Three Australian Antarctic expeditioners injured in a helicopter crash have been evacuated from a remote ice shelf in a successful rescue mission.

The victims were conscious and stable, and undergoing medical assessment at Australia's Davis station far south-west of Perth, the director of the Antarctic Division, Tony Fleming, said on Tuesday.

"It's a great result," Dr Fleming said. "We took advantage of a small weather window and its succeeded."

The three were injured when their Eurocopter Squirrel crashed on the Amery Ice Shelf as they returned from surveying a penguin colony late on Sunday. A second helicopter flying with them landed, and rendered first aid while the rescue was mounted.

Crevassing prevented a fixed wing aircraft Twin Otter carrying a medical crew from landing on the ice shelf near the crash site, Dr Fleming said.

But a reconnaissance plane located a clear site on Sansom Island, about 90 kilometres away, and the second helicopter ferried the injured there before all returned to Davis, another 220km away, late on Monday night.

The names of the injured have not been released, and a decision is yet to be made on whether they will be evacuated from Antarctica.

The crashed helicopter is not recoverable, according to Dr Fleming.

"It's in a few pieces," he said.
