Michael James Leahy MBE was an Australian explorer and gold prospector, famed for his exploration of the Highlands area of Papua New Guinea. He photographed, filmed and published many of his explorations widely.

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.
