Australian Geographic Travel’s new five-day expedition takes eight birders to Boigu Island, Australia’s northernmost inhabited island, in search of species more often seen in New Guinea.
On Boigu Island, the view to the north isn’t open ocean. It’s Papua New Guinea, just 6 km across the water. In fact, some of the birds in Boigu’s ancient mangroves have more in common with that coastline than with anything on the Australian mainland.
Australian Geographic Travel has launched Birds of the Borders: Boigu Island Expedition, a five-day, four-night birdwatching trip (departing Cairns in April and October 2027) to this remote setting, Australia’s northernmost inhabited island, marooned in the heart of the Torres Strait.
A Papuan Bird List on Australian Soil
Boigu is low and wet. Its 89.6 square kilometres of freshwater swamp, mangrove and samphire wetland rise no more than 18 metres above sea level. That habitat, and the island’s position on New Guinea’s doorstep, is what makes its species list so unusual. In fact, several target birds reach the edge of their range here on this remote atoll, and are actually recorded far more often in New Guinea than in Australian waters.
The wish list reads like a field guide to the wrong country. It includes the Papuan hornbill, red-capped flowerpecker, orange-fronted fruit-dove, collared imperial pigeon, Gurney’s eagle and Papuan spine-tailed swift. The magnificent riflebird, palm cockatoo and eclectus parrot are on it too, while guests will need to keep a sharp eye out for Great-billed heron, mangrove robin, little kingfisher, black-necked stork and migratory shorebirds.
Birding on Island Time
The trip has been developed with input from the island’s Malu Kiai Rangers, while a Boigu Indigenous coordinator joins every session to give cultural briefings and share local knowledge. Sessions follow the tides rather than a fixed timetable, which says a lot about who the itinerary is built around.
There are eight guided sessions in all. They cover village-edge habitat, creeks at dawn, mangrove channels, freshwater wetland and the northern coastline facing Papua New Guinea. Groups are capped at eight guests to ensure absolute intimacy with nature.
Community life is also part of the trip. Guests receive a Welcome to Country on arrival, and mid-tour, they will join community members for a traditional fishing session, which is optional but included in the price. The final evening ends with a traditional feast, island dancing and storytelling in the native Kalau Kawau Ya language.
Getting There
Getting to Boigu takes two flights, a Qantas hop from Cairns to Horn Island, then a private charter on to Boigu. On the island, guests stay in community-run accommodation with all meals, birding sessions and cultural experiences included. Travel insurance, gratuities and accommodation in Cairns before and after the tour are not included.
For birders who have already seen the mainland’s northern specialities, this is a rare chance to add Papuan species without leaving Australia, in the company of the people who know the island best.
