German tourist Carolina Wilga was found alive in Australia's remote Outback on Friday, 12 days after she went missing and a day after her abandoned van was discovered, police said.

  The last known sighting of the 26-year-old backpacker, and the last day family and friends heard from her, was June 29. She was seen at a general store in the wheat farming town of Beacon, 320 kilometres northeast of the Western Australia state capital Perth. Beacon had a population of 123 during the 2021 census.

A member of the public found Wilga wandering on a forest trail late Friday, Western Australia Police Force Insp. Martin Glynn said.

She was in a "fragile" state but had no serious injuries and was flown to a hospital in Perth for treatment, Glynn told reporters.

"I think once we do hear her story, it will be a remarkable story," Glynn said, adding it was a "great result" for the backpacker's family and those involved in the search.

"You know, she's obviously coped in some amazing conditions," he said.
