Basics would be radio and fishfinder,if budget is tight a small handheld GPS would be a handy addition,but if youve got good land feature you could work off landmarks for a while so it's not a must.On the Nth Coast NSW a 27meg radio will be fine,ch 88 for loging on and off as well as emergencies,and one or two up from that for talking to your mates,I fished with a Nth Coast club for years and only three of us had VHF,I doubt you will be getting out of range in your new rig,with the fish finder get the best you can afford,it's amazing how many people spend heaps on a boat to get to the fish and then scrimp on the very thing that can make the difference between success and failure,so if your going to buy any new gear or toys better to put the money towards a sounder in my opinion and fish with a handline for a while,otherwise I would be looking for the most pixels I could get in a 300 to 350 watt sounder as a minimum for the close reefs.
