Before December 1941 members of the Australian Military Force (AMF - home service only) could join the Australian Imperial Force (AIF - eligible for overseas service). However once their AMF unit was mobilized they could not leave their unit to join the AIF. In July 1942 this prohibition was lifted. This subcollection will progressively collate the stories of the 400 plus AMF soldiers, serving on Rottnest who elected to join the AIF. The basis of inclusion is their place of enlistment being recorded as "Rottnest" in their record of service.
