SQUID FISHING SYDNEY HARBOUR — JIGS, TECHNIQUE, LOCATIONS

THE TWO SPECIES — SOUTHERN CALAMARI VS ARROW SQUID

Sydney waters hold two squid species and you target each one differently. Both are present year-round, both eat the same prey items, but the locations, depths, and seasons skew different ways. Identifying which species is biting tells you what to change.

Southern calamari (Sepioteuthis australis)

The premium eating squid. Fat, oval-shaped mantle, wide stabilising fin that runs the entire length of the body. Caught most often around weed, kelp, and structure in 2–8 m of water. Light brown to amber colour when caught, transitions to pink and pale-cream as it stresses. Average mantle length around Sydney is 18–25 cm. Trophy fish run 35–40 cm mantle. Active across the day with peak periods at dawn, dusk, and after dark under structure or lights. Holds in tight territory — find one, you usually find more.

Arrow squid (Nototodarus gouldi)

Faster, leaner, more pelagic. Long pointed mantle with the fin only at the rear third. Caught most often in 10–30 m of water over rubble, sand, and reef edges. Reddish-brown when caught, transitions to white. Average mantle 20–28 cm. Trophy 40 cm plus. Active mostly at night and dawn. Schools move — find them and they are gone an hour later. Pursue, do not anchor.

MONTH BY MONTH — WHEN EACH SPECIES PEAKS

Calamari are year-round in Sydney with two soft peaks. The autumn bite (March–May) consistently produces the heaviest catch rates as juvenile squid grow through legal size and aggregate around the harbour kelp lines. The spring bite (September–November) is the trophy bite — older fish that survived winter return to spawn on the inshore weed beds.

Arrow squid peak November to February, dropping off through autumn. They follow bait schools and water temperature. The harbour mouth and the deeper sections of the lower harbour fish best in mid-summer. Northern Beaches inshore (15–25 m) holds them through January.

Winter (June–August) calamari fishing is slower but the trophy fish bite under the bridge lights at night. Less competition. Fewer boats. The biggest squid of the year come out of those winter night sessions for anglers who put in the time.

JIG SELECTION — SIZE, WEIGHT, COLOUR, UV

Squid jigs are sized in inches by Japanese convention. 2.5, 3.0, 3.5, and 4.0 are the sizes you carry for Sydney work. Each size has a corresponding sink rate measured in seconds-per-metre. Match the size to the depth and the current. Wrong size, wrong sink rate, wrong number of squid.

Colour by water clarity and light

The colour question gets over-complicated. Three colour families cover every Sydney situation. Pink (bright pink, cherry pink, hot pink) is the all-purpose option — it works in clear water at dawn, in stained water at midday, in clean water under bridge lights at night. Orange (bright orange, gold-orange) is the dawn and dusk specialist for clear harbour water. Glow / UV (white, lime, blue-glow) is the night and deep-water option, especially under artificial light where it lights up like a beacon.

The trick most anglers miss is rotating jigs every 15 minutes if not getting hits. Squid investigate a jig once. If they reject it, throwing the same jig for an hour wastes time. Change colour, change size, change action, then move spots if nothing changes.

UV — when it actually matters

UV-charged jigs need light to "charge" before working in the dark. Flash them with a torch or LED for 30 seconds before each drop. Under bridge lights or pier lights the UV picks up enough ambient light without manual charging. In open water at night without artificial light, UV does nothing — use a regular glow jig charged before each cast.

THE RISE AND FALL RETRIEVE — EVERY VARIANT EXPLAINED

The default — slow rise, controlled fall

Cast the jig. Let it sink to the depth the squid are holding (count seconds, match to the jig sink rate). Once at depth, the retrieve is a series of upward lifts followed by controlled drops. Lift the rod tip 60–90 cm in a smooth motion taking about 1 second. Pause for 2–3 seconds while the jig falls back through the strike zone. Wind in 2–3 turns of slack. Repeat. The strikes come on the fall, not the rise. Watch the line — a "tick" or a sudden line-going-light is the squid grabbing the jig.

The twitch — for active fish

When you see squid following or when you spot one in clear shallow water that has not committed, the twitch retrieve provokes a strike. Two sharp wrist flicks of the rod tip in succession, then pause for 2 seconds, then repeat. The jig darts erratically and triggers a reactive grab. Active in clear water at dawn, dusk, and around lights.

The deep slow-roll — for cold-water winter fish

In June–August water at 14–16°C, squid are sluggish. The standard rise-and-fall is too aggressive. Slow-roll the jig along the bottom — cast, sink, then just slow-wind with occasional gentle rod-tip lifts. Strikes feel soft, easy to miss. Set the hook on any unusual weight or tick.

The pendulum — for hovering jigs

Off a stationary wharf or jetty in current, work the jig as a pendulum — let the current carry the jig in an arc while you slowly raise and lower the rod tip. The jig swings sideways with the flow and the squid intercept on the lateral move. Works best from the harbour wharves with tidal flow under the structure.

THE BRIDGE-LIGHT BITE — THE MOST UNDERFISHED WINDOW IN SYDNEY

Sydney Harbour has multiple bridges and wharves with overhead lighting that throws a pool of artificial light onto the water at night. Spit Bridge, Iron Cove Bridge, Glebe Island Bridge, Pyrmont Bridge, the Cahill Expressway approaches — every one of them produces calamari on summer nights and winter cold spells alike. The mechanism is straightforward — the lights attract baitfish (yellowtail, garfish, slimy mackerel), and the squid follow the bait into the lit zone.

The technique under lights is different from daytime jigging. Cast to the EDGE of the light pool, not the centre. Squid stage in the dark zone and ambush bait that swims into the lit edge. Drop your jig 5–8 m from the boundary of the light into the shadow. Slow-roll it back toward the lit zone, with the rise-and-fall action. The strike usually comes within two metres of the light boundary.

Best window: 2 hours after sunset to about 2 am. Lit-bridge sessions on cloudy nights with no moon outfish bright moon nights by a factor of two — moonlight dilutes the contrast between the lit zone and the surrounding water, the squid disperse. Cloud cover concentrates them.

WHERE THEY HOLD — WHARVES, KELP LEDGES, BRIDGES

ROD, LINE, LEADER, AND THE DROPPER-JIG QUESTION

Rod

A dedicated egi (Japanese term for squid jigging) rod runs 8 to 8.5 feet, fast taper, 1–3 kg or 2–4 kg line class. The fast tip is what makes the rise-and-fall action work — soft rods cannot impart the twitch crisp enough. Egi rods are designed specifically for the lift-pause cadence. If buying just one, a 8 ft 1–3 kg works for everything from 2.5 to 3.5 size jigs.

A 7 ft light spinning rod (rated to 4 kg with a fast tip) works as a starter. Surf or beach rods are too heavy for the technique — the tip is too slow and the jigs do not work right.

Line

10–15 lb braid is the standard. Braid is essential — squid jigging is a feel game, and braid transmits the soft tick of a squid grabbing the jig in a way mono cannot. Bright-coloured braid (yellow, pink) helps you watch the line for indicator hits during the fall.

Leader

2 m of 12–20 lb fluorocarbon attached to the braid with an FG knot. The leader keeps the jig connected to fluorocarbon (less visible to squid in clear water) and provides abrasion resistance against the kelp and pylons.

The dropper-jig question

Some anglers run two jigs — a 3.0 size at the leader end and a 2.5 dropper 60 cm above. Doubles your strike zone. But it doubles the tangle rate too, and a single hooked-up squid on either jig means the other one is dragged through the strike zone and reduces follow-up chances. Recommend single jigs for beginners. Dropper-rig adds 30% to catch rates for experienced anglers in productive water.

HOW TO CLEAN A SQUID IN UNDER A MINUTE

Squid cleaning intimidates beginners and is the main reason home cooks avoid them. The technique is fast once you have done five.

1. Pull the head and tentacles out. Reach inside the mantle, find where the head attaches at the back, and pull steadily. The head, tentacles, ink sac, and most of the guts come out as one piece. About 4 seconds.
2. Remove the plastic-like quill. A long transparent strip ("the pen") sits along the inside of the mantle. Slide it out with two fingers. About 2 seconds.
3. Rinse the mantle. Squeeze under running water. Strip the purple skin off the outside with a thumb. The mantle goes white and clean. About 15 seconds.
4. Save the tentacles. Cut the head off below the eyes. The tentacles are excellent eating — leave them whole or chop them into strips. About 10 seconds.

Total time: under a minute once practised. The mantle goes whole into a freezer bag for grilling, or strips for calamari rings. The tentacles go separately. The head, eyes, beak, and guts are bait or compost.

USING FRESH-CAUGHT SQUID AS KINGFISH BAIT

Fresh-caught squid is the single best kingfish bait in Sydney Harbour. The mantle is firm, holds on a 5/0 hook, and stays in front of cruising kingfish for 20 minutes of soak time. Yellowtail kingfish eat squid as a primary food source on the harbour reef systems and around the heads.

Rig: a 6/0 wide-gap hook through the mantle from inside-out about 5 cm from the cut end. Add a stinger 5/0 hook 5 cm further down through the tail. The tail of the mantle waves in the current and triggers the strike. Fish this rig under a balloon (drifting kingfish from a boat) or weighted to the bottom (mulloway and snapper from a wharf).

If you have a kingfish session planned, jig squid 90 minutes before — fresh bait is unbeatable. See the Sydney kingfish guide for the full rig and target spots.
