Dennis Dear was riding his quad bike with his father in Flint, about 80km southeast of Perth, at 9.30am (WST) on Sunday when he disappeared.
Police had been concerned Dennis would be exposed to the 40 degree temperature and it was believed he didn’t have any water with him.
His quad bike was found on Sunday night and he was found on Monday morning.
Police say a helicopter is taking Dennis to hospital for a check-up and they described him as being relatively well.
State Emergency Service volunteers, police, officers from the mounted section and the police helicopter were involved in the search.
