Signals intelligence (Sigint) role
The Defence Signals Directorate (DSD) provides foreign signals intelligence, known as Sigint, to the Australian Defence Force and Australian Government to support military and strategic decision-making.
Support to military operations has been and continues to be a primary goal of Sigint. Sigint has improved the safety and effectiveness of our forces in military and peacekeeping operations from the Second World War to the present day.
Sigint now also supports a broad range of government policy development and decision-making. In an increasingly complex world, our work helps the government to make well-informed decisions on political, defence and security issues that affect Australians and Australia’s interests.
The Australian Government sets our intelligence priorities through the National Security Committee of Cabinet. Our governance and accountability framework sets strict legal boundaries for our work, including privacy rules to protect the privacy of Australians. Details of our Sigint work are necessarily secret.
