Goulburn Airport — , Australia

GUL is Goulburn Airport, located near Goulburn in New South Wales, Australia, one of the country's oldest inland cities. The airport primarily supports general aviation, flight training, and gliding activities, taking advantage of the region's favorable weather conditions for soaring, alongside limited charter operations. Goulburn's proximity to both Sydney and Canberra places GUL within a busy corridor of southeastern Australian air traffic, though the airport itself remains a smaller regional facility rather than a scheduled airline hub. The surrounding area is known for sheep and cattle grazing, and GUL occasionally supports agricultural aviation activities in addition to its recreational flying community.
