Fishing in Kosciuszko National Park

Kosciuszko National Park covers the high country of southern New South Wales, running from the alpine peaks around Mount Kosciuszko down through the river valleys that feed the Murray-Darling system.

It is the largest national park in NSW, and water is central to it — snowmelt and rainfall draining off the ranges into rivers, creeks, and reservoirs that hold some of the most significant trout fishing in Australia. The fishing here is almost entirely trout.

Brown trout and rainbow trout are the target species across the park's streams and impoundments. The season runs from the October long weekend through to the June long weekend, when the rivers close for winter.

That window shapes everything — spring through autumn, with summer bringing terrestrial hatches and autumn pushing large browns upstream on their spawning migration.

The Thredbo River is one of the most accessible waters in the park, running through the Thredbo-Perisher area and fished heavily by both wading anglers and guided clients.

The upper Snowy River near Charlotte's Pass is higher and more remote, a classic freestone stream suited to sight fishing and dry fly work.

The Murrumbidgee, Tumut, and Tooma rivers drain the western slopes and offer a different character — bigger water in places, with more room to move. The Geehi River and Swampy Plain River are quieter options further into the backcountry.

For reservoir fishing, Blowering sits at the lower end of the park's range and holds fish year-round under state rules, while Lake Jindabyne is the main impoundment near the eastern edge. Access varies considerably.

Some waters are roadside; others require a walk of several hours to reach the better stretches. The park charges a vehicle entry fee during the winter peak season, and anglers need a valid NSW recreational fishing licence.

Check current park alerts before heading in — roads and trails can close with little notice due to weather or management requirements. The backcountry streams reward the effort.

Spring dun hatches, summer hoppers, autumn browns — the fishing follows the season honestly here, and the water tells you where you are in it.
