Brown Trout Fishing in WA

Tell most Perth anglers there is a brown trout fishery a couple of hours down the road and you will get a blank look. Trout belong to Tasmania, or New Zealand, or a calendar. But Western Australia has quietly held a small, genuine trout fishery in its south-west forests for over a century — and brown trout are the older, warier half of it.

This is not coastal fishing. It is cool, clear, freshwater stream and dam fishing on light gear, a long way from the nearest gutter. If you have only ever chucked metals at salmon in the wash, it is a completely different game.

WA Actually Has Trout?

It does. Trout have been stocked in WA for over 100 years, run today through DPIRD’s Pemberton Freshwater Research Centre. Brown trout (Salmo trutta) went into the south-west streams from the early 1900s and built small self-sustaining populations in the Donnelly, Warren and Lefroy Brook systems before the rainbow programme took over the heavy lifting.

The headline numbers today are rainbow trout — tens of thousands released each year ahead of the season. Browns still feature in some release years, but most caught now are wild-spawned holdover fish, which is part of their appeal. They run larger on average than rainbows, hold tighter to cover, and feed more selectively. They are harder to catch, and that is the point.

The Rules (and the Licence Question)

Here is the one that trips people up: you need a licence, but only one. A South-West Freshwater Angling Licence from DPIRD is required for all freshwater angling south of Greenough (29°S) above the tidal limit — every lake, dam, river and tributary in trout country. Unlike Tasmania, WA does not charge a separate inland angling fee on top; the one licence covers you. Under-16s do not need it, and you do not need a Recreational Fishing from Boat Licence to fish freshwater from a powered vessel. Marron, in their short summer season, need a separate licence again.

On the limits: current DPIRD rules set a daily mixed bag of 4 fish combined across brown trout, rainbow trout and freshwater cobbler, with a minimum size of 300mm. Note that the Shannon River is closed at all times, as are all Water Corporation drinking-water supply dams. Regulations and season dates change, so pull the current numbers from the DPIRD south-west freshwater guide before you drive down. Don’t take a number off a blog — including this one — as gospel against a fisheries officer.

Where to Fish

The brown trout heartland is the Pemberton/Donnelly catchment, but the fishery spreads from Dwellingup down to Walpole. Order here is roughly by drive from Perth.

Waroona Dam and Drakesbrook Weir

The closest serious freshwater fishery to Perth, about 90 minutes south. The two are a pair — Waroona Dam (Lake Navarino) is the big recreation lake, but Drakesbrook Weir is the cooler, smaller trout water, stocked annually with rainbow trout under the Waroona Troutfest program (browns in some years). Fish Drakesbrook at first and last light on small spinners, minnows or PowerBait off a light running sinker — it is small enough to work entirely on foot. Check the Waroona Dam forecast before you go, and don’t expect trout out of the big lake.

Wellington Dam (Collie)

About two and a half hours south, Wellington Dam is the largest reservoir in the south-west — a calm, jarrah-and-marri impoundment holding stocked rainbows, holdover browns and naturalised redfin perch. It is a slow-troll and bank-soak fishery more than a casting one; a kayak gets you onto the quiet points the bank crowds can’t reach.

Pemberton: Big Brook Dam, Lefroy Brook, Warren and Donnelly

This is the heartland. The Pemberton / Donnelly River area runs through karri country and holds the rare WA stream-trout fishery. Big Brook Dam is the easy, family-friendly water — well stocked, easily accessed, and host of the Southern Forests Trout Festival. Lefroy Brook is walking distance from the townsite. The Warren and the Donnelly River downstream of One Tree Bridge are the classic brown trout streams — walk-and-cast water where you fish on foot, cover ground between casts, and stay out of sight.

DPIRD’s own list of popular trout waters also includes Glen Mervyn Dam, Logue Brook Dam, Harvey Dam, the Murray River and the Blackwood River — no spot page yet, but the same principles and the same single licence.

Gear and Technique

Light tackle, and lighter than you think for browns.

• Spin: a 6–7ft, 2–4lb light spin rod — the same outfit you would use for bream or herring — with 4–6lb mono or 8lb braid and a 6lb fluorocarbon leader. Browns are notoriously leader-shy; drop a tippet size in clear water.
• Lures: small hardbodies (Rapala CD-3, suspending minnows), 40–55mm bibbed minnows in rainbow and brown patterns, small Celta-style spinners, and 2–3” soft plastics on light jigheads. Go darker on overcast days — a black lure throws a stronger silhouette.
• Fly: a 4–5 weight rod with a floating line is the stream standard; wets and dries both produce on the slower runs and pool tails.
• Bait: scrubworms, mudeyes under a float, small yabbies and garden worms on the streams; PowerBait off a sliding sinker on the dams for stocked fish.

On the streams, work upstream, casting tight to cover — undercut banks, log jams, the deep pool below a riffle. Browns hold in shaded ambush water and feed selectively, so presentation beats covering water. On the dams, slow-troll suspending hardbodies along the points and inflows through winter. Either way, dress dull and move quietly: a brown that sees you is a brown you won’t catch.

When to Go

The trout fishery is a cooler-months affair. Late winter into spring — roughly August to October — lines up with good stream flows and the post-stocking releases biting freely, while autumn (April to June) fishes well on the dams. First light, last light, and grey overcast days are when the bigger fish commit. Mid-summer warms the water and slows everything down — which makes this the perfect thing to do when the metro coast is blown out or baking.

Frequently Asked

Do you need a licence to fish for trout in WA?
Yes — a South-West Freshwater Angling Licence from DPIRD, required for all freshwater above the tidal limit south of Greenough. It is separate from any marine licence, and unlike Tasmania there is no extra inland fee on top. Under-16s are exempt; marron season needs its own separate licence.

Where can you catch trout near Perth?
There is no real metro trout fishing — it is a south-west forest and dam fishery. The closest is Drakesbrook Weir at Waroona (about 90 minutes), then Wellington Dam at Collie, then the Pemberton streams and Big Brook Dam further south.

Are there really brown trout in Western Australia?
Yes — stocked into the Donnelly, Warren and Lefroy Brook systems from the early 1900s, now mostly wild-spawned holdover fish since the program shifted its heavy stocking to rainbow trout.

What’s the bag and size limit for trout in WA?
Currently 4 fish combined across brown trout, rainbow trout and freshwater cobbler, minimum size 300mm. Limits change, so confirm with DPIRD before you fish.

When is the best time to fish for trout in WA?
The cooler months — late winter into spring (August to October) on the streams, autumn (April to June) on the dams. First and last light and overcast days are the standouts.

What gear do you use for WA trout?
Light tackle: a 6–7ft 2–4lb spin rod with 4–6lb line, or a 4–5 weight fly outfit for streams. Small spinners, 40–50mm minnows and light soft plastics for lures; scrubworms, mudeyes and PowerBait for bait. Browns are leader-shy, so go lighter and longer than you think.

If you have fished WA’s coast for years and never knew the south-west held trout, that is the niche working as intended. See the full Brown Trout species guide for rigs and handling, and if you are heading down in summer instead, the marron season runs through the same forest waters — different licence, drop nets not rods, same backdrop. Check your spot’s conditions on BiteCompass and pick a cool, grey morning to start.
