Jack Warren Corey was born in Mount Gambier, South Australia on 9 January 1909. He enlisted in the Army on 6 January 1941 from Prospect, SA. After training in Cauldfield, Victoria, he embarked later that year for overseas service with 8 Divisional Ammunition Sub Park, arriving in Johor, Malay around November. Following the fall of Singapore in February 1942, he was interned by the Japanese in Selarang Barracks, Changi, and spent some time during 1943 in Thailand and Burma working on the railway and building bridges. He was liberated from Changi in early to mid 1945 and returned to Australia on HMAT Duntroon in September, before being discharged early the following year. He became treasurer of the South Australian branch of the Ex-Prisoner of War Association when it formed, and remained associated with it until his death in 1962.
