Darwin
Formed in June 1940, RAAF Base Darwin was very rapidly at the front line of Australia's defences at the outbreak of war in the Pacific. Darwin and its satellite fields housed a multitude of Australian and US units, operating throughout the South-West Pacific. Following the end of World War II, Darwin became an important transit stop for military movements throughout Asia, including use as a transport hub to support operations in Vietnam. Today, Darwin's main operations occur during defence exercises.
