Heavy sea ice and deteriorating weather are slowing efforts to get support personnel and supplies from the Australian Antarctic research and resupply ship Aurora Australis, to Davis station, to assist with the evacuation of injured expeditioner Dwayne Rooke.
Based on current weather and ice conditions, the ship is expected to be in helicopter range of the station by Wednesday.
A doctor and lay medical personnel from the ship will then fly to Davis to assist with the medical care of Mr Rooke.
Mr Rooke, 31, of Devonport, Tasmania, sustained multiple fractures after a quad bike accident on Monday 20 October.
He remains in a serious but stable condition under the care of the Davis station doctor and lay medical team, who are trained to assist the doctor in patient care.
The Australian Antarctic Division is continuing to investigate all options to evacuate Mr Rooke to specialist medical care in Australia.
