Most anglers who say plastics do not work for them are fishing the wrong weight. The lure is rarely the problem — the sink rate and the hook gape are.
Weight is depth control
Choose weight so the plastic reaches bottom in roughly a five to eight second count. Faster and you skip the strike zone; slower and current sweeps you off the structure.
Typical Australian starting points: 1/16–1/8 oz on shallow flats, 1/6–1/4 oz for estuary channels, 3/8–1/2 oz for deeper bay work and 3/4–1 oz plus for offshore reef.
Change weight before you change plastics. Nine times in ten it is the fix.
Hook size and gape
Match the hook to the plastic, not the fish. A 3-inch minnow runs best on a 1/0, a 4-inch paddle tail on a 2/0–3/0 and a 5–7 inch jerk shad on a 4/0–6/0.
Too small a gape buries the point in the plastic and you drop fish. Too large a hook kills the tail action and the bites stop.
Rigging straight
Lay the jig head against the plastic and mark the exit point before you thread it. Ten seconds of care prevents a spinning lure.
The plastic should seat firmly against the collar with no compression bends along the body.
Tie with a non-slip loop knot. It frees the head to swing and visibly improves the fall.
Retrieves that convert
Hop and pause is the default: two sharp lifts, then let it fall on a semi-slack line. Most bites happen on the drop.
Slow roll for cold water and shallow flats. Just fast enough to feel the tail thumping.
Dead stick in cold or pressured water — cast, sink, and do nothing for ten seconds. It is remarkably effective on winter bream and flathead.
Key takeaways
- ▸Set weight by sink rate, aiming for a five to eight second count to bottom.
- ▸Match hook size to plastic length for correct action.
- ▸A crooked plastic will not get eaten — rig it straight.
- ▸Fish the fall: most bites arrive on a semi-slack line.
