The Special Air Service Regiment, officially abbreviated SASR and commonly known as SAS, is a special forces unit of the Australian Army. Formed in 1957 as a company, it was modelled on the British SAS with which it shares the motto "Who Dares Wins". Expanded to a regiment in August 1964, it is based at Campbell Barracks, in Swanbourne, a suburb of Perth, Western Australia, and is a direct command unit of the Special Operations Command.
