The isolated outback station at Palmer Valley, south of Alice Springs, will be the focus of police search efforts today for the remaining missing person, Claire Hockridge.
It is believed the 46-year-old would have run out of water by now.
Police search efforts located footprints in the area late yesterday, which are they are yet to confirm as belonging to the 46-year-old.
Two of the trio missing for almost two weeks in the central Australian outback have now been found alive and well.
Phu Tran was fortunate to be found by the owner of Palmer Valley Station yesterday and Tamra McBeath-Riley, 52 was found on Sunday in the nearby Stuarts Well area.
A focused search of the Palmer Valley Station area continues today with members scouring the area on foot and motorbikes.
"We have a team of experienced officers who will be searching on foot, and on motorbikes in some areas, but working carefully to ensure any signs or tracks left by Claire are not disturbed," Supt Pauline Vicary said.
Ms Hockridge was last seen at the Palmer Valley Station fence line two days earlier by her friend, Phu Tran who was located by a pastoralist conducting bore runs in the area, yesterday morning.
Ms Hockridge has now been missing in remote central Australia for more than two weeks, and it is believed she would have limited to no water supplies by now.
The rescued man says he left his friend two days ago to find help.
Police are concentrating their aerial search on the area, adjacent to the Palmer Valley Station boundary fence, where he last saw her.
Phu Tran was found in the area of Palmer Valley by a pastoralist doing a bore check .
The man is disorientated, thirsty and hungry but otherwise in good condition after being stuck in the outback for two weeks.
The pastoralist said the man was extremely lucky to be alive.
Tamra McBeath-Riley, 52 was found on Sunday after police located the vehicle the trio were travelling in bogged in the dry bed of the Hugh River.
Again it was a pastoralist who led police to the stuck vehicle.
Her two friends had headed off in a different direction, towards the Stuart Highway, after 14 days in the outback, believed to have been walking in a different direction to get help after their car became bogged.
Ms McBeath-Riley was treated for dehydration and exposure but was able to tell media she stayed alive by finding muddy cattle water.
The three had gone four-wheel-driving south of Alice Springs on Tuesday, November 19.
NT police have failed to find them even after an exhaustive search by air and land after they were reported missing on the next Saturday, four days after they were last seen.
Police said Claire Hockridge was "fine" when the man left her at the fence.
