Lihir Island is the largest island in the Lihir group of islands, 22 km long and 14.5 km wide, in Papua New Guinea's New Ireland Province. It consists of a complex of several overlapping basaltic stratovolcanoes rising 700m above sea level. While the volcanoes are not currently active, geothermal activity is still present.

Flights to Lihir Island with Air Niugini

The Island is located 900 km NE of Port Moresby. Annual rainfall averages 4800mm per annum, temperature ranges between 19 and 35 degrees Celsius. The population of the Lihir Group is around 18,000.

The economic focal point of the Island is the Lihir Gold Mine. The mine is operated by Lihir Gold Limited. The mine holds one of the world's largest gold resources (40 million ounces).The mine is located on a geothermically active area and to enable the mine to proceed, holes have been drilled into the ground to release subterranean pressure. These gases have been, in part, captured and are used to operate a 56MW geothermal power station which generates 75% of the mine's power requirements.

The largest settlement on the Island is Londolovit, where most of the expatriate mine employees live. Basic shopping and health care facilities are located here. The local hospital has inpatient and outpatient facilities and provides health care services to both the expatriate and local communities.

An airstrip large enough to land a small jet is also located north of Londolovit, at Kunaye.
