This huge bug was found and after taking a beating from a broom was still alive. It was greyish in colour on the back and a lot bigger but unfortunately after a degreaser bath seemed to shrink a little and change colour.

Toe-Biter
Giant Water Bugs like the one you “degreased” are commonly called Toe-Biters in North America. According to the Australian Museum, other common names include Electric Light Bug and Giant Fishkiller. A Queensland Museum pdf fact-sheet-water-bugs-water-scorpions indicates it is the largest true bug in Australia and that Toe-Biter is also an acceptable name down under.  Wannabee Entomologist has a fun posting.
