The Inspector-General of Intelligence and Security (IGIS) is an independent statutory office holder who reviews the activities of the agencies which collectively comprise the Australian Intelligence Community (AIC).
While the IGIS focus is on the operational activities of the AIC agencies, the AIC is also subject to review by the Parliamentary Joint Committee on Intelligence and Security (PJCIS), as well as the Australian National Audit Office (ANAO). Certain ASIO assessments can be appealed to the Administrative Appeals Tribunal (AAT). Proceedings can also be instituted against AIC agencies in the Courts.
The AIC agencies are also the subjects of specific legislation and scrutiny by the relevant responsible Ministers. Both the Inspector-General of Intelligence and Security and the Director-General of the Office of National Assessments are responsible to the Prime Minister.
The Directors-General of the Australian Security Intelligence Organisation and the Australian Secret Intelligence Service are responsible to the Attorney-General and the Minister for Foreign Affairs and Trade respectively.
The Directors of the Defence Signals Directorate, the Defence Intelligence Organisation and the Defence Imagery and Geospatial Organisation are each responsible to the Minister for Defence.
The office of the IGIS is also subject to external scrutiny through senate Estimates hearings on its budget allocations and issues relevant to its functions.
