Hey Les,
Your talking more abouts landbased spinning and for your kind of tackle really the more feasible options are flatties, jewies and kingies.
You'd be looking at fishing retaining walls, rockwalls and wharves around the harbour been Sydney based.
Jighead wise try to keep your jigheads as light as possible 9 grams in my opinion is a bit to heavy if your fishing land based. Personally I like the TT jigheads that have the weight towards the middle of the jighead as it allows the lure to sink horizontally. (Very similar in theory to the Nitro Torpedo jigheads unfortunately you don't get them in the 2/0 plus sizes...)
Lure wise your looking at 4 to 6 inch lures shad type lures. The ones mentioned like the jerkshad, gulp 4 inch minnows, larger bass minnows etc are ideal.
As far as metals go you can't go any thing with in your rod casting range should be fine. With metal lures I've never found one better then the other its more about matching the size of your lure to what the fish are feeding on.
Hope this help
