In major towns and cities in Port Moresby, car rental is possible. The four major car rental companies are Hertz, Avis, Budget and Thrifty. Smaller towns have local rental companies. Depending on the size of the car one intends to hire the cost will vary. In PNG, you will find that on top of the basic rental fee, there is a per kilometre charge. Your valid drivers license is acceptable for up to three months.
Some smaller domestic centres have car rentals but do not have credit card facilities and because of this substantial deposit fees are charged. Payment must be in PNG Kina cash only. The amount of deposits vary depending on the car size and the destination.
