Dive sites in Papua New Guinea

Situated at an exposed point in Milne Bay, this drift site features a submerged reef ridge that plunges into deep open water. Currents sweep past the headland, drawing dense aggregations of pelagic predators and shoaling fish to the drop-off.

Named after Australian underwater photographer Kevin Deacon, this classic Milne Bay site sits along the sheltered northern coast of the peninsula. The reef starts right below the surface with dense fields of staghorn and plate corals before dropping into a dramatic slope cut by gullies and overhangs. Giant sea fans and sponges coat the deeper limestone walls, providing shelter for macro oddities and schooling reef fish.

Dinah's Beach at Lauadi is historically recognized as the birthplace of muck diving, popularized by liveaboard pioneer Bob Halstead in the late twentieth century. The underwater topography features a dark volcanic sand slope scattered with patches of coral rubble, fallen logs, and detached bommies. Divers scour the dark substrate for cryptic macro species that thrive in the nutrient-dense coastal wash.

Rising out of the deep waters of Astrolabe Bay, this isolated volcanic seamount acts as a magnet for pelagic marine life. Strong ocean currents wash over the pinnacle, attracting large predatory fish and pelagic schools that circle the summit plateau.

Resting along a sloping sandy seabed off the Kokopo shoreline, Rapopo Wreck serves as an artificial reef encrusted with encrusting sponges, soft corals, and hydroids. The hull structure provides shelter for macro critters and reef fish, making it a popular dive site accessible directly from the resort beachfront or via a short boat ride.

Located in the rich waters of Milne Bay, Sponge Heaven is a sloping reef and wall known for its colossal sponge formations. Dense clusters of giant barrel sponges, floppy elephant ear sponges, and tube sponges dominate the coral structure, providing habitat for a wide array of macro critters and reef-dwelling fish. Currents sweeping past the reef bring plankton that fuels both benthic filter feeders and swirling aggregations of baitfish.

Rising sharply from an open sandy seafloor offshore from Bootless Bay near Port Moresby, Suzie's Bommie is an isolated coral pinnacle. The reef structure reaches toward the surface and is swathed in dense gorgonian fans, barrel sponges, and soft coral blooms. Because of its freestanding position in open water, pelagic fish school around the upper crest while macro critters shelter within the seafloor crevices and sea fans.

Situated along the northern coast of Milne Bay Province, Wahoo Point is characterized by a reef plateau that abruptly plunges into an oceanic abyss. The point acts as a natural aggregation zone where incoming currents funnel nutrients, attracting large pelagic predators from deep open water while sustaining dense hard and soft coral colonies on the upper terrace.
