thumb|220x220px|Bus stuck on its way from Mount Hagen to Madang Transport in Papua New Guinea is mainly based around roads (the vast majority of which is unpaved) and air travel. It is in many cases heavily limited by the mountainous terrain and copious amount of rainfall and frequent severe weather occurring in many locations, such as Lae. The capital, Port Moresby, is not linked by road to any of the other major towns and many highland villages can only be reached by light aircraft or on foot.
