Camden Airport — Cobbitty, Australia

Camden Airport occupies farmland at Cobbitty on Sydney's southwestern fringe, and its history as one of Australia's oldest continuously used airfields stretches back to the 1930s, when it served as an early hub for the country's fledgling aviation industry. CDU today functions primarily as a general-aviation and flight-training base, hosting the Historical Aircraft Restoration Society's vintage warbird collection and periodic air shows that draw enthusiasts from across New South Wales. Successive governments have periodically studied Camden as a potential site for Sydney's long-discussed second airport, though that role ultimately went elsewhere. Suburban growth in the surrounding Macarthur region has steadily encroached on the airport's once-rural surroundings.
