UPDATE: A 14-year-old motorcyclist who spent the night lost in bush near Toodyay was attempting to walk the 30km home in searing heat when he was found.

There were tears of joy from the Blake Burke’s family when the young trail biker was found alive after 23 hours lost in the Julimar State Forest about noon.

Motorists had found the youngster walking near Great Northern Highway, when he flagged them down.

Blake said his bike broke down yesterday about 1pm before he started to walk through the bush.

He found water in a vacant house and slept on a hill before trying to make his way home.

He told reporters he was “relieved” to be found after temperatures reached the high 30s yesterday.

“It was hot...I was sweating like hell just then,” he said.

Police started a search yesterday afternoon and found his bike at 6pm.

His father said the family was grateful to the emergency crews who had worked through to find his son.

“Thank Christ it’s over with, he’s a tough little f----r,” he said.

“Everybody’s put in a top effort and we’ve got a good result, that’s all I can say, thank Christ.

“I can’t thank everyone enough, bloody awesome.”

Blake is being assessed by St John Ambulance paramedics.
