ASD began as the Defence Signals Bureau in Melbourne on 1 April 1947, tasked with intercepting foreign communications and protecting the communications security of Australia’s military and government departments.
However, ASD’s story stretches back even further to the Second World War. Since then, ASD has met any challenge: global conflicts, technological revolutions, and pandemics. ASD continues to adapt and innovate and is committed to serving the nation and protecting its interests in an ever-changing world.
