Members of the Australian Senate, 1956–1959

This is a list of members of the Australian Senate from 1956 to 1959. Half of its members were elected at the 9 May 1953 election and had terms starting on 1 July 1953 and finishing on 30 June 1959; the other half were elected at the 10 December 1955 election and had terms starting on 1 July 1956 and finishing on 30 June 1962. The process for filling casual vacancies was complex. While senators were elected for a six-year term, people appointed to a casual vacancy only held office until the earlier of the next election for the House of Representatives or the Senate.
