Description
The ASD had its beginnings during the World War II, when Australian military personnel were called on to intercept and decode Japanese radio signals as part of the South-West Pacific campaign lead by General MacArthur. After the war, the Australian government created the Defence Signals Bureau to continue the work of exploiting foreign communications, as well as providing communications security in the armed services and government departments.
During the intervening decades the ASD went through many iterations and name changes as it adapted and evolved to the security needs of the nation. Finally in May 2013 the title Australian Signals Directorate was chosen to reflect its whole-of-government role in supporting Australias national security. As the ASD celebrates seventy-five years of service and protection, they also look towards the future as Australias cyber protectors in the digital age.
