National Service Act 1951

The National Service Act 1951 was Australian federal legislation providing for the compulsory call-up of males turning 18 on or after 1 November 1950, for service training of 176 days. Trainees were required to remain on the Reserve of the Commonwealth Military Forces (CMF) for five years from initial call up. Men could nominate the service in which they wished to be trained. Those nominating the Navy or the Air Force were considered only if they volunteered for service outside Australia. The first call-up notice was issued on 12 April 1951.

Between 1951 and 1959 over 500,000 men registered, 52 intakes were organised and some 227,000 men were trained.

In 1957 National Service with the Navy and the Air Force was discontinued. Registration remained compulsory but the intake to the Army was cut to almost a third (12,000 trainees) by instituting a ballot for selection. On 24 November 1959 Cabinet decided that National Service call-ups should be terminated and that arrangements for the January 1960 intake would be cancelled
