It offers access to some of the most unspoiled dive sites in the world, with spectacular wall dives, mesmerising reefs and World War II wrecks shrouded in coral. The nutrient-rich waters also foster a diversity of sea grasses, mangroves and algae that comprise critical marine habitats and the black sand muck diving here is second to none.
Whether diving in the calm, nutrient-rich waters off New Britain Island or drifting over coral cathedrals off remote Kavieng, the underwater experiences here are blissfully uncrowded.

Kimbe Bay
Located on the northern coast of mountainous New Britain, Kimbe Bay opens its protected waters to reveal a spectacular underwater world that draws scuba divers from across the globe. This enormous bay, fringed by steaming jungle and looming volcanoes, offers access to some of the most biodiverse waters in the South Pacific region.
At the heart of Kimbe Bay lies a sprawling reef system, boasting over 400 documented species of coral and a kaleidoscope of reef fish in every shape and colour imaginable. Schools of barracuda and trevally hunt alongside hawksbill turtles, while reef sharks patrol the outer reef slopes that plunge into the deep blue abyss. Closer to shore, shallow fringing reefs teem with life, from swaying sea fans to technicolor nudibranchs.
Beyond the main bay, intrepid divers can explore the Witu Islands, a cluster of ancient, eroded volcanic peaks rising abruptly from the sea. Lush coral growth cloaks these underwater pinnacles, which attract large pelagics like mackerel, tuna and even whale sharks. With more than 40 dive sites to choose from, it's no wonder Kimbe Bay has earned its reputation as a world-class scuba destination and one of the best places to dive in Papua New Guinea.

Milne Bay
On the southeastern tip of Papua New Guinea’s main island is Milne Bay, a biodiverse marine area that offers an incredible array of underwater sights. The main draw for divers is the wreck of a B-17 bomber called the “BlackJack”, a World War II-era aircraft that was ditched in shallow waters after it ran low on fuel during a bombing run. Amazingly, the intact plane settled upright on the sandy bottom in less than 30 metres (100 feet) of water, making it accessible to divers of all skill levels.
Over the decades, corals and sponges have enveloped the plane, transforming it into a stunning artificial reef teeming with life. Schools of snapper, trevally and barracuda swarm the exterior while grey reef sharks and wobbegongs laze about within. Many divers consider the "BlackJack" the premier aircraft wreck dive not just in Papua New Guinea, but the entire world.
Not only that but Milne Bay offers some of the world’s best muck diving. Blue ribbon eels snake through tiny holes, while cockatoo waspfish and manta shrimps camouflage themselves in the sand. Octopuses, cuttlefish, pipefish and nudibranchs of every colour and shape can be found by patient divers focused on the little things. Milne Bay truly has something for everyone.

With a plethora of shipwrecks peppered across the seafloor surrounding the island, Kavieng offers wreck diving at its finest. Divers can explore the eerie remains of sunken World War II-era fighter planes, merchant ships and submarines that now provide an artificial reef for vibrant marine life.
The Bismarck Sea side of New Ireland also boasts spectacular reef diving, with the opportunity to get up close to a huge diversity of tropical fish, sea turtles and giant clams. The pristine coral reefs provide a habitat for sea fans and sponges in a rainbow of hues, as well as leaf scorpionfish and pygmy seahorses hidden amongst the coral branches. Additionally, large pelagic species like manta rays, whale sharks, marlin and tuna migrate through the area year-round.
Kavieng’s most famous dive site is undoubtedly Albatross Passage. Here, strong currents funnel through the channel between New Ireland and Aua Island, creating a thrilling drift dive.

Best places to dive in Papua New Guinea
Rabaul
On the eastern tip of New Britain Island, Rabaul and the Duke of York Islands offer a glimpse into the volcanic forces that shaped this region over thousands of years. At the heart of Rabaul lies Simpson Harbour, a tranquil inlet formed from the flooded caldera of a massive volcano.
During World War II, Japan transformed Rabaul into a major military base, fortifying the natural defences of the harbour and volcanic rim. By 1942, the port was a hive of activity as Japanese ships streamed in with troops and supplies. Allied forces launched repeated bombing raids to neutralise the threat, sending over 50 vessels to the bottom of Simpson Harbour.
While some of the wrecks became obscured over time by volcanic ash and sediment, at least 10 are still known and explored by divers today - transporters, freighters and warships stopped forever in their tracks. Rabaul is a must-visit destination for divers interested in PNG’s wartime past and those who can’t get enough of wreck diving.

Tufi
Tufi is a hidden gem positioned at the very tip of Cape Nelson in Oro Province. Surrounded by majestic fjord landscapes, it has earned the nickname “Scandinavia of the Tropics.” Unlike the icy glacial fjords of Norway, Tufi’s breathtaking rias were formed long ago by the ancient eruptions of three nearby volcanoes. The scenery here is simply sublime!
The lack of current movement in the rias has allowed corals to thrive and created a diverse “critter heaven.” Sponges, anemones, sea fans and hard corals cover the sloping walls while schools of tiny fish like mandarin fish, ghost pipefish and pygmy seahorses move between the branches. The diversity here is mesmerising, making Tufi a paradise for underwater photographers and critter seekers alike.
Dotting the coastline are tiny villages, each providing a peaceful backdrop for visitors to relax in between dive adventures. The area has become renowned for its production of tapa cloth, made from paper mulberry tree bark and decorated with traditional designs. For those seeking a more active experience, sea kayaking along the silent fjords allows you to glide across the water while admiring the stunning vistas around every bend.

Schools of butterflyfish flit amongst the corals while angelfish and damselfish dart in and out of crevices.
While reef sharks prowl the area, the real marvels here are the epaulette sharks - strange little creatures that propel themselves along the bottom on their pectoral fins. With their unique locomotion and limited home range, these sharks have evolved over millennia to thrive in the reefs of Madang. For divers, encountering one is a truly memorable experience and a highlight of scuba diving here.
