Tennant Creek Airport (IATA: TCA, ICAO: YTNK) is a regional airport serving Tennant Creek, a town in the Northern Territory of Australia. Located roughly midway between Darwin and Alice Springs on the Stuart Highway, it provides a vital air link for a remote community that is otherwise dependent on long road or rail journeys. The airport handles a modest volume of passenger traffic, primarily through scheduled regional services connecting Tennant Creek to Darwin and Alice Springs. It also supports general aviation, charter flights, emergency medical services, and freight operations critical to the region. As with many remote Australian airports, Tennant Creek Airport plays an essential role in connecting Indigenous communities and supporting mining, tourism, and emergency services across the Barkly region of the Northern Territory.
