Politics of Australia

The politics of Australia operates under the written Australian Constitution, which sets out Australia as a constitutional monarchy, governed via a parliamentary democracy in the Westminster tradition. Australia is also a federation, where power is divided between the federal government and the states. The monarch, currently King Charles III, is the head of state and is represented locally by the governor-general, while the head of government is the prime minister, currently Anthony Albanese.

The country has maintained a stable liberal democratic political system under its Constitution, the world's tenth oldest, since Federation in 1901. Australia is the world's sixth oldest continuous democracy and largely operates as a two-party system in which voting is compulsory.{{cite web |url=http://regional.gov.au/territories/norfolk_island/administrator/media/2015/ni-a-mr-201506.aspx|title=Commonwealth Day 2015|last=Hardgrave|first=Gary|date=2 March 2015|publisher=Department of Infrastructure and Regional Development, Government of Australia|access-date=1 September 2015}}{{cite web |url=http://www.aec.gov.au/FAQs/Voting_Australia.htm#compulsory |title=Is voting compulsory? |work=Voting within Australia – Frequently Asked Questions |publisher=Australian Electoral Commission |date=2015 |access-date=1 September 2015}} {{Democracy Index rating|Australia|full democracy|2023}}

Like other Westminster-style systems of government, Australia's federal system of government consists of three branches: the legislative (Parliament), the executive (the prime minister, the cabinet, other ministers, and government departments), and the judicature (the High Court of Australia and other federal courts). The Australian government consists of the party or coalition that had majority support in the lower house and exercises both executive (as ministers) and legislative (through control of the House) power.

The federal Parliament (as defined in section 1 of the Constitution) comprises the monarch and is bicameral (has two chambers): the House of Representatives (lower house) and Senate (upper house).{{Cite web |title=Bicameral representation |url=https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/APF/monographs/What_lies_beneath/Bicameral |archive-url=https://web.archive.org/web/20230317044400/https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/APF/monographs/What_lies_beneath/Bicameral |archive-date=2023-03-17 |access-date=2023-06-03 |publisher=Parliament of Australia |language=en-AU}} The House of Representatives has 151 members, each representing an individual electoral district of about 165,000 people.{{Cite web |title=Members |url=https://www.aph.gov.au/Senators_and_Members/Members |archive-url=https://web.archive.org/web/20120220192532/http://www.aph.gov.au/Senators_and_Members/Members |archive-date=2012-02-20 |access-date=2023-06-03 |publisher=Parliament of Australia |language=en-AU}} The Senate has 76 members: twelve from each of the six states and two each from Australia's internal territories, the Australian Capital Territory and Northern Territory.

Separation of powers is the principle the power of state should be shared between multiple bodies, in order to avoid the concentration of power in one entity.{{Cite web |title=Separation of powers: Parliament, Executive and Judiciary |url=https://peo.gov.au/understand-our-parliament/how-parliament-works/system-of-government/separation-of-powers-parliament-executive-and-judiciary/ |url-status=live |archive-url=https://web.archive.org/web/20231031132705/https://peo.gov.au/understand-our-parliament/how-parliament-works/system-of-government/separation-of-powers-parliament-executive-and-judiciary/ |archive-date=31 October 2023 |access-date=2023-11-08 |website=Parliamentary Education Office |publisher= |language=en}} The legislature proposes and debates laws that the executive then administers, and the judicial arbitrates cases arising from the administration of laws and common law. However, in accordance with Westminster system, there is no strict separation between the executive and legislative branches, with ministers required to also be members of the legislature.{{Cite Legislation AU|Cth|act|coaca430|Australian Constitution|64}}{{Cite book |last1=Williams |first1=George |title=Blackshield and Williams Australian constitutional law and theory: commentary and materials |last2=Brennan |first2=Sean |last3=Lynch |first3=Andrew |date=2018 |publisher=The Federation Press |isbn=978-1-76002-151-1 |edition=7th |location=Sydney |page=25 |quote=Under the Westminster system of government which Australia has inherited from the United Kingdom ... there is no similar strict separation between legislative and executive power. On the contrary, the executive is integrated into the legislature by the requirement that the ministers responsible for the departments of government must be Members of Parliament accountable to it through such mechanisms as question time.}} Only the High Court can deem if a law is constitutional or not.

The Australian system of government combines elements derived from the political systems of the United Kingdom (fused executive, constitutional monarchy) and the United States (federalism, written constitution, strong bicameralism), along with distinctive local features, and has therefore been characterised as a "Washminster mutation".{{Cite web |title=How have the British and US systems of government influenced the Australian government system? |url=https://peo.gov.au/understand-our-parliament/your-questions-on-notice/ |access-date=2023-12-05 |website=Parliamentary Education Office |language=en}}{{cite journal |last=Thompson |first=Elaine |date=1980 |title=The "Washminster" Mutation |url=https://www.tandfonline.com/doi/abs/10.1080/00323268008401755 |journal=Australian Journal of Political Science |volume=15 |issue=2 |pages=32–40 |doi=10.1080/00323268008401755 |url-access=subscription |via=Taylor & Francis Online |doi-access=}}{{Cite journal |last=Thompson |first=Elaine |date=2001 |title=The Constitution and the Australian System of Limited Government, Responsible Government and Representative Democracy: Revisiting the Washminster Mutation |url=https://www.austlii.edu.au/cgi-bin/viewdoc/au/journals/UNSWLJ/2001/53.html |journal=University of New South Wales Law Journal |volume=24 |issue=3 |via=Austlii}}

Federal nature

Australia is a federation, with different powers and responsibilities for the three levels of government: the federal government, the states and territories and local government.

The federal nature and the structure of the Parliament of Australia were the subject of protracted negotiations among the colonies during the drafting of the Constitution.{{Cite web |title=Australasian Federation Convention |url=https://timeline.peo.gov.au/#event-australasianafederationaconvention |archive-url=https://archive.today/20230708202549/https://timeline.peo.gov.au/%23event-australasianafederationaconvention |archive-date=2023-07-08 |access-date=2023-07-08 |website=timeline.peo.gov.au |publisher=Parliamentary Education Office}} The House of Representatives is elected on a basis that reflects the differing populations of the states. Therefore, the most populous state, New South Wales, has 48 members, while the least populated, Tasmania, has only five.{{Cite web |last= |first= |title=Infosheet 8 – Elections for the House of Representatives |url=https://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/00_-_Infosheets/Infosheet_8_-_Elections_for_the_House_of_Representatives |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230626043015/https://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/00_-_Infosheets/Infosheet_8_-_Elections_for_the_House_of_Representatives |archive-date=26 June 2023 |access-date=2023-07-08 |website=Parliament of Australia |publisher=Parliament of Australia |language=en-AU}}{{cbignore|bot=medic}} This is in contrast to the Senate which is elected on a basis of equality among the states: all states elect 12 senators, regardless of population.

The federal government may only legislate on certain matters, with any remaining areas falling within the responsibility of the states. For example, the federal government has the responsibility for defence, inter-state trade and bankruptcy while the states have responsibility for healthcare and education. Additionally, the states can agree to refer any of their powers to the Commonwealth government via legislation, as has been done to allow the Commonwealth to regulate corporations.{{Cite Legislation AU|Cth|act|coaca430|Australian Constitution|51}}(xxxvii.) The federal government can also significantly influence state legislation by making tied grants (money which comes with certain conditions). This is a significant power due to high levels of vertical fiscal imbalance arising because of the limited revenue raising capabilities of the states.{{Cite web |last=Galligan |first=Brian |date=2014-09-15 |title=Renewing federalism: what are the solutions to Vertical Fiscal Imbalance? |url=http://theconversation.com/renewing-federalism-what-are-the-solutions-to-vertical-fiscal-imbalance-31422 |access-date=2023-12-11 |website=The Conversation |language=en-US}}

In addition, Australia has several territories, two of which are self-governing: the Australian Capital Territory and the Northern Territory. As these territories' legislatures exercise powers devolved to them by the Commonwealth, the Parliament of Australia has the authority to override their legislation and to alter their powers. Australian citizens in these territories are represented by members of both houses of the Parliament of Australia, albeit with less representation in the Senate. Norfolk Island was self-governing from 1979 until 2015, although it was never represented as such in the Parliament of Australia.{{Cite web |title=Three levels of government: governing Australia |url=https://peo.gov.au/understand-our-parliament/how-parliament-works/three-levels-of-government/three-levels-of-government-governing-australia/ |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230626070737/https://peo.gov.au/understand-our-parliament/how-parliament-works/three-levels-of-government/three-levels-of-government-governing-australia/ |archive-date=26 June 2023 |access-date=2023-07-08 |website=Parliamentary Education Office |publisher= |language=en}}{{cbignore|bot=medic}} The other inhabited territories: Jervis Bay, Christmas Island and the Cocos (Keeling) Islands, have never been self-governing.{{Cite web |title=Jervis Bay Territory governance and administration |url=https://www.infrastructure.gov.au/territories-regions-cities/territories/jervis-bay-territory/governance-administration |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230626095357/https://www.infrastructure.gov.au/territories-regions-cities/territories/jervis-bay-territory/governance-administration |archive-date=26 June 2023 |access-date=2023-07-08 |website=The Department of Infrastructure, Transport, Regional Development, Communications and the Arts |publisher=Government of Australia}}{{cbignore|bot=medic}}{{Cite web |title=Christmas Island governance and administration |url=https://www.infrastructure.gov.au/territories-regions-cities/territories/indian-ocean-territories/christmas-island/governance-administration |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230626095357/https://www.infrastructure.gov.au/territories-regions-cities/territories/indian-ocean-territories/christmas-island/governance-administration |archive-date=26 June 2023 |access-date=8 July 2023 |website=The Department of Infrastructure, Transport, Regional Development, Communications |publisher=Australian Government}}{{cbignore|bot=medic}}{{Cite web |title=Cocos (Keeling) Islands governance and administration |url=https://www.infrastructure.gov.au/territories-regions-cities/territories/indian-ocean-territories/cocos-keeling-islands/governance-administration |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230626095050/https://www.infrastructure.gov.au/territories-regions-cities/territories/indian-ocean-territories/cocos-keeling-islands/governance-administration |archive-date=26 June 2023 |access-date=8 July 2023 |website=The Department of Infrastructure, Transport, Regional Development, Communications and the Arts |publisher=Government of Australia}}{{cbignore|bot=medic}}

The third level of governance is local government, in the form of shires, towns or cities. The councils of these areas are composed of elected representatives (known as either councillor or alderman, depending on the state). Their powers are devolved to them by the state or territory in which they are located.

Constitution

The Australian Constitution sets down the powers and responsibilities of many of the institutions of the Australian Commonwealth. However, the prime minister, the cabinet and the other principles of responsible government are not explicitly mentioned in the document, along with most of the realities of exercise of executive power. This reflected the British influence on the document with its unwritten constitution.

The Parliament of Australia can propose changes to the Constitution. To become effective, the proposals must be put to a referendum of all Australians of voting age and must receive a double majority: a majority of all votes, and a majority of votes in a majority of states.{{Cite web |title=Referendums and plebiscites |url=https://peo.gov.au/understand-our-parliament/having-your-say/elections-and-voting/referendums-and-plebiscites/ |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230626071602/https://peo.gov.au/understand-our-parliament/having-your-say/elections-and-voting/referendums-and-plebiscites/ |archive-date=26 June 2023 |access-date=2023-07-08 |website= |publisher=Parliamentary Education Office |language=en}}{{cbignore|bot=medic}}

The Crown

File:Government_House_Canberra.JPG]]The monarch is the symbolic head of Australia and is ceremonially involved in all branches of the government, as a constitutive part of Parliament, formal holder of executive power and the person in whose name most criminal offences are brought. In a broader sense, the Crown represents the authority of the polity itself.{{Cite journal |last=Saunders |first=Cheryl |date=2015 |title=The Concept of the Crown |url=https://law.unimelb.edu.au/__data/assets/pdf_file/0004/1587019/383Saunders4.pdf |journal=Melbourne University Law Review |volume=38}} However, in all these functions they are represented by the governor-general, whose appointment is the only mandatory function of the monarch.

Since at least the passage and adoption of the Statute of Westminster, the Monarch of Australia (along with the monarchies of the other dominions) is a separate office from the Monarch of the United Kingdom, despite being held by the same person. As such, in Commonwealth matters, the monarch is only advised by Commonwealth ministers. By the Royal Style and Titles Act 1953, the Australian Parliament gave the Queen the title Queen of Australia, and in 1973 titles with any reference to her status as Queen of the United Kingdom and Defender of the Faith as well were removed.{{Cite web |title=Royal Style and Titles Act 1953 (Cth) |url=https://www.foundingdocs.gov.au/item-did-27.html |access-date=2023-08-05 |website=Documenting Democracy |publisher=Museum of Australian Democracy}}{{Cite web |title=Royal Style and Titles Act 1973 (Cth) |url=https://www.foundingdocs.gov.au/item-sdid-99.html |access-date=2023-08-05 |website=Documenting Democracy |publisher=Museum of Australian Democracy}}

Parliamentarians belong to either the government, the opposition or sit on the cross-bench (which includes independents and members of minor parties). The opposition consists of members of the second largest party or coalition in the House of Representatives. The Leader of the Opposition heads shadow cabinet, composed of shadow ministers who mirror, scrutinise and oppose government ministers and act as the government in waiting. Although the government, by virtue of commanding a majority of members in the lower house of the Parliament, can usually pass its legislation and control the workings of the House, the opposition can considerably delay the passage of legislation and obstruct government business if it chooses.{{Cite web |last= |first= |title=Infosheet 19 – The House, government and opposition |url=https://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/00_-_Infosheets/Infosheet_19_-_The_House_government_and_opposition |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20211220085704/https://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/Practice7/HTML/Chapter2/Government%20and%20Parliament |archive-date=20 December 2021 |access-date=2023-07-30 |website=Parliament of Australia |language=en-AU}}{{cbignore|bot=medic}} The day-to-day business of the House of Representatives is usually negotiated between the Leader of the House, appointed by the prime minister, and the Manager of Opposition Business in the House, appointed by the Leader of the Opposition.{{Cite web |last= |first= |title=The (official) Opposition |url=https://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/Practice7/HTML/Chapter2/The_(official)_Opposition |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230627030549/https://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/Practice7/HTML/Chapter2/The_(official)_Opposition |archive-date=27 June 2023 |access-date=2023-07-30 |website=Parliament of Australia |language=en-AU}}{{cbignore|bot=medic}}

The Executive Government

File:Government House Canberra.JPG, also known as "Yarralumla", is the official residence of the Governor-General.]]The executive's primary role is to implement the laws passed by the Parliament. Unlike the other two branches of government however, membership of the executive is not clearly defined. One definition describes the executive as a pyramid, consisting of three layers. At the top stands The King, as the symbolic apex and formal repository of executive power. Below him lies a second layer made up of the prime-minister, cabinet and other ministers who in practice lead the executive. Finally, the bottom layer includes public servants, police, government departments and independent statutory bodies who directly implement policy and laws.{{Cite web |title=Separation of powers: Parliament, Executive and Judiciary |url=https://peo.gov.au/understand-our-parliament/how-parliament-works/system-of-government/separation-of-powers-parliament-executive-and-judiciary/ |url-status=live |archive-url=https://web.archive.org/web/20231031132705/https://peo.gov.au/understand-our-parliament/how-parliament-works/system-of-government/separation-of-powers-parliament-executive-and-judiciary/ |archive-date=31 October 2023 |access-date=2023-11-08 |website=Parliamentary Education Office |publisher= |language=en}}{{Cite web |last=Appleby |first=Gabrielle |date=2023-09-14 |title=Explainer: what is executive government and what does it have to do with the Voice to Parliament? |url=https://newsroom.unsw.edu.au/news/business-law/explainer-what-executive-government-and-what-does-it-have-do-voice-parliament |access-date=2023-11-14 |website=UNSW Newsroom |publisher=University of New South Wales}}

Executive power is also difficult to clearly define. In the British context, it was defined by John Locke as all government power not legislative or judicial in nature.{{Cite book |last=Moore |first=Cameroon |title=Crown and Sword: Executive Power and the Use of Force by the Australian Defence Force |publisher=ANU Press |year=2017 |isbn=9781760461553 |location=Canberra |page=10 |doi=10.22459/CS.11.2017 |jstor=j.ctt1zgwk12.6 |doi-access=free}} The key distinction is that while legislative power involves setting down rules of general application, executive power involves applying those rules to specific situations. In practice however, this definition is difficult to apply as many actions by executive agencies are wide ranging, binding and conducted independently of Parliament. Ultimately whether a power is executive or legislative is determined on a case by case basis, and involves the weighing up of various factors, rather than the application of a strict test.{{Cite journal |last=Greentree |first=Catherine Dale |date=2020 |title=The Commonwealth Executive Power: Historical Constitutional Origins and the Future of the Prerogative |url=https://www.unswlawjournal.unsw.edu.au/wp-content/uploads/2020/09/06-GREENTREE.pdf |journal=University of New South Wales Law Journal |volume=43 |issue=3 |doi=10.53637/GJLF5868}}

The Federal Executive Council is a formal body which exists and meets to give legal effect to decisions made by the Cabinet, and to carry out various other functions.

The Constitution of Australia does not explicitly mention Cabinet; it existing solely by convention, with its decisions not in and of themselves having legal force. However, it serves as the practical expression of the Federal Executive Council, which is Australia's highest formal executive governmental body. In practice, the Federal Executive Council meets solely to endorse and give legal force to decisions already made by the Cabinet.{{Cite web |title=Why is it that the Prime Minister and Cabinet are not mentioned in the Australian Constitution? |url=https://peo.gov.au/understand-our-parliament/your-questions-on-notice/ |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230626070043/https://peo.gov.au/understand-our-parliament/your-questions-on-notice/questions/why-is-it-that-the-prime-minister-and-cabinet-are-not-mentioned-in-the-australian-constitution/ |archive-date=26 June 2023 |access-date=2023-08-05 |website=Parliamentary Education Office |language=en}}{{cbignore|bot=medic}} All members of the Cabinet are members of the Executive Council.

Until 1956 all members of the ministry were members of the Cabinet. The growth of the ministry in the 1940s and 1950s made this increasingly impractical, and in 1956 Robert Menzies created a two-tier ministry, with only senior ministers holding Cabinet rank, also known within parliament as the front bench. This practice has been continued by all governments except the Whitlam government.

When the non-Labor parties are in power, the prime minister makes all Cabinet and ministerial appointments at their own discretion, although in practice they consult with senior colleagues in making appointments. When the Liberal Party and its predecessors (the Nationalist Party and the United Australia Party) have been in coalition with the National Party or its predecessor the Country Party, the leader of the junior Coalition party has had the right to nominate their party's members of the Coalition ministry, and to be consulted by the Prime Minister on the allocation of their portfolios.

When Labor first held office under Chris Watson, Watson assumed the right to choose members of his Cabinet. In 1907, however, the party decided that future Labor Cabinets would be elected by the members of the parliamentary Labor Party, (the Caucus) and the prime minister would retain the right to allocate portfolios. This practice was followed until 2007. Between 1907 and 2007, Labor Prime Ministers exercised a predominant influence over who was elected to Labor ministries, although the leaders of the party factions also exercised considerable influence.{{Cite web |last= |first= |title=The Ministry |url=https://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/Practice7/HTML/Chapter2/The_Ministry |url-status=live |archive-url=http://webarchive.nla.gov.au/awa/20230428104209/http://www.aph.gov.au/About_Parliament/House_of_Representatives/Powers_practice_and_procedure/Practice7/HTML/Chapter2/The_Ministry |archive-date=28 April 2023 |access-date=2023-08-05 |website=aph.gov.au |language=en-AU}}{{cbignore|bot=medic}} Prior to the 2007 general election, the then Leader of the Opposition, Kevin Rudd, said that he and he alone would choose the ministry should he become prime minister.

The Judicature

As a federation, in Australia judicial power is exercised by both federal and state courts. However, unlike the UK's multiple legal systems there is only one legal system and like Canada and unlike the US there is only one common law of the nation, rather than a common law for each state.{{Cite AustLII|litigants=Lange v Australian Broadcasting Corporation|link=Lange v Australian Broadcasting Corporation|source=HCA|num=25|year=1997|parallelcite=(1997) 189 CLR 520, 563}}{{Cite journal |last=Zines |first=Leslie |date=2004 |title=The Common Law in Australia: Its Nature and Constitutional Significance |url=https://classic.austlii.edu.au/au/journals/FedLawRw/2004/16.html |journal=Federal Law Review |volume=32 |issue=3 |pages=337–355 |doi=10.22145/flr.32.3.1 |s2cid=211152623 |via=Austlii|hdl=1885/315561 |hdl-access=free }} Additionally, unlike Canada and the US, there is no distinct federal common law.{{Citation |last=Leeming |first=Mark |title=Common Law Within Three Federations |date=2007-11-08 |ssrn=1027508 |url=https://papers.ssrn.com/abstract=1027508 |type=SSRN Scholarly Paper |access-date=2023-12-11 |place=Rochester, NY |language=en |institution=University of Sydney}}

Federal judicial power is vested in the High Court of Australia and such other federal courts created by the Parliament, including the Federal Court of Australia, the Family Court of Australia, and the Federal Circuit Court of Australia. Additionally, the Parliament has the power to enact laws which vest federal authority in state courts.Robert French, '[http://www.hcourt.gov.au/assets/publications/speeches/current-justices/frenchcj/frenchcj15oct12.pdf Two Chapters about Judicial Power] {{Webarchive|url=https://web.archive.org/web/20190418023702/http://www.hcourt.gov.au/assets/publications/speeches/current-justices/frenchcj/frenchcj15oct12.pdf|date=18 April 2019}}', speech given at the Peter Nygh Memorial Lecture, 15 October 2012, Hobart, p 3. Since the Constitution requires a separation of powers at the federal level, only courts may exercise federal judicial power; and conversely, non-judicial functions cannot be vested in courts.{{Cite AustLII|litigants=R v Kirby; Ex parte Boilermakers' Society of Australia|link=R v Kirby; Ex parte Boilermakers' Society of Australia|source=HCA|num=10|year=1956|parallelcite=(1956) 94 CLR 254}}

State judicial power is exercised by each state's supreme court, and such other courts and tribunals created by the state parliaments.

The High Court of Australia is the supreme court in the Australian court hierarchy and the final court of appeal in Australia. It has both original and appellate jurisdiction, has the power of judicial review over laws passed by the Parliament of Australia and the parliaments of the states, and interprets the Constitution of Australia. The High Court is mandated by section 71 of the Constitution, which vests in it the judicial power of the Commonwealth of Australia. The High Court was constituted by the Judiciary Act 1903 (Cth). The High Court is composed of seven Justices: the Chief Justice of Australia, presently Stephen Gageler, and six other Justices.

The state supreme courts are also considered to be superior courts, those with unlimited jurisdiction to hear disputes and which are the pinnacle of the court hierarchy within their jurisdictions. They were created by means of the constitutions of their respective states or the self government Acts for the ACT and the Northern Territory. Appeals may be made from state supreme courts to the High Court of Australia.

Inferior courts are secondary to superior courts. Their existence stems from legislation and they only have the power to decide on matters which Parliament has granted them. Decisions in inferior courts can be appealed to the superior court in that area, and then to the High Court of Australia.

Until the passage of the Australia Act 1986, by the Australian and UK parliaments, some Australian cases could be referred to the British Judicial Committee of the Privy Council for final appeal. With this act, Australian law was made fully independent, and the High Court of Australia was confirmed as the highest court of appeal. The theoretical possibility of the British Parliament enacting laws to override the Australian Constitution was also removed.{{cite web |date=4 December 1985 |title=Australia Act 1986 |url=https://www.legislation.gov.au/Details/C2004A03181 |url-status=live |archive-url=https://webarchive.nla.gov.au/awa/20170223181529/https://www.legislation.gov.au/Details/C2004A03181 |archive-date=2017-02-23 |work=Federal Register of Legislation |publisher=Attorney-General's Department (Australia) |via=National Library of Australia}}{{cbignore|bot=medic}}

Elections

Federal elections are held at least once every three years.{{Efn|The timing of elections is related to the dissolution or expiry of the House of Representatives, which extends for a maximum period of three years from the date of its first sitting, not the date of the election of its members. The house can be dissolved and a new election called at any time. In 12 out of 41 parliaments since Federation, more than three years have elapsed between elections. There is a complex formula for determining the date of such elections, which must satisfy section 32 of the Constitution of Australia and sections 156–8 of the Commonwealth Electoral Act 1918. These provisions do not allow an election to be held less than 33 days or more than 68 days after the dissolution of the House of Representatives. See 2010 Australian federal election for an example of how the formula applies in practice.}} The prime minister can advise the governor-general to call an election for the House of Representatives at any time, but Senate elections can only be held within certain periods prescribed in the Australian Constitution. Although it is possible to hold elections for the House and Senate separately, it is the convention to hold simultaneous elections for both houses; every national election since 1974 has been for both the House and the Senate.

Voting has been compulsory federally since 1924, except for Indigenous Australians. All restrictions on Indigenous people's right to vote were removed in 1962, but this right remained optional until both voting and enrolment became compulsory in 1984.

All seats in the House of Representatives are contested in each election. Members are elected using preferential voting, in which the winning candidate obtains over 50% of votes after distribution of preferences; therefore, preference flows from lower-polling candidates are frequently significant in electoral outcomes. Senate elections are contested by half the senators from each state, except in the case of a double dissolution where all senators contest the election; senators representing the territories are elected and sworn into office simultaneously with the House of Representatives rather than the rest of the Senate. All senators are elected using the single transferable voting system of proportional representation, which has resulted in a greater presence of minor parties in the Senate. With the exception of a three-year period from 2005 to 2008, no party or coalition has held a majority in the Senate since 1981; this has required governments to frequently seek the support of minor parties or independent senators holding the balance of power in order to secure their legislative agenda.

Because the Senate's system of single transferable voting requires a lower quota than the House in order to obtain a seat, minor parties have often focused their election efforts on the upper house. This is true also at state level (only the two territories and Queensland are unicameral). Historically it has been comparatively rarer for minor parties and independents to win seats in the House of Representatives, although the size of the crossbench has been on an increasing trend since the 1990 federal election The most recent Australian federal election, which took place on 21 May 2022, saw the election of a historically large crossbench in the House of Representatives consisting of six minor party members and ten independents.

Australia's six states and the two largest territories are structured within a political framework similar to that of the Commonwealth. Each state has its own bicameral parliament, with the exception of Queensland and the two territories, whose parliaments are unicameral. Each state has a governor, who undertakes a role equivalent to that of the governor-general at the federal level, and a premier, who is the head of government and is equivalent to the prime minister. Each state also has its own supreme court, from which appeals can be made to the High Court of Australia.

State and territory elections occur every four years using fixed terms (except for Tasmania, where the premier decides the date of the election).{{Cite web |last=Muller |first=Damon |date=22 August 2022 |title=So when is the next federal election?

Labor winning government in New South Wales on 25 March 2023 marked the second time in history that the Australian Labor Party gained control of the entirety of Mainland Australia at the federal and mainland state levels simultaneously (leaving Tasmania as the only state with a Liberal government), a feat that had last been achieved in 2007.{{cite web | last=Slade | first=Lucy | title=Mainland Australia turns red after NSW Labor victory | website=9News | date=March 25, 2023 | url=https://www.9news.com.au/national/nsw-election-2023-mainland-australia-turn-red-as-labor-wins-nsw-election/50a42d1d-2374-479f-837d-c57bbdf28b71 | access-date=April 5, 2023}}{{cite web | last=Bongiorno | first=Frank | title=Australia is now almost entirely held by Labor – but that doesn't necessarily make life easier for leaders | website=The Conversation | date=March 27, 2023 | url=http://theconversation.com/australia-is-now-almost-entirely-held-by-labor-but-that-doesnt-necessarily-make-life-easier-for-leaders-202049 | access-date=April 5, 2023}} This would last until 24 August 2024 when Labor lost government in the Northern Territory to the Country Liberal Party (CLP) opposition.

Local government in Australia is the lowest tier of government. Local governments are subject to the relevant states and territories. There is only one level of local government in Australia; with none of the distinctive local government types seen in other anglophone nations. Most local governments within the states have equivalent powers to each other; styles such as shire or city have only historical meaning.

Political parties

{{Main|List of political parties in Australia|List of historical political parties in Australia}}

Organised, national political parties have dominated Australia's political landscape since federation. The late 19th century saw the rise of the Australian Labor Party, which represented organised workers.{{Cite web|url=https://www.nma.gov.au/defining-moments/resources/alp-forms|title=ALP forms|website=National Museum of Australia|access-date=23 January 2025}} Opposing interests coalesced into two main parties: a centre-right party with a base in business and the middle classes that has been predominantly conservative and moderate, now the Liberal Party of Australia;{{Cite web|url=https://www.nma.gov.au/defining-moments/resources/liberal-party-forms|title=Liberal party forms|website=National Museum of Australia|access-date=23 January 2025}} and a rural or agrarian conservative party, now the National Party of Australia.{{Cite web|url=https://www.nma.gov.au/defining-moments/resources/country-party|title=Country Party|website=National Museum of Australia|access-date=23 January 2025}}

Australian politics operates as a de facto two-party system, as a result of the permanent coalition between the Liberal Party and National Party.{{Cite web|url=https://peo.gov.au/understand-our-parliament/your-questions-on-notice/questions/define-the-two-party-system|title=Define the two-party system|access-date=23 January 2025|website=Parliamentary Education Office}} Internal party discipline has historically been tight, unlike the situation in other countries such as the United States.{{Cite web|url=https://www.aph.gov.au/About_Parliament/Senate/Practice_and_Procedure/platparl/c03|title=3. The electoral and party systems|website=Parliament of Australia|access-date=23 January 2025}} Australia's political system has not always been a two-party system. In the early years of Federation, the emerging Australian Parliament was a "substantial arena" of various fragmented political parties, and it was not until 1909, as parliamentary politics became increasingly bipolar, that the merger occurred and the party system coalesced into the Labor Party and a non-Labor bloc.

The Australian Labor Party (ALP) is a social democratic party. It is a left leaning party with tendency towards social welfare and government assistance programs. It was founded by the Australian labour movement and broadly represents the urban working and middle classes.

The Liberal Party of Australia is a party of the centre-right which broadly represents businesses, the middle classes and many rural people. Its permanent coalition partner at national level is the National Party of Australia, formerly known as the Country Party, a conservative party which represents rural interests. These two parties are collectively known as the Coalition. In only Queensland, the two parties have officially merged to form the Liberal National Party, and in the Northern Territory, the Country Liberal Party has associate status with both the Liberals and the Nationals.

=Minor/Third parties=

While there are a small number of other minor political parties that have achieved parliamentary representation, the Labor Party and the Coalition dominate organised politics throughout Australia. Historically, they have positioned themselves as opponents or ‘watchdogs’ of the major parties,{{Cite web|last=Ghazarian|first=Zareh|url=https://www.aph.gov.au/~/media/359C0D9F778D4F9D8572BA84276BB1D6.ashx|title=Small Parties, Big Changes: The Evolution of Minor Parties Elected to the Australian Senate|format=PDF|website=Parliament of Australia|page=1}} although since the 1980s, their political representation has been increasing: in the 1980 federal election, the combined primary votes of minor parties and independents accounted for only 8 %; by 2022, this figure had risen to 32 %, the highest ever recorded.{{Cite web|last1=Browne|first1=Bill|last2=Le|first2=Minh Ngoc|url=https://australiainstitute.org.au/post/the-steady-decline-of-voters-choosing-the-major-parties-is-reshaping-australia-politics/|title=The steady decline of voters choosing the major parties is reshaping Australian politics|website=The Australia Institute|date=24 October 2024|access-date=23 January 2025}}

Minor parties in Australian politics include a green party, the Australian Greens (the largest of the minor parties since 2004); a centrist party, Centre Alliance; a nationalist party, Pauline Hanson's One Nation; and a right-wing agrarian party, Katter's Australian Party. Other significant parties in recent years have included the Clive Palmer led United Australia Party (not to be confused with the historical incarnation that was the predecessor to the Liberal party) and the socially conservative Family First Party, among others. Historically significant parties have included the United Australia Party, the Democratic Labor Party (1950s–1970s), the Communist Party of Australia, the socially liberal Australian Democrats (1970s–1990s) among others.

A notable election result for a third party other than Labor or the Liberal, Nationals, was in the 1998 Queensland state election. Where One Nation with nearly 23% of the vote, gained the highest percentage of the vote than any other third party (i.e. not Labor, Coalition, or independents) at the state or territory level since Federation 1901. This was also the only election at which a third party gained more votes than both the Liberal Party and the National Party considered separately. This was One Nation's highest ever recorded election result in its history.

At the 2010 Tasmanian state election, the Greens secured 21.6% of the primary vote. This is the highest vote the Greens has ever recorded in any state or federal election as of 2024.

A collection of climate conscious and economically liberal independents commonly referred to as the teals were elected in the 2022 election, taking many seats previously held by moderate Liberal Party members.{{Cite news |last=Wahlquist |first=Calla |date=2022-05-23 |title=Teal independents: who are they and how did they upend Australia's election? |language=en-GB |work=The Guardian |url=https://www.theguardian.com/australia-news/2022/may/23/teal-independents-who-are-they-how-did-they-upend-australia-election |access-date=2023-12-12 |issn=0261-3077}}{{Cite web |last=Kenny |first=Mark |author-link=Mark Kenny (journalist) |date=2023-11-12 |title=Halfway through their term, the 'teal' MPs look here to stay – and may present a huge challenge in 2025 |url=http://theconversation.com/halfway-through-their-term-the-teal-mps-look-here-to-stay-and-may-present-a-huge-challenge-in-2025-216528 |access-date=2023-12-01 |website=The Conversation |language=en-US}}

Timeline

Since federation, there have been 31 prime ministers of Australia. The longest-serving prime minister was Sir Robert Menzies of the Liberal Party, who served for 19 years from 1939 to 1941, and again from 1949 to 1966. The only other prime minister to serve for longer than a decade was John Howard, also of the Liberal Party, who led for more than 11 years from 1996 to 2007. The Coalition and its direct predecessors have governed at the federal level for a large majority of Australia's history since federation: 30,791 days as compared to Labor's {{formatnum:{{#expr:
