"The pilot and two passengers were injured in the incident. The helicopter was travelling in tandem with a second helicopter which immediately set down and assisted the injured," the statement said.
"The pilot and a passenger on the second helicopter are caring for the injured until additional medical support can be flown to the area and a recovery operation mounted."
Rescuers were last night hoping a weather window would assist with the recovery of those on board.
A Basler aircraft left Davis station yesterday afternoon looking for viable landing areas for a Twin Otter aircraft which it is hoped can establish a suitable staging point to begin the transfer of the injured to Davis station, the organisation stated.
Reports from the incident site were that all crew members were warm, sheltered and being closely monitored. Communication was being maintained with Davis station.
"At this stage it is not known what caused the incident to the helicopter, operated by Helicopter Resources, and chartered by the Australian Antarctic Division."
