Ossima Airport (OSG)

Ossima Airport (OSG) is a remote domestic airstrip located in the Sandaun (West Sepik) Province of Papua New Guinea, situated approximately 15 miles (25 km) south of Vanimo. The facility functions as a basic regional airfield and does not feature a formal commercial passenger terminal building. It serves as a vital infrastructure link for the local community, supporting the transport of essential supplies, missionary aviation, and government charter flights. Facilities at the airport are extremely minimal, reflecting its role as a minor rural landing strip. There are no on-site commercial amenities such as retail shops, restaurants, or public restroom facilities, and the waiting area typically consists of a basic open-air shelter. Travelers are advised to be completely self-sufficient and to bring their own food and water, as standard airport services are not available at this location. The airfield features a single 2,297-foot grass and grey clay runway (14/32) and operates strictly under Visual Flight Rules (VFR) during daylight hours. Due to the nature of the runway surface, operations can be significantly impacted by local weather conditions, particularly heavy tropical rainfall. Ground transportation is informal, with most travel to and from the airstrip being arranged through local community networks or specific charter providers.
