Fishing is a great way to relax and enjoy the great outdoors. Perch, trout and marron can all be found in Collie’s dams and streams. Spend a relaxing afternoon on the riverbank, or try your luck catching marron (in season) with a bushman’s pole. There are plenty of spots along the Collie River, the shores of Wellington Dam and Glen Mervyn Dam where you’re bound to be lucky

 Fishing is not permitted at Harris Dam as this is a drinking water supply.

Licences for fishing and marroning are required and can be purchased at Fisheries Department offices or online at

Marron season is from 12 noon on the 8th January until 12 noon on the 5th February. Check the Fisheries Department’s website for bag and size limits and other regulations. Bag and size limits apply to trout, cobbler and marron, but not to red fin perch.

The Southwest Freshwater Open Season operates from the 1st September to the 30th June. Most waters are closed to all line fishing (ie fishing for redfin perch, trout and cobbler) from the 1st July to the 31st August.

Red fin perch make good eating and are easy to catch, with fishers using lures or worms as bait. As they’re considered a pest, any fish caught cannot be returned to the water.
