An injured man who spent the night trapped down a remove cave in Western Tasmania has been successfully retrieved.
The 62-year-old was caving with friends in the Mount Cripps area near Cradle Mountain yesterday afternoon when he slipped and fell several metres while climbing a ladder.
It's understood the male from Ulverstone had badly injured his back and was unable to return to the surface.
Two friends hiked several hours to get phone reception and raise the alarm, while another stayed back for assistance.
A search and rescue team involving Ambulance Tasmania, Tasmania Police, SES and the Northern Caverneers Caving Club didn't reach the location until about 1am this morning due to the rough terrain.
All rescue equipment had to be carried to the site, which is about one and half hours walk from the nearest road.
At about 8:00 this morning, crews managed to get the man out of the cave and he was taken to the Royal Hobart Hospital via the rescue helicopter, reportedly suffering from mild hypothermia.
"My information is that he's a very experienced caver with a lot of experienced people who were well equipped and did all the right things," Acting Inspector David Chapman said.
