Land Based Flathead: Melbourne Spots and When They Bite

Flathead are caught all year from Victorian shores. They are not a seasonal fish here, and there is no closed season. The fishing improves as the water warms from October to April. The falling tide in the early morning is the classic window.

Flathead is not one fish. Victoria has several, and the law treats them differently. That is the first thing to understand, because the size limit you carry in your head from another state will be wrong here, and the limit for one flathead is not the limit for the next.

This guide covers the shore only: piers, jetties, breakwalls, river mouths and the bayside sand you can reach on foot. It starts with the rules, because the rules decide what you can keep before anything else about the session matters.

The limits, and why the species matters

Victoria and New South Wales both split flathead into two groups with different rules. Get this wrong and a legal fish becomes an offence.

Victoria, from the Victorian Fisheries Authority. Flathead of all species except dusky flathead have a minimum legal size of 27 centimetres and a combined bag limit of 20 for one or more of those species. Dusky flathead have a slot: 30 centimetres minimum, 55 centimetres maximum, and a bag limit of 5. Dusky flathead cannot be filleted in or on Victorian waters. They stay whole or in carcass form until you are away from the water. Filleting at the cleaning tables at a boat ramp is allowed.

The line that catches people out. For regulation purposes, any flathead caught in Lake Tyers, or in any estuary east of Lake Tyers, is treated as a dusky flathead. That covers Marlo and Mallacoota. A 40 centimetre fish is legal there. A 60 centimetre flathead other than a dusky is legal at Altona. Any 60 centimetre flathead must go back at Lake Tyers.

New South Wales, from the NSW Department of Primary Industries and Regional Development. Dusky flathead have a slot of 36 to 70 centimetres, a daily bag limit of 5 and a possession limit of 10. Bluespotted flathead have a minimum of 33 centimetres, a bag of 10 and a possession of 20. Those dusky rules took effect on 1 August 2026. Before that the minimum was 36 centimetres with a bag of 10 and one fish allowed over 70 centimetres.

Rules change. Check the Victorian Fisheries Authority page and the NSW saltwater limits page before you fish. Both were read for this guide on 5 November 2026.

What season means for flathead

Here is the honest answer, because a lot of writing about flathead seasons is loose with it. There is no flathead season in the closed-season sense. The Victorian Fisheries Authority lists a size and a bag limit for flathead and no closed period. New South Wales has no closed season for dusky flathead either. The fish are present and legal to take all year in both states.

What people mean by season is when the fishing is easier. That is real, and it differs by area. Our records have flathead as year round in Victoria and stronger in the warm months. For New South Wales they have dusky flathead from September to May, strongest October to April.

So read season as an intensity, not a gate. Winter does not stop you. Our NSW dusky research has the fish moving deeper in the cold. For a land based angler the practical read is to try further out along a pier.

Why the water is warmer than the air in spring

This is the likely reason spring mornings can fish before the air feels warm. It is reasoning, not a flathead measurement.

Water holds heat better than air. In spring the bay warms slowly and steadily while the air swings hot and cold around it. On a cold morning the water can be several degrees warmer than the air above it. Flathead sitting on the bottom are not exposed to that cold snap in the way you are, so a cold dawn in October is not the same thing for the fish as it is for you.

Our working band has flathead active between about 16 and 25 degrees Celsius, best near 20, and sluggish below 15. That band is our calibration, not a measurement in Victorian water.

Tide: the short version, and where the detail lives

The full mechanism of how a falling tide funnels bait off the flats is in our Victorian tide guide. It is not repeated here. What matters for flathead specifically is the timing.

The run-out is the long standing preference. Our own notes on flathead put a falling tide in the morning, roughly from 5 am to 9 am, at the head of the list. That combination, water draining off the shallows and low light over it, is a common plan among Melbourne flathead anglers.

Be clear that this is a preference and not a measured law. It rests on angler consensus. One piece of research in our own files ranks the incoming tide above the run-out instead. Nobody has measured either against catch with an effort control, so the two positions sit unresolved. Fish the run-out because it is where the weight of experience points. Do not walk off a pier because the tide is pushing in.

Melbourne spots

These are all in Nibble and all list flathead, which means each one has live tide, wind and water temperature behind the link. Depths come from our spot records. The notes on where fish hold are field guidance, not measurements. Port Phillip is the core of it, because flathead suit its sandy ground.

Inner bayside, close to the city

St Kilda Pier. About 6 metres of charted depth at the end, and a long pier that puts you over sand and broken ground. Try the shallow sections either side in the warmer months, and the deeper end in winter.

Brighton Pier and Sandringham Breakwater. Both sit over about 4 metres. Brighton gives you the sand between the pier and the bathing boxes, which is worth working on a run-out. Sandringham is a breakwater rather than an open pier, so work close to the structure.

Black Rock Jetty and Beaumaris Pier. About 3 and 4 metres. Both work the sandy bottom either side. Read the sanctuary note on Beaumaris before you go, because Ricketts Point Marine Sanctuary starts less than a kilometre to the south west at Table Rock, and fishing is prohibited inside it.

Altona Pier. About 2.5 metres, so it fishes shallow. Anglers rate it as a low tide option, when there is less water for the fish to spread through.

South east bayside

Mordialloc Pier. About 2 metres, with the creek mouth adding a channel and a bit of bait movement. It is shallow, so it is an easy session on a calm day.

Frankston Pier and Seaford Pier. About 3 and 2.5 metres over sand. Both are simple sandy options with a short walk to deep enough water.

Mornington Pier. The deepest pier on the list at about 8 metres at the end. That depth gives you the option to fish deep in winter without a boat.

Western shore and the rivers

Williamstown, Gem Pier. About 3 metres, sand between the pier and the shore. A gentle spot to learn on.

Werribee River Mouth and Maribyrnong River at Footscray. About 2 and 3 metres. These are the estuary end of the range, where the bottom is mud and sand rather than clean sand, and where a flathead is as likely to take a bait meant for bream as anything else.

Wyndham Harbour Rockwall. About 4 metres along the wall. Access is limited. The marina side has been fenced and security may move anglers on after hours, so fish the ramp side and expect company.

Portarlington Pier, St Leonards Pier and Clifton Springs Pier. Between 2 and 6 metres on the western side of the bay. St Leonards is the deeper of the three and gives you a better shot at fish holding out from the shore.

Western Port and Gippsland

Hastings Jetty, Stony Point Pier, Cowes Jetty and Rhyll Jetty. Western Port runs bigger tides than Port Phillip and the water moves harder, so a moving tide is the time to plan around. Depths run from about 2 to 4 metres.

The Gippsland Lakes and the far east are the dusky flathead country. Lake Tyers, Paynesville Jetty, Metung Pier, Lakes Entrance, Mitchell River Silt Jetties, Marlo Jetty and Mallacoota Wharf. All shallow, all about 2 metres. Remember that Lake Tyers and everything east of it is under the dusky rule, so the 30 to 55 centimetre slot and the bag of 5 apply.

Sydney, briefly

Dusky flathead are a New South Wales fish first and a Victorian fish at the edge of their range. If you fish Sydney, the estuary water is where they live, and the 36 to 70 centimetre slot is the number to carry.

Narrabeen Lagoon, North Narrabeen Bridge. About 2.5 metres of sheltered lagoon water. Work the channel edges around the bridge.

Palm Beach Ferry Wharf on Pittwater, and Spit Bridge, Middle Harbour. About 4 and 5 metres. Both are pylon spots with current, and both stay fishable when the swell rules out the ocean rocks.

Wally’s Wharf, Dolans Bay, Lilli Pilli Baths and Wharf, Como Pleasure Grounds, Tom Uglys Bridge and Captain Cook Bridge. All in the Port Hacking and Georges River systems, between 3 and 4 metres, and all sand channel and pylon water rather than rock.

Dusky flathead is a separate species page if you want it: dusky flathead.

How to fish them from the shore

Get the lure on the bottom. Flathead lie buried in sand and ambush upward. A soft plastic that swims a metre off the bottom passes over them. A paddle tail on a jig head, hopped along the sand, brings the lure into the strike zone. The weight depends on the depth and the tide: enough to touch bottom, not so much that it drags.

Slow down more than feels right. Two common mistakes are retrieving too fast and lifting the lure off the bottom. Two hops, then let it settle on a tight line. Many flathead take on the drop or on the first movement after it settles.

Bait works, and it is simple. A running sinker down to a 3/0 or 4/0 hook with a strip of squid, a pilchard or a live poddy mullet is a standard flathead rig from any of the piers above. From the shallow piers, a bait cast well out and left to sit in the current does the same job as a lure with less effort.

Colour matters less than depth. Every tackle shop sells a flathead colour. What puts fish on the bank is the lure arriving at the bottom at the right speed. Change weight and speed before you change colour.

Handle them properly. Flathead have sharp gill covers and a spiny head. Wet your hands, support the body, and use a lip grip or a wet towel rather than the gills. A fish you release should go back quickly and with its slime layer intact.

Filleting and the dusky rule. On Victorian waters a dusky flathead stays whole or in carcass form until you are away from the water. That is the law, not etiquette. Fillet at the ramp cleaning tables or at home.

Safety and access

A pier has its own hazards. Wet timber, low rails and a rising tide behind you are the usual problems, and none of them involve the fish.

Two access points need specific care. At Wyndham Harbour, the rockwall access is fenced and security can move people on after hours. At Beaumaris Pier, the Ricketts Point Marine Sanctuary boundary is close to the west and it is a no-take area. Use the current boundary map rather than a memory of where it used to be.

You need a Victorian Recreational Fishing Licence unless you are exempt. Buy it through the Victorian Fisheries Authority. New South Wales requires a recreational fishing fee for most anglers.

What the evidence cannot tell us

Our own research is worth being straight about, because flathead is a species where a lot of confident writing rests on very little.

The tide preference is angler consensus. Nobody has measured flathead catch against tide phase with an effort control. The run-out bias is what experienced anglers report and nothing more.

The research behind our dusky flathead profile is almost entirely New South Wales estuary work: Sydney Harbour, Botany Bay, the Hawkesbury, Lake Macquarie. There is no Victorian flathead data in it at all. Dusky flathead are at the southern margin of their range in Victoria, and every temperature band and tide preference we apply here is an import. Treat Victorian dusky advice as informed extrapolation rather than measured local fact.

One claim in the research we do not use: a population level winter exodus from estuaries. The rest of our research contradicts it, and the primary study does not support it. Our best reading is that dusky flathead stay in the estuary and move deeper in winter. Applying that to a Melbourne pier is our inference, and it is why we suggest the deeper piers in the cold months.

Solunar period times have no measured support for this species and are not part of the plan.

How to read the conditions

• Worth a session when water temperature is in the high teens or above, the tide is running out through the morning, and the wind is light enough to hold bottom contact.
• Fish it anyway when the water is cold. Move to the deepest pier you can reach, slow everything down, and expect fewer fish rather than none.
• Go shallow on the low at Altona, Mordialloc, Werribee and the Gippsland Lakes, where anglers expect draining water to push fish into less space.
• Go deep on the high from Mornington, St Leonards and Stony Point, where anglers expect the fish to spread out.
