Papua New Guinea’s physical landscape is as dramatic as it is diverse, spanning rugged mountain ranges, vast river systems, and a coastline teeming with marine life.

  1. Papua New Guinea (PNG) occupies the eastern half of the island of New Guinea, the second-largest island in the world, and is located in the southwestern Pacific Ocean just north of Australia.
  2. The capital city is Port Moresby, located on the southeastern coast of the mainland, and it is the largest city in the country with an estimated population of approximately 400,000 people.
  3. Papua New Guinea is part of the Pacific Ring of Fire and experiences frequent volcanic activity and earthquakes; the country has at least 14 active volcanoes, including Tavurvur near Rabaul, which erupted dramatically in 1994 and buried much of the town in ash.
  4. The Sepik River, stretching approximately 1,126 kilometers (700 miles), is one of the longest rivers in the Asia-Pacific region and serves as a vital artery for transportation and trade for communities living along its banks.

Papua New Guinea is a global biodiversity hotspot, sheltering some of the planet’s rarest and most spectacular wildlife within its ancient rainforests and coral-rich seas.

  1. Papua New Guinea is home to the Coral Triangle, one of the most biodiverse marine ecosystems on the planet, making its coastal waters a world-renowned destination for scuba divers and marine biologists.
  2. The country contains some of the world’s last remaining pristine tropical rainforests, covering approximately 70% of its land area, and these forests are among the most biologically rich tropical forests on Earth.
  3. Papua New Guinea is one of the few places in the world where birds of paradise are found in the wild; the country is home to around 38 of the approximately 42 known species of these spectacularly plumed birds, though exact counts vary by taxonomic authority.
  4. Papua New Guinea is home to the tree kangaroo, a remarkable marsupial that has adapted to life in the rainforest canopy; several species are found exclusively on the island of New Guinea and are considered vulnerable or endangered due to habitat loss and hunting.

Papua New Guinea History

Papua New Guinea’s history spans tens of thousands of years of indigenous settlement, a dramatic colonial era, fierce World War II battles, and a relatively recent path to independence.

  1. The country gained independence from Australian administration on September 16, 1975, making it one of the more recently independent nations in the Pacific region.
  2. The Highlands region of Papua New Guinea was largely unknown to the outside world until 1933, when Australian gold prospectors Michael Leahy and his brothers flew over the area and discovered that approximately one million people were living in the fertile mountain valleys.
  3. The Kokoda Track, a 96-kilometer mountain trail through the Owen Stanley Range, was the site of a brutal World War II campaign in 1942 between Australian and Japanese forces, and today it is a significant pilgrimage route for Australians honoring their military history — much like Australia itself holds deep ties to this chapter of Pacific history.
  4. Cannibalism was historically practiced by certain tribes in Papua New Guinea, and the country gained international medical attention in the 1950s when scientists discovered kuru, a fatal prion disease spread through ritual consumption of human brain tissue among the Fore people of the Eastern Highlands.
  5. Australian-born scientist Daniel Carleton Gajdusek won the 1976 Nobel Prize in Physiology or Medicine for his research into kuru disease conducted among Papua New Guinea’s Fore people, which ultimately contributed to the understanding of prion diseases including Creutzfeldt-Jakob disease.

  5. The Asaro Mudmen, from the Eastern Highlands Province, are one of Papua New Guinea’s most iconic cultural groups, known for wearing large clay masks and covering their bodies in gray mud during traditional ceremonies, a practice rooted in a legend about frightening enemy tribes by appearing as spirits from the river.
