The objective of this audit was to assess the Private Health Insurance Administration Council's (PHIAC's) administrative effectiveness as a regulator of private health insurance. In making this assessment, the Australian National Audit Office (ANAO) addressed the following criteria: whether PHIAC monitored compliance with its legislative requirements and analysed related data; whether PHIAC addressed and managed non-compliance with its legislative requirements; and whether PHIAC's governance and organisation supported the performance of its legislative functions. Although the Department of Health and Ageing (Health) also has a role in the regulation of the private health insurance industry under the National Health Act 1953 (Health Act), Health's regulatory activities were outside the scope of this audit.

The objective of the audit was to examine the effectiveness of the administration of the Gateway review process by Finance and FMA Act agencies.

• identify areas for improvement in the coordination, planning and practices employed in administration of tactical fighter operations.

The audit assessed the operations of the four Northern Territory Land Councils which provide a range of services to Aboriginal people under the Aboriginal Land Rights (Northern Territory) Act 1976. The audit also assessed the Aboriginal and Torres Strait Islander Commision's (ATSIC) administration of the Aboriginals Benefit Account, which provides funding to the Land Councils under the same Act. The objectives of the audit were to assess:

• whether the governance arrangements used by ATSIC and the Land Councils are appropriate;
• whether ATSIC meets its legislative requirements concerning the Aboriginals Benefit Account in an effective and efficient way; and
• whether the Land Councils are effective and efficient in managing their recourses to meet the objectives of the Aboriginal Land Rights (Northern Territory) Act 1976.

The objective of the audit was to assess if DBCDE had effectively managed the ABG program, and the extent to which the program was achieving its stated objectives. The audit examined DBCDE's activities supporting the planning, implementation, monitoring and performance reporting for the ABG program from its commencement in April 2007 to June 2010.

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'.
