The spouse of the Prime Minister of Australia is a position that until 24 June 2010 was occupied exclusively by women, thus the spouse was often known as the Prime Minister's wife. The incumbent Prime Minister (since 24 June 2010) is Julia Gillard and her domestic partner is Tim Mathieson. She is the only Australian Prime Minister who has never married. John McEwen was a widower at the time of becoming Prime Minister, and he remarried after leaving the office.
