Australia's political landscape has traditionally been dominated by two major parties, the Australian Labor Party and the Liberal Party of Australia, forming a de facto two-party system. This system has been relatively stable, with these parties gaining at least 70% of the primary vote in every election between 1910 and 2019. However, in recent years, there has been a shift towards voting for candidates from smaller parties or independent politicians. Political parties in Australia aim to influence change by forming governments or oppositions, scrutinising government actions, and introducing issues to the national agenda. They also play a crucial role in the committee system, influencing voter registration, campaigning, and participating in the electoral process. Australia's unique electoral system, with compulsory voting and a mix of voting methods, further shapes how political parties navigate the landscape to gain influence and ultimately, power.

Coalition governments
Australia's political landscape has been dominated by organised, national political parties since federation. The country operates as a two-party system, with the Australian Labor Party and the Coalition being the two dominant forces. The Coalition is an alliance between the Liberal Party of Australia and the National Party of Australia (formerly the Country Party). The Coalition has existed in some form since 1923, with the partnership between the two current parties dating back to 1946.
The Liberal Party is a centre-right party that broadly represents businesses, the middle classes, and many rural people. The National Party, on the other hand, represents rural and agricultural interests and is generally more socially conservative than the Liberal Party. When the Liberal Party and its predecessors have been in coalition with the National Party, the leader of the National Party has had the right to be the deputy prime minister and to nominate their party's members of the Coalition ministry.
The Coalition has been a stable force in Australian politics for long periods, with the parties being formally cooperative in both government and opposition. This stability has, however, been punctuated by breaks in the agreement, including the 1934 and 1987 federal elections, which the parties contested separately. The most recent break in the coalition occurred after the Coalition's landslide defeat in the 2025 federal election, where the National Party did not enter into a formal coalition arrangement with the Liberal Party.
Despite these breaks, the Coalition has played a significant role in influencing change in Australia. The two parties have cooperated on federal election campaigns, run joint Senate tickets in most states, and avoided running candidates against each other in the House of Representatives. The Coalition has also been in government at both the federal level and in individual states, allowing them to implement their policies and agenda.

Voting systems
Voting in Australia is compulsory, and the country is known for its invention of the secret ballot, or the 'Australian ballot'. This means that, unlike in some other countries, voter turnout in Australia is consistently high. For instance, the 2019 figure of 92% was considered low by Australian standards. Those who fail to vote without a valid reason must pay a $20 penalty.
The Australian political system is dominated by two parties: the social-democratic Labor Party and the conservative Liberal-National Coalition. The Coalition is technically made up of two parties: the Liberals and the more rural-focused National Party. However, for most intents and purposes, the Coalition is regarded as a single party.
The Labor Party and the Coalition have jointly held nearly all seats in the House of Representatives in the post-war era. However, in recent decades, there has been a shift towards voters giving their first preference to candidates outside of these two major parties. At the 2022 federal election, 31% gave their preference to a non-major party candidate.
The voting system in Australia is preferential, meaning that voters rank candidates in order of preference (1, 2, 3, etc.). For a vote to be valid, all candidates listed on the ballot paper must be ranked. If a candidate wins more than half of the first-preference votes, they are elected outright. If not, the candidate with the fewest votes is eliminated, and their votes are transferred to each voter's next preference. This process continues until one candidate has a majority of the votes.
The Senate, on the other hand, is elected using the single transferable voting system of proportional representation. This has resulted in a greater presence of minor parties in the Senate.
To receive federal public funding, a political party must be registered under the Electoral Act, which requires that they have at least 1,500 members. All nominations for party-endorsed candidates must be signed by the Registered Officer of a registered party. Candidates for either house must formally nominate with the Electoral Commission.

Campaigning and advertising
Traditional ground campaigning remains highly effective in engaging voters. This involves face-to-face interactions, attending community events, and door-to-door canvassing, allowing politicians and campaigners to connect personally with voters and understand their concerns.
Advertising is a powerful tool for political parties to reach a wide audience and convey their messages. It includes television, radio, print, and online advertisements. Political parties create targeted campaigns with specific themes and slogans to appeal to voters' interests and values. Negative campaigning, or criticising opposing parties, has also been a longstanding tactic in Australian politics.
The advent of new technologies has expanded the avenues for campaigning and advertising. Digital platforms, such as social media and online videos, enable political parties to engage with voters directly and instantly share information and updates. Social media, in particular, allows for more interactive communication and the ability to target specific demographics with tailored messages.
To maintain transparency and prevent external influence, Australia has implemented financial disclosure requirements. Voters can access information about the financial dealings of political parties and candidates, ensuring compliance with foreign donation rules. These rules aim to safeguard Australian elections from foreign interference and maintain the integrity of the democratic process.
While campaigning and advertising are crucial for political parties to reach and influence voters, it is essential to consider the potential for voter confusion or dissatisfaction. Some communication methods and channels may overwhelm or mislead voters. Thus, voters are encouraged to conduct personal research and reflect on various sources of information before casting their votes.

Party ideologies
Australia's political landscape has been dominated by a two-party system, with the Australian Labor Party (centre-left) and the Liberal Party of Australia (centre-right) as the two major players. The Labor Party, formed in 1893, has its roots in the Australian labour movement and organised workers. It has been a significant force in Australian politics since 1901 and is currently the governing party at the federal level and in multiple states. On the other hand, the Liberal Party, founded in 1944, represents businesses, the middle classes, and many rural people. It is the modern incarnation of a conservative group that has existed since the merger of the Protectionist Party and the Free Trade Party.
The Liberal Party often forms a coalition with the National Party, previously known as the Country Party, which represents rural and agricultural interests. This coalition is known as the Coalition. The two parties have officially merged in Queensland to form the Liberal National Party, and in the Northern Territory, the Country Liberal Party is affiliated with both the Liberals and the Nationals. The Nationals generally hold more socially conservative views than the Liberals.
While the two-party system has been relatively stable, third parties and independent politicians have gained traction in recent years. The Australian Greens, for example, have received more than 10% of the vote in several federal elections. Minor parties play a role in introducing issues to the national agenda, and independent politicians can sometimes influence the formation of governments.
The Australian political parties' ideologies span the spectrum from left to right, with the Labor Party generally considered a left-wing or socialist party, and the Liberal Party and its coalition partners occupying the centre-right to right-wing positions. These parties influence change in Australia by forming governments or oppositions, implementing laws, scrutinising government actions, and contributing to parliamentary decisions.

Party influence in parliament
Australia's political landscape has been dominated by organised, national political parties since federation. The country operates as a constitutional monarchy, with a parliamentary democracy in the Westminster tradition. It has a two-party system, with the Australian Labor Party and the Liberal Party of Australia as the two dominant parties. The Labor Party is Australia's oldest political party, established federally in 1901. The Liberal Party is a coalition of centre-right parties with a base in business and the middle classes, and it has been predominantly conservative and moderate.
The power of political parties in parliament is largely determined by the number of members they have. Parliamentary parties are influential because their members work as a team, typically voting the same way on issues and bills. The more members a party has, the more powerful they are when voting together. However, if members of a party publicly disagree or vote against their party ('crossing the floor'), this can lead to a loss of power and influence.
Parties with enough members elected to form a government are called major parties, while those that do not have enough members to form a government or opposition are called minor parties. Minor parties can still exert influence by introducing issues to get them on the national agenda. Coalitions are formed when two or more political parties agree to work together to create a bigger group in parliament, usually voting the same way while retaining their separate identities.
Political parties play a crucial role in the electoral process by helping to select party candidates, assisting with election campaigns, and scrutinising the counting of votes. They also influence public policies, which are shaped by various factors including public opinion, economic conditions, scientific findings, technological changes, interest groups, NGOs, and business lobbying.
In recent years, there has been a shift among Australian voters towards preferring candidates from minor parties or independent politicians. This has resulted in major parties having to form agreements with minor parties or independents to govern.
