Practical tips for mixing full body, shell, and silhouette decoys

Walk into any game licence office in regional New South Wales or Victoria and you will hear shooters debating how to make a spread look like a real flock rather than a row of plastic trophies. The chat always drifts toward the same three options: full bodies, shells, and silhouettes. Each does a different job on the water, in stubble, or along a dryland feed, with its own weight, cost, and setup time.

A mixed decoy rig recreates a working flock at a glance. Real birds cluster, leave gaps, feed at different angles, and post sentries, and a spread that mirrors that pattern pulls incoming flocks closer and slows their approach. The notes below cover how the three main categories behave, how to slot them together for ducks, geese, and turkeys, and a few Aussie field habits for tricky conditions.

What each decoy type brings to the spread

Full body decoys are the heavyweight option. They show a bird standing, feeding, or resting, with painted feather detail, real-looking heads, and weighted keels that hold them upright in chop. They cost the most, take the longest to deploy, and pack bulky. Their payoff is real shape close to the blind, where incoming birds get a final check before committing, so most shooters set six to twelve in the landing zone rather than across the whole spread.

Shell decoys are the workhorse. They are rigid plastic, moulded in a profile that reads as a real bird from the side, and they sit low on the water or in short grass. Shells handle weather, take knocks from a dog or boot, and stack neatly in a carry crate. They fill out a working waterfowl spread because they show shape from a distance, letting you build a big flock without hauling a hundred full bodies.

Silhouette decoys are the lightest and flattest. They are printed shapes on thin plastic, foam, or fabric, mounted on a short wire stake. From a passing bird's eye they read as a clear body outline against sky or stubble, which is exactly what you need for dryland geese, turkey hunting, or a quick water spread when the lagoon is shallow and shells would tip over. Sillosocks and classic wire-frame silhouettes fold flat in a shoulder bag and go out in minutes.

Starting the spread with a silhouette layer

The base of any mixed rig benefits from flat shapes that read as a flock from far out. Silhouettes fill that role cheaply and quickly, and they let you push the spread wider than you could with shells alone. On a wind-swept stubble paddock in the Wimmera or a fallow block outside Gunnedah, silhouettes give geese the impression of a much bigger gathering without weighing down the ute tray.

For turkey hunters running ranch-raised birds in places like the Hunter Valley or the Southern Highlands, silhouette hens and jakes pair with a full body strutter to break up the outline. A lone tom reads as a trap to educated birds, but a spread of two or three silhouettes behind him suggests a flock and pulls toms into range. The same idea works for puddle ducks: a ring of silhouettes adds numbers and movement without taking up space a shell would fill.

Set silhouettes first because they mark the shape of the spread and pack flat for transport. Use them on the outer edge, where incoming birds first key on the flock. Stagger their angles so half face into the wind, a quarter face crosswind, and the rest feed or rest in random postures. That randomness sells the spread, since real flocks never sit in tidy rows.

Building the middle of the spread with shells

Once the silhouette outline is in, the middle takes shell decoys. Shells give three-dimensional shape and bridge the gap between flat silhouettes and the realistic full bodies in the kill zone. A working number for a duck pass in the southern states is thirty to sixty shells, mixed across two or three species, with a dozen silhouettes ringing the edges.

Shells handle the rig work because they sit on weighted keels, jigs, or self-righting bases tuned for depth and wind. On flooded rice stubble near Coleambally or a shallow lignum swamp, low-profile shells ride the chop. On deeper water like the Western Treatment Plant ponds or Lake George, add keel weights so decoys sit properly. Quick clips and swivels make it fast to add a drag weight when the wind swings around.

Mixing species in the shell layer matters in Australia. A flock of all Pacific Blacks looks staged, while a mix of Pacific Black, Grey Teal, and the occasional Mountain Duck reads as a real working mob. Sprinkle a few Chestnut Teal into the run for the drakes on brackish estuaries, and add a couple of Pink-eared shells on a claypan. Birds commit harder when the spread matches what they see overhead.

Anchoring the kill zone with full bodies

The last decoys to go out are full bodies, and the rule is less is more. Full bodies cost the most, take the longest to position, and create the visual weight that pulls birds the final few metres. Twelve full bodies around the blind will do more than forty strung across the lagoon, because close-in birds judge the spread by the densest cluster first.

Place full bodies where birds will set their feet. For ducks, that is the edge of the decoys nearest the blind or the downwind pocket where birds want to touch down. For geese on a dryland feed, the kill zone is often a gap in the silhouette outline where birds have a clear path to land. A handful of full bodies in that gap, plus one or two sentries with heads up, finishes the deception.

Use full bodies to fix the angle of the spread. Set the full body landing pocket so it stays in place even if you adjust the shells around it. Sentry decoys looking downwind tell incoming geese the flock is relaxed. Pair full bodies with motion units if your state allows them, but keep the motion off until birds are committed.

Matching the mix to Aussie species and seasons

Australian game bird seasons vary by state, and so does the species mix on the water. In Victoria the duck season traditionally opens around the second Saturday of March and runs through June, with Pacific Black Duck, Grey Teal, Chestnut Teal, Hardhead, Pink-eared Duck, and Mountain Duck on the bag. South Australia and New South Wales run similar windows, while Tasmania focuses on local black duck. Each species responds differently, which shapes the decoy mix.

Mountain Duck like wide, open water and a strong silhouette outline, so they respond to a shell-heavy spread with silhouettes on the outer edge. Pink-eared Duck and Grey Teal feed in loose mobs over shallow claypans, and a wide spread of mostly silhouettes and shells outperforms a tight cluster of full bodies. Chestnut Teal hold close to brackish edges and saltmarsh, so a few full bodies tucked into reeds with shells fanning out tends to work on coastal lagoons like the Coorong.

A typical Cape Barren spread leans on silhouettes and shells because the birds are cautious and feed on pasture. A handful of full body decoys near the blind gives the final close-in detail once they swing in. Match the decoy mix to what you see in the district before opening morning, because local birds get wise to over-staged spreads.

Spacing, wind, and rig tricks on Aussie waters

Wind is the single biggest variable in any spread, and how it behaves on Aussie lagoons can catch out shooters used to bigger water. A stiff southerly on Lake Tyrell stacks birds into a tight corner, so pack the downwind edge with decoys and leave the upwind side open. A light easterly on a coastal estuary spreads birds out and lets you run a wide, even rig. Set the silhouette outline first.

Spacing on water should run two to three body lengths apart for ducks and four to six feet for geese. Birds read gaps, and a spread with even spacing looks staged. Cluster pairs tight, leave a gap, then start another small group, and finish with a few singles feeding on the edge. That pattern mimics the way Pacific Blacks and Grey Teal actually raft up.

Run cord through the keel on a slight angle so the decoy rides the wind naturally. Quick-release clips and small swivels mean you can pull a line in seconds if a bird tangles the spread. Keep drag weights in the kit for sudden gusts that flip shells on shallow water. A repair kit with cable ties, paracord, and spare swivels sorts most field problems without cutting a hunt short.

Transport, storage, and keeping gear working

Full bodies pack into dedicated carry bags with head slots that stop paint rubbing off and heads from snapping. Shells stack in a milk crate with pads to stop them cracking on rough station tracks. Silhouettes go flat in a single bag, which is one of the reasons they earn a spot in the kit even when the rest of the rig is built around shells.

Clean gear before it goes back in the ute. Mud from a Bool Lagoon hide dries hard and scratches paint, and salt from a tidal flat near Corner Inlet chews through cheap swivels in a season. A quick rinse, a dry in the shed, and a light spray of silicone on moving parts keeps hinges and clips working. Check keels for cracks, look over rigging cord for fraying, and replace any crimp that has started to slip.

Storage in the off-season matters as much as field care. Decoys in a hot tin shed in Mildura or a damp garage in Hobart fail in different ways: heat warps thin plastic silhouettes, damp grows mould on flocked heads and rots fabric socks. A cool, dry spot out of direct sun is the cheapest insurance. Crimp new cords each year, repaint faded full bodies with a touch-up kit, and weigh down loose shells. Gear that comes out ready to rig saves swearing on opening morning.

The right mix of decoys depends on the species, the season, and the water, but the principle holds every time: layer the spread so it reads as a real flock from a distance, then fills out close up.
