This is a list of members of the Australian Senate from 1975 to 1978. The 13 December 1975 election was a double dissolution of both houses, with all 127 seats in the House of Representatives, and all 64 seats in the Senate up for election. Malcolm Fraser had been commissioned as prime minister following the dismissal of Gough Whitlam’s Labor government by Governor-General Sir John Kerr, on 11 November 1975. The same day, Fraser advised the calling of the election, in accordance with Kerr’s stipulated conditions. Thus the Liberal Party of Australia, led by Fraser, with Coalition partner the National Country Party, led by Doug Anthony, went to the election as a caretaker government. The election resulted in the Coalition securing government with a 30-seat swing away from Labor in the House of Representatives.
In accordance with section 13 of the Constitution, following a double dissolution of Parliament, the terms for state senators commence on 1 July preceding the election, i.e., on 1 July 1975. Half the senators representing each state were allocated three-year terms ending on 30 June 1978 and the other half served full six-year terms ending on 30 June 1981. The territories (Northern Territory and Australian Capital Territory} were to be represented in the Senate for the first time following the 1975 election. The terms of senators representing the territories commenced on the date of the election and ended at the dissolution of the House of Representatives for the December 1977 election.
