What beach Nat ?
Without sounding condescending are you good at reading a beach and finding the gutters and channels etc, as this has a major bearing on whether you will catch Jew. Also the tailor you catch arent overly big use the whole fish live as bait or else have a crack at catching beach worms as they are a killer bait for jew but u will need a few.
If you are into smoked fish that is one way people do salmon , but im sure others will have plenty of options.
Keep trying and the illusive mulloway will happen.
Good luck
