Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Estuaries, coastal lakes, sand and mud flats, channel edges and weed beds from north Queensland to Victoria's Gippsland Lakes; Lake Macquarie, Moreton Bay and the Gold Coast Broadwater are famous.
  2. Rig up: 7 ft light-medium spinning rod (2–5 kg). 15–25 lb fluorocarbon β€” flathead have rough mouths and sharp gill spines.
  3. Pick your bait: Live poddy mullet, prawns, whitebait and pilchard pieces. Lures: Soft-plastic minnows and paddle tails hopped along the bottom, vibes and small diving hard-bodies.
  4. Fish it: Drift or walk the edges of sand flats and channel drop-offs on the falling tide, hopping soft plastics along the bottom with long pauses. Look for "lies" β€” flathead-shaped marks in the sand.
  5. Time it: Daylight hours, especially early morning and late afternoon. The first half of the run-out tide, when bait drains off the flats and out of the creeks; the turn of high tide is good too.
Fishing techniques

BigJoe's tip

Big flathead are breeding females; release the "crocs" and keep the 40–60 cm fish for the table.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Clean & cook

Is it good to eat, and how to prepare it.

Edibility

Excellent eating β€” one of the best-tasting fish in its range.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Excellent white, flaky fillets β€” Australia's favorite fish and chips fish. Crumb or batter and fry.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Two sharp, venomous-feeling spines on each side of the head and sharp dorsal spines β€” a jab is very painful. Hold the fish by the lower jaw with a lip grip, and never grab it around the head.

Regulations

Queensland uses a 40–75 cm slot; NSW has a 36 cm minimum and allows only one fish over 70 cm. Check current rules. Each Australian state sets its own rules: NSW and Victoria require a recreational fishing licence in fresh and salt water, Western Australia needs a licence for boat fishing and freshwater angling, Tasmania for inland waters, and Queensland only for stocked impoundments; the Northern Territory needs none. Bag limits, size limits, closed seasons and marine park zones apply everywhere.

Conservation

Keep only what you'll eat and release the big breeders; wet your hands, support the fish's belly and get it back in the water fast.
