Hey mate,
Try Dangar Island if u want flatties.
I also get flounder, bream, whiting, tailor, small snapper and crabs.
Great spot. U have to be very specific though where you fish. I find the area on the south point of the west side to be best. everywhere else seems pretty ordinary. As you said try wobby for jews:)) Just try the south west point for flatties, whiting, bream, tailor, snapper and crabs with prawns and nippers and your all good. Frozen prawns do the job really well.
