Another story from todays ABC
http://www.abc.net.au/news/2014-10-09/q ... ection=qldPolice say they are confident their initial search did not miss a woman who spent 17 days surviving in a far north Queensland rainforest.
Shannon Leah Fraser, 30, emerged scratched up, severely sunburnt and 17 kilograms lighter from the rainforest at Golden Hole, near Innisfail, on Wednesday after she went missing there on September 21.
She was taken to the Innisfail Hospital by a nearby farmer who spotted her.
Ms Fraser, an Innisfail local, had visited the popular hole with her partner three Sundays ago and had followed him for a walk in the rugged terrain but became separated and disorientated, her brother Dylan Fraser told the ABC.
She had survived on river water, small fish and insects during her ordeal.
A hospital spokeswoman said Ms Fraser was recovering well, despite her weight loss and injuries.
On Thursday Inspector Rhys Newton said authorities had searched an area with a radius of several kilometres around the water hole and were confident Ms Fraser had not been anywhere in the search zone.
He said police had only spoken briefly to Ms Fraser and hoped to interview her again when she was released from hospital.
"Can I say the methodologies that are employed in that search operations are tried and proven and extremely sound," he said.
"I am convinced that there was an extremely high probability of locating that missing person had she been in that area that we were searching."
Lone survival is 'more mental than physical'
A Queensland survival expert said beating loneliness and despair would have been as important as a fresh water supply for Ms Fraser in lasting 17 days alone.
"Very few people actually spend more than 24 hours completely alone in their entire lives so doing it for 17 days in an unfamiliar environment is going to be a challenge for anybody," former Australian Defence Force survival instructor Nick Vroomans said.
Mr Vroomans, who now runs the Staying Alive survival school in Laidley, west of Brisbane, said both physical and mental issues came into play.
"And one impacts on the other, but to me as I've developed in my expertise of survival over the years I've realised that more of it's mental than it is physical.
"Some people have survived long periods of time in particularly hostile environments and other people have died when you’d think they should have survived so it's a difficult question to answer."
But he said the human body was capable of great feats of endurance.
It’s not until people find themselves in these situations they realise just how resilient we really are.

"We're all wired for survival every one of us, otherwise we wouldn't be here," he said.
"We are an amazingly adaptable animal and it's not until people find themselves in these situations they realise just how resilient we really are."
Mr Vroomans said having a source of fresh, unpolluted water would have made a huge difference to Ms Fraser.
"It would appear that she never had the ability to light a fire or anything like that, which is quite debilitating," he said.
"If you can light a fire you're halfway home - you can also boil water and make it safe to drink.
"Obviously where she was the water was safe enough to drink and that makes a big difference so you're not going to get sick."
Lack of food not an issue: expert
He said it took a long time for lack of food to become a survival issue.
"As far as food's concerned, she was probably, at 17 days, about halfway to being in a very serious situation," he said.
"She could probably have gone for another couple of weeks and even though she'd be in a pretty bad way she would've been able to survive it.
"As long as she's not working too hard and using too many calories then it's a survivable situation.
"The first three or four days in a survival situation not eating is the worst that I've found.
"After that you tend to start to stabilise ... around about the 10-day mark you're not even hungry anymore."
