Just south of culburra is jervis bay and there are heaps of landbased fishing there including the tubes, mermaids inlet and almost every beach around here is worth giving a shot. When fishing the tubes you will need quality tackle, you can catch some very big kings off here. Salmon and bonito are also possible with all of your standard rock fish, but for kings I would probably use livies, but normal bait can work. there is also another beach Steamers beach but is on the south side of jervis bay, so it would take around an hour to get there but fishes great. It is a top spot fo salmon, tailor and fishes well for species like bream, whiting, kingfish, but im not sure about jewies or bonito. PM me if you need anymore help and I want to see a report on it.
