You could try Macrossin. Just head to Charters Towers. Just before you go over Macrossin bridge (over the Burdekin) there is a camping area to the left. Park in there and take a walk downstream. Look for the deeper holes. I have not been there for a while, but always get a sootie or two. Fishability depends a lot on the water level. You may need to wade a bit.
