Julia Gillard (pictured) was sworn in as the first female prime minister of Australia after incumbent Kevin Rudd declined to contest a leadership spill in the Labor Party.

Julia Eileen Gillard is an Australian former politician who served as the 27th prime minister of Australia from 2010 to 2013. She held office as the leader of the Labor Party (ALP), having previously served as the 13th deputy prime minister from 2007 to 2010. She is the first and only woman to hold either office.

The prime minister of Australia is the head of government of the Commonwealth of Australia. The prime minister is the chair of the Cabinet of Australia and thus the head of the federal executive government. Under the principles of responsible government, the prime minister is both responsible to and a member of the Commonwealth Parliament. The current prime minister is Anthony Albanese of the Australian Labor Party, who assumed the office on 23 May 2022.

Kevin Michael Rudd is an Australian diplomat and former politician who served as the 26th prime minister of Australia from 2007 to 2010 and in 2013. He held office as the leader of the Labor Party from 2006 to 2013. Since 2023, Rudd has served as the 23rd ambassador of Australia to the United States.

A leadership spill occurred in the Australian Labor Party on 24 June 2010. Kevin Rudd, the prime minister of Australia, was challenged by Julia Gillard, the deputy prime minister of Australia, for the leadership of the Australian Labor Party. Gillard won the election unopposed after Rudd declined to contest, choosing instead to resign. Gillard was duly sworn in as prime minister by Quentin Bryce, the Governor-General, on 24 June 2010 at Government House, becoming Australia's first female prime minister.
