Hmmm... Thank you for the link; I will sure check it out.Diamondhitch;1612852; said:Nope, Cherax Quadricarinatus. Because of the wide variations in color of both species, it is possible it is a C. Destructor but I would lean strongly toward a female C. Quadricarinatus (females dont actualy get the red strip on the claw that they are named for).
Here is a good link showing both.

If nothing else time will tell for sure because C. Quadricarinatus get twice as big as C. Destructor and grow much faster.
Either way, nice cray.
