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.
