An independent politician is a person who has served in a political office while not affiliated to any political party. Many of these have either resigned or been expelled from membership in political parties, and some have gone on to form their own political parties over time. In some cases members of parliament sit as an Independent while still holding party leadership. This can be for a multitude of reasons including Expulsion from party room, deregistration of party and suspension of membership.

In Australia, the federal and state governments all operate on a bicameral parliament, with a House of Representatives and a Senate each. Control of each house is formed by either a majority parliament, where a single party or a coalition of parties, holds enough seats to hold power through an electoral term in their own right. When a party is unable to win enough seats in an election, this is known as a "hung parliament", the larger parties are required to meet with smaller third parties and independents in order to make compromises and agreements in order to have a majority of seats, known as forming a minority government. Most elections in Australian history have resulted in Majority governments. In every case where there have been minority governments, the balance of power has been predominantly in the hands of Independent members of parliament, meaning the individual is not attached to, or affiliated with, a political party.

There are numerous reasons why someone may stand for office as an independent:

• Parties only run a single candidate in the House of Representatives, in order to limit campaign costs and complexity. Some candidates attempt to become a candidate for a party in the pre-selection stage, and are unsuccessful. Instead of putting their support behind the successful pre-selectees, some choose to transition their efforts into an independent candidacy for office.
• Some independent politicians come from party backgrounds, and have either voluntarily withdrawn from parties due to factional or values-based misalignment or in protest of certain political actions, or have been removed by the party for similar reasons.
• Some independent politicians may not find enough common ground with the parties available, either from the positioning on the political spectrum, or the effectiveness in fulfilling their electoral mandate, and believe that standing apart from a party will prove more effective.

All politicians in Australia are still required to fulfil their obligations, if elected, regardless of whether they are independent or are part of a political party. All are also afforded the opportunity to speak on behalf of their electorate or district, if a member of the house of representatives, or state or region, if a member of the senate.

Before 2022 independents were not often elected to the federal Parliament of Australia. Historically independents were more commonly elected to state parliaments. In 2022 seven new independents were elected to the House of Representatives of whom only one was previously active in one of the traditional political parties; many of these were known as teal independents, a loose collective of social progressives challenging moderate Liberal seats. Historically, many independents were former members of one of Australia's main parties, the Australian Labor Party, the Liberal Party of Australia and the National Party of Australia. On 16 July 2013 a political party named the Australian Independents was registered with the Australian Electoral Commission. It was deregistered on 4 February 2016.^[1]
