The National Service Act 1964 (Cth) is a repealed amendment of the Parliament of the Commonwealth of Australia, passed on 24 November 1964. It amended the National Service Act 1951 to require 20-year-old males to serve in the Army for a period of twenty-four months of continuous service (reduced to eighteen months in 1971) followed by three years in the Reserve.
The Defence Act 1965 amended the Defence Act 1903 in May 1965 to provide that conscripts could be obliged to serve overseas, and in March 1966 Prime Minister Harold Holt announced that National Servicemen would be sent to Vietnam to fight in units of the Australian Regular Army.
