The story of the first 25 years of Australia's national signals intelligence organisation, told for the first time.

'This story has never been told, because in the secret world we could not, and cannot, share what we do all day, even
with family and loved ones.' - from the foreword by Rachel Noble, Director-General, Australian Signals Directorate
At the end of World War II, it was clear that the nation must never again find itself entering a major war without a national
intelligence capability. The Factory tells the story of how Australia's talented signals intelligence amateurs took an ad hoc
wartime organisation and made it a national agency that became a highly regarded member of the 'five eyes' signals
intelligence system.
Founded in 1947 as the Defence Signals Branch, the organisation built upon the foundations put in place by the interwar
Royal Australian Navy and wartime signals intelligence agencies, particularly Central Bureau Brisbane, which comprised
personnel from all five eyes nations. Today's Australian Signals Directorate continues the work of protecting the interests
of the nation and its allies.
This is the story of the people who did the everyday work of capturing and analysing foreign signals. It reveals how they
approached the complexity of world politics and managed massive technological change, from the days of radio
transmissions to high-capacity machine systems and computing during the Vietnam War.
