What's That Bug? does not endorse extermination

While walking through the Fern Tree Gully reserve in Australia, we came across a strange bug. It looked like it was trying to burrow down into the soil.
There was a creek near by, so we also wondered if it was some kind of crab/lobster type bug that perhaps a bird had just picked up and dropped?
Never seen anything like it. Hopefully you can help identify!
Thanks a lot

Dear Jason,
This is a Crayfish, an aquatic, freshwater Crustacean that burrows into the mud and is able to survive periods of drought underground.  It appears that this Crayfish is missing its front claws, however, they are able to regenerate.  According to Encyclopedia Britannica:  “Lobsters and crayfish regenerate claws and legs in a straightforward manner as direct outgrowths from the stumps. As in other crustaceans, however, these regenerates lie immobile within an enveloping cuticle and do not become functional until their sheath is shed at the next molt.”

    Just looking through the archives for fun, and I had to find out what this unusual crustacean was. This looks a lot like the endangered Warragul burrowing crayfish. http://theconversation.com/australian-endangered-species-victorian-burrowing-crayfish-19658
    Poor thing lost its claws.
