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 the completeness and reliability of the estimates reported in Tax Expenditures Statement 2006 (TES 2006). That is, the audit examined the development and publication of the detailed statement of actual tax expenditures required by Division 2 of Part 5 of the CBH Act. The development and publication of aggregated information on projected tax expenditures included in the Budget Papers pursuant to Division 1 of Part 5 of the CBH Act was not examined.

The objective of the audit was to determine the effectiveness of DoHA's administration of the MoU between the Government and the pathology profession, including monitoring whether the MoU is achieving its objectives

The purpose of the report was to report to the Parliament on how effectively and efficiently the Australian Taxation Office administers the Tax File Number System, and to identify opportunities for improvement of that system. The ANAO developed a methodological framework for the evaluation of the efficiency and effectiveness of the ATO's administration of the TFN system. The framework examined the TFN system; individuals and their TFNs; TFN withholding tax arrangements; and TFN information matching.

The objectives for the audit were to assess the:

• economy, administrative effectiveness, and accountability of DVA's management of the purchase of hospital services from State and Territory governments; and
• strategies adopted by DVA to manage change associated with its purchase of hospital care services from State and Territory governments.

The twin aims were to provide assurance to stakeholders and to identify any area in which improvements could be made to achieve better results.

The objective of the audit was to determine whether the POI information recorded by Centrelink accords with relevant policy and thereby effectively supports informed decision-making regarding eligibility for the payment of various benefits to Centrelink customers

The ANAO's purpose was to report on:

• the HIC's management of approaches to minimise medifraud and inappropriate practice;
• HIC's reporting of its performance on these matters to stakeholders;
• the methodology used by the HIC to estimate the extent of fraud and inappropriate practice, including comment on the reliability of the estimates; and
• the HIC's implementation of the major recommendations from Medifraud and Excessive Servicing - Audit Report No.17 1992-93.

The audit examined the effectiveness and efficiency of the FAO's management of overpayments, within the FTB Programme. In particular, the ANAO considered the FAO's activities in relation to FTB debt prevention, identification, raising and recovery. The audit also compared the FAO's policy documentation and guidance material for staff, against relevant sections of Family Assistance legislation.

The objective of the audit was to examine how effectively Health manages the risk of PBS drugs not being used according to PBS subsidy conditions. The audit examined two areas: during listing, how Health identified and implemented measures to decrease the risks of PBS drugs being used outside subsidy conditions; and following listing, how Health confirmed that usage and expenditure on PBS drugs was consistent with estimates. The report examines selected approaches used by Health, which have evolved in recent years, to manage the risk of PBS drugs being used outside subsidy conditions. The report also acknowledges and describes the role of the expert committees. The scope of the audit was limited to PBS drugs for which Health pays a subsidy. The audit did not examine Health's role in educating consumers, prescribers, and other health professionals, or the implications of the Australia–United States Free Trade Agreement for the PBS. Additionally, the ANAO did not form an opinion on the success of Medicare Australia's compliance role. To form an opinion against the audit objective, the ANAO interviewed Health personnel, committee members and stakeholders, examined relevant documents and files, analysed drug usage and expenditure data, and attended a number of committee meetings. To assist the audit process, the ANAO selected a sample of eight drugs. The drugs were selected due to their high cost to the PBS and/or high usage, or because the drug has had a particularly interesting PBS history. The sample is not representative of all drugs on the PBS. In 2004–05, 15.3 million prescriptions were written for these eight drugs, with the Government subsidy totalling $1.05 billion.

The objective of this audit was to assess key aspects of the establishment and administration of HIP by DEWHA as well as the transition of the program to DCCEE. All phases of the program were examined with particular emphasis for Phase 2 being given to:

• payment of rebates; and
• the compliance strategy underpinning the program.
