Craig,
It will depend on the prevailing winds.
It's a bit cold for Awoonga, but you never know...
You could launch at Boyne and fom there you can go out to seal rocks or up the front of facing island if it's not too choppy.
Or you can launch at Toolooa bends and fish the old jetty or stay in the creek for cover.
Or you can launch near the power station and fish calliope creek.
There are endless spots, just be aware that the harbour can chop up badly at times.
good luck
