About this site
The Catalina Wreck lies off Biak Island in Biak Numfor Regency, on the western edge of Cenderawasih Bay in West Papua. Biak saw heavy fighting during World War II between Allied and Japanese forces, and wreckage from that campaign is scattered around the island's coastline and reefs, with this site named for a downed PBY Catalina flying boat. It rests at a maximum depth of around 100 metres, making it a technical dive.
