The audit reviewed the Defence's $5.05 billion New Submarine Project which commenced in 1982 and involves design and construction of six Collins class submarines and associated supplies and services. The objectives of the audit were to assess project management by the Department's Project Office in the light of accepted better-practice project management techniques. It also aimed to derive lessons learnt and recommendations that could be applied to the Project and to similar Defence projects now and in the future. The audit follows a 1992 audit of the Project by the ANAO and a review by the Joint Committee of Public Accounts in 1995.

The objectives of this audit were to assess, with respect to guarantees, indemnities and letters of comfort:

• changes in the size and nature of the Commonwealth's reported exposure since 30 June 1995;
• the extent of improvement in agencies' management and monitoring of the Commonwealth's exposure to these instruments;
• the approach of agencies to effective risk management and control of Commonwealth exposures to these instruments; and
• whether current reporting practices provide a sufficiently comprehensive coverage for public accountability purposes, at both the agency and whole of government levels.

The ANAO could assess the Department of Industry, Science and Resources’ management of its decommissioning and rehabilitation activities. The department manages a range of complex decommissioning and rehabilitation activities, such as decommissioning the Northern Endeavour facility and overseeing the rehabilitation of the Ranger and the Rum Jungle former uranium mine sites.

The Audit reviewed the Commercial Support Program (CSP) within the Department of Defence. The CSP was introduced in 1991 following a review of the report, The Defence Force and the Community. Its objective is to achieve best value for money in the acquisition of support services for the Department of Defence and to give the private sector an opportunity to participate in the provision of those support services. The objective of this audit was to assess whether CSP was meeting its objectives and to identify any areas where it may be possible to improve the timeliness, and therefore cost-effectiveness, with which CSP is implemented and the quality of the process itself to produce better outcomes.

The audit was conducted in response to a November 2000 resolution of the Senate that the Auditor-General examine all expenditures and entitlements accruing to Parliamentarians in 1999-2000. The objectives of the audit were to:

• provide assurance to the Parliament regarding the administration by Finance, the chamber departments and the portfolio departments of all expenditures and entitlements accruing to Parliamentarians, including Ministers, in 1999-2000;
• assess the administrative and control structures governing expenditures and entitlements accruing to Parliamentarians and Ministers in 1999-2000; and
• identify opportunities to improve the current framework.

The objective of this audit is to assess whether the Director of National Parks (the Director) is effectively managing Commonwealth national parks in conjunction with relevant boards of management, including by implementing the recommendations from Auditor-General Report No.49 2018–19 Management of Commonwealth National Parks.

The ANAO could continue the ANAO’s series of audits on cyber security. The scope would include assessing selected entities’ cyber security frameworks and controls against the controls required under the Protective Security Policy Framework and the Australian Signals Directorate’s Essential Eight Maturity Model.

The audit reviewed the fraud control arrangements in the Department of Family and Community Services (FaCS), a policy formulation, and advising body and major purchaser of social welfare services from Centrelink. The objective was to assess whether FaCS had:

• implemented appropriate fraud control arrangements in line with the Fraud Control Policy of the Commonwealth and that these arrangements operated effectively in practice; and
• fulfilled its responsibilities as a purchaser of services in relation to fraud control.

This audit is one in a series of fraud control audit and is complemented by a similar audit of Centrelink, a major provider of services on behalf of FaCS.

The objective of this audit was to assess the administration of internal fraud control arrangements in the ATO and to identify areas with potential for improvement as well as identified better practice. To achieve this objective the ANAO focussed on five key areas. These were:

• the application of the ATO's corporate governance processes to the internal fraud control activities;
• the prevention of internal fraud within the ATO;
• the related use of information technology to minimise fraud risks;
• the detection of internal fraud within the ATO; and
• ATO fraud investigation procedures and practices.

The purpose of this follow-up audit was to report on action taken by the Department of Social Security and Centrelink in addressing the recommendations of Audit Report No.23 1993-94 Protection of Confidential Client Information from Unauthorised Disclosure. The objectives were to:

• ascertain the extent to which the recommendations of the original audit have been implemented;
• identify other changes made in relation to data confidentiality within the Social Security portfolio since 1993;
• assess the impact of the changes made; and
• identify any scope for further improvement.

This cross-portfolio audit reviewed the management of Internet security across ten Commonwealth agencies, with the objective of forming an opinion on the adequacy of Internet security management within the selected agencies. The audit pursued two strands - a review of the management systems employed within agencies including the adequacy of risk assessments, security policies and plans, day to day management and business continuity planning in connection with the agencies' Internet presence, and physical testing of the security arrangements of selected Internet sites. Staff from the Defence Signals Directorate were appointed under the Auditor-General Act 1997 to perform the site testing.

The ANAO could assess whether the Department of Defence (Defence) and the Department of Finance (Finance) are effectively managing the divestment of Defence estate holdings identified through the Defence Estate Audit. In response to the 2023 Defence Strategic Review, government commissioned an independent audit of the Defence estate to assess whether the estate footprint was fit for purpose. In February 2026, government announced that it had endorsed the whole or partial divestment of 67 Defence holdings. Finance is responsible for managing the new divestments while Defence is to manage the transition of people and capability from sites. The divestment program involves heritage, remediation, workforce, community and capability considerations. The ANAO could examine whether implementation arrangements support transparent, orderly and value for money disposal outcomes.

The ANAO could assess the National Disability Insurance Agency’s (NDIA) policies and practices for procuring goods and services — including planning, market engagement, risk management, probity arrangements, tender evaluation, contract management and transparency. As a non-prescribed corporate Commonwealth entity, the NDIA is not required to comply with the Commonwealth Procurement Rules. A March 2023 Independent Review of Services Australia and NDIA Procurement and Contracting identified deficiencies and deviations from good practice in relation to NDIA’s procurement practices, and made recommendations to improve documentation, probity, competition, reporting, and value-for-money assessments. In 2024–25, the NDIA reported 40 contracts with an original value of over $1 million, the combined value of which was over $484 million.

This audit followed up the ANAO's 2000 performance audit report on retention of military personnel (Audit Report No.35 1999-2000 Retention of Military Personnel), which focused on examining whether ADF personnel management practices to retain personnel were commensurate with the cost of recruiting and training new personnel, or whether more cost- effective steps could be taken to reduce the separation rates of desirable personnel. The objective of the follow-up audit was to assess Defence's implementation of recommendations made in the original audit report and their effectiveness in helping Defence control the flow of trained personnel from the Services.

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.

Defence has long provided housing assistance for members of the Australian Defence Force (ADF) and their families. In 1988, this function passed to the Defence Housing Authority (DHA), which was established to provide suitable housing to meet Defence's operational needs. In 2000, Defence and DHA signed a Services Agreement valued at $3.5 billion over 10 years. The objective of the audit was to assess whether Defence's management of its housing and relocation services provided for ADF members meets specified requirements; and to make practical recommendations for more efficient, effective and economical use of public resources provided for this purpose.

The ANAO could assess the design and early implementation of the measures in the ‘Expanding access to high quality early education’ 2025–26 Federal Budget package, with a focus on the $3.6 billion Worker Retention Payment, and $1 billion Building Early Education Fund.

The audit covered major program elements within the Department of Primary Industries and Energy and Environment Australia that are managed:

• directly by DPIE or Environment Australia;
• through the One-Stop-Shop project assessment process administered by the States/Territories; or
• by non-government organisations.

The purpose of the audit was to examine and benchmark the administrative processes established for these programs. The primary focus of the audit was to draw on the best elements of past practice (particularly in relation to programs involving the One-Stop-Shop) and highlight any shortcomings so that the risks to program effectiveness and accountability could be addressed in the implementation of the Natural Heritage Trust.

The ANAO assessed agencies' progress in implementing the seven recommendations of Audit Report No.47 of 1998-99, Energy Efficiency in Commonwealth Operations. The Objectives of the follow-up audit were to

(i) asses the extent to which selected Commonwealth agencies have implemented the recommendations of Report No. 47 of 1998-1999, taking account of any changed circumstances or new administrative issues identified as impacting upon implementation of these recommendations; and

(ii) offer continued assurance to the Parliament on the management of Commonwealth agencies' compliance with the Commonwealth energy efficiency requirements, and to identify areas of better practice in energy management by those agencies.

The audit focused on the sale of properties from that portion of the domestic property estate managed by the Department of Finance and Administration and identified for sale via a three year divestment strategy of the Commercial Office Estate by Government in April 1997. The audit sought to assess the effectiveness of the management of the sales process for selected property sales, including the extent to which the Government's sale objectives have been achieved; review the long-term sale and leaseback arrangements for selected divested properties and whether they adequately protect the Commonwealth's interests; and identify principles of sound administrative practice to facilitate improved administrative arrangements for future property sales.

The ANAO could assess Australian Competition and Consumer Commission’s regulation of supermarkets through the mandatory Food and Grocery Code of Conduct. The Food and Grocery Code of Conduct is a mandatory code to regulate the conduct of large grocery businesses towards their suppliers. The code has been in place since April 2025.

The ANAO could assess whether the design and implementation of National Disability Insurance Scheme (NDIS) reforms are delivering a consistent, person-centred experience and improving outcomes, with effective codesign, intergovernmental engagement and information sharing to support implementation. This could include reforms to the governance and stewardship of the scheme.

Since 2024, the Australian Government has introduced legislative changes and announced over $2 billion in funding to ‘get the NDIS back on track’ and build foundational disability supports outside of the NDIS. These reforms have been informed by recommendations of the 2023 Independent Review of the NDIS and enabled by the National Disability Insurance Scheme Amendment (Getting the NDIS Back on Track No. 1) Act 2024. The reforms aim to make planning fairer, more consistent and evidence based, while also improving coordination across jurisdictions.

On 22 April 2026 the Minister for the NDIS announced a further tranche of reforms to the NDIS. Delivering these changes relies on effective co-design with the disability community, and clear protocols for negotiation and information sharing with state and territory governments. Audit activity could assess aspects of the overall governance and coordination of the NDIS reforms or focus on the design and implementation of specific reform elements such as the new planning framework, support needs assessment tool, digital payment and provider enrolment system, early intervention pathway, navigator function, Thriving Kids initiative, and establishment of other foundational supports.

The Office of Supply Chain Resilience, located within the Department of Industry, Science and Resources, was established to strengthen the resilience of Australia’s critical supply chains. The ANAO could examine the effectiveness of the Office of Supply Chain Resilience in identifying, assessing, and coordinating actions to address supply-chain vulnerabilities affecting Australia’s economic and national resilience.

The review assessed the effectiveness of the ANAO’s methodology for conducting audits of other Australian Government entity’s performance statements. See the review.

This page lists status updates about the ANAO's progress on recommendations contained in the review.

This report summarises audit findings relating to entity internal control structures arising from the interim phase of the financial statement audits of major Commonwealth entities for 2001-2002. Examinations of such issues are designed to assess the reliance that can be placed on control structures to produce complete, accurate and valid information for financial reporting purposes.

The audit's objective was to assess, and report to Parliament on, the ATO's administration of petroleum excise collections. The audit examined whether the ATO had implemented effectively administrative arrangements for the collection of petroleum excise since the transfer of the function from Customs in 1999. Areas that were examined relating to administration of petroleum excise were:

• governance arrangements;
• licensing arrangements;
• compliance management;
• investigations; and
• revenue management.

The audit also reviewed the role of Customs in performing functions directly related to petroleum excise collections and key elements of the management relationship between the ATO and Customs in this area.

The audit reviewed the Defence Department's management of the Defence Cooperation (DC) Program, through which Australia interacts with and provides assistance to security forces in South East Asia and the South Pacific. The primary aim of the program is to support Australia's defence relationships. Activities conducted through the program include training, study visits, personnel exchanges and combined exercises with elements of the various regional armed forces. The Pacific Patrol Boat Project is part of the program. The objectives of the audit were to:

1) consider how Defence assesses performance in meeting DC objectives;

2) review Defence's development of DC objectives; and

3) identify areas for improvement in managing DC resources.

The audit reviewed the implementation of the Whole-of-Government Information Technology Infrastructure Consolidation and Outsourcing Initiative (IT Initiative). The objectives of the audit were to examine the administrative and financial effectiveness of the implementation of the IT Initiative, with the focus being on the first four tenders conducted. Accordingly, the audit assessed:

• the effectiveness of the overall planning and implementation of the IT Initiative, taking into account the tendering, contracting and monitoring processes undertaken in respect of Cluster 3, DEETYA/EN, ATO and Group 5;
• the extent to which those latter processes have contributed to the achievement of the objectives of the IT Initiative; and
• the extent to which the Commonwealth's interests have been adequately protected within this context.

The objective of the audit was to assess whether Centrelink's Balanced Scorecard (BSC) was based on key elements of better practice principles and its use assisted Centrelink to understand and communicate its performance against its strategic goals. The audit examined:

• the use of the BSC in setting Centrelink's vision and goals;
• the role of the BSC in planning;
• alignment of the BSC from the top down through the organisation and the interdependencies of scoreboards used by various support units, the definition and use of measures, including target setting and links to goals within the BSC framework; and
• its use in monitoring, reporting and feedback.

The Australian Government undertakes investments through a range of models, including private sector investments, to achieve policy and investment outcomes. The ANAO could assess the management of a selection of investments to ensure value for money, transparency and return on the investment is achieved. The audit would consider design, implementation, oversight, governance and reporting arrangements for the selected investments.
