Fly River, River system in Western Province, Papua New Guinea.
The Fly River is a major river system in western Papua New Guinea that flows for over a thousand kilometers through densely forested land. At its mouth, it spreads into a wide delta with several channels where the water reaches the sea.
A British explorer discovered and named this river in 1845 while surveying the coast of the region. The name comes from the ship used during that expedition.
The villages along the river depend on it for daily life: people fish, transport goods, and travel between settlements using small boats and traditional methods. The waterway shapes how communities are organized and connected to each other.
Travel on the river is possible but there are few regular services and infrastructure is limited. If you want to get around by water, you should allow time for boats to arrive and be prepared for basic conditions.
The river ranks among the world's largest waterways when measured by the volume of water flowing to the sea. Nowhere else in the Oceania region does another river carry more water.
