MULLOWAY — THE NSW JEWFISH PLAYBOOK

The basics, fast

Mulloway (Argyrosomus japonicus) — also called jewfish, jewies, butterfish or silver kings — are NSW's most iconic estuary and beach trophy fish. They're moody, lunar-driven, and famously frustrating; success comes from learning to fish around their habits, not against them.

• Range: Found from Burnett River in QLD all the way around to Onslow in WA. NSW carries the most consistent recreational fishery, with strong populations in every major estuary and along the open ocean beaches.
• Size: Schoolies of 60–80cm are common; legitimate "soapies" and slot fish 80–110cm; trophy fish 120cm+ (15kg+); the genuine giants 1.5m+ (30kg+) live in deep estuaries and along ocean rocks.
• Diet: Mostly fish — mullet, herring, slimies, tailor, squid, prawns, crabs. Big fish eat big baits. They feed by ambush, not chase.
• Lifespan: 30+ years for the big fish. A metre-long mulloway is around 7-10 years old — not a fish you should waste.

The lunar truth

If you take only one thing from this guide: mulloway are a lunar fish. Build your trips around the moon, not your weekend.

The peak bite is the four nights either side of new and full moons, with new-moon spring tides slightly favoured for ocean beaches and full-moon for estuaries (because fish hunt by moonlight). Within those moon windows, the best bite is usually:

• The bottom of the run-out tide — bait gets concentrated through holes and channels as the water drops
• The top of the run-in — for beach fish, when the tide pushes bait into the gutters
• Dawn and dusk on either of the above

Outside of new/full moon weeks the fishing isn't dead — but you're working harder for fewer fish. If you can only fish twice a month, fish the moon weeks. Don't waste your trips on the quarters.

Where mulloway hold

Mulloway are structure-and-current fish. Three habitats produce most of NSW's recreational catch.

Estuary deep holes

The classic NSW jewie water. Look for any deep hole within an estuary system — the Hawkesbury's Sackville Reach, Botany Bay's "the trench," Brisbane Water's "the Rip," Newcastle's Stockton Bridge holes. Holes deeper than 6m, especially below bridges, structure or river junctions, hold fish year-round. Fish on the run-out tide as bait gets flushed through.

Ocean beaches — the gutters

Open beaches with deep gutters running parallel to the sand are jewie classics — Stockton, the Tuncurry beaches, Forster, Crowdy, Sussex Inlet, Eurobodalla. Look for darker water (deeper) close to a sandbank where waves break — that's the gutter. Cast big baits into the gutter on the front of the run-in. Night fishing on a moon-week tide is the canonical session.

Wash, rocks and reef

Big mulloway live in the open ocean wash — kelp-fringed rocks, deep reef edges, headland points where the swell builds and bait collapses. Fish from the rocks at night with live mullet under a balloon or pin-rigged dead baits in the wash. This is where the metre-plus fish come from. Risky in big swell — pick your conditions.

Reading the day — what actually matters

Tide

The largest single variable for mulloway. Bigger tidal ranges = stronger water flow = more bait moving = more feeding fish. Spring tides (around new and full moon) consistently outfish neaps. Within a tide, the last hour of the run-out and the first hour of the run-in are the highest-percentage windows.

Water clarity and temperature

Mulloway feed by both sight and lateral line. They love a slight tinge of turbidity from rain runoff or a drop in clarity from churn — bait gets disoriented, fish get an easier feed. They tolerate a wide temperature range (15–24°C) but are most active around 18–22°C.

Pressure and weather

Falling barometric pressure ahead of a southerly change is a known mulloway trigger — they feed up before the front. Calm to moderate conditions outfish either dead-flat or rough; small swell stirs bait without making the water unfishable.

Storm wash and runoff

A heavy rain that pushes brown water into an estuary mouth or river system creates the year's best mulloway sessions for those who can read it. Fish the edges where dirty water meets cleaner — that's the feeding lane.

Gear — built for the bigger fish

Tackle splits cleanly by where you're fishing. The same rod that's perfect on Hawkesbury soft plastics is too light for Stockton at midnight.

Estuary spinning (boat or land)

• Rod: 7'2" 4-8kg or 7'6" 6-10kg, fast taper
• Reel: Stradic FL 4000–5000 or Saltiga 4000
• Line: 20lb braid
• Leader: 30–40lb fluorocarbon, 1.5m
• Lures: 5–7" soft plastics on 1/4–3/8oz jigheads (Squidgy Slick Rigs, Z-Man Diezel, Berkley Hollowbelly), suspending hard bodies (Megabass Vision OneTen)

Beach + rock baitfishing

• Rod: 12–14ft surf or 9–11ft heavy rock rod, 8–15kg rated
• Reel: Saltist 6000 / Stradic SW 8000 / overhead like Avet SX
• Line: 30–50lb braid, 2m mono shock leader (50–80lb)
• Leader: 80–100lb mono trace, 1m
• Hooks: 8/0–10/0 ringed circles for whole baits, 6/0 paternoster gangs for cut baits
• Sinkers: Star sinkers 4-6oz for surf, snapper leads 2-3oz for sheltered work

Wash and live-baiting

• Rod: 9-10ft 10-15kg medium-heavy rock rod
• Reel: Stradic SW 14000 or overhead
• Line: 50lb braid, 2m mono leader at 80lb
• Rig: Live mullet pinned on a 9/0 ringed circle, balloon rigged 1-3m above, drift through the wash

Bait and lure choice

Live baits — the most reliable

A live bait is hard to beat for mulloway. In order of effectiveness:

1. Live mullet (poddy or sea mullet) — the gold standard, both in estuaries and ocean
2. Live yellowtail / slimy mackerel — for ocean wash and deep estuary holes
3. Live tailor — proven big-fish bait, nowhere quicker to find than from the same beach
4. Live squid — exceptional in estuaries and reef systems
5. Live herring / yellow-eye mullet — for smaller schoolies in shallow water

Dead and cut baits

Big fillets work — fresh tailor, mullet, squid, salmon. The rule: fresher is better, bigger isn't always better, but matching the local bait always is. A 25cm whole mullet on the right night will outfish anything else on a beach.

Soft plastics

For estuary jewies, soft plastics worked slowly along the bottom in deep holes are exceptional. Squidgy Slick Rigs (110-130mm), Z-Man Diezel and Hollowbelly Shads in pearl, gold or natural mullet patterns. Slow lift-and-drop retrieve, almost dead-stick on the bottom. The take is often subtle — just weight on the line.

Hard bodies

Suspending minnows like the Megabass Vision OneTen, Daiwa Dr Minnow, and Storm Searchbaits work brilliantly along structure edges in estuaries — bridges, drop-offs, snags. Twitch-pause cadence, retrieve with the current.

Tactics — the high-percentage approaches

1. The night beach session

Pick a moon week. Walk the beach at low tide and identify gutters (deeper darker water sitting close to a sand bank). Set up an hour before dark on the start of the run-up. Two rods: one with a live or fresh dead bait in the gutter, one with a smaller bait closer to your feet. Fish through the change of light and the first 2 hours of run-up. Stay patient — bites come in pulses.

2. The estuary drift

Find a deep hole on a chart or sounder. Drift through it on the bottom of the run-out using soft plastics or live baits with just enough weight to stay in touch with the bottom. Mark every fish you encounter (not just hookups — sound returns matter) and re-drift the productive line. Concentration of effort beats coverage.

3. The bridge troll

Hawkesbury, Brisbane Water, Hunter — anywhere with road bridges over deep water. Troll suspending minnows along the structure edges on the run-out, focusing on shadow lines if it's a moon-lit night. Long, slow passes; current does most of the work.

4. Live bait under a balloon

Off the rocks or boat in the wash. Live mullet or slimy on a 9/0 circle, balloon set so the bait drifts at 1-3m below the surface, current carrying it through productive water. Patient game — but produces the biggest fish of any technique.

How to read tide and timing

A practical session-planning sequence.

1. Pick the moon. 4 nights either side of new or full. Outside this window, fish a different species.
2. Check the tide. Find the timing of the bottom of the run-out OR the top of the run-up that intersects with dusk/dawn or full dark. That's your session.
3. Check the weather. A falling barometer or a small southerly building is a green light. A 30-knot wind from any direction is a different night.
4. Watch the rain. Heavy rain flushing a system 1-3 days before your trip = bait flushed out, mulloway feeding hard. Time it.
5. Get your bait first. Catch your live mullet/yellowtail/squid in daylight. Don't waste prime feeding time fishing for bait.
6. Be in position before dark. Walk in. Set up. First cast in clean water before the light goes.

Regulations and ethics

Always verify current NSW DPI bag and size limits before your trip. As of 2026 the recreational limit is 2 mulloway per person per day, minimum size 70cm. The NSW DPI website has current rules.

Ethical handling: mulloway 1m+ are slow-growing breeders that drive the fishery's future. If you're catching them, photograph quickly, support the body, release in the water without lifting if possible. The fish you let go is the one your grandkid catches.

Common mistakes

• Fishing the wrong moon. Spending Saturday night working a quarter-moon tide when next weekend's full moon is the actual fish night. Plan trips around the moon.
• Bait too small. A small bait gets eaten by everything else first. For mulloway, go bigger than feels reasonable — a 25cm mullet isn't oversized for a 70cm fish.
• Wrong leader. 80lb mono leader looks heavy but mulloway aren't leader-shy in turbulent water. Going lighter loses fish in the wash.
• Setting hook too early. With circle hooks, just lift smoothly into the fish — don't strike. The hook does the work.
• Going on the wrong night. 25-knot easterly seas and 4m swell aren't a beach mulloway night. Wait for the right conditions; you'll catch more fish in fewer trips.
• Bright torches. White light at the water spooks fish in shallow estuary holes. Use red headlamps where possible; turn off at the water's edge.

The honest truth about jewies

Mulloway are NSW's most beloved trophy fish for a reason — and the most maddening. You'll spend nights with no bites. You'll get bricked by a fish in structure and replay it for weeks. You'll lose more big fish than you land in your first year of seriously chasing them.

What separates anglers who consistently catch mulloway from anglers who occasionally fluke one isn't gear or location. It's showing up on the right tide, on the right moon, in the right conditions. Read the calendar. Read the weather. Show up prepared. The fish reward patience, not effort.
