An Australian expeditioner injured in Antarctica remains in a serious but stable condition.

The man sustained multiple fractures during an accident on Monday evening (October 20) after an accident while riding a quad bike near Davis station.

He received medical treatment at the scene and was transported back to the station by Hägglunds overland vehicle.

He continues to receive round-the-clock medical care by the station doctor and lay medical team, in consultation with medical officers at the Australian Antarctic Division.

Another doctor is on board the Australian Antarctic research and resupply ship Aurora Australis which is heading towards Davis station and is currently about 800 nautical miles away.

The Australian Antarctic Division (AAD) continues to investigate all options for the expeditioner’s evacuation to specialist medical care in Australia.

The man was due to return to Australia in mid-November after a 12-month stint in Antarctica.
