BBC News Published image captionThe man and child stayed behind while their companions made the walk for help A father and his 10-year-old son have been rescued in the Australian outback after their three travelling companions walked for 12 hours to seek help. They were driving through north-west Queensland on Sunday, when their car got stuck on flooded roads. Trapped, the group spent the night in the car, and the next morning, three of them headed to the nearest large town, Mount Isa, about 50km (31 miles) west. A rescue mission was launched after the group made it to the police station.
