Where would the best place be to buy fresh seafood to throw on the bbq?
The fish market at Kiama Harbour is OK, tho sometimes a little limited in choice (a lot of its stock is from the small local fishing fleet). Very convenient if you just want to wander around and pick up something from what's on offer.
The choice and quality at the fishmonger at Stockland Shellharbour is very good.
If you're into fresh oysters, take a trip down to Greenwall Point (past Nowra, a bit under an hour's drive) and pick up some freshly shucked Crookhaven oysters.
