Brisbane Bushwalkers hiking guide Neil Parker, 54, was at Cabbage Tree Creek when he fell down a 6-metre waterfall.

"It took me an hour to get down there. About 40 minutes to get to the waterfall. And I climbed the waterfall many times before, and this time, with it being so dry and the lime on the rock, instead of sticking, slipped and gave way," Mr Parker said from his hospital bed this morning.

"I caught myself the first time as I started to slide, but I had too much momentum and over I went. I was climbing up, so I started looking down and I started sliding down the face of the rock. And I slid about 20 feet, cartwheeled and slammed into the rock and then landed in the creek on the bottom.

"So straight away, I thought 'I'm now in a lot of trouble because no one knows where I am'.

"I thought, if anyone is going to raise the alarm, I have to scramble back out of the rocks to get out of here.

"I went to put my phone into my pocket and missed and into the drink — now my phone is gone. And I thought, 'the only way to get rescued is self rescue'."

Mr Parker splinted his shattered leg with hiking sticks using his first-aid supplies.

He then began his two-day crawl to a clearing hoping he would be seen by other walkers or a rescue helicopter.

Mr Parker said he was only planning to hike for three hours and had to survive on a handful of nuts, a protein bar and lollies.

"It's the worst possible scenario," he said.

Mr Parker said he spent seven years volunteering for the SES and had been involved in a number of rescues and knew he had to try and crawl to a clearing.

"I had some idea of what they can and can't do and I knew where I was located there was no way they were going to be able to find me," he said.

Queensland Health said Mr Parker lifted his broken leg every step of the way.

Orthopaedic surgeon Dr Nicola Ward said Mr Parker's injuries would have been extremely painful and it was "incredible" he was able to move himself.

"I've never heard any such survival effort with two broken limbs… he's done extremely well," she said.

"Essentially, with an ankle fracture like he's got, the limb is a deadweight and useless, you can't walk on it, you can't put weight through it and you need to drag it and similarly with the wrist," she said.

Dr Ward said it could be months before Mr Parker is able to use his injured leg.

"Ultimately with a fracture like this you can expect eight to 10 weeks of non-weight bearing," she said.

Lucky to be found

Mr Parker said he was "fairly worried" as he had not told anyone where he was going, but he was determined to stay alive for his family.

"First thing I thought was I'm not going to die out here, I'm going to live.

"It's all through what I've been trained to do and what I've learnt — the experience people have given me is pretty much what made the difference I think."

His family set out on Monday to find him with the support of the Brisbane Bushwalkers group.

The group's president, Steve Simpson, said Mr Parker knew the area "intimately" but was concerned as it was rugged bushland.

"He's a very confident, capable and experienced walker and he's learnt survival skills in our club," he said.

"You just never know in those terrains what can happen."

Mr Simpson said he was relieved when Mr Parker was rescued.

"As soon as word got out that he was found and was alive it was a great feeling of celebration," he said.

Rescue crews said Mr Parker was lucky to be found.
