The Special Air Service Regiment, officially abbreviated SASR though commonly known as the SAS, is an elite special operations force of the Australian Army. Formed in 1957, it was originally modelled on the British SAS sharing the motto, "Who Dares Wins", and draws on the experiences of Australian Services Reconnaissance Department, independent companies, Coastwatchers and M and Z Special Units during World War II. Based at Campbell Barracks, in Swanbourne, a suburb of Perth, Western Australia, the regiment is a direct command unit of the Special Operations Command. It has been involved in operations in Borneo during the Indonesia–Malaysia confrontation, the Vietnam War, East Timor, Iraq and Afghanistan.
