All of the advice here is good stuff and all I can add is if you are landbased, try using blades or bigger plastics to get some distance then target weedy drop off areas in 0.5-2m. If you can, get out onto the flats at a really low tide and look for flathead lies in the sand/mud. If you see a large croc imprint, come back and flick something around there at the first of the run out. Good luck!
