Alright this is completely based on location. Here are my favourite for each place. Places like Sydney harbour are good when you use pilchards, my pb bream at 45cm was on a full pilchard. At boat ramps prawns are great, throw some out and then chuck yours in there. When you are on the flats yabbies are great, keep the nipper on there to try and scare off little pickers. When fishing rockwalls yabbies are my go to bait. When you fish from your boat in deeper water I find chicken to be the best. If you can't get fresh bait just use prawns. One thing that I found interesting was I was fishing some shallow water with bread for mullet when a 35cm bream came up and ate by bread. Don't worry if you don't have fresh bait everything works ok.
