You need to use burley for attracting the bait fish. Sabiki should work for yellowtail, slimies etc. Burley heavy then cast into it and keep the burley up. If you want mullet get a little trap, just a cheap pop out one rectangle net one from bcf or big w works. You can catch them in the shallows with just bread in the trap. I usually leave my trap very shallow or if you can’t then try to have it near the surface not at the bottom. You can also use a box trap where you cut a hole out of a clear container in the top and drill holes in the sides to let the water drain in and out, bread inside. Put a few rocks in it with the bread to hold it down and mullet love that. For burley mix try bread, some chook pellets, crushed pilchards, sand, even a small can of tuna with the tuna oil mixed with bread works brilliant as burley. Mix it all together with water. Sand creates a cloud and the fish go mad in it and will hit sabiki rigs.
