text: The 1975 Australian federal election was held in Australia on 13 December 1975. All 127 seats in the House of Representatives and all 64 seats in the Senate were up for election, due to a double dissolution.
  Malcolm Fraser had been commissioned as caretaker prime minister following the dismissal of Gough Whitlam's three-year-old Labor government by Governor-General Sir John Kerr, on 11 November 1975. The same day, Fraser advised an immediate double dissolution, in accordance with Kerr's stipulated conditions (see 1975 Australian constitutional crisis).
  The Coalition of Fraser's Liberal Party of Australia and Doug Anthony's National Country Party secured government in its own right, winning the largest majority government to date in Australian history. The Liberals actually won a majority in their own right, with 68 seats–the first time that the main non-Labor party had done so since adopting the Liberal banner in 1944. Although Fraser had no need for the support of the National Country Party, the Coalition was retained. It was also the first time a party won over 90 seats at an Australian election. This was the last federal election the Coalition won more than 50% of the primary vote.
