Hi Mark, I stopped in Narooma last year for a swim just on the western side of the bridge and saw a heap of whiting hanging around the sand bar there. looked like a hot spot to chuck a few small poppers or wrigglers in on the incoming tide. I was there snorkeling with the kids a keep thinking I wish I had my gear. around the back where all the marinas and jetty's are I saw some guys pumping for nippers so there's some easy bait gathering around. you should be able to get a few bream and ludrick off the board walk and around the break walls I saw heaps of bream but they didn't seem to active. I've never actually fished there so I'm only going off what I would do if I went back. have fun and good luck.
P.S. if you get fish and chips go to the shop opposite the caravan park on the main road. we went there and it was awesome. the shops around the back were no good as our friends told us.
