This stamp issue features four species of some of the most popular Australian marsupials and their young. Marsupials are mammals that are distinguished by their particular reproductive cycle. Most female marsupials have pouches in which the young develop after spending only a short time in the mother's uterus. After birth the embryo-like offspring climbs into the mother's pouch using strong front limbs, where it remains, attached to a teat, until mature enough for independence. The four marsupials, namely the bush babies, featured in this stamp issue are the Koala (AU$1.45), Eastern Grey Kangaroo (AU$2.10), Brushtail Possum (AU$2.90) and the Common Wombat (AU$4.20).
