Hockeridge, her partner Tamra McBeath-Riley, 52, and her companion, Phu Tran, 40, sat in a 4WD auto stuck in a dry riverbed during a sightseeing cruise on November 19.
Hockridge was last seen by Tran at the Palmer Valley Station fence line two days ago, police said earlier on Wednesday.
During the day, the group dug a hole underneath the auto to stay cool and then slept in the vehicle at night, the Australian Broadcasting Corporation reported.
She was with a group of three that had been missing in the outback since November 19, before her two companions were found.
The group and Ms McBeath-Riley's canine, Raya, had been travelling from Alice Springs to go on a hike after they grew to become bogged within the Hugh River. They believed she would have had little to no water supplies left.
That they had used up all their provides of water, in addition to some vodka drinks, biscuits and beef noodles they'd within the automotive.

Former Pakistani cricketer Rameez Raja has said that in the future Pakistan team should not play Australia cricket. Australia fast bowler Pat Cummins became the first bowler to claim 50 Test wickets in the year 2019.
A local rancher then on Tuesday found 40-year-old man Phu Tran, "slightly disorientated" but in a "good condition" a two-day walk from the vehicle. They noticed Ms McBeath-Riley on Sunday, about 1.5km (0.9 miles) away from the automotive.
'He continued to stroll alongside the fence line for 2 days and approached the pastoralist as we speak and the very first thing he did was get some water'.
"He said he was coming with me", Fogarty told The Australian newspaper.
Ms Hockridge's emotional triplet sisters Sarah and Melinda told reporters it had been a "tremendously hard and agonising time".
Phu Tran, 40, was discovered on Tuesday morning by a pastoralist to the south of Alice Springs.
"Even though Claire has died in awful circumstances, we are glad that Tamra and Phu have been found alive and well, and we're extremely grateful to everyone who's involved in that".
Temperatures reached about 40C in the area while the group was missing.
The daughter of Ms Hockridge, Teagan Eden-Street took to social media to share the heartbreaking loss of her mum.
