Fishing is hit or miss depending on Mother Nature. Schoolies should be abound on the Island by then. Do yourself a favor and buy some squid jigs. Jig up some squid for bait and for the table. If your not catching fish on the plugs don't be afraid to baitfish and save the trip because we all know they want the bait not the plugs this time anyway.
AO - send me a PM when you are in the neighborhood - would like to meet you and go fishing. You are usually too far away for any of the site's get togethers ...
