The audit examined key aspects of the first four tenders for the RtB program. These tenders provided coverage across the Basin and resulted in expenditure in excess of $1 billion. The 2008–09 tenders included the largest single purchase under the program—$303 million to Twynam Agricultural Group. The audit also examined the Commonwealth's contribution to the purchase of Toorale station, the only purchase outside a tender process.

On 3 February 2010, Senator Christine Milne wrote to the Auditor General raising concerns about DEWHA's administration of the Green Loans program and requesting a performance audit of the program. Issues raised included: uncapped assessor numbers; problems with the delivery of the program; the quality of assessor training and assessments provided to households; the lack of an audit facility within the program; and equitable access to work under the program.

In light of Senator Milne's request and other concerns in relation to the administration of the program, the Auditor-General agreed on 25 February 2010 to conduct a performance audit of the program. The objective of the audit was to examine key aspects of the establishment and administration of the Green Loans program by DEWHA and the program's transition to DCCEE. Particular emphasis was given to the program's three main elements:

• training, registration and contracting of assessors;
• scheduling, conduct, and reporting of home sustainability assessments, and the associated payments to assessors; and
• provision of green loans to householders, and the associated payments to participating financial institutions.

The audit also examined the extent to which steps had been taken by DEWHA and DCCEE to assess whether the Green Loans program was achieving its objectives.

The objective of this audit was to assess the coordination of Australian, State and Territory Government climate change programs and the integrity of measuring and reporting of Australia's greenhouse gas emissions and abatement. Particular emphasis was given to the:

• coordination of Australian Government and State/Territory climate change programs;
• integrity of the national inventory to measure Australia's greenhouse gas emissions; and
• integrity of measuring and reporting government abatement measures.

The objective of the audit was to assess the effectiveness of Customs and Border Protection's performance in managing and coordinating enforcement operations against illegal foreign fishing in Australia's northern waters. The audit focused on Customs and Border Protection's role within the whole of government policy coordination framework; the effectiveness of its intelligence support for operational planning and policy and strategy development; its performance in planning, prioritising and administering effective enforcement operations; and its performance in measuring and reporting on the effectiveness of the program.
