The 2/12th Field Ambulance was an Australian military unit of the Second Australian Imperial Force, serving during World War II. During their six years of service, over 200 soldiers were killed, the highest figure for a non-combatant unit in Australian history. The majority of the unit's casualties were suffered during the sinking of the hospital ship "Centaur" in May 1943. During the war, the 2/12th deployed personnel in support of Australian combat operations against the Japanese on Ambon, Timor and in Borneo before being disbanded in 1946.
