Ema Reef Dive Site

Site Overview

Ema Reef, within the Kimbe Bay (New Britain – Coral Hotspot) of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. A dramatic wall with black coral, barracuda, reef sharks, and large groupers patrolling the edge of the drop-off. Geographically the site features wall and drop-off and ledge formations built from coral and rock substrate, dropping from a shallow top of around 10 metres to a maximum depth of about 40 metres, with an average working depth near 22 metres. Visibility is typically excellent, ranging from 15 to 32 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Barracuda (Sphyraena barracuda), Grey Reef Shark (Carcharhinus amblyrhynchos), Giant Grouper (Epinephelus lanceolatus), Black Coral (Antipatharia), Hawksbill Turtle (Eretmochelys imbricata), Anthias (Pseudanthias 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 Ema Reef one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Ema Reef is best enjoyed as part of a boat programme out of Kimbe, 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.
