Scuba Diving in Gulf of Papua & Western Province

About Gulf of Papua & Western Province

The Gulf of Papua and the Western Province are the least-dived part of the country, dominated by the enormous Fly River and its sediment-laden outflow, which limits regular scuba diving to scientific and expedition efforts. The Fly River Delta is, however, a fascinating brackish-water environment where unique macro critters adapted to low salinity and soft substrate can be found, a stark contrast to the coral reefs elsewhere in the country. There are no regular dive operators in the region, and access is by special permit, research collaboration, or liveaboard transit, so this area is best considered a frontier for naturalists and expedition divers rather than a holiday destination. Its inclusion reflects the full geographic range of Papua New Guinea's underwater environments, from pristine coral to strange river-mouth ecology.

Highlights

• ✓Fly River Delta: a unique brackish-water environment with specialised macro critters and soft substrate.
• ✓Scientific and expedition diving: the only realistic way to explore this sediment-rich region.
• ✓Contrast ecology: a stark counterpoint to PNG's coral reef diving.

Getting There

The Gulf of Papua and Fly River Delta are reached from Port Moresby by light aircraft or expedition vessel, with the delta itself accessible only via special permit, research collaboration, or liveaboard transit. There are no regular dive operators, and logistics are entirely bespoke, so this region is unsuitable for casual visitors and should be approached as a scientific or expedition endeavour.
