A double dissolution is a procedure permitted under the Australian Constitution to resolve deadlocks in the bicameral Parliament of Australia between the House of Representatives and the Senate. A double dissolution is the only circumstance in which the entire Senate can be dissolved.

The 1975 Australian constitutional crisis, also known simply as the Dismissal, culminated on 11 November 1975 with the dismissal from office of the prime minister, Gough Whitlam of the Australian Labor Party (ALP), by Sir John Kerr, the Governor-General who then commissioned the leader of the Opposition, Malcolm Fraser of the Liberal Party, as prime minister. It has been described as the greatest political and constitutional crisis in Australian history.
