The Australian labour movement began in the early 19th century and since the late 19th century has included industrial and political wings. Trade unions in Australia may be organised on the basis of craft unionism, general unionism, or industrial unionism. Almost all unions in Australia are affiliated with the Australian Council of Trade Unions (ACTU), many of which have undergone a significant process of amalgamations, especially in the late 1980s and early 1990s. The leadership and membership of unions hold and have at other times held a wide range of political views, including socialist, democratic and right-wing views.

The Australian Labor Party (ALP), also commonly known as the Labor Party or simply Labor, is the major centre-left political party in Australia and one of two major parties in Australian politics, along with the centre-right Liberal Party of Australia. The party has been in government since being elected at the 2022 federal election, and with political branches in each state and territory, they currently form government in New South Wales, Queensland, South Australia, Victoria, Western Australia, the Australian Capital Territory, and the Northern Territory. As of 2023, Tasmania is the only state or territory where Labor forms the opposition. It is the oldest continuous political party in Australian history, being established on 8 May 1901 at Parliament House, Melbourne, the meeting place of the first federal Parliament.
