List of Australian Leaders of the Opposition in the context of "Opposition (Australia)"

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).

The 1996 Australian federal election was held to determine the members of the 38th Parliament of Australia. It was held on 2 March 1996. All 148 seats of the House of Representatives and 40 seats of the 76-seat Senate were up for election. The Liberal/National Coalition led by Opposition Leader John Howard of the Liberal Party and coalition partner Tim Fischer of the National Party defeated the incumbent Australian Labor Party government led by Prime Minister Paul Keating in a landslide victory. The Coalition won 94 seats in the House of Representatives, the equal-largest number of seats won by a federal government to date (tied with Labor's win in 2025), and only the second time a party had won over 90 seats at a federal election; the first occurred in 1975.

The election marked the end of the five-term, 13-year Hawke-Keating Government that began in 1983. Howard was sworn in as the new prime minister of Australia on 11 March 1996, along with the First Howard Ministry. This election was the start of the 11-year Howard Government; the Labor party would spend this period in opposition and would not return to government until the 2007 election.
