He was gone two weeks.
Gaskell, an Australian hiker who went missing in Malaysia's Mulu National Park, is believed to have survived by eating berries, bananas and wild fruit, according to CNN affiliate Sky News Australia.
A search and rescue team found Gaskell alive at about 1 p.m. local time Tuesday, Fire Chief Law Poh Kiong told CNN.
Law called it a miracle.
Gaskell was covered in leeches and disoriented, according to Sky News.
He was "quite weak," but was able to eat some tidbits of food, Law said.
"I don't think he had taken food for almost 10 days," Law said.
Dr. Jack Wong, the director of Miri Hospital where Gaskell was treated, said he is "quite stable," though he sustained some minor injuries.
Wong expects the Australian to recover in a few days.
"He never let's anything phase him, not like the average person. He's very, very mentally strong," his friend Mitchell Carnes told Sky News. "I think that's probably what's pulled him through today."
Nearly 70 people had been searching for Gaskell, 25, for about six days.
"The area where he was going hiking does not have had good mobile coverage so his family was expecting to have difficulties contacting him," Gaskell's family told Tasmania Police.
