Papua New Guinea (PNG) is one of the last truly wild frontiers on Earth. Covering the eastern half of the world's second-largest island plus over 600 offshore islands, PNG contains some of the most extreme biodiversity on the planet — most of it barely catalogued. Scientists believe thousands of species remain undiscovered in its highland forests. For wildlife travelers, PNG is the ultimate destination.
Birds of Paradise
PNG is the global epicenter of the birds of paradise — 38 of the world's 43 species are found here. These are among the most spectacular birds on Earth, with elaborate plumage displays evolved through millions of years of sexual selection. Males perform extraordinary courtship dances — some hanging upside down from branches, others inflating iridescent breast shields, others clearing and decorating forest stages.
Key species and where to see them:
- Raggiana Bird of Paradise (national symbol) — Eastern Highlands and Tari Valley. Displays at dawn from treetop leks.
- Greater Bird of Paradise — Aru Islands and lowland forests. Golden plumes cascading from the flanks.
- King of Saxony — Highland forests. Two bizarre head wires extending twice the body length.
- Wilson's Bird of Paradise — Waigeo Island (Raja Ampat). Blue skin cap, spiraling tail, and a cleared dirt stage.
Birdwatching lodges in the Highlands (Ambua Lodge, Kumul Lodge) cater specifically to birders, with local guides who know every display tree.
Marine Biodiversity
PNG's coral reefs sit within the Coral Triangle — the global epicenter of marine biodiversity. The reefs around Milne Bay, Kimbe Bay, and the Bismarck Sea harbor:
- Over 2,000 species of reef fish
- 600+ species of hard coral — more than the Great Barrier Reef
- Manta rays, whale sharks, hammerheads, and huge schools of barracuda
- WWII wrecks integrated into reef ecosystems
Diving in PNG is world-class — rivaling Indonesia's Raja Ampat for sheer species density. Liveaboard dive boats operate from Madang, Kavieng, and Milne Bay.
Unique Mammals
- Tree kangaroos: PNG has 10 species of tree kangaroo — marsupials that evolved to live in the forest canopy. The Matschie's tree kangaroo is stunning — golden-brown with a face like a teddy bear.
- Echidnas: The long-beaked echidna — one of only five surviving monotremes (egg-laying mammals) — lives in PNG's highland forests.
- Cuscus: Large marsupials with prehensile tails found across the islands.
- Flying foxes: Massive fruit bats with wingspans over 1 meter.
Rainforest — The Third Largest on Earth
PNG contains the world's third-largest tropical rainforest (after the Amazon and Congo), covering about 70% of the country. Much of it is unexplored. The rainforest stores massive amounts of carbon and harbors unknown species — new frogs, insects, and plants are still being described annually. The Kokoda Track (a 96 km WWII trail through the Owen Stanley Range) passes through spectacular primary rainforest.
Practical Information
- Getting there: Air Niugini flies from Singapore, Manila, Tokyo, Cairns, Brisbane, and Sydney to Port Moresby.
- Safety: PNG requires planning. Port Moresby and some urban areas have security concerns — use trusted transport and accommodation. Rural and marine areas are generally safe with a local guide.
- Costs: PNG is expensive due to logistics. Expect $200–$400/day for guided nature experiences. Liveaboard diving runs $350–$500/day all-inclusive.
- When to go: May–November (dry season) for highlands and birdwatching. Diving is year-round.
Papua New Guinea is not a comfortable destination — it's a wild one. But for wildlife enthusiasts, divers, and adventurers willing to embrace the challenge, it offers encounters that exist nowhere else on the planet.
