In Australian parliamentary practice, the Opposition or the Official Opposition consists of the second largest party or coalition of parties in the Australian House of Representatives , with its leader being given the title Leader of the Opposition . The Opposition serves the same function as the official opposition in other Commonwealth of Nations monarchies that follow the Westminster conventions and practices. It is seen as the alternative government and the existing administration's main opponent in the Australian Parliament and at a general election. By convention, the Opposition Leader in the federal Parliament comes from the House of Representatives , as does the deputy, although the Government and Opposition may also both have leaders in the Senate . The Opposition is sometimes styled as His Majesty's Loyal Opposition to show that, although the group may be against the sitting government, it remains loyal to the Crown (the embodiment of the Australian state), and thus to Australia.
79-635: Opposition (55) Coalition Crossbench (18) [REDACTED] [REDACTED] The House of Representatives is the lower house of the bicameral Parliament of Australia , the upper house being the Senate . Its composition and powers are set down in Chapter I of the Constitution of Australia . The term of members of the House of Representatives is a maximum of three years from
158-688: A center squeeze , which may sometimes prevent the election of a Condorcet winner. Whilst the Marquis de Condorcet early on showed that it did not satisfy his Condorcet winner criterion , which it may fail under certain scenarios, instant-runoff voting satisfies many other majoritarian criteria, such as the majority criterion , mutual majority criterion and the Condorcet loser criterion . Advocates have argued these properties are positive, because voting rules should encourage candidates to focus on their core support or political base, rather than building
237-644: A "member of parliament" ("MP" or "member"), while a member of the Senate is usually referred to as a "senator". Under the conventions of the Westminster system , the government of the day and the prime minister must achieve and maintain the confidence of this House in order to gain and remain in power. The House of Representatives currently consists of 151 members, elected by and representing single member districts known as electoral divisions (commonly referred to as "electorates" or "seats"). The number of members
316-508: A broad coalition. They also note that in countries like the United Kingdom without primaries or runoff elections , IRV can prevent spoiler effects by eliminating minor-party candidates in early rounds, and that unlike plurality, it is not affected by the presence of duplicate candidates (clones) . In instant-runoff voting, as with other ranked voting rules, each voter orders candidates from first to last. The counting procedure
395-593: A candidate who nevertheless remains more preferred by voters. For example, in the 2009 Burlington, Vermont, mayoral election , if the Republican candidate who lost in the final instant runoff had not run, the Democratic candidate would have defeated the winning Progressive candidate. In that sense, the Republican candidate was a spoiler—albeit for an opposing Democrat, rather than some political ally—even though leading in first choice support. This also occurred in
474-480: A class of instant runoff- Condorcet hybrids. IRV is also completely immune to the burying strategy: ranking a strong opposition candidate lower can't get one's preferred candidate elected. Tactical voting in IRV seeks to alter the order of eliminations in early rounds, to ensure that the original winner is challenged by a stronger opponent in the final round. For example, in a three-party election where voters for both
553-692: A document, or later being found to have lied to or misled a committee. Anyone who attempts to influence a witness may also be found in contempt. Other powers include, the ability to meet throughout Australia, to establish subcommittees and to take evidence in both public and private hearings. Proceedings of committees are considered to have the same legal standing as proceedings of Parliament, they are recorded by Hansard , except for private hearings, and also operate under parliamentary privilege . Every participant, including committee members and witnesses giving evidence, are protected from being prosecuted under any civil or criminal action for anything they may say during
632-566: A hearing. Written evidence and documents received by a committee are also protected. Types of committees include: Standing committees , which are established on a permanent basis and are responsible for scrutinising bills and topics referred to them by the chamber; examining the government's budget and activities and for examining departmental annual reports and activities. Select committees , which are temporary committees, established in order to deal with particular issues. Domestic committees , which are responsible for administering aspects of
711-461: A lower "influence, prestige, and dignity" and to ensure the influence of the Senate in case of a joint sitting after a double dissolution. Another reason was to make it harder politically for the House of Representatives to be increased, thereby maintaining the smaller states over representation in the lower house due to their constitutional minimum of five seats. The requirements for territory seats are set via legislation, which currently requires that
790-411: A majority of votes. Two other books on American parliamentary procedure, The Standard Code of Parliamentary Procedure and Riddick's Rules of Procedure , take a similar stance. The term instant-runoff voting is derived from the name of a class of voting methods called runoff voting. In runoff voting voters do not rank candidates in order of preference on a single ballot. Instead a similar effect
869-616: A majority. Compared to a plurality voting system that rewards only the top vote-getter, instant-runoff voting mitigates the problem of wasted votes . However, it does not ensure the election of a Condorcet winner , which is the candidate who would win a direct election against any other candidate in the race. All forms of ranked-choice voting reduce to plurality when all ballots rank only one candidate. By extension, ballots for which all candidates ranked are eliminated are equivalent to votes for any non-winner in plurality, and considered exhausted ballots . Some political scientists have found
SECTION 10
#1732764925187948-415: A marginal candidate are strongly encouraged to instead vote for a more popular candidate who shares some of the same principles, since that candidate has a much greater chance of being elected and a vote for the marginal candidate will not result in the marginal candidate's election. An IRV method reduces this problem, since the voter can rank the marginal candidate first and the mainstream candidate second; in
1027-534: A particular inquiry is completed the members of the committee can then produce a report, to be tabled in Parliament, outlining what they have discovered as well as any recommendations that they have produced for the government to consider. The ability of the chambers of Parliament to establish committees is given in section 49 of the Constitution, which states that, "The powers, privileges, and immunities of
1106-747: A result of American influence, the term ranked-choice voting is often used in Canada as well. American NGO FairVote has promoted the terminology "ranked-choice voting" to refer to IRV, a choice that has caused controversy and accusations that the organization is attempting to obscure the existence of other ranked-choice methods that could compete with IRV. IRV is occasionally referred to as Hare's method (after Thomas Hare ) to differentiate it from other ranked-choice voting methods such as majority-choice voting , Borda , and Bucklin , which use weighted preferences or methods that allow voter's lower preference to be used against voter's most-preferred choice. When
1185-401: A result, the speaker often has to use the disciplinary powers granted to him or her under standing orders. Since 2015, Australian Federal Police officers armed with assault rifles have been present in both chambers of the federal Parliament. 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
1264-422: Is a single-winner , multi-round elimination rule that uses ranked voting to simulate a series of runoffs with only one vote. In each round, the candidate with the fewest votes is eliminated, and their votes are transferred to their next available preference until one of the options reaches a majority of the remaining votes. Instant runoff falls under the plurality-with-elimination family of voting methods, and
1343-540: Is achieved by using multiple rounds of voting. All multi-round runoff voting methods allow voters to change their preferences in each round, incorporating the results of the prior round to influence their decision, which is not possible in IRV. The runoff method closest to IRV is the exhaustive ballot . In this method—familiar to fans of the television show American Idol —one candidate is eliminated after each round, and many rounds of voting are used, rather than just two. Because holding many rounds of voting on separate days
1422-501: Is described in Robert's Rules of Order Newly Revised as an example of ranked-choice voting that can be used to elect officers. Robert's Rules note that ranked-choice systems (including IRV) are an improvement on simple plurality but recommend against runoff-based rules because they often prevent the emergence of a consensus candidate with broad support. The book instead recommends repeated balloting until some candidate manages to win
1501-450: Is generally expensive, the exhaustive ballot is not used for large-scale, public elections. A more practical form of runoff voting is the two-round system , which excludes all but the top-two candidates after the first round, rather than gradually eliminating candidates over a series of rounds. Eliminations can occur with or without allowing and applying preference votes to choose the final two candidates. A second round of voting or counting
1580-432: Is not fixed but can vary with boundary changes resulting from electoral redistributions , which are required on a regular basis. The most recent overall increase in the size of the House, which came into effect at the 1984 election , increased the number of members from 125 to 148. It reduced to 147 at the 1993 election , returned to 148 at the 1996 election , increased to 150 at the 2001 election , and stands at 151 as of
1659-559: Is only necessary if no candidate receives an overall majority of votes. This method is used in Mali, France and the Finnish and Slovenian presidential election. The contingent vote , also known as "top-two IRV", is the same as IRV, except that if no candidate achieves a majority in the first round of counting, all but the two candidates with the most votes are eliminated, and the second preferences for those ballots are counted. As in IRV, there
SECTION 20
#17327649251871738-555: Is possible to derive a two-party-preferred figure, where the votes have been allocated between the two main candidates in the election. In Australia, this is usually between the candidates from the Coalition parties and the Australian Labor Party . Under the Constitution, the governor-general has the power to appoint and dismiss the "Queen's Ministers of State" who administer government departments. In practice,
1817-410: Is the ability to summon people to attend hearings in order to give evidence and submit documents. Anyone who attempts to hinder the work of a Parliamentary committee may be found to be in contempt of parliament . There are a number of ways that witnesses can be found in contempt. These include refusing to appear before a committee when summoned, refusing to answer a question during a hearing or to produce
1896-423: Is then as follows: It is possible for a candidate to win an instant-runoff race without any support from more than half of voters, even when there is an alternative majority-approved candidate; this occurs when some voters truncate their ballots to show they do not support any candidates in the final round. In practice, candidates who do not receive a majority of votes in the first round usually do not finish with
1975-687: Is thus closely related to rules like the exhaustive ballot and two-round runoff system . IRV has found some use in national elections in several countries , predominantly in the Anglosphere . It is used to elect members of the Australian House of Representatives and the National Parliament of Papua New Guinea as well as the President of India , the President of Ireland , and the President of Sri Lanka . The rule
2054-582: 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 government, a predecessor of the modern-day Liberal Party of Australia , changed the lower house voting system to instant-runoff voting , which in Australia is known as full preferential voting, as of the subsequent 1919 election . This system has remained in place ever since, allowing
2133-711: The 1949 election , Bill Spooner was appointed a minister in the Fourth Menzies ministry on 19 December, however his term as a Senator did not begin until 22 February 1950. 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
2212-477: The 1972 election had the largest number of winners who would not have won under first past the post but still only 14 out of 125 seats filled were not won by the first-count leader. The effect of IRV on voter turnout is difficult to assess. In a 2021 report, researchers at New America , a think tank based in Washington, D. C., said it may increase turnout by attracting more and more diverse candidates, but
2291-400: The 2022 Alaska's at-large congressional district special election . If Republican Sarah Palin , who lost in the final instant runoff, had not run, the more centrist Republican candidate, Nick Begich, would have defeated the winning Democratic candidate, Mary Peltola . The system has had a mixed reception among political scientists and social choice theorists . Some have suggested that
2370-415: The 2022 Australian federal election . The House of Representatives chamber is designed to seat up to 172 members, with provision for an ultimate total of 240 to be accommodated. Each division elects one member using full-preferential instant-runoff voting . This was put in place after the 1918 Swan by-election , which Labor unexpectedly won with the largest primary vote and the help of vote splitting in
2449-576: The Australian Capital Territory and the Northern Territory have at least one member each. According to the Constitution, the powers of both Houses are nearly equal, with the consent of both Houses needed to pass legislation. The difference mostly relates to taxation legislation. In practice, by convention, the person who can control a majority of votes in the lower house is invited by the governor-general to form

Full-preference preferential voting re-elected the Hawke government at the 1990 election , the first time in federal history that Labor had obtained a net benefit from preferential voting. From 1949 onwards, the vast majority of electorates, nearly 90%, are won by the candidate leading on first preferences, giving the same result as if

A minister must be a senator or member of the House of Representatives at the time of their appointment, or become one within three months of their appointment.

After
2844-457: The left and right prefer the centrist candidate to stop the opposing candidate from winning, those voters who care more about defeating the opposition than electing their own candidate may cast a tactical first-preference vote for the centrist candidate. Proponents of IRV claim that IRV eliminates the spoiler effect, since IRV makes it safe to vote honestly for marginal parties. Under a plurality method, voters who sympathize most strongly with
2923-572: The single transferable vote (STV) method is applied to a single-winner election, it becomes IRV; the government of Ireland has called IRV "proportional representation" based on the fact that the same ballot form is used to elect its president by IRV and parliamentary seats by proportional representation (STV), but IRV is a non-proportional winner-take-all (single-winner) election method, while STV elects multiple winners. State law in South Carolina and Arkansas use "instant runoff" to describe
3002-480: The "alternative vote" (AV). Australians, who use IRV for most single winner elections, call IRV "preferential voting". While this term is widely used by Australians, it is somewhat of a misnomer . Depending on how "preferential" is defined, the term would include all voting systems, apply to any system that uses ranked ballots (thus both IRV and STV), or would exclude IRV (IRV fails positive responsiveness because ballot markings are not interpreted as "preferences" in

Federal judge Lance Walker rejected these claims, and the 1st circuit court denied Poliquin's emergency appeal. Often instant-runoff voting elections are won by the candidate who leads in first-count vote tallies so they choose the same winner as first-past-the-post voting would have. In Australia federal elections,

However, the baseline quota for the number of voters in an electorate is determined by the number of voters in the state in which that electorate is found. Consequently, the electorates of the smallest states and territories have more variation in

In practice, the Federal Executive Council meets solely to endorse and give legal force to decisions already made by the Cabinet. All members of

IRV is also sometimes vulnerable to a paradoxical strategy of ranking a candidate higher to make them lose, due to IRV failing the monotonicity criterion . Research suggests that IRV is very resistant to tactical voting. In a test of multiple methods, instant runoff was found to be the second-most-resistant to tactical voting, after
3555-560: The House chamber. Due to the unique role of what was then called the Main Committee, proposals were made to rename the body to avoid confusion with other parliamentary committees, including "Second Chamber" and "Federation Chamber". The House of Representatives later adopted the latter proposal. The concept of a parallel body to expedite Parliamentary business, based on the Australian Federation Chamber,

The Federation Chamber cannot, however, initiate or make a final decision on any parliamentary business, although it can perform all tasks in between. The Federation Chamber was created in 1994 as the Main Committee, to relieve some of
3713-448: The House of Representatives must be "as nearly as practicable, twice the number of the senators", according to section 24 of the Constitution. This requirement is known as the "nexus provision". This requirement was included in the Constitution in order to maintain the power of the Senate relative to the House of Representative: both due to the belief by the drafters of the Constitution that a numerically weaker Senate would inherently lead to
3792-608: The House's own affairs. These include the Selection Committee that determines how the House will deal with particular pieces of legislation and private members business and the Privileges Committee that deals with matters of parliamentary privilege. Legislative scrutiny committees , which examine legislation and regulations to determine their impact on individual rights and accountability. Joint committees are also established to include both members of

Parliamentary committees can be given a wide range of powers. One of the most significant powers

The House's well-established committee system is not always as prominent as the Senate committee system because of the frequent lack of Senate majority.

It is designed to be less formal, with a quorum of only three members: the deputy speaker of the House, one government member, and one non-government member. Decisions must be unanimous: any divided decision sends the question back to the House at large. The Federation Chamber
4187-550: The colour of eucalyptus trees. Also, unlike the House of Commons, the seating arrangement of the crossbench is curved, similar to the curved seating arrangement of the United States House of Representatives . This suggests a more collaborative, and less oppositional, system than in the United Kingdom parliament (where all members of parliament are seated facing the opposite side). Australian parliaments are notoriously rowdy, with MPs often trading colourful insults. As

In addition to the work of the main chamber, the House of Representatives also has a large number of committees which deal with matters referred to them by the main House. They provide the opportunity for all MPs to ask questions of ministers and public officials as well as conduct inquiries, examine policy and legislation. Once
4503-428: The first place. Spatial model simulations indicate that instant runoff rewards strategic withdrawal by candidates. Gibbard's theorem demonstrates that no (deterministic, non-dictatorial) voting method can be entirely immune from tactical voting. This implies that IRV is susceptible to tactical voting in some circumstances. In particular, when there exists a Condorcet winner who IRV fails to elect, voters who prefer

By contrast, the only period in recent times during which the government of the day has had a majority in the Senate was from July 2005 (when the senators elected at the 2004 election took their seats) to July 2008 (when the senators elected at the 2007 election took their seats). Hence, votes in

In practice that means that the leader of the party (or coalition of parties) with a majority of members in the House becomes the prime minister , who then can nominate other elected members of the government party in both the House and the Senate to become ministers responsible for various portfolios and administer government departments.

#17327649251874898-656: The impact would be realized most significantly by getting rid of the need for primaries. The overall impact on diversity of candidates is difficult to detect. Instant-runoff voting derives its name from the way the ballot count simulates a series of runoffs, similar to an exhaustive ballot system , except that voters do not need to turn out several times to vote. It is also known as the alternative vote, transferable vote, ranked-choice voting (RCV), single-seat ranked-choice voting, or preferential voting (but use of some of those terms may lead to misunderstanding as they also apply to STV.) Britons and New Zealanders generally call IRV
4977-477: The likely event that the fringe candidate is eliminated, the vote is not wasted but is transferred to the second preference. However, when the third-party candidate is more competitive, they can still act as a spoiler under IRV, by taking away first-choice votes from the more mainstream candidate until that candidate is eliminated, and then that candidate's second-choice votes helping a more-disliked candidate to win. In these scenarios, it would have been better for
5056-442: The lower house and thus only the party with a majority in the lower house can govern. In the current Australian party system, this ensures that virtually all contentious votes are along party lines, and the government party usually has a majority in those votes in the lower house. The opposition party's main role in the House is to present arguments against the government's policies and legislation where appropriate and attempt to hold
5135-405: The most recent redistribution. Full preferential voting is used in elections, a type of instant-runoff voting . A full allocation of preferences is required for a vote to be considered formal. This allows for a calculation of the two-party-preferred vote . Under section 24 of the Constitution, each state is entitled to members based on a population quota determined from the "latest statistics of

Meanwhile, all the states except Tasmania have electorates approximately within the same 10% tolerance, with most electorates holding 85,000 to 105,000 voters.

On the crossbench , the Australian Greens gained three seats, upping their total from one to four, while
5372-476: The practice of having certain categories of absentee voters cast ranked-choice ballots before the first round of an election and counting those ballots in any subsequent runoff elections. This method was first discussed by the Marquis de Condorcet in 1788, who quickly rejected it after showing it would often eliminate a candidate preferred by a majority of voters. IRV was later independently reinvented by Thomas Hare (of England) and Carl Andrae (of Denmark) in
5451-436: The same votes had been counted using first-past-the-post voting . The highest proportion of seats (up to 2010) won by the candidate not leading on first preferences was the 1972 federal election , with 14 of 125 seats not won by the plurality candidate. The main elements of the operation of preferential voting for single-member House of Representatives divisions are as follows: Following the full allocation of preferences, it

Parties and candidates often encourage their supporters to participate in these preference deals using How-to-vote cards explaining how to use their lower rankings to maximize the chances of their ballot helping to elect someone in the preference deal before it may exhaust. Instant runoff may be manipulable via strategic candidate entry and exit, reducing similar candidates' chances of winning. Such manipulation does not need to be intentional, instead acting to deter candidates from running in
5609-458: The system contributes to higher rates of spoiled votes , partly because the ballot marking is more complex. Most jurisdictions with IRV do not require complete rankings and may use columns to indicate preference instead of numbers. In American elections with IRV, more than 99 percent of voters typically cast a valid ballot. A 2015 study of four local US elections that used IRV found that inactive ballots occurred often enough in each of them that
5688-420: The system does not do much to decrease the impact of wasted votes relative to plurality. Research has found IRV causes lower confidence in elections and does not substantially affect minority representation, voter turnout , or long-run electoral competition . Opponents have also noted a high rate of repeals for the system. Governor Paul LePage and Representative Bruce Poliquin claimed, ahead of

This is the same bracketing effect exploited by Robinette and Tideman in their research on strategic campaigning, where a candidate alters their campaign to cause a change in voter honest choice, resulting in the elimination of
5846-492: The traditional sense. Under IRV (and STV), secondary preferences are used as back-up preferences/contingency votes). Jurisdictions in the United States such as San Francisco , Minneapolis , Maine , and Alaska have tended to use the term "ranked-choice voting" in their laws that apply to IRV contests. The San Francisco Department of Elections claimed the word "instant" in the term "instant-runoff voting" could confuse voters into expecting results to be immediately available. As
5925-435: The winner of each election did not receive a majority of votes cast in the first round. The rate of inactive ballots in each election ranged from a low of 9.6 percent to a high of 27.1 percent.
