Mate, having just left Perth for the clear waters off Karratha, the best advice I can give would be the (outer groyne) at Freo Harbour, forget the bait, and take a few small 5 gram metal slices to throw out.  Cast as far as you can out, let them sink just off the bottom roughly and then crank them back with some short pauses.  If there are herring or Tailor around, this beats stinky old bait anytime.  See how you go, you can pretty much try this method anywhere with a bit of depth, burley may help if you can get it past the wind.  Also try the groyne at Cottosloe Beach. Guys are allways gettin Herring, skippy and the occasional Chopper....good luck!
