Why is air travel important for transportation within Papua New Guinea?

Air travel is essential in Papua New Guinea because the country lacks a comprehensive, reliable road network. The nation has no railroads and very few paved roads, leaving many regions isolated from major population centers like Port Moresby.1

The existing road infrastructure, such as the Okuk (Highlands) Highway, is frequently compromised by landslides, inadequate maintenance, and damage from heavy rainfall. Consequently, for areas not served by the limited road network, air transport remains the primary or only viable means of travel between small towns and provincial centers. While the number of small, remote airstrips has declined due to funding constraints and road expansion, aviation remains a critical component of the country's transportation system.1
