From 1945 to 1975, the Australian Army always served overseas as a junior partner in a coalition, usually as part of a British Commonwealth force. This was the case during the occupation of Japan and the Korean War and under British command in Malaya and Borneo. However, the Vietnam War highlighted several problems for the junior partner in an American-dominated alliance. Relations remained cordial throughout the war in South Vietnam, especially at the individual level. However, stress points soon emerged that had the potential to damage the relationship and adversely affect intelligence collection, analysis and sharing.
