Air travel and interisland shipping are the principal means of transport in the Pacific Islands because they are essential for connecting widely scattered island groups where extensive road networks are limited to only the largest islands.1

These modes of transportation are vital for several reasons:

  • Geographic Connectivity: Due to the fragmented nature of the region, air and sea transport provide the primary links between small towns, remote outstations, and major population centers.12
  • Economic Necessity: Many island nations are net importers of basic materials, such as food and petroleum, making reliable shipping services critical for trade and domestic needs.3
  • Tourism: As a leading economic activity for many islands, tourism relies heavily on the accessibility provided by international airports and cruise ship routes to bring visitors to often secluded or offshore locations.14
  • Infrastructure Challenges: In many areas, such as Papua New Guinea, internal road networks are either nonexistent, poorly maintained, or frequently obstructed by natural events like landslides and heavy rainfall, necessitating air travel for essential movement.2
