It is used as a staging point for Australian Defence Force (ADF) operations within Australia and internationally. The aerodrome has also been used for co-ordination of relief efforts following Tropical Cyclones and other natural disasters, notably Cyclone Larry in 2006.
The Royal Flying Doctor Service has one of its nine Queensland bases at Townsville Airport.
