In reply to Stevo81:
Taped some high- vis strips over the bottom bolts on the affected routes yesterday to discourage/warn folks. Abject failure - 2 of the routes were being climbed when I walked out (including Fun in the Sun which was been top-roped directing through the bolts). Warned them off but reckon it needs better solution asap given the popularity of those routes amongst those new to outdoor climbing.
I can probably go back next weekend with some duck tape to properly tape over any of the clipstick-able bolts to prevent anyone climbing it until it can be made safe (Unless anyone else can do that earlier).
Looking at where the rock has fallen from looks like there's still a couple of tones of loose stuff at the top, and as rtwcharlie noted: the right hand bolt on the lower off on Fun in the Sun has a crack running behind it, so needs replacing. I can do some trundling, but I'm only comfortable bolting with expansion bolts, so it would be good if someone else could fix/move the lower off with glue-ins.
