Seen some truely HUGE fish taken out of the river here (clarence) on a regular basis. Saw a 7.9kg fish a week and a bit ago that was the 9th fish for that bloke in a week over 6kg. All released bar one which was hooked in the gills and was bleeding profusely.
Edit: I know a bloke who has told me he has pictures of a 3 1m+ flathead. Ill try and get them to put on the net. they're back in the dark age (film)
