William Callaghan, 14, was lost in the harsh Victorian bushland for two freezing nights but has survived the incredibly 250km journey “relatively unscathed”.

He is expected to leave hospital early this morning and was treated for a few cuts and abrasions in hospital after being found by a volunteer yesterday.

He went missing on Monday afternoon after walking away from family members at Victoria’s Mount Disappointment.

Incredibly, he managed to avoid hypothermia despite spending two nights in the freezing bushland.

“Probably because he’s an active young man,” Dr Joanne Grindlay, the deputy director of Victoria’s Royal Children’s hospital, told the  ABC.

“Children are often a lot more resilient than us adults.”

Emergency registrar Dani Bersin told the  Herald Sun  Will was “looking pretty good”.

“It is quite incredible to survive the elements in the cold,” she said.

“He has come up relatively unscathed, from the cold. It is a fantastic result.”

Will’s mum, Penny Callaghan, revealed his first request after being reunited with his friends and family.

He wanted McDonalds, which Penny explained “I think he wanted hot salty food”.

She said that he communicated that he was “confused and scared”.

“He keeps pressing the body, saying his body feels weird,” she said.

“I can’t imagine what he’s been feeling and going through. I am just so relieved.”

Penny also thanked the community and volunteers for their efforts in helping find Will in the bushland.

“More than anything thank you, everyone, I’m so grateful, you’re all amazing. What an amazing community,” she said.

“I want to be with my boy. I couldn’t believe it [when he was found], I can’t imagine what he’s been feeling and going through.

“I’m just so grateful and so relieved, he’s just a very special person.

“All the people in his life just love him to bits.”
