Between 1951 and 1959, 18-year-old men were required to register for national service.
Over 220-thousand underwent six months of compulsory military training in the army, navy or air force.
The men got to choose in which branch they served.
In 1964 a National Service Scheme was reintroduced, with the government granted new powers to send national servicemen overseas.
This was significant, as at that time Australian soldiers was involved in the Vietnam War.
All 20-year old males were required to register with the Department of Labor and National Service, with conscripts selected in a random birthday ballot.
Exemptions were granted to Aboriginal and Torres Strait Islander people, the medically unfit as well as theology students.
Under the scheme, which would run until 1972, almost 64-thousand young men were conscripted to serve two-years full-time in the army.
More than 15,000 of the conscripts served in Vietnam.
