Australian police find body believed to be of missing hiker

It's believed the body of a missing woman in the Northern Territory has been found.

Search and rescue officers were focussing on the Palmer Valley Station area today and NT Police announced that they had located a body at 1:00pm.

Tran was found on Tuesday in the area of the Palmer Valley by pastoralist Ted Fogarty.

Ms Hockridge, her partner, Tamra McBeath-Riley, 52, and South Australian man Phu Tran, 40, went missing after going for an afternoon trek on Tuesday, November 19.

On Wednesday morning, police inspected tracks they believed belonged to Ms Hockridge.

The three friends had set out to explore the country's vast interior near Alice Springs on Nov 19 when their vehicle became bogged down in a river bed.

But events took a dire turn when the vehicle bogged down in the bed of Finke River, leaving the group stranded.

Claire Hockridge and McBeath-Riley were living in Alice Springs and had been showing local landmarks to Tran, who was visiting Alice Springs from the south coast city of Adelaide.

After a week of staying close to their auto and waiting for discovery, Tran and Hockridge set off on foot to find shelter and water, while McBeath-Riley stayed near the vehicle with their dog, Raya, she told reporters in a press conference after her rescue.

Mr Tran told Mr Fogarty he had left Ms Hockridge behind to look for help.

"We are all grieving and exhausted from the emotional roller coaster that we've ridden", Sarah Hockridge told reporters.

Teagan posted on social media: "Devastated & heartbroken doesn't reach our pain in this time; we as a family appreciate the public's respect for our time of grief & while we come to terms with this reality".

Ms Hockridge, 46, was in a group of three people who became stranded in the central Australian outback a fortnight ago.

Formal identification is yet to be conducted and police will prepare a report for the coroner.

Ms Hockridge's partner, Ms McBeath-Riley, was found at a waterhole east of the Stuarts Well area, south of Alice Springs, late on Sunday December 1.

For a few days, the group stayed close to the auto, surviving on the limited supplies they had packed, McBeath-Riley said.

They left a note inside their auto.

Food and water sources are scant in Australia's remote desert outback, and temperatures regularly exceed 40C (104F) during the day.

Ms McBeath-Riley spoke outside hospital on Monday, saying she was "worried to death", because she thought the pair - who had a Global Positioning System and compass with them - would have earlier reached the Stuart Highway.
