Mulloway — also known as jewfish, jew, jewie or silver king — is Sydney's most-mythologised land-based fish. The honest expectation: most Sydney mulloway are caught between 11pm and 4am, within three kilometres of the Harbour Bridge or near the major river bridges, on a slack-water push under a new moon. The fish over a metre exist, they are landed every winter, and almost none of them come to anglers who fish only the easy hours.
Argyrosomus japonicus. In NSW and Victoria the fish is officially mulloway. In Queensland and across the NSW colloquial it is jewfish, jew or jewie. The smaller fish under about five kilos — anything below a fillet that holds together properly — earn the name "soapy" for the soft, almost soap-textured flesh of immature fish. The bigger fish over fifteen kilos pick up another name on the rocks — silver king — usually after dark by an angler who has just landed one.
The names matter because the search variants matter. A Reddit post titled "35 kg jew off the rocks" and a tackle-shop conversation about "a soapy on a Sugapen" and a regulation page titled "mulloway minimum size" are all the same species. If you are reading Sydney fishing reports across the boards, all four words point at Argyrosomus japonicus.
The numbers below come from NSW DPIRD's recreational saltwater rules, current at September 2025 when the Fishare regulations page was last verified against the official guide. Always cross-check against the live NSW mulloway regulations page before you keep a fish.
The minimum size is set high for a reason. Mulloway are slow-growing, and a 70 cm fish has already taken six to eight years to reach legal length. Anything shorter goes back, fast and wet. The bag is two; the possession is four — meaning even if you fished two days in a row at the legal bag, you cannot stack a freezer with more than four fish at one time.
Mulloway are in Sydney all year. What changes is where they hold, what they eat, and what size class shows up. Two windows produce the trophy fish — autumn into the breeding push, and the cold-water winter ledge fishery — and the summer school-fish run keeps the rod bending in the warmer months. The calendar below is the practical one: when to fish, where to fish, and what to expect.
Big school fish migrate up the coast. Off the rocks at dawn and through the night. Average run 75–95 cm; occasional fish over a metre. Rising barometer kills the bite; pick the day before a southerly buster.
Mature fish move into the Harbour for breeding. The bridge pylons fire. Slack tide on a new moon at 1am is the textbook window. Average run 80 cm to a metre; the fish hold close to deep structure.
The legendary 30-kilo class window. Cold-water fish hold near deep ledges inside the harbour and around the headlands. Falling barometer ahead of a winter front, new moon, slack tide — this is when the trophies come ashore.
Post-spawn the fish thin out and feed less aggressively. Late-spring cold snaps still produce on the headlands. The estuary is quieter. Persistent rain that pushes river run-out into the harbour can fire a short bite window.
Mulloway are unusual in that conditions which crater the bite for every other Sydney species — falling barometer, dark moonless nights, pre-storm onshore swell — are the conditions that switch them on. Plot the lunar calendar and the barometer trace on the same chart and the productive sessions sit in the overlap. The forecast page tracks both — see the Sydney forecast for daily lunar and pressure scoring.
Sydney is one of the best urban mulloway fisheries in the country — the harbour holds a resident population, the headlands either side of the heads produce a stream of summer schoolies and winter trophy fish, and three river systems (Hawkesbury, Georges, Parramatta) all have bridge structure that holds mature fish at slack tide. The list below is ordered by consistent land-based access, not by trophy potential.
The classic Sydney land-based jewie ground. Deep water inside fifteen metres of the foreshore, structure under your feet, current edges that funnel bait. Walsh Bay through to Dawes Point on the south side, Milsons Point and Kirribilli on the north. The deep wall sections at strong slack hold mature fish that move in close to feed on squid and yellowtail. (The Garden Island side is a working RAN base — access is restricted; the publicly-fishable foreshore is on the north shore plus the south-side wharves.)
Middle Harbour holds a serious jewfish population that gets less attention than the main harbour because the access points are smaller and the parking is harder. The Spit Bridge pylons and the Roseville Bridge piers both fish well after dark on the slack — kayak under the bridge or fish from the abutments where shore access permits. The current edges either side of the pylons concentrate bait and the fish hold within a rod-length of the structure.
One of the most consistent shore-based jewie spots in Sydney, and one of the least crowded. Como Bridge spans deep water, the pylons hold structure, and the picnic ground on the southern side gives a kayak launch and a walk-in foreshore. Slack-tide bite cycles run with metronomic regularity here — a six-hour autumn night will produce two shots: one on the high slack, one on the low. Fish run smaller on average than the main harbour but the average rate of fish in the boat is higher.
Boat or kayak fishery. The deep holes scoured around the railway bridge pylons hold mulloway year-round and the autumn run-up here produces the largest average fish of any of the listed locations — fish over a metre are common, and the freshwater push through after rain only switches them on. Anchor up-current of a pylon, drift live bait on the back of the boat, and the bite cycle peaks on the slack either side of high tide. The Brooklyn area has full ramp access, marine fuel and tackle.
Off-the-rocks land-based mulloway is the most photographed and the most dangerous of the Sydney options. South Bondi Point through to Mackenzies Point holds summer school fish on a settled night; Boora Point and the Mahon Pool ledge fish through the winter big-jew window for the trophy class. The fish that feature in the most-upvoted Reddit Australia fishing posts of the year almost all come from this stretch — 30-kilo land-based jewies are the holy grail catch on these boards, and the south-east Sydney rocks are where the holy grail gets landed.
The deep channels inside Botany Bay — the dredged main channel runs nine to twelve metres against shallower flats — concentrate mulloway around the channel edges and the rock walls. La Perouse on the south side, the Yarra Bay wall, and the runway wall on the north side all fish well from a kayak or small boat after dark. Less wave management than the open rocks and easier ramp access than the inner harbour pylons.
Three variables decide the mulloway session more than any other. Tide, moon, barometer — and the answer is not the one you expect from reading guides for other species.
Slack water is the mulloway window. Not the run-in. Not the run-out. The fifteen minutes either side of high or low when the current dies and the column stills. I have taken more Sydney mulloway on slack water than on rising tide by a three-to-one margin, and the bigger fish skew the ratio further. The reason is mechanical — mulloway hunt by sound and lateral line in low-visibility conditions, and they pin bait against structure when the current is not doing the work for them. A six-hour overnight session is two thirty-minute windows; plan the trip around the slack.
New moon and the days either side. The dark moon, when the night sky offers no ambient light and the fish have the full advantage of their lateral-line hunting. Moonlight reduces their edge — a bright full-moon night will produce, but the bite rate drops noticeably compared to the same session two weeks later under a new moon. The Sydney big-jew Reddit posts are dominated by new-moon dates. Pull up the lunar calendar on the Sydney tide chart and circle the new moons before you commit a session.
A falling barometer ahead of a front is mulloway gold. Where snapper switch off and bream go quiet and kingfish disappear, mulloway switch on. The textbook trifecta is a dropping low-pressure system, a new moon, and a slack tide that lines up after midnight. It produces the trophy fish on a five-to-one rate over calm, clear, high-pressure nights of the same length. This is the rare Sydney species where "go when the conditions are bad" is the correct call — pre-storm overnight sessions outproduce settled nights by a wide margin.
Mulloway are predators on size-appropriate bait. The rule is live, fresh, big — every step down in any of those three is a measurable drop in bite rate, and the trophy fish almost never come to undersized offerings. The order below reflects what actually works in Sydney across all the listed grounds.
The gold-standard live bait. Caught fresh that session on a sabiki off the pylon, pinned through the shoulders on a 6/0 octopus circle and either slow-trolled past structure from the boat or pinned under a balloon off the rocks. A live yakka in the right place at the right tide will outfish every other bait two-to-one. Keep them lively in an aerated bucket; a stressed yakka pinned to a hook fishes like dead bait inside twenty minutes.
Caught fresh that night with squid jigs in the same harbour you are jewfishing. The peerless deepwater pylon bait — mulloway on the bridge pylons, the inner harbour deep walls, and the Brooklyn railway bridge feed predominantly on squid through autumn and winter, and a live squid presented near structure on the slack draws the larger class of fish. No bought squid, no frozen squid — fresh-caught, live, that night.
The classic land-based rock-fishing bait. A whole mullet on a 9/0 octopus, butterflied to release scent, cast to the wash edge and the rod set with the drag light. For the trophy class off the south-Sydney headlands this is the bait that produced the photographed 35-kilo fish that featured in the top-of-year Reddit Australia post. Big bait deters small fish — a soapy will not commit to a head bigger than its own — which is exactly what you want when you are fishing for the metre-plus class.
Berkley Gulp Nemesis 6", ZMan Diezel Minnow 5-7" or a Squidgy Slick Rig in the 110 mm size. Slow-rolled near structure on a quarter-ounce jighead, the retrieve as close to the bottom as you can keep without snagging. The bite is a thump rather than a tap — a clean strike is unmistakable. Plastics work better in the boat or kayak than off the rocks; the boat lets you keep the lure in the productive water column past structure, which is hard from a fixed rock platform.
Samaki Vibelicious 100 mm, Zerek Fish Trap 95, TT Switchblade 1/2 oz. Lift-and-drop over Sydney Harbour drop-offs and Botany Bay channel edges — a long lift of the rod tip, let the lure pendulum back to the bottom on the drop, and the strike comes on the fall ninety percent of the time. Vibes work well in winter when the fish hold deeper and a slow-rolled plastic spends too much time out of the strike zone.
Three rigs cover everything: a rocks rig for the headlands, a boat rig for the harbour and Botany Bay, and an estuary rig for the lighter bridge work. Build all three or pick the one that matches your most-fished water — the worst mistake is taking estuary gear to the rocks, where you will either bust off the only fish of the night or drag the cast too short to reach the wash edge.
| Rocks · headlands | Boat / kayak · harbour | Estuary · bridges | |
|---|---|---|---|
| Rod | 8-10 ft medium-heavy spin | 7 ft heavy spin | 7 ft medium spin |
| Reel | 5000 class; 6000-8000 for trophy | 4000-5000 class | 4000 class |
| Braid | 30 lb | 30 lb | 20 lb |
| Leader | 50 lb fluoro, 2 m | 40 lb fluoro, 1.5 m | 30 lb fluoro, 1.5 m |
| Hook (bait) | 7/0–9/0 octopus circle | 5/0–7/0 octopus circle | 4/0–6/0 octopus circle |
| Hook (lure) | — | 4/0–6/0 wide-gape jighead | 4/0 single assist on vibes |
A two-metre 50 lb leader handles more abrasion against pylons and rock-shelf edges than a half-metre 80 lb leader. Mulloway will rub a leader against structure during the fight and the breaking point on any leader is the abraded section, not the knot. Always rig with enough length that the leader-to-braid splice sits well above the rod tip on the cast — that way the leader is what touches structure, never the braid. The FG knot is the connection that holds; the Albright is the backup if you cannot tie an FG in the dark.
Circles for bait deliver clean jaw-hookups that allow release without internal damage on undersized fish. Wide-gape jigheads or single-assist for plastics and vibes give a higher hook-up rate on the slow lift strike that mulloway prefer. Treble hooks on hard-body lures are the wrong choice — too many fouled hookups and too much damage on releases. Single assists on vibes are the small change that swaps a 60 percent landing rate for an 85 percent landing rate.
This section is not optional. Sydney loses anglers to the rocks every year and the most-reported single common factor is solo night fishing on dark, unfamiliar headlands without a lifejacket. The mulloway bite that pulls anglers onto the rocks at 1am is the same set of conditions that puts you in the water: pre-storm swell, dropping pressure, dark moon, slick rocks.
For the full rock-fishing safety protocol — gear list, the platform-survey routine, the wash-clock reading method — read the Sydney rock fishing safety guide before any first session at a new headland.
A big mulloway fights hard but tires quickly. The bigger the fish, the more important it is to land it fast — extended back-and-forth on light drag exhausts the fish past the point of survival on release, and degrades the table quality even on kept fish through lactic-acid buildup in the flesh. Pin the drag at landing weight, work the fish in firmly, and end the fight in under fifteen minutes for anything inside a metre.
Net at the rocks where possible. Gaffing kills release fish and is unnecessary on anything under a metre — a knotless rubber-coated net the right size and a lip-grip on the boat-side handle lets you measure the fish in the water, decide to release or keep, and only then commit. Gaffs are for fish you have already decided to keep and that are too big to net. A trophy mulloway gaffed in the gut is a wasted fish.
Dispatch immediately with a spike between the eyes, bleed via the gills into a bucket of seawater, and put the fish straight onto an ice slurry. Pre-rigor flesh is firmer and holds storage better; a fish left to die slowly in the boat develops soft patches in the fillet and the eating quality drops in the first 24 hours. The handle-and-dispatch routine on the flathead dispatch guide scales up directly to mulloway — same iki-jime principle, larger spike, more thorough bleed.
The flesh is bright white, large-flake and excellent. Slow-cook or grill with skin on. The trophy fish — fillets you can almost not see through — are best slow-grilled over coals or pan-baked at moderate heat with a butter-and-herb baste. Pan-frying a trophy mulloway fillet on a hot pan is a waste of a rare fish; the flesh dries out before the middle reaches temperature. Save pan-frying for the smaller portions cut from a school-class fish.
Mulloway are slow-growing and long-lived. A 70 cm fish is six to eight years old; a metre fish is twelve to fifteen; the metre-twenty trophies that occasionally come ashore on the south-Sydney rocks are pushing twenty years. The fish over a metre are the breeding population — the genetic stock that produces the next decade of jewfish for every estuary in NSW. Releasing a trophy fish is not just an option; in conservation terms, it is the correct option.
The trophy is the shot. Measure on a wet brag mat, photograph fast — one or two frames, not a portfolio shoot — and slide the fish back into the water head-first to flush oxygen across the gills. A revived big mulloway will hold against your hand at the side of the boat for thirty seconds, then kick away under its own power. That fish goes on to spawn another four or five times before age catches it; the photo on the camera roll is the same trophy whether the fish is in the esky or back in the harbour.

NSW DPIRD sets the minimum legal size for mulloway at 70 cm total length, measured from the tip of the snout to the tip of the tail. The daily bag is two fish per person per day and the possession limit is four fish. There is no closed season. Verified against the NSW DPIRD recreational saltwater fishing guide, last checked September 2025 — always confirm against the live rules page before keeping fish.
Live yellowtail (yakka) and live squid are the top two baits for Sydney mulloway, both caught fresh on the day of the session. Pin a live yakka under a balloon off the rocks or slow-troll past harbour structure; a live squid fished near pylons at slack tide produces the trophy class. For land-based rock fishing aimed at metre-plus fish, a whole fresh mullet or tailor head on a 9/0 octopus cast to the wash edge is the textbook approach.
The peak bite window for Sydney mulloway runs from 11pm to 2am, with the strongest bite cycle on the slack tide either side of high or low water within that window. Plan a session to start around 9pm and run through to 4am to bracket the peak. Mulloway also feed at dawn (the hour either side of sunrise) and on overcast pre-storm days, but the highest single-window catch rate is the slack-tide overnight on a new moon under a falling barometer.
The south-Sydney headlands from South Bondi Point through Mackenzies Point, Boora Point and Mahon Pool ledge are the most consistent land-based rock fisheries for Sydney mulloway. South Bondi fishes well for summer school fish; Boora Point and Mahon ledge produce the trophy winter class. These platforms sit inside Waverley and Randwick LGAs — both have declared their rock platforms under the Rock Fishing Safety Act, so a lifejacket is legally required. Confirm the current declared list at the NSW DPI page before you go. The platforms should never be fished solo on dark moonless nights. Walk the platform in daylight before you fish it after dark.
None — they are the same species, Argyrosomus japonicus. "Mulloway" is the official name used in NSW and Victoria regulations. "Jewfish" or "jew" is the NSW and Queensland colloquial. "Soapy" is the name for small immature fish under about five kilos (after the soft texture of the flesh). "Silver king" is the rocks-angler term for the trophy class over 15 kilos. All four refer to one fish.
The Sydney average run is 75 cm to 95 cm — a school-class fish in the five-to-twelve-kilo range. Fish over a metre are landed regularly through autumn and winter from the harbour pylons, the Hawkesbury bridge and the south-Sydney headlands. The trophy class — fish over 1.2 m and 25 kilos — comes off the rocks in the cold-water winter window. The largest Sydney land-based fish on record exceed 35 kilos and feature regularly in the top-upvoted catches on the Australian fishing boards.
