Depth first, profile second, colour last
Every Australian lure decision starts with one question: how deep is the fish and how do I get a lure to sit in that band for as long as possible? A 3-inch paddle-tail on a 1/4 oz head and the same plastic on a 1/16 oz head are, functionally, two completely different lures. Owning three jighead weights and two plastic sizes gives you more genuine options than owning twenty plastics and one weight.
Profile comes next. Match the dominant baitfish or crustacean: small prawn and nipper profiles for bream and whiting on the flats, slim baitfish profiles for flathead, tailor and salmon, bulkier profiles for barramundi and mangrove jack, and long slender stickbaits for kingfish and tuna feeding on garfish and pilchards.
Colour matters least, and mostly as contrast. A useful Australian rule: natural and translucent in clear water and bright sun, dark solid profiles in dirty water or low light, and something with UV or chartreuse when there is tannin stain after rain. Two or three colours per profile is genuinely sufficient.
