Woomera, established as a restricted access township in 1947, is located in the south east corner of the Woomera Prohibited Area (WPA), which encloses a large active test range used to evaluate missile, ordnance, and aerospace systems. Woomera Defence Village is an Australian Defence Force (ADF) facility supporting the Royal Australian Air Force (RAAF) Woomera Test Range. The Test Range incorporates airspace above the WPA, along with technologically advanced tracking and monitoring equipment. Within the land boundary of the WPA are RAAF Woomera Airfield, Evetts Field, the Nurrungar Prohibited Area, and Camp Rapier. Woomera village is in the 'outback' desert area of South Australia, approximately 488km north of Adelaide. An easement runs through the WPA allowing public transit on the Trans-Australian Railway, The Ghan, and the Stuart Highway. Travellers are prohibited from leaving these routes. In 1982 restrictions on public access to Woomera township were lifted, so allowing the town to develop as a tourist destination .
