West New Britain, Papua New Guinea: field notes and photographs of the island

Fire

The fire mountains

Travel along the north coast of West New Britain and the horizon keeps rising into cones. The island sits where two plates of the Earth's crust press together, and that pressure comes up through the ground as volcanoes.

The tallest is Ulawun, one of the most active volcanoes in Papua New Guinea. When it erupted on 26 June 2019, more than 10,000 people moved into care centres within two days; it erupted strongly again in November 2023. Closer to Kimbe stands Pago, a young cone growing inside the old Witori caldera. About 3,300 years ago Witori exploded so violently that ash buried gardens and forest across the whole Willaumez region.

The heat that threatens also gives. It warms the hot springs at Pangalu near Talasea and the bubbling sulphur ponds at Pokili, and it builds the dark, rich soil that feeds gardens and oil palm.

Stone

The glass of Talasea

Long before metal, the sharpest thing in this part of the world was volcanic glass. On the Willaumez Peninsula, around Talasea, eruptions left behind obsidian: black, glossy stone that breaks to an edge finer than a steel blade.

People have come for it for a very long time. Obsidian from Mopir, in West New Britain, has been found in sites on New Ireland dated to around 20,000 years ago, when the sea stood far lower than today. Even then it had to cross open water, by canoe.

Later, Talasea glass travelled astonishing distances. Its chemistry works like a fingerprint, so archaeologists can trace flakes found thousands of kilometres away back to these sources.

Flakes still lie in the gardens near the old sources. Look, and leave them where they are.

Sail

Lapita voyagers

After the great Witori eruption, something new appears in the ground of this region: pottery stamped with fine, toothed patterns of bands, zigzags and faces. Archaeologists call it Lapita.

The people who made it were extraordinary sailors. From the Bismarck Archipelago, of which New Britain is part, their descendants sailed east across open ocean to islands no one had ever lived on: Vanuatu, New Caledonia, Fiji, Tonga and Samoa, in only a few centuries.

They carried pigs, chickens, yams and taro, and the paper mulberry tree, whose bark became the barkcloth of the Pacific. Many people in Polynesia today can trace their ancestry back along this route.

Reef

Kimbe Bay

Kimbe Bay curves for about 140 kilometres between the Willaumez Peninsula and Cape Tokoro. Its reefs rise from water more than 2,000 metres deep, so divers drift along walls of coral with nothing but blue below.

Scientists have counted around 860 kinds of reef fish and 400 kinds of coral here: more than 60 percent of all the coral species of the Indo-Pacific. Sperm whales, orcas, spinner dolphins and dugongs share the bay.

The reefs are looked after by the people who own them. Villages run eight locally managed marine protected areas, which have helped keep dynamite fishing out.

Warmth

Eggs in warm ground

At Pokili, in the Nakanai country, the ground is warm underfoot. Hidden among the trees, the Melanesian megapode, a dark, hen-sized bird with big strong feet, digs deep burrows in the volcanic soil and lays its eggs there.

It never sits on them. The heat of the volcano does the work, and when the chicks hatch they dig their own way up, ready to look after themselves.

Local families collect some of the eggs, and the colony sits inside a wildlife management area so that the harvest can go on. Birdwatchers come for other treasures too: the golden masked owl and the blue-eyed cockatoo, found almost nowhere else.

Cloth

Barkcloth

Across the Pacific, cloth is made not by weaving but by beating. The inner bark of the paper mulberry is stripped, soaked, then pounded on a log with a grooved wooden beater until the fibres spread and knit into a soft sheet.

In West New Britain, the Nakanai people used barkcloth in the ceremonies that honour the dead: to cover funeral masks, and to wrap the bones of relatives before they were kept among the family's wealth. Next door in East New Britain, the Baining build giant barkcloth masks for their night fire dances.

Masks and dances return every year at festivals across the province.

Ancestry

Ancient DNA from Watom

Pots and obsidian show how things travelled. Ancient DNA shows who travelled. In 2025 scientists published the first ancient genomes from Papua New Guinea, including people buried on Watom Island, in the heart of the Lapita world.

The oldest people from Watom carry only Papuan-related ancestry. East Asian-related ancestry appears from about 2,100 years ago, after a delay of centuries: newcomers and local communities did not mix for a long time.

Watom lies off East New Britain, near Rabaul, but it shares the Bismarck Archipelago story of the Willaumez sites. No ancient genomes from West New Britain itself have been published yet.

Celebrate

The Oil Palm Festival

Oil palm built modern West New Britain, and brought families from the Highlands and the Islands to live side by side. Since 2025 the province has celebrated both.

The first Oil Palm Festival of Arts & Culture ended at Kapore on 27 June 2025. In June 2026 about 1,000 visitors came to the Sir John Maneke stadium at Hoskins Station for three days of dances from across Papua New Guinea, mask dances from the peoples of the province, and string bands.

Plantations cover about 90,000 hectares here. The next festival is scheduled for June 2027.

Travel

Getting there

Flights from Port Moresby reach Hoskins in about an hour and a quarter. Kimbe, the provincial capital, is a short drive away on the shore of the bay.

Most visitors come to dive, from resorts on the bay or aboard liveaboard boats, but the island rewards anyone who slows down: hot springs at Pangalu, sulphur ponds at Pokili, forest birds, and sportfishing for dogtooth tuna and blue marlin. At Cape Gloucester, in the far west, Allied troops came ashore on 26 December 1943.

Land and reef belong to local clans. Ask before you walk, fish or photograph, and you will be welcomed.
