Mount Giluwe is the second highest mountain in Papua New Guinea at 4,367 metres (14,327 ft), and the fifth highest peak on the island of New Guinea. It is located in the Southern Highlands province and is an old shield volcano with vast alpine grasslands. Ancient volcanic plugs form its two summits, with the central peak the highest and an east peak about 2 kilometres (1.2 mi) away at 4,300 m (14,108 ft). Giluwe has the distinction of being the highest volcano on the Australian continent and Oceania, and is thus one of the Volcanic Seven Summits.

The Volcanic Seven Summits are the highest volcanoes on each of the seven continents, just as the Seven Summits are the highest peaks on each of the seven continents. Two of the Volcanic Seven Summits are also on the Seven Summits list. Kilimanjaro and Mount Elbrus, which were formed volcanically, are the highest peaks of their respective continents.
