rock fishing is pretty much summed up in "there are old rock fisherman and there are bold rock fisherman. but there are no old, bold rock fisherman".
Honestly, if u have never rock fished before, why drive to avoca to try it out? Try a spot closer to your location and see if its for you..u will lose tackle, and even possibly all your gear when rock fishing, seen it happen plenty of times before. Be prepared to lose fish as line n rocks dont mix, rock boots are essential, never fish alone. Make sure u can swim (sounds stupid but suprisingly alot of rock fisherman cant swim) and always keep one eye on the ocean for incoming sets etc.
Avoca isnt more dangerous than any other exposed rock ledge. Uve just gotta use common and acquired sense.
