This is a Monjon, the smallest rock-wallaby, only found in a few select locations in the North-west Kimberley, including the Mitchell Plateau. Check out the joey in its pouch.
"The species retires to caves and cavities amongst the sandstone. The diet is primarily composed of grasses and ferns. The breeding period is assumed to be year round, with most births occuring during the northern wet season. The Monjon is listed as near threatened, partly because of the small size of its known range".
