Hi jac, thanks, based on that I think it is a rodent. The possibilities at that location are Rattus rattus (introduced Black Rat or Roof Rat) in the first several places, then Rattus fuscipes (native bush Rat) a long way back, and finally Rattus norvegicus (introduced Brown Rat or Sewer Rat) but quite unlikely. So I put it down as R. rattus.
I had not seen your posts of the pig and the possum.
