Why does Australia have a national signals intelligence agency? What does it do and why is it controversial? And how significant are its ties with key partners, the United States, the United Kingdom, Canada and New Zealand, to this arrangement?

Revealing Secrets: An Unofficial History of Australian Signals Intelligence and the Advent of Cyber (University of New South Wales Press, 2023) co-authored by John Blaxland and Clare Birgin is a compelling account of Australian Signals intelligence, its efforts at revealing the secrets of other nations, and keeping ours safe. It brings to light those clever Australians whose efforts were for so long entirely unknown or overlooked. In unearthing this integral, if hidden and little understood, part of Australian statecraft, this book increases our understanding of the past, present and what lies ahead.

John Blaxland is Professor of International Security and Intelligence Studies in the Strategic and Defence Studies Centre (SDSC), Coral Bell School of Asia Pacific Affairs at the Australian National University (ANU). He is a Senior Fellow of the Higher Education Academy and a Fellow of the Royal Society of New South Wales. He is also formerly a military intelligence officer, Head of SDSC and Director of the ANU Southeast Asia Institute.
