Gecko,
When I was putting back on the trailer a local told me that at the jetty next to the ramp is the place to jig for bait. Heaps there apparently. I will give this jetty a go before I head to the mouth next time.
However.....Next time I will also be trying plastic as well, we will see what happens I suppose.
If you are keen I will send you a note next time I am heading, you can hook up if ya like.
Cheers
Trent
