A man and woman have been rescued after surviving two weeks in Australia’s arid outback on little more than vodka, groundwater and biscuits, but a third person is still missing, police said Tuesday.

Police said Tuesday that a local rancher had found the man, 40-year-old Phu Tran, “slightly disorientated” but in a “good condition” a two-day walk from the vehicle.

His discovery came after Tamra McBeath-Riley, 52, was found on Sunday less than two kilometres from the same vehicle suffering from dehydration.

The three friends set out to explore the country’s vast sun-baked interior near Alice Springs on November 19 when their car became bogged down in a river bed.

After three days staying put and waiting for a rescue, the group feared supplies were dwindling and two of them decided to walk along a property fence line in the hope of finding help.

McBeath-Riley told public broadcaster ABC that the trio accompanied by their blue Staffordshire terrier Raya had survived by drinking pre-mixed vodka drinks and water from a hole dug for cattle, eating biscuits and sheltering in a hole dug under her car.

“She was still fine when he left but we obviously are now focusing our search to identify where she is,” police superintendent Pauline Vicary said.
