Australia’s highest mountain is not located on the fifth continent itself, but on remote Heard Island in the Southern Ocean, close to Antarctica. There, a snow-covered and still active volcanic massif rises from the sea to 9,000 feet – like a large white whale. Five attempts to climb the whale hump fail. Then, in the mid-1960s, a bunch of seaworthy and mountain-skilled, fearless and humorous Australians make a new attempt to climb Mawson Peak. On a simple schooner they fight their way through choppy wave crests to the island and indeed reach the summit on the second attempt. The eminent Australian documentary filmmaker Michael Dillon tells the story of this great adventure with original footage and touching memories of the daring men themselves – one even sings them, as befits such an epic saga.
