Tsoi Island Bommies Dive Site

Site Overview

Tsoi Island Bommies, within the Kavieng & New Ireland – Pelagic & Walls of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. Isolated bommies with dense fish life, moray eels, lionfish, and nudibranchs, a colourful macro and reef dive. Geographically the site features bommie and reef and plateau formations built from coral and rock substrate, dropping from a shallow top of around 5 metres to a maximum depth of about 30 metres, with an average working depth near 16 metres. Visibility is typically excellent, ranging from 12 to 28 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Moray Eel (Gymnothorax sp.), Lionfish (Pterois volitans), Nudibranch (Nudibranchia), Clownfish (Amphiprion sp.), Anthias (Pseudanthias sp.), Octopus (Octopus sp.), alongside dense reef fish, invertebrates, and the soft and hard corals that blanket the reef. The mix of nutrient-rich currents and Papua New Guinea's remote, well-protected reefs makes Tsoi Island Bommies one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Tsoi Island Bommies is best enjoyed as part of a boat programme out of Kavieng, and it rewards wide-angle photographers, naturalists, and experienced drift divers alike. Papua New Guinea's strong community-based conservation ethos and remoteness help keep the reef pristine, so divers are asked to maintain exemplary buoyancy and respect the fragile marine environment at all times.
