In 1949, Australian units based with the British Commonwealth Occupation Force (BCOF) in Japan were among the first UN personnel to be deployed in South Korea. After the administrative support role of BCOF in Japan to the fighting forces in Korea had been decided in November 1950, the title BCFK appeared. The position of BCFK Commander-in-Chief was always held by Australian Army officers, the first being Lt Gen. Sir Horace Robertson. Liaison between the Commonwealth C-in-C and the UN high command was provided by a subordinate headquarters in Tokyo.
