Lincoln, and a world-renown Australian adventurer and writer, who scaled Everest in 1984, died “peacefully” in a Sydney hospital, aged 56.

The mountaineer was best known for his miraculous survival after he collapsed near the summit of Mt Everest on May 25, 2006, suffering altitude sickness.

Sherpas attempted to rescue him, but they had to retreat to their camp, and Hall was assumed dead.

However, incredibly, he was found alive by another team, after 12 hours exposed on the mountainside.

The ordeal earned him notoriety. He featured in several documentaries and was inspired to write the book, Dead Lucky.

UK climber Myles Osborne, described how he came across Hall alone at Everest.

“Sitting to our left, about two feet from a 10,000 foot drop, was a man.

“Not dead, not sleeping, but sitting cross-legged, in the process of changing his shirt.

“‘I imagine you’re surprised to see me here,’ he said.

“Now, this was a moment of total disbelief to us all. Here was a gentleman, apparently lucid, who had spent the night without oxygen at 8600m, without proper equipment and barely clothed. And alive.”

Hall, who lived in the Blue Mountains, was a founding director of the Australian Himalayan Foundation.

His lawyers have released a statement saying the mountaineer contracted mesothelioma after helping his father build cubby houses from asbestos cement sheets in the 1960s.

The law firm, Maurice Blackburn, recently concluded a claim for compensation.

Hall’s friend and Himalayan Foundation chairman Simon Balderstone says he is devastated by the loss.

“There were very few tougher, better climbers in the world, and very few better people,” he said.

“Frankly, I’m grief stricken. He was a dear friend and a simply wonderful human being and a wonderful humanitarian.

“I guess I finally have to admit he wasn’t invincible.”

In 1987 Mr Hall was awarded the Medal of the Order of Australia for his services to mountaineering.

Hall is survived by his wife and sons.
