Ok, explain, wallabies are smaller, cute cuddly and tend to live amongst sheltered areas, like trees and rocks. Roos can reach up to 2 metres plus and tend to live in open grasslands.

Roos are also a pest and in overwhelming numbers, well above the normal 'natural' numbers, so have been shot for dog meat, until it was realised just how lean and healthy the meat was. Farmers sunk bores for cattle water, the roos liked that and the extra grass, and bred like crazy - they can have three on the go at once, one at foot, one in pouch, and one in uterus in stasis, waiting for rain, so they can restart this one real fast.
