Joint Intelligence Bureau In the post-World War II period, the military intelligence and strategic assessments functions were shared between the Navy, Army and Air Force intelligence directorates and the Joint Intelligence Bureau (JIB) from 1947 to 1969. JIB was responsible for geographic, infrastructure and economic intelligence – mainly in Australia's region. In 1957, JIB's responsibilities were expanded to include scientific and technical intelligence.
Joint Intelligence Organisation In 1969, most of the foreign assessment elements of the three armed services were merged to form the Joint Intelligence Organisation (JIO). The
Royal Commission on Intelligence and Security (also called the first Hope Commission) in 1977 recommended the establishment of the
Office of National Assessments (ONA) as an independent statutory agency to provide all-source assessments on international political, strategic and economic developments to the Prime Minister and to assume the foreign intelligence assessment role of JIO. JIO was then reoriented to focus more closely on defence intelligence and strategic interests. The second Hope Commission endorsed these arrangements in 1984. In 1989, counterterrorism was added to JIO's responsibilities.
Defence Intelligence Group On the 1st of September 2020, following the Defence Intelligence Review of 2019–2020, the Defence Intelligence Group (DIG) was created, folding the DIO in as one of its divisions. The DIG reports to the Chief of Defence Intelligence; a position which is now also the head of the DIO. ==Overview==
