Conditions & Currents

Samarai Wharf is situated in the China Strait, an area known for its notorious tidal currents. These currents are a defining feature of the dive site, constantly bringing in nutrients that support the abundant marine life. Divers should anticipate mild to moderate currents, which can vary in strength with the tides. While these currents are crucial for the ecosystem's vitality, they necessitate careful dive planning and appropriate experience. Entry and exit strategies should account for potential drift, and divers may find themselves moving along with the current. Visibility at the site is generally good to excellent, often ranging from 25 to 40 meters, despite the currents, as the waters are continuously refreshed. This dynamic environment makes for an engaging dive but requires divers to be comfortable with current management.

Dive profile & how the dive runs

A typical dive at Samarai Wharf begins with a boat drop directly onto the site, allowing divers to descend quickly onto the historical wharf piles. The dive often follows the remaining eastern section of the wharf, exploring the structures that are heavily encrusted with corals and sponges. Divers progress along the pilings, paying close attention to the vibrant macro life hiding within the growth, as well as the schooling fish that congregate around the structures. Depth will vary as you navigate the wharf, but most exploration occurs in shallower ranges, allowing for extended bottom time. The strong currents of the China Strait influence the dive, making it often a drift experience along the wharf, with divers carefully managing buoyancy and position. The turn point is flexible, often determined by air consumption or current conditions, with the safety stop conducted in the shallowest parts of the structure or as a drift in the blue, depending on the boat's retrieval strategy.

Underwater photography

Samarai Wharf presents excellent opportunities for both macro and wide-angle photography, though macro is particularly rewarding due to the concentration of critters. For macro, a 60mm or 100mm lens is ideal for capturing frogfish, seahorses, and nudibranchs nestled among the wharf piles and corals. External strobes are essential to bring out the true colors of the abundant soft corals and invertebrates in what can be shaded areas beneath the wharf structures. Wide-angle photographers can utilize a 10-17mm fisheye or similar lens to capture the entire scope of the encrusted pilings and the swirling schools of baitfish and larger pelagics. Maintaining excellent buoyancy is crucial, especially when currents are present, to avoid disturbing the silty bottom and to keep subjects in focus. Be mindful of potential reflections from the surface, adjusting strobe positions to minimize backscatter, especially in the shallower sections.

Getting there & logistics

Access to Samarai Wharf typically involves flying into Port Moresby, the capital of Papua New Guinea, and then taking a connecting flight to Alotau, located in Milne Bay Province. From Alotau, most divers transfer to liveaboards which operate itineraries covering Milne Bay, including Samarai. Liveaboard trips to this region often range from 7 to 10 days, allowing exploration of multiple diverse sites. While specific permits for diving Samarai Wharf itself might not be separately charged, liveaboard packages typically include all necessary fees for the itinerary. It is advisable to confirm with your chosen operator regarding any local community fees or environmental levies that might apply. Milne Bay is historically significant for diving, being one of the first areas in PNG explored by divers, making it a well-established liveaboard destination.

Safety & environment

Diving at Samarai Wharf, especially with its potential for strong currents in the China Strait, necessitates adherence to strict safety protocols. Divers should be proficient in drift diving techniques and maintain excellent buoyancy control. A recompression chamber is located in Port Moresby, making evacuation from the remote Milne Bay region a complex and potentially lengthy process. Therefore, comprehensive dive insurance, including coverage for emergency medical evacuation, is absolutely essential. Always dive with a surface marker buoy (SMB) and know how to deploy it, as currents can separate divers from the boat. Briefings should cover emergency procedures and rendezvous points. While the wharf environment is generally safe, divers should avoid touching marine life or disturbing the historical structures. Divers are encouraged to stay well hydrated and dive within their training and comfort limits.
