The Common Wallaroo has a large black rump it shares in common with all other Wallaroos.  The male is distinctly darker in colour in comparison to the female which is very grey in colouration with black markings.

They emerge at dusk to graze on grasses, shrubs, chenopods and herbs.

Breeding can occur at anytime of the year except in times of drought.  The gestation period is approximately 34 days with the joey continuing its development in the females pouch for around 261 days.

Inhabits escarpments and rocky hills from arid grasslands to coastal rainforests which provide shelter from the extremely high temperatures.
