This annual report documents the performance of the Australian National Audit Office (ANAO) in the financial year ended on 30 June 2019. The report addresses all applicable obligations under the Public Governance, Performance and Accountability Act 2013; the Public Governance, Performance and Accountability Rule 2014; the Auditor-General Act 1997; the performance measures set out in the outcome and programs framework in the ANAO’s Portfolio Budget Statements 2018–19 and the ANAO Corporate Plan 2018–19, and annual reporting requirements set out in other relevant legislation.

The objective of the audit was to assess the administrative effectiveness of the ATO's management of GST compliance in the large business market segment. In conducting the audit the ANAO examined three key areas: governance - ILEC's corporate planning and reporting arrangements relevant to the management of GST compliance in the large business market segment; assessing and identifying compliance risks- how ILEC collects information relating to the large business market segment and how it uses this information to support risk identification and assessment; and managing compliance- compliance planning and the products and processes used by ILEC to manage GST compliance in the large business market segment and evaluating compliance outcomes to support future compliance planning and the targeting of GST compliance risks. In undertaking the audit, the ANAO took account of the findings of previous reviews, in particular the LCCP Review.

The audit objective was to assess the effectiveness of the administration of Aboriginal and Torres Strait Islander participation targets in intergovernmental funding agreements in achieving policy objectives.

Taxation rulings are a key mechanism used by the Australian Taxation Office (ATO) to disseminate the Commissioner of Taxation's interpretative advice on Australian taxation law. The objective of the audit was to:

report to Parliament on the operation of the ATO's administration of taxation rulings (public, private and oral rulings); and where appropriate, make recommendations for improvements, having regard to considerations of: efficiency and effectiveness of the ATO's administration of the rulings system, particularly in relation to the achievement of the objectives set by Parliament for the rulings system; the ATO's systems' capacity to deliver consistency and fairness for taxpayers; and good corporate governance, including the control framework.

The objectives of this follow-up audit were to:

• examine the ATO's implementation of the ten recommendations in The Australian Taxation Office's Management of its Relationship with Tax Practitioners (Audit Report No.19, 2002–03), having regard to any changed circumstances, or new administrative issues, affecting implementation of those recommendations; and
• identify scope for improvement in the ATO's management of its relationship with tax practitioners.

Follow up audits are recognised as an important element of the accountability processes of Commonwealth administration. Parliament looks to the Auditor General to report, from time to time, on the extent to which Commonwealth agencies have implemented recommendations of previous audit reports. Follow up audits keep Parliament informed of progressive improvements and current challenges in areas of Commonwealth administration that have previously been subject to scrutiny through performance audits.

The objective of the audit was to assess the effectiveness of DSEWPaC's administration of PIIOP, including the acquisition of water access entitlements and progress towards achieving the program's objectives.

Consistent with the ANAO's practices, and in response to a request from AusAID, a follow-up audit was conducted in the period May to November 1998 to assess the extent of implementation of the recommendations of a 1996 audit into the Management of Funding to Non-Government Organisations (NGOs)and whether the implementation of recommendations has effectively improved the management of funding to NGOs. The ANAO examined AusAID's key funding accountability documentation, tested the revised accountability arrangements and consulted a number of key stakeholders, including NGO representatives.

The audit theme was financial management and accountability. The audit concluded that six of the eight organisations had satisfactory payment of accounts processes and that GST administration control frameworks had been implemented. Payment of accounts processes could be improved by greater use of information technology whereas using risk management; formalising the BAS preparation procedures; and increasing monitoring and review procedures could improve GST administration.
