How large are the koalas' litters?

The home range of a koala may be as small as 0.01 square kilometres in thickly-bushed areas of Victoria. In central Queensland, however, the koalas' home ranges have been found to average 1.35 sq km for males and one sq km for females. Within this area, which overlaps with the home range of other koalas, each koala will regularly move from tree to tree, in search of food.
