A seriously ill man has begun a two-week ocean voyage on an icebreaker from an Antarctic base to a hospital in Australia.
The Australian Antarctic Division said the man was flown by helicopter in cold and snowy conditions from Davis Station on the coast of Princess Elizabeth Land to the Australian icebreaker Aurora Australis.
It said the icebreaker is expected to reach the southern Australian city of Hobart around April 4.
The authorities have released no personal details about the man, who is a tradesman.
They have not revealed the nature of his medical emergency, other than to describe his condition as "serious but stable".
