Hi @AmyKL thanks for the sighting. This is actually the other wallaby, the Red Necked Wallaby (Notamacropus rufogriseus), which is slightly less common in the area. The Swamp Wallaby (better named Black Wallaby) Wallabia bicolor, is darker overall with an all black tail, dark head, yellowish tinged fur on the chest. Have a look at the pictures here Other Shrubs or in the menu click Species; Mammals; Kangaroos.
