Julia Gillard in the context of "We Can Do It!"

The Australian Labor Party (ALP), also 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 the 2022 federal election, and with political branches active in all the Australian states and territories, they currently hold government in New South Wales, South Australia, Victoria, Western Australia, and the Australian Capital Territory. As of 2025, Queensland, Tasmania and Northern Territory are the only states or territories where Labor currently forms the opposition. It is the oldest continuously operating political party in Australian history, having been established on 8 May 1901 at Parliament House, Melbourne, the meeting place of the first Federal Parliament.

The ALP is descended from the labour parties founded in the various Australian colonies by the emerging labour movement. Colonial Labour parties contested seats from 1891, and began contesting federal seats following Federation at the 1901 federal election. In 1904, the ALP briefly formed what is considered the world's first labour party government and the world's first democratic socialist or social democratic government at a national level. At the 1910 federal election, Labor became the first party in Australia to win a majority in either house of the Australian parliament. In every election since 1910 Labor has either served as the governing party or the opposition. There have been 13 Labor prime ministers and 10 periods of federal Labor governments, including under Billy Hughes from 1915 to 1916, James Scullin from 1929 to 1932, John Curtin from 1941 to 1945, Ben Chifley from 1945 to 1949, Gough Whitlam from 1972 to 1975, Bob Hawke from 1983 to 1991, Paul Keating from 1991 to 1996, Kevin Rudd from 2007 to 2010 and 2013, Julia Gillard from 2010 to 2013, and Anthony Albanese since 2022.

A federal election was held on 21 August 2010 to elect members of the 43rd Parliament of Australia. The incumbent centre-left Australian Labor Party led by Prime Minister Julia Gillard won a second term against the opposition centre-right Liberal Party of Australia led by Opposition Leader Tony Abbott and Coalition partner the National Party of Australia, led by Warren Truss, after Labor formed a minority government with the support of three independent MPs and one Australian Greens MP.

Labor and the Coalition each won 72 seats in the 150-seat House of Representatives, four short of the requirement for majority government, resulting in the first hung parliament since the 1940 election. Six crossbenchers held the balance of power. Greens MP Adam Bandt and independent MPs Andrew Wilkie, Rob Oakeshott and Tony Windsor declared their support for Labor on confidence and supply. Independent MP Bob Katter and National Party of Western Australia MP Tony Crook declared their support for the Coalition on confidence and supply. The resulting 76–74 margin entitled Labor to form a minority government. The Prime Minister, government ministers and parliamentary secretaries were sworn in on 14 September 2010 by the Governor-General Quentin Bryce. In November 2011, Coalition MP and Deputy Speaker Peter Slipper replaced Labor MP Harry Jenkins as Speaker of the House of Representatives, increasing Labor's parliamentary majority from 75–74 (not including Jenkins as he was unable to vote on legislation due to his role as Speaker) to 76–73 (not including Slipper as he was unable to vote on legislation due to his role as Speaker).
