For some reason a message about this record came back into my email today.
Very well done on all counts Kevin - good photos for ID and frozen carcass. For this species, the only person I can think of who might want the carcass is Leo Joseph at National Wildlife Collection. Prob his email is Leo.Joseph@csiro.au. Against the chance that you one day photograph some other mammal that is harder to ID, other things to photograph if possible could be (i) a view showing the inside of the ears (useful for distinguishing greater glider from yellow bellied glider), the head profile (for squirrel glider V Kreffts) and the teeth (if possible).
