Hey mate,
Where abouts in Port Stephens are you.
If i were you i would fish onshore aswell near Jimmy's Beach for flatties,bream and whiting.
Myall river for bream, whiting,flathead,tailor and jewfish too name a few. If you are on the south side then Nelson Bay break wall is great for jewies and bream.
Offshore Broughton Island is the go. If you can get yourself a labeled map then try a few of these spots.
Cod Rock: Mulloway and Kingfish on fresh or live bait.
Coal Shaft Bay: usually a calm water bay with Flathead, Whiting, Snapper and a few kingfish around.
North Rock: Snapper and Kingfish with a few bream and drummer present at times around the washes.
Other offshore reefs from Port Stephens that are good are:
Outer Boulders: Kingfish and Snapper.
Tommy's: Mixed Reef fish eg: Snapper, teraglin, silver trevally and Morwong.
The Sisters: Snapper, Bream, Tailor and Tarwhine near broughton.
Once you tell me where you are based i can give u a heep more info. especially onshore.
