Wombats are the largest burrowing mammals in Australia. These stocky creatures dig vast burrow systems of up to 20 metres long, more than two metres below the ground, with their rat-like front teeth and powerful claws. The rump of the wombat is covered by a very tough, thick skin that is often used as protection from attackers, as it dives into its burrow or a hollow log.

The Common Wombat, the species featured on the stamp, is the only living member of its genus Vombatus, though it is similar in appearance to Australia’s two other wombat species, the main difference being the absence of hair on its nose and courser fur. The Common Wombat’s main habitats are limited to south-eastern Australia.
