Newcastle Airport — Williamtown, Australia

Fighter jets and airliners share the same runway at Newcastle Airport, since the civilian terminal operates alongside RAAF Base Williamtown, home to Royal Australian Air Force squadrons flying F-35 and earlier F/A-18 aircraft, a dual-use arrangement common at Australian regional airports but unusually prominent here given the base's strategic importance. Carrying the code NTL, the airport serves Newcastle and the broader Hunter Region north of Sydney, an area historically built on coal mining and steel that has diversified in recent decades into wine tourism around the Hunter Valley and beach destinations along the coast. It ranks as one of the busier airports in New South Wales after Sydney, with domestic carriers connecting the region to Melbourne, Brisbane, and the state capital. The single long runway, sized originally for military operations, gives NTL more capacity than its passenger numbers alone would suggest necessary.
