The audit is a follow-up of ANAO Audit Report No.33 of 1997-98, which assessed the effectiveness and efficiency of the Commonwealth's management of the Great Barrier Reef and made seven recommendations for improvement. The objective of the follow-up audit was to assess the extent to which the Great Barrier Reef Marine Park Authority, which is responsible for advising the Commonwealth on the care and developement of the Marine Park, has implemented the recommendations of the earlier audit.

The objective of the audit was to assess the effectiveness of the Department of the Environment’s regulation of proponents’ compliance with Part 9 of the Environment Protection and Biodiversity Conservation Act 1999.

The objectives in auditing the sale were to assess the extent to which the Government's sale objectives were achieved; review the efficiency of the management of the sale process; assess whether the sale arrangements adequately protected the Commonwealth's interests, including minimising ongoing Commonwealth risk; and identify principles of sound administrative practice to facilitate improved arrangements for future trade sales, particularly the later phases of airport sales.

The audit sought to assess the efficiency and effectiveness of the ADF's management of fuel and lubricants and to identify possible areas for improvement. The audit focused on major aspects of the fuel supply chain, in particular the strategic management of fuel (eg. the coordination of fuel requirements and stockholding policy). The audit also reviewed fuel procurement practices, storage and handling issues. The audit coverage addressed the fuel supply aspects of these matters rather than transport, distribution and equipment issues. Although directed principally towards operational fuels, the audit took into consideration issues associated with ADF's requirement for oils and lubricants.

The audit objective was to assess the effectiveness of the Department of Human Services’ management of the trials of intensive service delivery for customers with complex needs.

A Special Account is a mechanism used to record amounts in the Consolidated Revenue Fund that are set aside for specified purposes. A total of $3.40 billion was reported as held in Special Accounts as of 30 June 2003, with $10.33 billion reported as credited to Special Accounts in 2002-03 and $10.06 billion in reported payments (debits) from these Accounts. The audit examined the establishment, management and abolition of Special Accounts by Commonwealth agencies, as well as compliance with legal requirements

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.
