Hey kaneo,
Im in the Campbelltown area aswell. If im not in the boat i usually head down the coast but yeah dont stop at windang lol can only properly be fished from land 2 hours either side of the high and low.
My suggestions would be port kembla, shellharbour/bass point, Wollongong. There is a few wharf and places to fish in these areas that would probably suit you. Jump on google and see what you can find.
Hope this helps ✌
