To be honest most rock ledges are dangerous and i wouldnt recommend going to ANY rock ledges with out the proper footwear at least! and people who dont have the "minimum" requirements shouldn't be on a rock ledge fishing, i even got taken down at avoca on sunday and i was wearing my spiked rock fishn boots i wouldn't say im inexperienced but one foot off place sent me 3-4 metres backwards and almost lost my rod/reel, it happens a fair bit and lately its been pretty unpredictable at Avoca.
needless to say i pretty much stoped fishing after that as did a few other raiders.
