Commonwealth Bay Region Cruises

Commonwealth Bay is an open bay about 48 km (30 miles) wide at the entrance between Point Alden and Cape Gray on the Adelie Coast of Antarctica. It was discovered in 1912 by the Australasian Antarctic Expedition under Douglas Mawson, who established the main base of the expedition at Cape Denison at the head of the bay. It was named after the Commonwealth of Australia. It is listed in both the Guinness Book of World Records and the Eighth Edition National Geographic Atlas as the windiest place on Earth with winds regularly exceeding 150 miles per hour. Mawson's Huts at Cape Denison still exist and are currently being conserved by the AAP Mawson's Huts Foundation.
