Monarchy of Australia in the context of "Politics of Australia"

The Constitution of Australia (also known as the Commonwealth Constitution) is the fundamental law that governs the political structure of Australia. It is a written constitution, which establishes the country as a federation under a constitutional monarchy governed with a parliamentary system. Its eight chapters set down the structure and powers of the three constituent parts of the federal level of government: the Parliament, the Executive Government and the Judicature.

The Constitution was drafted between 1891 and 1898 at a series of conventions conducted by representatives of the six self-governing British colonies in Australia: New South Wales, Victoria, Queensland, Western Australia, South Australia and Tasmania. This final draft was then approved by each state in a series of referendums from 1898 to 1900. The agreed constitution was transmitted to London where, after some minor modifications, it was enacted as section 9 of the Commonwealth of Australia Constitution Act 1900, an act of the Parliament of the United Kingdom. It came into effect on 1 January 1901, at which point the six colonies became states within the new Commonwealth of Australia.

The Australian Government, also known as the Commonwealth Government or simply as the federal government, is the national executive government of Australia, a federal parliamentary constitutional monarchy. The executive consists of the prime minister, cabinet ministers and other ministers that currently have the support of a majority of the members of the House of Representatives (the lower house) and also includes the departments and other executive bodies that ministers oversee. The current executive government consists of Anthony Albanese and other ministers of the Australian Labor Party (ALP), in office since the 2022 federal election.

The prime minister is the head of the federal government and is a role which exists by constitutional convention, rather than by law. They are appointed to the role by the governor-general (the federal representative of the monarch of Australia). The governor-general normally appoints the parliamentary leader who commands the confidence of a majority of the members of the House of Representatives. Also by convention, the prime minister is a member of the lower house.

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 Order of Australia is an Australian honour that recognises Australian citizens and other persons for outstanding achievement and service. It was established on 14 February 1975 by Elizabeth II, Queen of Australia, on the advice of then prime minister Gough Whitlam. Before the establishment of the order, Australians could receive British honours, which continued to be issued in parallel until 1992.

Appointments to the order are made by the governor-general, "with the approval of The Sovereign", according to recommendations made by the Council for the Order of Australia. Members of the government are not involved in the recommendation of appointments, other than for military and honorary awards.

The Parliament of South Australia is the bicameral legislature of the Australian state of South Australia. It consists of the 47-seat House of Assembly (lower house) and the 22-seat Legislative Council (upper house). General elections are held every 4 years, with all of the lower house and half of the upper house filled at each election. It follows a Westminster system of parliamentary government with the executive branch required to both sit in parliament and hold the confidence of the House of Assembly. The parliament is based at Parliament House on North Terrace in the state capital of Adelaide.

Unlike the federal parliament and the parliaments of most other states, the South Australian Constitution does not define the parliament as including either the monarch or the governor of South Australia as one of its constituent parts. However, the constitution also vests legislative power in the state's governor acting with the advice and consent of both houses of parliament, making the role of the governor effectively the same as those of the other states.
