The 1903 Australian federal election was held in Australia on 16 December 1903. All 75 seats in the House of Representatives, and 19 of the 36 seats in the Senate were up for election. The incumbent Protectionist Party minority government led by Prime Minister Alfred Deakin retained the most House of Representatives seats of the three parties and retained government with the parliamentary support of the Labour Party led by Chris Watson. The Free Trade Party led by George Reid remained in opposition.
The election outcome saw a finely balanced House of Representatives, with the three parties each holding around a third of seats − the Protectionists on 26, the Free Traders on 24 and Labour on 22. This term of parliament saw no changes in any party leadership but did see very significant and prolonged debates, with three changes in government: the Protectionist minority government fell in April 1904 to be replaced by a minority Labour government, which lasted until August 1904, before falling in turn. Labour was replaced by a minority Free Trader government, which finally fell in July 1905 to be replaced by the Protectionists, who continued until the 1906 election and beyond. The Free Traders remained in opposition throughout this eventful period with the exception of Labour forming the opposition for the first time during the period of the Free Trader minority government. Additionally, the Watson government was the world's first Labour Party government at a national level.
