Australian Labor Party

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.

The Labor Party is often called the party of unions due to its close ties to the labour movement in Australia and historical founding by trade unions, with the majority of Australian trade unions being affiliated with the Labor Party. The party's structure allocates 50% of delegate representation at state and national conferences to affiliated unions, with the remaining 50% to rank-and-file party members. At the federal and state/colony level, the Australian Labor Party predates both the British Labour Party and the New Zealand Labour Party in party formation, government, and policy implementation. Internationally, the ALP is a member of the Progressive Alliance, a network of progressive, democratic socialist and social democratic parties, having previously been a member of the Socialist International.

In standard Australian English, the word labour is spelt with a u. However, the political party uses the spelling Labor, without a u. There was originally no standardised spelling of the party's name, with Labor and Labour both in common usage. According to Ross McMullin, who wrote an official history of the Labor Party, the title page of the proceedings of the Federal Conference used the spelling "Labor" in 1902, "Labour" in 1905 and 1908, and then "Labor" from 1912 onwards. In 1908, James Catts put forward a motion at the Federal Conference that "the name of the party be the Australian Labour Party", which was carried by 22 votes to 2. A separate motion recommending state branches adopt the name was defeated. There was no uniformity of party names until 1918 when the Federal party resolved that state branches should adopt the name "Australian Labor Party", now spelt without a u. Each state branch had previously used a different name, due to their different origins.

Although the ALP officially adopted the spelling without a u, it took decades for the official spelling to achieve widespread acceptance. According to McMullin, "the way the spelling of 'Labor Party' was consolidated had more to do with the chap who ended up being in charge of printing the federal conference report than any other reason". Some sources have attributed the official choice of Labor to influence from King O'Malley, who was born in the United States and was reputedly an advocate of English-language spelling reform; the spelling without a u is the standard form in American English.

Andrew Scott, who wrote "Running on Empty: 'Modernising' the British and Australian Labour Parties", suggests that the adoption of the spelling without a u "signified one of the ALP's earliest attempts at modernisation", and served the purpose of differentiating the party from the Australian labour movement as a whole and distinguishing it from other British Empire labour parties. The decision to include the word "Australian" in the party's name, rather than just "Labour Party" as in the United Kingdom, Scott attributes to "the greater importance of nationalism for the founders of the colonial parties".

The Australian Labor Party has its origins in the Labour parties founded in the 1890s in the Australian colonies prior to federation. Labor tradition ascribes the founding of Queensland Labour to a meeting of striking pastoral workers under a ghost gum tree (the Tree of Knowledge) in Barcaldine, Queensland in 1891. The 1891 shearers' strike is credited as being one of the factors for the formation of the Australian Labor Party. On 9 September 1892 the Manifesto of the Queensland Labour Party was read out under the well known Tree of Knowledge at Barcaldine following the Great Shearers' Strike. The State Library of Queensland now holds the manifesto; in 2008 the historic document was added to UNESCO's Memory of the World Australian Register and, in 2009, the document was added to UNESCO's Memory of the World International Register. The Balmain, New South Wales branch of the party claims to be the oldest in Australia. However, the Scone Branch has a receipt for membership fees for the Labour Electoral League dated April 1891. This predates the Balmain claim. This can be attested in the Centenary of the ALP book.^{[citation needed]} Labour as a parliamentary party dates from 1891 in New South Wales and South Australia, 1893 in Queensland, and later in the other colonies.

The first election contested by Labour candidates was the 1891 New South Wales election, when Labour candidates (then called the Labor Electoral League of New South Wales) won 35 of 141 seats. The major parties were the Protectionist and Free Trade parties and Labour held the balance of power. It offered parliamentary support in exchange for policy concessions. The United Labor Party (ULP) of South Australia was founded in 1891, and three candidates were that year elected to the South Australian Legislative Council. The first successful South Australian House of Assembly candidate was John McPherson at the 1892 East Adelaide by-election. Richard Hooper however was elected as an Independent Labor candidate at the 1891 Wallaroo by-election, while he was the first labor member of the House of Assembly he was not a member of the newly formed ULP.
