and provision of improved services to taxpayers.

Tax Office executives have been increasingly drawing on the interrelationships and conceptual commonalities of Tax Office data matching and analytics activity. Accordingly, the audit included these relationships and conceptual commonalities within the scope of the audit. The audit was guided, therefore, by a broader definition of ‘data matching': meaning ‘finding relationships and patterns in large volumes of data'. This includes the more traditional idea of data matching as ‘bringing together data from different sources and comparing it'.

The objective of the audit was to assess whether the Office of the Registrar of Indigenous Corporations (ORIC) supports good governance in Indigenous corporations consistent with the Corporations (Aboriginal and Torres Strait Islander) Act 2006 (CATSI).

The audit assessed the effectiveness of the rural research and development corporations’ management of probity.

The objective of the audit was to assess whether Defence is effectively managing the EO Services Contract.

The audit focused mainly on Defence's contract management framework, including the arrangements to monitor the contractor’s performance in delivering services under the contract. The audit also examined the processes used by Defence to develop the current version of the contract and the extent to which the revised contract, as negotiated in 2006, provides an assurance of better value for money when compared to the original contract signed in 2001.

The objective of the audit was to assess the effectiveness of the governance board in the Australian Institute of Marine Science.

The objective of this audit was to assess whether Human Services has an effective high-level compliance strategy for administered payments made under the Centrelink and Medicare programs.
