Kavieng, at the northern tip of New Ireland Province in Papua New Guinea, is tide-driven channel diving: incoming Pacific water funnels through the passages between New Ireland and New Hanover, drawing grey reef sharks, dogtooth tuna, rays and schooling pelagics onto current-swept walls. WWII aircraft wrecks and the scuttled Der Yang long-liner round out a remote Coral Triangle destination served by two small dive operations.

Description
Kavieng sits where the Bismarck Sea meets the open Pacific, and its diving runs on the tide: up to six tidal exchanges a day push water through the maze of islands and passages between New Ireland and New Hanover, so the best dives are timed to the incoming tide, when visibility jumps past 30 m and the current switches on the fish action. The signature site is Albatross Passage, a terraced channel wall southwest of town where grey reef sharks, dogtooth tuna, barracuda, eagle rays and mobulas work the current above gorgonian- and black-coral-covered ledges. The Pacific side adds wrecks: the Der Yang, a seized Taiwanese long-liner scuttled in 1988 beside the Echuca Patch ridge, and a cluster of WWII aircraft including the 'Deep Pete', a remarkably intact Mitsubishi F1M floatplane on white sand at 40 m off Nusa Lik Island. Between channel dives there are gentle coral gardens, resort house reefs and harbour muck diving with frogfish, pipefish and the occasional mimic octopus. Water stays 28–30°C year-round; August–October brings the calmest seas, with April–June and September–November the most reliable windows overall. It is a remote, low-volume destination — a domestic flight from Port Moresby — best suited to divers comfortable with current.
Highlights
What makes this dive worth the trip.
Albatross Passage is Kavieng's signature dive: a terraced channel wall near Cape Masala where, on the incoming tide, grey reef sharks cruise the blue alongside big dogtooth tuna, schooling barracuda, and mobula and eagle rays over gorgonian fans and black coral trees.
The Pacific side of Kavieng holds six WWII aircraft wrecks, including remnants of a RAAF PBY Catalina flying boat and the 'Deep Pete' — a Japanese Mitsubishi F1M floatplane discovered in 2004, resting remarkably intact on white sand in 40 m off Nusa Lik Island.
The Der Yang, a Taiwanese long-line fishing boat seized in the late 1970s and deliberately sunk in 1988 as a warning to illegal fishers, lies on its side in about 30 m beside the Echuca Patch ridge, swept by clear Pacific water and circled by the same pelagics it once hunted.

Albatross Passage
Kavieng's signature dive — the first passage between mainland New Ireland and the New Hanover island chain, ending at Cape Masala. A terraced wall starts on an upper terrace around 10 m and steps down past a sandy plateau at about 30 m, covered in big gorgonian fans, black coral trees and sponges. On the incoming tide the blue fills with grey reef sharks, dogtooth tuna, schooling barracuda, jacks, and mobula and eagle rays, while the wall itself hides nudibranchs, leaf scorpionfish and pygmy seahorses.

Echuca Patch & the Der Yang
A large sausage-shaped open-ocean ridge just outside Kavieng on the Pacific side, rising from white sand at about 44 m to within 10 m of the surface, its top covered in pillar corals and anemones. Trevally, reef sharks, yellowfin tuna, mackerel and circling barracuda are regulars. The Der Yang — a seized long-line fishing boat scuttled in 1988 — lies on its starboard side in about 30 m on the edge of the ridge.

Deep Pete
A Japanese Mitsubishi F1M ('Pete') reconnaissance floatplane from WWII, discovered in April 2004 on flat white sand in 40 m off the western side of Nusa Lik (Small Nusa) Island. Though the tail is broken, the biplane shape is remarkably intact for such a lightweight aircraft. A resident school of yellow sweetlips streams around the wings, with batfish and barracuda patrolling the blue above.

Bottle Shop
A shallow muck dive under the pier in Kavieng Harbour, less than 10 m deep over a sandy, debris-strewn bottom. Decades of harbour junk shelter classic critters — frogfish, pipefish, nudibranchs and other macro subjects — making it a favourite between channel dives.

Lissenung Island House Reef
The house reef wrapping about two-thirds of Lissenung Island, a small resort island roughly 20 minutes by boat southwest of Kavieng. Shallow (2–10 m) and credited with around 350 fish species, it is a photographer's and night-diving favourite: seahorses, six species of clownfish, cockatoo waspfish and crocodilefish all live here, and green and hawksbill turtles nest on the surrounding beaches.
