Somewhere like the Sydney Fish Markets everyone buys the best and the best is consistent. Everyone buys the best snapper and the best prawns. It also depends what's running at the moment so in kingfish season they will be everywhere. You just have to get comfortable with one of the vendors, make one of them your pal and the more serious they think you are about it the better fish they are going to try to give you.
Josh Niland, head chef at Australian seafood restaurant Saint Peter, loves fish. But he also appreciates that cooking seafood is a bit of a dark art, so we joined him on a walk through the Sydney Fish Market where he gave us the low down on what to buy, when to buy it and what to look for when you want the freshest seafood in Sydney.
