Aua Island Airport (IATA: AUI, ICAO: AYND) is a small airstrip serving Aua Island, located in Manus Province, Papua New Guinea. The airport provides essential air access to this remote island community, which would otherwise be largely isolated from the rest of the country. The airport operates limited scheduled and charter services, primarily connecting Aua Island to regional hubs within Papua New Guinea. It plays a critical role in supporting the movement of people, mail, and essential supplies to the island. Given its remote and small-scale nature, the airport has minimal infrastructure and handles very low passenger volumes. It is typical of many small airstrips found throughout Papua New Guinea's island provinces.
