Additional photo of this wallaby. It looks like it may be a female as there looks like dark small legs under it belly and there looks like a bulge between its back legs - perhaps a joey in its pouch?
It may be my incompetence at using the NaturMapr functionality but I currently cannot find any earlier or other record on the system of another sighting of Swamp Wallabies on Tuggeranong Hill. As I see one or two swamp wallabies almost every morning when I go for an early stroll I find this surprising. On the other hand, they seem very cautious, almost furtive, and much more inclined to hop away than either of the other two local macropod species, so I have found them difficult to capture in a photograph. I also remember one visiting my garden (which abuts Tuggeranong Hill) in the drought of the early 1990s. This may indicate they have been present for some years, though I am sure their abundance has always been well below that of Eastern Greys or Red-necked Wallabies.
