I've grown up snorkelling around Pt Turton & have occasionally seen YFW in the shallows, but never in great numbers. I've never caught one when fishing for whiting or mullet from the shore, though I haven't tried with lures on the flats before. I've definitely seen plenty of KGW in <1m of water in the sandy areas around weed & reef edges though, and i'm sure they would put up a great fight on light gear. Good luck!
