Federal Executive Council (Australia) in the context of Minister for Foreign Affairs (Australia)

The governor-general of Australia is the federal representative of the monarch of Australia, currently Charles III. The governor-general has many constitutional and ceremonial roles in the Australian political system, in which they have independent agency. However, they are generally bound by convention to act on the advice of the prime minister and the Federal Executive Council. They also have a significant community role, through recognising meritorious individuals and groups, and representing the nation as a whole. The current governor-general is Sam Mostyn.

Significant functions of the governor-general include giving royal assent to bills passed by the houses of parliament, issuing writs for elections, exercising executive power on the advice of the Federal Executive Council, formally appointing government officials (including the prime minister, other ministers, judges and ambassadors), acting as commander-in-chief of the Australian Defence Force, and bestowing Australian honours. However, in almost all instances the governor-general only exercises de jure power in accordance with the principles of the Westminster system and responsible government. This requires them to remain politically neutral and to only act in accordance with Parliament (such as when selecting the prime minister and providing royal assent) or on the advice of ministers (when performing executive actions). However, in certain limited circumstances, the governor-general can exercise reserve powers (powers that may be exercised without or against formal advice), most notably during the 1975 Australian constitutional crisis. These situations are often controversial and the use of and continued existence of these powers remains highly debated.

The Treasurer of Australia, also known as the Federal Treasurer or more simply the Treasurer, is the minister of state of the Commonwealth of Australia charged with overseeing government revenue collection, federal expenditure and economic policy as the head of the Department of the Treasury. The current treasurer is Jim Chalmers, who was selected by Prime Minister Anthony Albanese in May 2022 following the 2022 Australian federal election.

The Treasurer implements ministerial powers through the Department of the Treasury and a range of other government agencies. According to constitutional convention, the Treasurer is always a member of the Parliament of Australia with a seat in the House of Representatives. The office is generally seen as equivalent to the Chancellor of the Exchequer in the United Kingdom or the Secretary of the Treasury in the United States or, in some other countries, the finance minister. It is one of only four ministerial positions (along with prime minister, Minister for Defence and Attorney-General) that have existed since Federation.

The minister for defence is the minister of state of the Commonwealth of Australia charged with overseeing the organisation, implementation, and formulation of strategic policy in defence and military matters as the head of the Department of Defence. The minister for defence is responsible for the Australian Defence Organisation, including the Australian Defence Force (ADF). The current defence minister is Richard Marles, who is also concurrently serving as deputy prime minister of Australia, having been selected by Prime Minister Anthony Albanese in May 2022 following the 2022 Australian federal election.

As the minister for defence is responsible for the management of Australia's defence and military forces and the portfolio's accountability to the Parliament, the secretary of defence is required under section 63(1) of the Public Service Act 1999 and the Requirements for Annual Reports from the Parliamentary Joint Committee on Public Accounts and Audit to submit a report to the responsible ministers on the activities of the Department of Defence after the end of each financial year for presentation to the Parliament.
