Papua New Guinea has minimal public transport infrastructure with limited bus networks in major urban centers. No metro, subway, or rail transit systems exist. Urban transport relies primarily on informal minibus services with poor integration and limited accessibility. Air transport serves as critical connectivity for remote areas.

PNG has approximately 29,700-30,000 km of roads, with 8,740 km comprising the National Road Network. Much infrastructure remains in poor condition with inadequate maintenance. The Highlands Highway is a critical economic corridor. Mountainous terrain, heavy rainfall, landslides, and earthquakes pose ongoing challenges. The Connect PNG program targets rehabilitation and expansion through 2040.

Papua New Guinea has limited internet infrastructure with low broadband speeds and minimal fiber network deployment. Rural areas face significant connectivity gaps. E-mobility readiness index is low with limited access to supportive technology and financial instruments.

Minimal fiber deployment, concentrated in major urban centers; limited rural connectivity

PNG operates 646 total airports including 21 major airports (large and medium), with Air Niugini as the national carrier supplemented by private operators. Domestic air services connect all major population centers reliably. International connectivity is moderate with limited global hub status. Airports serve as critical infrastructure for remote communities lacking road access.
