Sirebi Airstrip (ICAO: AYSB) is a small, remote airstrip located in Papua New Guinea, serving the local community of Sirebi. Like many airstrips in Papua New Guinea, it plays a vital role in connecting an otherwise isolated community to larger population centers, given the country's challenging terrain and limited road infrastructure. The airstrip is typical of rural PNG facilities, likely consisting of a single unpaved or gravel runway capable of accommodating small, light aircraft operated by missionary, charter, or regional operators. Access to essential supplies, medical services, and personnel depends heavily on air transport at locations such as this. Detailed operational data, including runway length, elevation, and operator information, is not widely published in accessible aviation databases, reflecting the limited documentation common for remote PNG airstrips.
