No reward for this CarbonAI. JohnGiacon you were right to change your mind to suspect not Black (Swamp) Wallaby. The strongly tapered thick tail says kangaroo, not wallaby, and for local wallabies, so does the absence of a cheek stripe. There are two local kangaroos and this is the less common one, ie the Common (Eastern) Wallaroo, or Hill Kangaroo, Osphranter robustus. The males have this dark grey fur on the flanks and and back. Females are very pale grey with white tails.
