DEERS sites are located in Alice Springs, Darwin, and Canberra.  However, the Canberra and Darwin sites are the only publicly accessible DEERS locations to update and issue a Common Access Card (CAC) and dependent ID cards.  Personnel assigned outside of these areas will need to travel to either Canberra or Darwin at your parent unit’s expense to receive a new ID card.  For consideration, you may try to obtain an updated ID card at your current location in order to have a card that lasts throughout your assignment in Australia.  Feel free to use the Exception to Policy memo to obtain a new ID card prior to your PCS.
