Joint Intelligence Organisation (Australia)

The Joint Intelligence Organisation (JIO) was an Australian government intelligence agency, responsible for the analysis of defence and foreign intelligence. The foreign intelligence assessment functions of JIO were assumed by the Office of National Assessments (ONA) in 1977 and the JIO was fully replaced by the Defence Intelligence Organisation (DIO) in 1990. The JIO was staffed by civilian officers of the Department of Defence, foreign service officers of the Department of Foreign Affairs and Trade, and service personnel from the Australian Army, the Royal Australian Navy, and the Royal Australian Air Force.

The JIO also maintained the National Assessments Staff (NAS) which supported the National Intelligence Committee (the predecessor to the National Intelligence Coordination Committee) until 1977 when it was assumed by the Office of National Assessments. The NAS was responsible for preparing long–range analytical assessments of international issues.

Following World War II, defence and foreign intelligence functions were shared between the Royal Australian Navy, the Australian Army and the Royal Australian Air Force. There also existed a Joint Intelligence Bureau (JIB) within the Department of Defence responsible for geographic, infrastructure, economic, scientific and technical intelligence in the Asia-Pacific region.
