The trip is roughly 114km, or a five-hour drive on the Jarra Jarra Access Rd.
The bodies of a young family - a 19-year-old man, a 19-year-old woman and a three-year-old boy - were found yesterday about 4.5 kilometres from their broken-down vehicle.
The teenage parents left morsels of food and water at their abandoned auto and attempted to find help in a community 18km away.
An extensive land and air search is now underway for a 12-year-old who is believed to have been a passenger in the vehicle, after police received information from other family members.
They never made it that far.
Supt Nobbs said the man who initially raised the alarm at Willowra Health Clinic would be a critical part of the police investigation.
Police are still continuing precautionary land and air searches to rule out anyone else being stranded in the Outback, according to The NT News.
Police said the deaths were not being treated as suspicious.

Because of flooding rain and the remoteness of the area, police investigators took a few hours to reach the vehicle.
"The whereabouts of this boy are not known at this time", Superintendent Jody Nobbs told reporters on Thursday.
"Although police have no information that suggests there were other passengers in the vehicle, we will continue a precautionary land and air search until we are satisfied that all areas of interest have been sufficiently canvassed", Southern Desert Division Superintendent Jody Nobbs said.
It is believed the group may have died from exposure after leaving their broken down vehicle and not in a auto crash as was initially reported.
Mr Gill said the two adults and child may have died several days ago.
Family members have not authorised the release of the boy's name but say people living in the surrounding communities of Ali Curung, Ti Tree and Willowra are aware of his identity.
"This does serve as a timely reminder to anybody travelling on the Northern Territory roads, when you do travel, your vehicle is in a fit state for travel", Superintendent Nobbs said.
