Papua New Guinea's Main Sea Port: Port Moresby

Port Moresby is the capital, largest city, and primary international seaport of Papua New Guinea. Located on the southeastern coast of the mainland (Papua) on the Gulf of Papua, it handles the vast majority of the country's maritime trade, including exports of minerals, coffee, palm oil, and LNG, and imports of fuel, machinery, and consumer goods.

Other notable ports include Lae (second largest, on Huon Gulf), Madang, Kimbe, and Rabaul, but Port Moresby is the principal gateway.
