Dusky Flathead — Estuary ambush predator — NSW's most-targeted sport fish. Also called Lizard, Dusky, Flatty.
The 70 cm maximum legal size on dusky flathead in NSW is not a concession to anglers — it is a conservation line. Almost every fish over that mark is a breeding female. The slot limit only works if the released crocodiles actually live.
Dusky Flathead is also known as: Lizard, Dusky, Flatty. Estuary ambush predator — NSW's most-targeted sport fish.

Drift sandy banks and weed-edges in 1–3 m, casting plastics ahead of the boat and hopping them back with sharp two-rod-lift jerks then long pauses — flathead inhale on the drop. Lock onto the edges where sand meets weed or mud meets channel; they sit camouflaged in the sand waiting to ambush. In rivers, target tide-fed flats during the run-out as bait gets funnelled off the banks. Big "crocodile" females (70 cm+) are almost always released — they're the breeders.
Field-proven Dusky Flathead methods compiled from published tackle guides — AU East estuaries, bays, flats, drains and surf gutters. Every method links its source.
1soft plastics on the drift
Bait / lure: 3-4in paddle tail, grub, worm, curl-tail, prawn or minnow-profile plastic
Rig: light-medium spin outfit with 1/12-1/4oz jigheads in about 2/0-3/0, adjusted for current and depth; rig plastic straight
When & where: sand flats, drop-offs, drains and channels; keep the lure close to bottom while drifting or walking to cover ground
2slow-rolling plastics near bottom
Bait / lure: curl-tail or paddle-tail soft plastic
Rig: spin outfit with jighead heavy enough to contact bottom, then slow-roll a foot or two above bottom
When & where: estuary edges and flats where flathead are lying in ambush; simple slow continuous retrieve is a beginner-friendly producer
3trolling hardbodies
Bait / lure: small bibbed hardbody that occasionally bumps sand or mud
Rig: light trolling spin/baitcast outfit; set lure depth so it runs on or near bottom
When & where: shallow estuary water, channel edges and sand flats where covering ground finds active fish
4live-baiting for larger fish
Bait / lure: legal-size live baitfish
Rig: 4-8kg rod, baitfeeder-style reel, 15-20lb leader about 1m long, medium ball sinker above a swivel and a single circle hook sized to bait
When & where: deeper holes, drop-offs, drains and edges where larger dusky flathead wait for prey
Last two hours of the run-out and the first push of the run-in is the prime window. Slack low and high are dead. On strong spring tides, fish the back-eddies and bank edges — they ambush bait being pushed past them in the current.
Flathead are not strongly moon-dependent. Light level matters more — overcast days fish better than bluebird days, and the bite often turns on in the last hour before dark regardless of moon phase. Spring tides do push more bait around, which indirectly helps.
Figures come from each jurisdiction's own fisheries authority, with the source linked on every page above. Rules change — closures in particular are reset annually — so confirm with the authority before you keep a fish.
Dusky flathead carry a slot limit in several states — an upper size as well as a lower one — so the biggest fish is protected rather than prized. The slot exists because dusky flathead 60 cm and over are virtually all breeding females, and releasing them is what keeps an estuary producing. The per-jurisdiction figures are above; check them before you measure a fish.
