Mount Giluwe is the second highest mountain in Papua New Guinea at 4367m . 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 2km away at 4300m. Giluwe has the distinction of being the highest volcano on the Australian continent, and is thus one of the Volcanic Seven Summits.
