Air traffic control
Air traffic control in Australia is provided by two independent organisations, one civilian and one military. The civilian provider is Airservices Australia, which controls civilian airfields and airspace. The military provider is the Royal Australian Air Force (RAAF), which controls military airfields and adjoining airspace. This includes Australian Army and Royal Australian Navy aviation bases. Some airfields in Australia are categorised as Joint User airfields, where there are both civilian and military operations based at the airfield. Normally, Joint User airfields have air traffic control provided by the RAAF.
