The 30-year-old man notified emergency services via his own mobile phone after the accident just before midday.

Tasmania Police search and rescue Inspector Darren Hopkins said it took about 15 search and rescue personnel four hours to reach and stabilise him so he could be extracted from the scene.

The man fell into a crevice while climbing on the north- west side of the mountain and was stuck there for more than six hours.

"This was a complex rescue given the nature of the terrain and the injuries sustained," Inspector Hopkins said last night.

"He was given pain relief and stabilised before being flown out by the Westpac Police Rescue Helicopter."

The helicopter arrived at the Launceston General Hospital after 8.30pm.

Inspector Hopkins said the outcome could have potentially been much worse if the man's mobile phone had been unable to get a signal.

"He's very lucky," he said.

"It's timely that we remind people that if they're going on a walk or climb alone in remote areas, it's integral they let someone know exactly where they're going and at what time to raise the alarm if they don't return."

Inspector Hopkins said mobile phones were unable to get signals in many remote locations and recommended climbers carried personal distress beacons, such as an EPIRB.

"In this case if the phone hadn't worked, it could have been a long time before we found him," he said.
