Sadly I don't collect this species locally (if I did it would be at least a 3 day 12hrs of driving a day road trip - 2926km), I got these from a commercial fish/ shrimp/ plant producer in the Northern Territory. I am pretty sure if I did find any rednoses in my area they would be the C.gracilirostris. Mostly I tend to find a local species of glass shrimp and Macrobrachium.......although I have been furthering my local native snail collection of late.
