German backpacker Carolina Wilga, recently rescued, has posted a photo on social media of herself in a hospital, surrounded by food and gifts, as she recovers after being lost in the Western Australia outback for 12 days.

In her latest social media update, the 26-year-old shared that she had lost an astonishing 12kg during her ordeal in the Wheatbelt region, located over 300km north-east of Perth.

“When you need to gain 12 kilograms back,” she captioned a photo, where she is seen sitting on a hospital bed holding flowers, with a large selection of baked goods, tea, and snacks beside her.

She then shared another photo of the treats with the caption, “Thanks to the German consulate!”

“I am certain that I survived only thanks to this incredible outpouring of support,” she said.

“I am deeply impressed by the courage, helpfulness, and warmth that has been shown to me here.

“Thank you Australia – you are amazing.”

Henley described Wilga as “thin and fragile” when she found her.

”I pulled over and got out and gave her a hug,” Henley said.

“She was crying. It was pretty emotional… everybody would be fragile, you know.”

Yesterday Wilga revealed she abandoned her van because she hit her head significantly in a crash and left her car in a state of confusion.

Wilga said she survived by drinking from puddles and sleeping in caves, and walked west in the hope of coming across a person or road.

Having walked at least 14km, Wilga was exhausted, dehydrated and ravaged by mosquitoes when she was found, and also had an injured foot.

She was airlifted to the Fiona Stanley Hospital in Perth, where she is recovering.
