Mulloway in the Swan River: A Land-Based Guide

Mulloway are ambush predators and they hold on structure. Pick your spot based on what’s under the water, not what’s convenient to the car park.

The Narrows Bridge pylons are the most famous jewie spot in the river for good reason — deep water, heavy current, massive concrete structure, and a constant conveyor belt of bait getting pushed through on the tide. Fish hold tight to the pylons on the down-current side and ambush anything swept past.

Point Walter gives you the sandbar and the drop-off at the end of it. Fish move along that edge at night, especially on a run-out tide pulling bait out of the shallows into deeper water. The drop is sharp, the current is real, and big mulloway use it as a highway.

Up the river a bit, the deep holes out from Ashfield Flats hold fish that most people never target. Less pressure, plenty of prawns and mullet, and a genuine shot at a solid jewie if you put in the hours. Down the other end, Bicton Baths and the wall along there gives you closer access to the saltier, bigger-fish water near the mouth.

Two windows really matter. Late autumn through winter is the classic Swan mulloway season — cooler water, mullet schools thick in the river, and long, dark nights that suit their feeding habits. A quiet winter night with a bit of tide and no wind is prime jewie weather, even if it’s the kind of cold that reminds you WA still won’t do daylight saving and the sun’s been down since about 5:30.

The second window is peak summer through into early autumn, when big breeders push up from the coast to feed. You’re fishing around the 2am slack most of the time — long after the 2pm sea breeze has finished shredding everyone’s umbrellas at Cott and the river has glassed off again. Night sessions beat day sessions about ten to one. Mulloway feed in the dark, they hate bright light on the water, and you’ll save yourself a lot of wasted casting by just accepting you need to be out there from about an hour before sunset through to sunrise.

Keep the rig simple. Around heavy structure like Narrows pylons, a fixed paternoster or short running rig keeps the bait pinned and stops fish burying you in the concrete. Over cleaner ground out from Point Walter or the deeper holes, a standard running sinker rig lets the bait move naturally on the tide — the sinker sits on the bottom, the fish picks up the bait and runs without feeling the weight.

Mainline wants to be 10-15kg braid, with a 30-40lb fluorocarbon leader of a metre or so. Heavier leader on structure, lighter in cleaner water when fish are fussy. Hooks are 6/0 to 8/0 circles for whole baits, stepped down to 4/0 for livies. Circle hooks do the work themselves — don’t strike, just let the rod load up and lift into it. Keep the drag sensible; a big fish in current will test knots, leaders and your ability to stay calm at 3am.

Bait quality is the single biggest thing separating anglers who catch jewies from anglers who don’t. Fresh mullet (not last month’s freezer burner), fresh squid (caught that afternoon, not the pre-packed rings) and a quality pilchard are the bread-and-butter baits — between them they cover most of what a Swan jewie wants to eat. Fresh tailor fillet — butterflied, skin on — pumps out oil and is hard to beat through winter. A live herring drifted under a float on lighter gear near structure is an excellent secondary option when you can get them, especially around the pylons.

The tackle shop bloke who tells you frozen pilchards will do the job isn’t lying exactly, but he’s also trying to move stock. Catch your own bait that afternoon if you can. It genuinely matters.

Rule of thumb: the last hour of the run-out into the first two hours of the run-in is prime. Fish the slack around the change. Dead water catches bugger-all — you want moving water pushing bait past structure, then that magic quiet window at the change when predators move in to mop up.

Moon phase matters too. The few days either side of full and new moons get the tides really moving, and moving water means feeding fish. Check the tide chart, wind and solunar for your chosen spot on BiteCompass before you commit to a long drive and a cold night — a 25-knot southerly will wreck Point Walter but barely ruffle the water at Narrows.

The number-one skill in Swan mulloway fishing is sitting still. Most sessions produce nothing. Some produce one bite all night. You need to be the kind of angler who’s content watching a rod tip for six hours — and who doesn’t wind in to check the bait every twenty minutes like the bloke next to you at the jetty who won’t stop asking if you’ve “seen the Dockers game.”

When you do get a big fish, treat it properly. Big mulloway are slow-growing breeders and releasing the genuine monsters is the right call. Keep them in the water if you can, support the belly, unhook with long-nose pliers, and get them moving again before they tire out. Photos are fine — thirty-second photos, not five-minute ones. For bag and size limits, check current rules with DPIRD before you head out.
