Also known as the Eastern Short-eared Rock Wallaby. This is a medium sized wallaby at about 75-100cmlong and weighing in around the 2.6 to 3.5kg range. Mainly a med to dark grey body with reddish limbs, tail and face. The diagnostic black crescent behind the shoulder with a white border behind that. It also has a line of black running from its snout over the head and nape finishing between the shoulders. The tail is long with a bushy tip.
Found in sandstone country in Kakadu National Park near Ubirr. This species is quite restricted in range. Once thought to be a sub species of the Short-eared Rock Wallaby (Petrogale brachyotis), it has now been designated as a species in its own right.
Toward the end of 2014 it was confirmed through genetic analysis that this was a stand alone species. It is both smaller and generally more clearly marked to look at. Named after Captain Sir G H Wilkins who first collected this species in 1925. It took nearly 100 years to actually identify it as a separate species. The point being that although we take a lot for granted there are more species out there to be discovered and perhaps lost without even realizing it. Ref: Australian Museum.
