How to Use Sinkers and Weights for Better Fishing in Australia
Getting your bait or lure to the right depth is one of the most important skills in fishing — and sinkers and weights are what make it happen. Whether you're chasing bream in shallow estuaries, targeting flathead on the bottom, or dropping for mulloway and snapper in deeper water, the right weight setup puts your presentation exactly where the fish are.
What Do Sinkers and Weights Actually Do?
Sinkers add mass to your rig so your bait sinks to the desired depth and stays there, even in current. The right weight keeps your line taut, improves bite detection, and prevents your presentation from drifting out of the strike zone.
Get the weight wrong — too light and your bait floats up unnaturally, too heavy and it kills the action — and you'll miss fish even when they're feeding.
Types of Sinkers
- Split Shot Sinkers — Small, clamped directly onto the line. Perfect for finesse fishing where you need a little extra depth without affecting lure action.
- Egg Sinkers — Oval-shaped, the line passes through the centre. Ideal for running rigs where you want the fish to feel minimal resistance on the take.
- Ball/Round Sinkers — General purpose, great for still water and light current.
- Bank Sinkers — Elongated and streamlined, best for deeper water and stronger tidal current.
Using Jig Heads as Weighted Hooks
For soft plastic fishing, jig heads are your sinker and hook combined. The weight is built into a lead ball head so your plastic sinks naturally and swims at the right angle on the retrieve.
The Kingdom Lead Head Jig Hook (3.5g–14g) is a great starting point — triple-edge hook point and carbon steel construction handle everything from bream to flathead and mulloway.
If you're running packs, the Meredith Round Ball Jig Head comes in 18 weights from 1g to 22g in 10-packs (light weights) and 5-packs (heavy). The round ball head minimises snags and gives paddle tails and swimbaits a natural swimming action. High-carbon steel with a chemically sharpened point and barbed keeper to hold plastics firm.
Choosing the Right Weight
| Weight | Depth | Conditions | AU Target Species |
|---|---|---|---|
| 1g – 4g | 0–1m | Calm, shallow, slow retrieve | Bream, Whiting (finesse) |
| 5g – 9g | 1–3m | Light current, estuaries | Bream, Bass, Flathead, Trevally |
| 10g – 16g | 3–6m | Moderate current, open water | Flathead, Snapper, Mulloway, Bass |
| 18g – 22g | 6m+ | Deep water, strong tidal current | Barramundi, Mulloway, Kingfish, Snapper |
As a general rule: match heavier weights to deeper water and stronger current. In calm, shallow conditions, go lighter — it lets your bait or plastic move freely and looks more natural to wary fish.
Recommended Line Weights to Match
- 1g–4g jig heads — 2–4lb fluorocarbon leader, 4–6lb braid main line
- 5g–9g jig heads — 4–8lb fluorocarbon leader, 6–10lb braid
- 10g–16g jig heads — 8–12lb fluorocarbon leader, 10–15lb braid
- 18g–22g jig heads — 12–20lb fluorocarbon leader, 15–30lb braid
Using Sinking Lures as an Alternative
If you'd rather not rig soft plastics, sinking hard body lures handle depth naturally without a separate sinker. The Kingdom Heavy Sinking Minnow Lure sinks on a pause and can be worked at any depth with a jerk-and-pause retrieve — deadly on flathead, trevally, and barra.
For a bigger profile in deeper water, the Kingdom Tsunami Soft Bait Lure (170mm, 55g) sinks fast and swims with a natural tail action that draws strikes from serious predators like mulloway and kingfish.
Tools to Set Up Your Rig
Crimping your own leaders and rigs? You'll want a proper set of crimping pliers. The High Carbon Steel Fishing Crimping Pliers handle wire cutting and leader crimping cleanly, making it easy to build solid, reliable rigs at home or on the water.
Final Tips
- Start light, go heavier — always begin with the lightest weight that gets you to depth. Less weight = more natural action = more bites.
- Match weight to current — in a running tide, you'll need more weight to hold bottom. In still water, go as light as you can.
- Feel the bottom — for flathead especially, you want to feel your jig head ticking the sand or weed. If you can't feel bottom, go up a weight.
- Change it up — if you're not getting bites, try a different weight before changing your plastic. Depth and sink rate often matter more than colour.
