A BALLARAT man has died after a road trip in New South Wales outback turned to tragedy.
Brian Gadd, 33, was found dead in a waterhole about 150 kilometres from Broken Hill after the car he was travelling left the road.
He was travelling with two other people, a man and a woman, who both survived the crash on Tuesday.
The 24-year-old woman woman walked 20 kilometres to raise the alarm on Tuesday to let police know of the incident.
They found her yesterday morning some distance from the vehicle.
Mr Gadd was found soon after in the waterhole.
The other 21-year-old man, who is yet to be identified, was found in a different area and was treated for heat exposure by paramedics.
Barrier Local Area Commander Superintendent Brad Hodder said Mr Gadd's companions were still recovering.
Police hope to speak with them about the incident later today.
"It is understandable that they have gone through an ordeal throughout the last two days in conditions that would be described as arid and desolate. In some places the grass is around a metre high," he said.
Superintendent Hodder said people in similar situations should not separate and stay with their vehicle.
"If you do become stranded then please stay with your vehicle, have appropriate clothing and water in the vehicle and do not separate.
"It is also recommended you let people know where you are going and expected times that you will be away."
