Paul, are you bringing your boat? You will be able to launch off the beach at Minni Water without too much drama.
I don't have any waypoints for there, but I do recall catching stacks (mainly snapper) about 20 minutes wide of Minni Water a few years ago, not much would have changed.
Good whiting and flathead in the creek at Wolli, also a place not far from there called Jerusulem Creek......not sure of the spelling, has a healthy population of Australian bass.
Will pm you when I find out more.
