Renowned adventurer Sir Douglas Mawson sailed into Commonwealth Bay in January 1912 as part of the Australasian Antarctic Expedition. More than 100 years later, cruise ships have been able to call at this very difficult-to-reach destination. But that wasn't the case for several years when a massive iceberg, measuring 140km long x 50m wide, covered the entrance to the bay.
Named after the Commonwealth of Australia, the site is located between Point Alden and Cape Gray. It is listed in the Guinness Book of World Records as the windiest place on Earth. Winds regularly exceed 240km per hour, particularly in the winter months when storms can be sudden and strong, although summer brings calmer periods.
The extreme weather doesn't keep the wildlife away. The area has become an important breeding site for emperor penguins, Adelie penguins, Antarctic petrels and leopard seals.
