Senate composition at 1 July 1959 Government (32) - (1 seat majority) Liberal (25) Country Party (7)
This is a list of members of the Australian Senate from 1959 to 1962.
[1] Half of its members were elected at the 10 December 1955 election and had terms starting on 1 July 1956 and finishing on 30 June 1962; the other half were elected at the 22 November 1958 election and had terms starting on 1 July 1959 and finishing on 30 June 1965.
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.
