Antarctic authorities were hoping weather conditions on Monday evening would allow an aircraft to recover three Australians injured in a helicopter emergency landing.
A plane left Australia's Davis station on Monday afternoon to look for a suitable spot for a small Twin Otter aircraft to land.
"The Australian Antarctic Division (AAD) is hoping a weather window in the next few hours will allow further positioning of aircraft to assist with the recovery," an Australian Antarctic Division statement said.
The pilot and two passengers were injured when the chopper landed 150 nautical miles from Davis station early on Sunday night.
They were returning from a mission to survey a penguin colony near the Amery ice shelf.
"The helicopter was travelling in tandem with a second helicopter which immediately set down and assisted the injured," the AAD said.
The pilot and passenger on the second helicopter were caring for the injured until additional medical support could be flown into the area and a recovery operation mounted, the division said.
"Because of the nature of the incident and the environment their injuries are being treated as serious and awaiting further medical assessment," the statement said.
"Reports from the incident site are that all are warm and safe and that communication is being maintained with Davis station."
An AAD spokeswoman told AAP: "Everyone's warm, everybody's well attended to, there's a field training officer who's got extensive wilderness first aid skills down there so they are very well attended to."
It is still not known what the problem was with the helicopter, which was operated for the division by Helicopter Resources.
