Wallaby ID? Red-necked Wallaby?

It seemed a bit big and not quite right for Red-necked though. Maybe Whiptail, with such a white tail?

Whiptail or Pretty-faced Wallaby (Notamacropus parryi)

Hmm... that's the other possibility I thought of at first, but have you seen the associated discussion in this thread: http://www.zoochat.com/1415/macropod-species-452794/
