Government (30) - (1 seat minority) Liberal (23) [i] Country Party (7)
Changes in composition This is a list of members of the Australian Senate from 1965 to 1968.
[1] Half of its members were elected at the 9 December 1961 election and had terms starting on 1 July 1962 and finishing on 30 June 1968; the other half were elected at the 5 December 1964 half Senate election and had terms starting on 1 July 1965 and finishing on 30 June 1971.
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.
