...can't help you with the fish question but with that heading I thought there was a Robert Redford sighting around Collie...maybe he was there doing some horse whispering or something?

Sorry, sometimes the urge to be a smartass becomes too great for me...

Haven't fished Collie before so can't really help with location but worms have always been a favourable bait for me in the past. Redfin will take almost anything, have caught them on the small bladed spinners and small minnow lures. Never found them to be overly fussy to be honest. Best of luck!

 Anywhere I can get hold of some worms? Ahah my yard has nothing :p 

The golf course is on Mungalup road, I have never fished it but Minningup pool is just near there it is part of the Collie river and there is also a gravel track that runs along the river that takes you to Allanson and not far from Black Diamond. There are lots of spots around there (slow water and rapids) to stop and have a cast or have a swim.

There is also alot of tracks that run near the Brunswick river off Mornington rd but not sure what they are like at the moment or if they have been closed off havent been there for a while. Some of the best 4x4 tracks Ive ever done are also in this area.

As mentioned they dont seem too fussy and take most small lures and baits thrown at them just a matter of trial and error.

Hope this helps.

Growing up in Boddington, I used to just catch my worms near the riverbank if the soil was moist and not too compacted. Or raid someones compost heap....

Or if there are minnows in the Collie River, just bait a tiny hook with a piece of worm (or meat might work, not sure how fussy they are) and flick it out unweighted. We used to have a creek near town where we'd catch a heap of minnows like that and use them as live bait under a float. Officially the best bait for redfin in my opinion. Just a bit more work required but well worth the effort

 Apparently your not allowed to go fishing there at the moment! They are using some sort of poison to kill hyacinths or something along those lines! 

 find the galaxia minnows ( dont be confused with the gambusia or mosquito fish as they are often called) , normally in small schools around culvets and little calm pools with shade, use a net and send someone up the other end, be careful as they are spooked easy and are vey quick but they will always hold the school so if you give them some time you can try again, get the other person to wade through the water and scare them towards you, takes some well practised team work but they are the best bait going, just drop them down live on a small hook. i wouldnt be here tomorro if i told you the good spots around collie as the lads would have me head :) 

good luck with the red fin

other wise use cheese! cheese is hands down the best bait for everything in that area, caught most my trout from collie river on it and often have marron walking from everywhere to get to it

all the best
