Australians are queuing up to cruise the world's southernmost continent with demand for bookings stronger than ever.
Passenger numbers for Chimu Adventures to the Antarctic Peninsula have more than doubled since 2008, says Chimu boss Greg Carter, with the upward trend climbing sharply over the past 18 months.
"This is a destination like nowhere else on the planet," he said.
"Untouched by humans, there is no development, the landscapes are ethereal, the wildlife abundant.
"This is one of the most wildly beautiful places to travel in the world and it is back on the bucket list for Australian travellers."
With limited cabins left for the 2015-16 Antarctica cruise season between now and March, Carter says bookings need to be made soon.
