Intelligence accountability in Australia balances compliance and bodies whose systematic focus is on efficacy and financial review with independent intelligence reviews, commissions, and inquiries that focus on efficacy. Australia differs insofar as it is not subject to a constitutionally or supranationally enshrined civil right regime. A diversity of mechanisms, ranging from parliamentary committees and executive bodies to periodic independent reviews, fashion an oversight system that drives innovation. From the three Royal Hope Commissions to regular inquiries into the National Intelligence Community, Australia’s independent in-depth periodic reviews, inquiries, and commissions have a track-record of shaping and spurring change and innovation in the scope and structure of accountability across its broader intelligence and security community. The Australian tradition of independent expert intelligence reviews, commissions, and inquiries offsets the lack of accountability bodies dedicated to reviewing for efficacy and innovation. The chapter reviews the member organizations of the Australia’s National Intelligence Community, the strategic environment that has informed intelligence and accountability in Australia, national security threats as seen by Australia, as well as Australia’s systematic approach to reviewing and innovating its intelligence accountability architecture. It consists of the Inspector General of Intelligence and Security, the Parliamentary Joint Committee on Intelligence and Security, and the Independent National Security Law Monitor. Although similar to the United States Office of the Director of National Intelligence and the United Kingdom’s Joint Intelligence Organization, Australia’s Office of National Intelligence is quite unique insofar as neither the US and UK equivalents nor comparable offices in Canada and the New Zealand have an analogous accountability function. These mechanisms balance existing independent review mechanisms with mandates to review legislation and compliance, propriety, administration.
