The Parliament of the Commonwealth of Australia, variously referred to as the Australian Parliament, the Commonwealth Parliament or the Federal Parliament, is the legislative branch of the government of Australia. It consists of three elements: the Queen of Australia, the Senate and the House of Representatives. The Queen is represented by the Governor-General. The combination of two elected houses, in which the members of the Senate represent the six States and the two self-governing Territories while the members of the House represent electoral divisions according to population, is modelled on the United States Congress. Through both houses, however, there is a fused executive, drawn from the Westminster System.
The lower house, the House of Representatives, currently consists of 150 members, each elected from single member constituencies, known as electoral divisions (commonly referred to as "electorates" or "seats") using compulsory preferential voting. This tends to lead to the chamber being dominated by two major parties, the Liberal/National Coalition and the Labor Party. The government of the day must achieve the confidence of this House in order to gain and remain in power.
The upper house, the Senate, consists of 76 members: twelve for each state, and two each for the Northern Territory and the Australian Capital Territory. Senators are elected using the Single Transferable Vote proportional representation system and as a result, the chamber features a multitude of parties vying for power. The governing party or coalition rarely has a majority in the Senate and usually needs to negotiate with other parties and Independents to get legislation passed.
Although elections can be called early, each 3 years the full House of Representatives and half of the Senate is dissolved and goes up for reelection. A deadlock breaking mechanism known as a Double Dissolution can be used to dissolve the full Senate as well as the House in the event that the Upper House refuses to pass a piece of legislation twice.

The current Parliament is the 45th Australian Parliament. The most recent federal election was held on 2 July 2016 and the 45th Parliament first sat on 30 August.
The outcome of the 2016 election saw the first-term incumbent Liberal/National Coalition re-elected with 76 seats in the 150-seat House of Representatives, a bare one-seat majority government − the closest federal majority result since the 1961 election. The Coalition lost 14 seats. The Shorten Labor opposition won 69 seats, an increase of 14 seats. On the crossbench the Australian Greens, the Nick Xenophon Team, Katter's Australian Party, and independents Andrew Wilkie and Cathy McGowan won a seat each.
The Senate result saw the Liberal/National Coalition with 30 seats (−3), Labor with 26 (+1), the Greens with 9 (−1), One Nation with 4 (+4) and Nick Xenophon Team with 3 (+2). Derryn Hinch won a seat, while Liberal Democrat David Leyonhjelm, Family First's Bob Day, and Jacqui Lambie retained their seats. The number of crossbenchers increased by two to a record 20. The Liberal/National Coalition required at least nine additional votes to reach a Senate majority, an increase of three. The Liberal/National Coalition and Labor parties agreed that the first elected six of twelve Senators in each state would serve a six-year term, while the last six elected in each state would serve a three-year term, despite two previous bipartisan senate resolutions to use an alternative method to allocate long and short term seats. By doing this, Labor and the Coalition each gained one Senate seat from 2019.
Bob Day, of the Family First Party resigned from the Senate on 1 November 2016 following the collapse of his business. The eligibility of him to run for the 2016 election is a matter that will be decided by the Court of Disputed Returns before any replacement can be appointed. 
Rodney Culleton, who had left Pauline Hanson's One Nation on 19 December 2016 to become an independent, also had his eligibility to run in the 2016 election questioned based on a larceny conviction. On 3 February 2017, the High Court decided that, since Culleton's liability to a two-year sentence for larceny had been in place at the time of the 2016 election, he had been ineligible for election and that this was not affected by the subsequent annulment of that conviction; the Court also held that the resulting vacancy should be filled by a recount of the ballot, in a manner to be determined by a single Justice of the Court.
He had also been declared bankrupt by the Federal Court on 23 December. Under the Constitution, a bankrupt person is disqualified from sitting in the federal parliament, so on the 11 January 2017, after being officially informed of the bankruptcy finding, the President of the Senate declared Culleton's seat vacant. A later appeal against the bankruptcy ruling was dismissed.
The Commonwealth of Australia came into being on 1 January 1901 with the federation of the six Australian colonies. The inaugural election took place on 29 and 30 March and the first Australian Parliament was opened on 9 May 1901 in Melbourne by Prince George, Duke of Cornwall and York, later King George V. The only building in Melbourne that was large enough to accommodate the 14,000 guests was the western annexe of the Royal Exhibition Building. After the official opening, from 1901 to 1927, the Parliament met in Parliament House, Melbourne, which it borrowed from the Parliament of Victoria (which sat, instead, in the Royal Exhibition Building until 1927). (The western annexe was demolished in the 1960s.)
It had always been intended that the national Parliament would sit in a new national capital.
On 9 May 1927, Parliament was moved to the new national capital of Canberra, where it met in what is now called Old Parliament House. This building was to house the Parliament for more than 60 years. A new Parliament House was opened on 9 May 1988 by Queen Elizabeth II.
Composition and electoral systems
The Constitution establishes the Commonwealth Parliament as being made of three components, the Queen of Australia, The Senate and the House of Representatives.
Most of the constitutional functions of the Crown are given to the Governor-General, whom the Monarch appoints on the advice of the Prime Minister to act as their representative in Australia. Specifically, the Constitution gives the Governor-General the power to assent to legislation, refuse to assent, or to reserve a bill for the Queen's pleasure. However, by convention, the Governor-General does not exercise these powers, other than in accordance with the advice of the Prime Minister.
The upper house of the Australian Parliament is the Senate, which consists of 76 members. Like the United States Senate, on which it was partly modelled, the Australian Senate includes an equal number of Senators from each state, regardless of population. Unlike it, however, the Australian Senate has always been directly elected. (The US Senate has been directly elected only from 1913.)
The Constitution allows Parliament to determine the number of Senators by legislation, provided that the six original states are equally represented. Furthermore, the Constitution provides that each original state is entitled to at least six Senators. However, neither of these provisions applies to any newly admitted states, or to territories. Pursuant to an Act of Parliament passed in 1973, Senators are elected to represent the territories. Currently, the two Northern Territory Senators represent the residents of the Northern Territory as well as the Australian external territories of Christmas Island and the Cocos (Keeling) Islands. The two Australian Capital Territory Senators represent the Australian Capital Territory, the Jervis Bay Territory and since 1 July 2016, Norfolk Island. While only half of the State Senate seats go up for re-election each three years as they serve six year terms, all of the Territory Senators must face the voters every three years.
Until 1949, each state elected the constitutional minimum of six Senators. This number increased to ten from the 1949 election, and was increased again to twelve from the 1984 election. The system for electing senators has changed several times since Federation. The original arrangement involved a first-past-the-post block voting or "winner takes all" system, on a state-by-state basis. This was replaced in 1919 by preferential block voting. Block voting tended to produce landslide majorities and even "wipe-outs". For instance, from 1920 to 1923 the Nationalist Party of Australia had 35 of the 36 senators, and from 1947 to 1950, the Australian Labor Party had 33 of the 36 senators.
In 1948, single transferable vote proportional representation on a state-by-state basis became the method for electing Senators. This change has led to the rise of a number of minor parties such as the Democratic Labor Party, Australian Democrats and Australian Greens who have taken advantage of this system to achieve parliamentary representation and the balance of power. From the 1984 election, group ticket voting was introduced in order to reduce a high rate of informal voting but in 2016, group tickets were abolished to avoid undue influence of preference deals amongst parties that were seen as distorting election results and a form of optional preferential voting was introduced.
Section 15 of the Constitution provides that a casual vacancy of a State senator shall be filled by the State Parliament. If the previous senator was a member of a particular political party the replacement must come from the same party, but the State Parliament may choose not to fill the vacancy, in which case Section 11 requires the Senate to proceed regardless. If the State Parliament happens to be in recess when the vacancy occurs, the Constitution provides that the State Governor can appoint someone to fill the place until fourteen days after the State Parliament resumes sitting.
House of Representatives
The House of Representatives is made up of single member electorates with roughly the same population. As is convention in the Westminster System, the party or coalition of parties that has the majority in this House forms the Government with the leader of that party of coalition becoming the Prime Minister. If the government loses the confidence of the House, they are expected to call a new election or resign.
Parliament may determine the number of members of the House of Representatives but the Constitution provides that this number must be "as nearly as practicable, twice the number of Senators"; this requirement is commonly called the "nexus provision". Hence, the House presently consists of 150 members. Each state is allocated seats based on its population; however, each original state, regardless of size, is guaranteed at least five seats. The Constitution does not guarantee representation for the territories. Parliament granted a seat to the Northern Territory in 1922, and to the Australian Capital Territory in 1948; these territorial representatives, however, had only limited voting rights until 1968.
From 1901 to 1949, the House consisted of either 74 or 75 members (the Senate had 36). Between 1949 and 1984, it had between 121 and 127 members (the Senate had 60 until 1975, when it increased to 64). In 1977, the High Court ordered that the size of the House be reduced from 127 to 124 members to comply with the nexus provision. In 1984, both the Senate and the House were enlarged; since then the House has had between 148 and 150 members (the Senate has 76).
From the beginning of Federation until 1918, first-past-the-post voting was used in order to elect members of the House of Representatives but since the 1918 Swan by-election which Labor unexpectedly won with the largest primary vote due to vote splitting amongst the conservative parties, the Nationalist Party of Australia government, a predecessor of the modern-day Liberal Party of Australia, changed the lower house voting system to full preferential voting as of the subsequent 1919 election which has remained in place since, allowing the Coalition parties to safely contest the same seats. Full-preference preferential voting re-elected the Bob Hawke government at the 1990 election, the first time in federal history that Labor had obtained a net benefit from preferential voting.
It is not possible to be simultaneously a member of both the Senate and the House of Representatives, but a number of people have been members of both houses at different times in their parliamentary career (see List of people who have served in both Houses of the Australian Parliament).
Only Australian citizens are eligible for election to either house. They must not also hold citizenship of a "foreign power". When the Constitution was drafted, all Australians were British subjects, so that "foreign" meant non-British. But, in the landmark case Sue v Hill (1999), the High Court of Australia ruled that, at least since the Australia Act 1986, Britain has been a "foreign power", so that British citizens are also excluded.
Compulsory voting was introduced for federal elections in 1924. The immediate justification for compulsory voting was the low voter turnout (59.38%) at the 1922 federal election, down from 71.59% at the 1919 federal election. Compulsory voting was not on the platform of either the Stanley Bruce-led Nationalist/Country party coalition government or the Matthew Charlton-led Labor opposition. The actual initiative for change was made by Herbert Payne, a backbench Tasmanian Nationalist senator who on 16 July 1924 introduced a private member's bill in the Senate. Payne's bill was passed with little debate (the House of Representatives agreeing to it in less than an hour), and in neither house was a division required, hence no votes were recorded against the bill. The 1925 federal election was the first to be conducted under compulsory voting, which saw the turnout figure rise to 91.4%. The turnout increased to about 95% within a couple of elections and has stayed at about that level since.
Australian Federal Police officers armed with assault rifles have been situated in both chambers of the Federal Parliament since 2015. It is the first time in Australian history that a parliament has possessed armed personnel.
Each of the two Houses elects a presiding officer. The presiding officer of the Senate is called the President; that of the House of Representatives is the Speaker. Elections for these positions are by secret ballot. Both offices are conventionally filled by members of the governing party, but the presiding officers are expected to oversee debate and enforce the rules in an impartial manner.
The Constitution authorises Parliament to set the quorum for each chamber. The quorum of the Senate is one-quarter of the total membership (nineteen); that of the House of Representatives is one-fifth of the total membership (thirty). In theory, if a quorum is not present, then a House may not continue to meet. In practice, members usually agree not to notice that a quorum is not present, so that debates on routine bills can continue without other members having to be present. Sometimes the Opposition will "call a quorum" as a tactic to annoy the Government or delay proceedings, particularly when the Opposition feels it has been unfairly treated in the House. The session of the relevant house is suspended until a quorum is present. It is the responsibility of the Government whips to ensure that, when a quorum is called, enough Government members are present to make up a quorum.
Both Houses may determine motions by voice vote: the presiding officer puts the question, and, after listening to shouts of "Aye" and "No" from the members, announces the result. The announcement of the presiding officer settles the question, unless at least two members demand a "division", or a recorded vote. In that case the bells are rung throughout Parliament House summoning Senators or Members to the chamber. During a division, members who favour the motion move to the right side of the chamber, whereas those opposed move to the left. They are then counted by the "tellers" (Government and Opposition whips), and the motion is passed or defeated accordingly. In the Senate, in order not to deprive a state of a vote in what is supposed to be a states' house, the President is permitted a vote along with other Senators (however, that right is rarely exercised); in the case of a tie, the President does not have a casting vote and the motion fails. In the House of Representatives, the Speaker does not vote, except in the case of a tie (see casting vote).
In the event of conflict between the two Houses over the final form of legislation, the Constitution provides for a simultaneous dissolution of both Houses – known as a double dissolution. If the conflict continues after such an election, the Governor-General may convene a joint sitting of both Houses to consider the disputed legislation. This has occurred on only one occasion, after the election following the 1974 double dissolution. However, there are other occasions when the two houses meet as one: see Joint meetings of the Australian Parliament.
The principal function of the Parliament is to pass laws, or legislation. Any Senator or Member may introduce a proposed law (a bill), except for a money bill (a bill proposing an expenditure or levying a tax), which must be introduced in the House of Representatives. In practice, the great majority of bills are introduced by ministers. Bills introduced by other Members are called private members' bills. All bills must be passed by both Houses to become law. The Senate has the same legislative powers as the House, except that it may not amend money bills, only pass or reject them. The enacting formula for Acts of Parliament is simply "The Parliament of Australia enacts:".
The Commonwealth legislative power is limited to that granted in the Constitution. Powers not specified are considered "residual powers", and remain the domain of the states. Section 51 grants the Commonwealth power over areas such as taxation, external affairs, defense and marriage. Section 51 also allows State parliaments to refer matters to the Commonwealth to legislate.
Section 96 of the Australian Constitution gives the Commonwealth Parliament the power to grant money to any State, "on such terms and conditions as the Parliament thinks fit." In effect, the Commonwealth can make grants subject to States implementing particular policies in their fields of legislative responsibility. Such grants, known as tied grants (since they are tied to a particular purpose), have been used to give the federal parliament influence over state policy matters such as public hospitals and schools.
The Parliament performs other functions besides legislation. It can discuss urgency motions or matters of public importance: these provide a forum for debates on public policy matters. Senators and Members can move motions of censure against the government or against individual ministers. On most sitting days in both Houses there is a session called Question Time at which Senators and Members address questions to the Prime Minister and other ministers. Senators and Members can also present petitions from their constituents. Both Houses have an extensive system of committees in which draft bills are debated, evidence is taken and public servants are questioned. There are also joint committees, composed of members from both Houses.
Relationship with the Government
A minister is not required to be a Senator or Member of the House of Representatives at the time of their appointment, but their office is forfeited if they do not become a member of either house within three months of their appointment.
This provision was included in the Constitution (section 64) to enable the inaugural Ministry, led by Edmund Barton, to be appointed on 1 January 1901, even though the first federal elections were not scheduled to be held until 29 and 30 March.
The provision was also used after the disappearance and presumed death of the Liberal Prime Minister Harold Holt in December 1967. The Liberal Party elected John Gorton, then a Senator, as its new leader, and he was sworn in as Prime Minister on 10 January 1968 (following an interim ministry led by John McEwen). On 1 February, Gorton resigned from the Senate to stand for the 24 February by-election in Holt's former House of Representatives electorate of Higgins. For 22 days (2 to 23 February inclusive) he was Prime Minister while a member of neither house of parliament.
On a number of occasions when Ministers have retired from their seats prior to an election, or stood but lost their own seats in the election, they have retained their Ministerial offices until the next government is sworn in.
Role of the Senate
The Constitution of Australia established the Senate as part of the new system of dominion government in newly federated Australia. From a comparative governmental perspective, the Australian Senate exhibits distinctive characteristics. Unlike upper houses in other Westminster system governments, the Senate is not a vestigial body with limited legislative power. Rather it was intended to play – and does play – an active role in legislation. Rather than being modelled solely after the House of Lords, as the Canadian Senate was, the Australian Senate was in part modelled after the United States Senate, by giving equal representation to each state. The Constitution intended to give less populous states added voice in a Federal legislature, while also providing for the revising role of an upper house in the Westminster system.
The constitutional text denies the Senate the power to originate or amend appropriation bills, in deference to the conventions of the classical Westminster system. Under a traditional Westminster system, the executive government is responsible for its use of public funds to the lower house, which has the power to bring down a government by blocking its access to supply – i.e. revenue appropriated through taxation. The arrangement as expressed in the Australian Constitution, however, still leaves the Senate with the power to reject supply bills or defer their passage – undoubtedly one of the Senate's most contentious and powerful abilities.
The ability to block supply was the origin of the 1975 Australian constitutional crisis. The Opposition used its numbers in the Senate to defer supply bills, refusing to deal with them until an election was called for both Houses of Parliament, an election which it hoped to win. The Prime Minister of the day, Gough Whitlam, contested the legitimacy of the blocking and refused to resign. The crisis brought to a head two Westminster conventions that, under the Australian constitutional system, were in conflict – firstly, that a government may continue to govern for as long as it has the support of the lower house, and secondly, that a government that no longer has access to supply must either resign or be dismissed. The crisis was resolved in November 1975 when Governor-General Sir John Kerr dismissed Whitlam's government and appointed a caretaker government on condition that elections for both houses of parliament be held. This action in itself was a source of controversy and debate continues on the proper usage of the Senate's ability to block supply and on whether such a power should even exist.
The blocking of supply alone cannot force a double dissolution. There must be legislation repeatedly blocked by the Senate which the government can then choose to use as a trigger for a double dissolution.
Members of the Australian Parliament do not have legal immunity: they can be arrested and tried for any offence. They do, however, have Parliamentary privilege: they cannot be sued for anything they say in Parliament about each other or about persons outside the Parliament. This privilege extends to reporting in the media of anything a Senator or Member says in Parliament. The proceedings of parliamentary committees, wherever they meet, are also covered by privilege, and this extends to witnesses before such committees.
There is a legal offence called contempt of Parliament. A person who speaks or acts in a manner contemptuous of the Parliament or its members can be tried and, if convicted, imprisoned. The Parliament used to have the power to hear such cases itself, and did so in the Browne–Fitzpatrick privilege case, 1955. This power has now been delegated to the courts. There have been few convictions. In May 2007, Harriet Swift, an anti-logging activist from New South Wales was convicted and reprimanded for contempt of Parliament, after she wrote fictitious press releases and letters purporting to be Federal MP Gary Nairn as an April Fools' Day prank.
Radio broadcasts of Parliamentary proceedings began on 10 July 1946. They were originally broadcast on Radio National. Since August 1994 they have been broadcast on ABC NewsRadio, a government-owned channel set up specifically for this function. It operates 24 hours a day and broadcasts other news items when parliament is not sitting.
The first televised parliamentary event was the historic 1974 Joint Sitting. Regular free-to-air television broadcasts of Question Time began in August 1990 from the Senate and February 1991 from the House of Representatives. One chamber's Question Time is televised live, and the other chamber's Question Time is recorded and broadcast later that day. Other free-to-air televised broadcasts include: the Treasurer's Budget speech and the Leader of the Opposition's reply to the Budget two days later; the opening of Parliament by the Governor-General; the swearing-in of Governors-General; and addresses to the Parliament by visiting heads of state.
Access to free extensive daily proceedings is now available live on the Internet.
Lower house primary, two-party and seat results since 1910
A two-party system has existed in the Australian House of Representatives since the two non-Labor parties merged in 1909. The 1910 election was the first to elect a majority government, with the Australian Labor Party concurrently winning the first Senate majority. A two-party-preferred vote (2PP) has been calculated since the 1919 change from first-past-the-post to preferential voting and subsequent introduction of the Coalition. ALP = Australian Labor Party, L+NP = grouping of Liberal/National/LNP/CLP Coalition parties (and predecessors), Oth = other parties and independents.

- Cory Bernardi resigned from the Liberal Party on 7 February 2017 and founded the Australian Conservatives.
- Bob Day resigned from the Senate on 1 November 2016.
- Sen Rodney Culleton left Pauline Hanson's One Nation on 19 December 2016. On 23 December the Federal Court ordered sequestration of his assets, which involved a declaration of bankruptcy, but with a 21-day stay on the order, to expire on 13 January 2017. Under Constitution s 44(iii) a bankrupt person is disqualified from sitting in the federal parliament. On 11 January, after receiving an official copy of the court's judgement, the President of the Senate declared Culleton's seat vacant. Culleton's appeal against this judgement was dismissed.
- On 7 November 2016 the Senate referred the questions of the eligibility of Day and Culleton, as well as the issue of what should be done if either of them is found to have been ineligible, to the High Court. On 3 February 2017 Court decided that, since Culleton's liability to a two-year sentence for larceny had been in place at the time of the 2016 election, he had been ineligible for election and that this was not affected by the subsequent annulment of that conviction; the Court also held that the resulting vacancy should be filled by a recount of the ballot, in a manner to be determined by a single Justice of the Court.
