Meaning
Any of three closely related species of moderately large macropods, intermediate in size between the kangaroos and the wallabies.
Etymology
Origin: Unknown
Borrowed from Dharug walaru. Not, in fact, a blend of wallaby and kangaroo, although the fact that wallaroos are between wallabies and kangaroos in size may lead to that assumption.
