Two men have died in the Australian Outback after their four-wheel drive vehicle broke down and they ran out of water, less than 10 kilometers (6 miles) from a water supply.

According to Australian Associated Press, police in Western Australia said the bodies of a 42-year-old man and his 21-year-old nephew were found last Friday by a station worker next to their Land Rover on the remote Talawana Track on the edge of the Great Sandy Desert.

They said the men may have died some days earlier. They left the mining town of Newman, in the Pilbara region of Western Australia, on March 28. Temperatures in the area have been above 40 degrees Celsius (104F).

Inspector George Putland, of police communications in Perth, said the men were not well-prepared for their trip, with an old vehicle and little water, AAP reported.

Another police officer, Senior Constable Greg Thomas, told Australian Broadcasting Corp radio that tragically, if the men had a good map they would have known that bore water was available another nine kilometers along the road.

He said the men's vehicle was unsuitable for outback travel in extreme temperatures and that they did not have enough food or water or a two-way radio.
