A 5-year-old boy and his 7-year-old brother were admitted to an Australian hospital after surviving with their father for 10 days in a remote national park.

The trio found themselves with little food, no cellphone reception and temperatures that rose to about 38 Celsius (100 Fahrenheit) after dad Steven Van Lonkhuyzen took a wrong turn during a family road trip and got bogged in mud.

They were rescued after farmer Tom Wagner went searching for them Sunday and found them in the Expedition National Park. Wagner says the boys were famished and mighty pleased to see him.

Queensland Police Acting Superintendent Mick Bianchi says Van Lonkhuyzen had planned to drive from his home in Brisbane to Cairns using an inland route when he took a wrong turn and got stuck.
