Mate i stayed in the same park and baited up a good spot. Walking distance from the boat ramp, if you follow the track from the boat ramp on your right, you'll come to an opening with a fallen tree on your left. I fished here for a couple of days, got a few runs, but my gear wasn't good enough for the fish. Check it out, it's worth a try.

ps. sweetcorn as bait.
