Lawata Passage Dive Site
Site Overview
Lawata Passage, within the Milne Bay – Muck & Reef Diving of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. A drift dive through a current-funelled passage where big pelagics, tuna, Spanish mackerel, and occasionally whale sharks race the tide. Geographically the site features passage and wall and drop-off formations built from coral and rock substrate, dropping from a shallow top of around 8 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 30 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Dogtooth Tuna (Gymnosarda unicolor), Spanish Mackerel (Scomberomorus sp.), Whale Shark (Rhincodon typus), Grey Reef Shark (Carcharhinus amblyrhynchos), Barracuda (Sphyraena barracuda), Bigeye Trevally (Caranx sexfasciatus), 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 Lawata Passage one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Lawata Passage is best enjoyed as part of a boat programme out of Alotau, 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.
Dive Briefing
"Your dive at Lawata Passage begins with a negative descent along the mooring line or wall, depending on the current on the day. You negative-enter and drift through the passage, watching the blue for tuna and mackerel, then ascend with the current as it eases near the exit. Plan to spend the deepest portion of the dive along the passage between 8 and 22 metres, where the coral is most colourful and the larger fish congregate. Hook in on rock if the current pins you, and stay with your guide so the group drifts together. Mid-water, watch the blue beyond the wall for passing Dogtooth Tuna (Gymnosarda unicolor) and other pelagics, and keep an eye on your no-decompression limits given the depths involved. Ascend slowly with a safety stop at five metres to off-gas safely. Because Lawata Passage can experience strong currents and occasionally reduced visibility after heavy rain, dive with a surface marker buoy and always follow your operator's site-specific briefing and emergency plan."

Traveler Notes
Who is this for?
Lawata Passage is aimed at advanced divers holding at least a Advanced Open Water certification, and it suits those comfortable managing strong conditions and maintaining neutral buoyancy along passage terrain. Photographers, marine-life enthusiasts, and experienced divers will find it especially rewarding, while experienced drift divers will love it, while those new to current should build skills elsewhere first. Divers who prefer calm, shallow, zero-current conditions should choose one of Papua New Guinea's sheltered house reefs or lagoons instead, and anyone without the recommended certification should complete a check-out dive with a local operator first.
For Non-Divers
Non-divers can snorkel the shallows or watch the passage from the boat while divers drift the current.
