It’s a fair question: why does Australia have a national Signals Intelligence (Sigint) agency? This book addresses this question, among others, to explain the antecedents of Sigint and cyber for a contemporary audience.

For a long time, the Sigint story has been kept secret – until now. What does it do and why is it controversial? How significant are its ties with key partners, the United States, the United Kingdom, Canada and New Zealand, to this arrangement?

This is the first book to offer a consolidated history of Australian Sigint and cyber in Australia, covering the period all the way from Federation through to the present.

Blaxland, Professor of International Security and Intelligence Studies in the Stragetic and Defence Studies Centre, and Birgin present a broad panorama giving a sense of the scale and the scope of Sigint and its role in the advent of cyber.

Blaxland and Birgin, who during a 30-year career at the Department of Foreign Affairs and Trade placed focus on national security and intelligence, traverse the royal commissions and reviews that shaped Australia’s intelligence community in the 20th century and consider the advent and the impact of cyber.
