 After a spell in civilian life following the war, Malley joined the Royal Australian Air Force (RAAF) in 1925, serving with No. 3 Squadron. He became an aviation adviser to China in 1931, and worked closely with Madame Chiang Kai-shek, Soong Mei-ling, from 1937. Malley was able to observe air tactics in the Sino-Japanese War at first hand, though his reports were given little weight in Australia. Returning home in 1940, he served in intelligence roles with the RAAF and later the Commonwealth government. After the war he bought a plantation in Fiji, where he died in 1961.
