Sebuku Airport (ICAO: WAOG) is a small domestic airport located in Sekapung, within the Kotabaru Regency of South Kalimantan Province, Indonesia. It serves the relatively isolated Sebuku area on the island of Borneo, providing essential air connectivity to communities that would otherwise face lengthy overland or river travel. The airport operates at a limited scale, primarily supporting regional flights and charter services that link the area to larger centers in Kalimantan. Given the remote geography of the region, air transport plays a critical role in local logistics and accessibility. Infrastructure at Sebuku Airport is modest, reflecting the low passenger volumes typical of rural Indonesian airstrips. It is managed under Indonesia's broader network of regional and remote airfields overseen by the Directorate General of Civil Aviation.
