The quickest way to search for a family member’s service record is to be as organised as possible. Record as much information as you can, but also any missing evidence. Your family member’s full name, date of birth and service number is an ideal start, but both official and personal documents can be useful.
Please visit the Accessing information page on the Defence website for a full list of information that will help you find a service record.
Information is also available at: The National Archives of Australia, which contains records of service in the Australian armed forces, dating principally from Federation in 1901. Reference enquiries may be answered by the Australian War Memorial's Research Centre via info@awm.gov.au.
