Damo, if your coming to the coast from Canberra, then fishing Tuross (which is a bluddy top spot..there are some horse flathead in the lake), you have some of the best options for shallow lake eastuary fishing in the country for what you are targetting. From Ulladulla and Conjola to the north of where you hit the coast road, down through Burrill Lake, Lake Tabourie, Bawley Point (brilliant rock and beach fishing), Durras, Batemans Bay, Broulee and Moruya, Tuross (which you already know) then on to the daddy of them all Narooma - Wagonga inlet.
Offshore in a 13' tinny down there is NOT a good idea, the Batemans Bay area would be the safest bet, but the offhsore fish you are wanting to chase often come into the inlet at Narooma, and there are some major ooglies just upstream from the fishing club in the deep holes.....it is also the home of some GINORMOUS dusky flathead.
For a bit of help ......look up the Canberra Fishermans Club www.canberrafishos.com , most of their members fish in the area you are talking about, not a bad bunch either last time I went to one of their events.
Cheers
