I did a mountain bike camping trip down the Wolgan from Newness a couple of weeks ago. Quite a magical trip. We were setting up camp just on sunset and there was an incredibly loud thunderclap as a huge section of the cliff broke off and fell into the valley. The chances of anything like that happening while climbing are probably very small but it does happen. A fellow was killed at Newport I think it was, a couple of years back when the rock he was standing on broke away.
