John McCauley (1899–1989) was a senior commander in the
Royal Australian Air Force. He served as
Chief of the Air Staff from 1954 to 1957. A
Duntroon graduate, McCauley spent four years in the
Australian Military Forces before transferring to the RAAF in 1924. Having been promoted to
group captain in 1940, he was posted to
Singapore in June 1941 to take charge of all RAAF units defending the area. He earned praise for his efforts in attacking invading Japanese forces before the
fall of Singapore, and for his dedication in evacuating his men. He was later appointed to a senior operational role with the
Royal Air Force's
2nd Tactical Air Force in Europe, where he saw out the rest of the war. In 1947 he was promoted to
air vice marshal and appointed
Chief of Staff at
British Commonwealth Occupation Force Headquarters in Japan. He took up the position of Chief of the Air Staff in January 1954, and was
knighted a year later. During his tenure in the RAAF's senior role, McCauley focused on potential deployments to Southeast Asia—particularly
Vietnam—and threats from the north, commencing redevelopment of
RAAF Base Darwin and recommending purchase of a light
supersonic bomber to replace the Air Force's
English Electric Canberra. After retiring from military life in March 1957, he chaired various community and welfare organisations. (
