The simple name, Woomera, refers to a town located in South Australia's Far North region, approximately 446 kilometres (277 mi) north of Adelaide, the capital of the State of South Australia. In common usage, "Woomera" also refers to the wider "Woomera Range Complex" (WRC), a huge Defence systems testing range covering an area of approximately 122,000 square kilometres (47,000 sq mi) (an area roughly the size of England).
Woomera township is part of an Australian Defence Force base (RAAF Base Woomera) which, along with the Woomera Test Range (WTR), forms the larger entity known as the "Woomera Range Complex" (WRC). The WRC is the latest name for this historic aerospace testing range and was promulgated by Chief of Air Force (CAF) in June 2014. RAAF Base Woomera came into existence on 12 January 2015, and No.20 (Woomera) Squadron, was officially reformed as the WRC base combat support squadron at a ceremony at Woomera on 1 April 2015. Woomera Range Headquarters is the primary organisation which operates the facility on behalf of Chief of Air Force.
Woomera Village (as it has always been known) is a Defence owned and operated facility. RAAF Base Woomera, when it was established in January 2015, also included the RAAF Woomera Aerodrome, which is approximately 6 km north of Woomera Village. The aerodrome lies within the 'Red Zone' of the Woomera Prohibited Area (WPA) and public access to this part of the base is not permitted. Woomera Village, however, is within a "Green Zone" of the WPA and thus public access to the facilities and services of Woomera, including the several museums located in this historic site, is permitted year round.
