Unfortunately, out here Phil we don't get Atlantic Cod, which is a shame because it looks great. We do have other delicious fish and the recommended substitute is one called Blue-eye Trevalla (blue eye cod) which is a deep water species. Just as unfortunate though is the difficulty we have obtaining our own best resources, not to mention the cost, so even if you can find it you might expect to pay Aus $60 / kg. I'm always happy to settle for beer battered Flathead. We have Chateau de Cardboard box for about $5 / litre though.
