Brown trout in Australia

The wild trout of the highland rivers and Tasmania's lakes. Spawns in autumn, hence the closed rivers through winter in NSW and Victoria. Streams from October to June in NSW and from September to June in Victoria; lakes open all year; Tasmania from the first Saturday of August. Best month across the Australia waters we cover: April.

Identification and biology

The brown trout, Salmo trutta, came to Australia through Tasmania: the Inland Fisheries Service records that the first brown trout introduced to the southern hemisphere were hatched at the Salmon Ponds on the Plenty River, a tributary of the Derwent, in 1864, and released into the wild the following year, and that the Derwent still holds a wild population maintained by natural recruitment. On the mainland it breeds in the wild in cold, gravel-bottomed streams and lives in the lakes they feed, and New South Wales also stocks it from the Gaden hatchery. It is bronze to olive with black and red spots, a square tail and a wariness that grows with size, and it runs up the inflowing creeks to spawn in the cooler months, the same stretch of the year when the streams of New South Wales and Victoria are closed and the Tasmanian season ends. Big browns are old, and the biggest come from the lakes at night and in the cold months.

Where they live through the year

In Tasmania the brown trout waters open on the first Saturday of August and close on the Sunday nearest 30 April, and the plateau lakes fish from the early-season lure and bait fishing along the edges at Arthurs and Great Lake, and fly fishing only at Penstock and Little Pine lagoons, through the spring dun hatches and the summer mayfly into the autumn drop-offs. Most lowland rivers keep the same season, but the lower South Esk, Macquarie and Meander stay open to the Sunday nearest 31 May, the Derwent below the New Norfolk Bridge is open all year, and designated rainbow waters such as Dee Lagoon run from October to May. In New South Wales and Victoria the browns of Eucumbene, Jindabyne, Eildon and Dartmouth are along the edges in autumn and spring and deep in summer, and the streams are open from spring to the June long weekend. Everywhere the biggest browns are taken at night, along the edges, on bait and slow-rolled lures in the cooler months.

The mistakes that cost fish

Fishing the rivers in the closed season, computed for this year on the state hubs; and fishing a Tasmanian water outside the dates the Inland Fishing Code sets for it, because the waters differ. Fishing too heavy and too visible in clear water, where a brown inspects the lure and turns away; a lighter leader and a longer cast fix more slow days than a lure change. Ignoring the wind on the plateau, which makes its own weather and can turn a lake dangerous in an hour. And missing the night: the best browns of the Snowy lakes are caught after dark along the edges on bait and on slowly worked lures.

Reading the report for brown trout

The water temperature estimate and the calendar show the cool-water edge seasons and the deep summer; the wind row is the number to respect on the plateau and the Snowy lakes; the level chart on the gauged lakes shows the rising water that floods new ground where the browns feed and the low water that pushes them to the drop-offs. The species card rates the month; the season line on each water says open or closed today, from the rule the agency wrote.

Playbook by water temperature

The plan the daily report picks for brown trout in each band; the water temperature on each page is a seasonal estimate for its type of water and says so.

Hot water (over 27 °C)

Dawn at the lake edges and the cold inflows; the rivers at first light only.

Warm water (18 to 27 °C)

Early and late with flies and small lures along the weed edges and the river runs.

Cool water (10 to 18 °C)

Prime. Nymphs and streamers on the rivers, and the lake edges on the overcast days.

Cold water (under 10 °C)

The lake fishery: bait or slow lures in the deeper bays; the rivers are closed in NSW and Victoria.

Common questions

When does the Tasmanian trout season open?

The brown trout waters open on the first Saturday of August and close on the Sunday nearest 30 April; for 2026-27 that is Saturday 1 August 2026 to Sunday 2 May 2027, as the Inland Fisheries Service publishes. Some waters, Great Lake among them, are open all year.

Where were brown trout first introduced in Australia?

Tasmania: the Inland Fisheries Service records that the first brown trout in the southern hemisphere were hatched at the Salmon Ponds on the Plenty River, a tributary of the Derwent, in 1864 and released the following year.

What is the best way to catch a big brown trout?

At night along the lake edges in the cooler months with bait or a slowly worked lure, or at first light along the drop-offs; in the rivers, a nymph or a dry fly in the open season.
