Mountainous terrain has limited the development of roads in many parts of Papua New Guinea. The capital, Port Moresby, is not linked by road to any of the other major towns and many villages in the highlands can only be reached by light aircraft or on foot.

Where there are roads there are many privately operated Public Motor Vehicles, mostly minivans, which function as unscheduled buses. In coastal locations fibreglass "banana boats" provide the same sort of service.

Most of the transport services which require a larger investment, such as aircraft and long distance ferries, are run by the churches or church affiliated companies, for example Luship (from "Lutheran"), Adventist Airlines (better known as "Sevende") and Missionary Air Services. One notable exception is the government owned Air Nuigini.
