Common wombat, vombatus ursinas.

Wombats are formidable diggers. They are the largest burrowing animal in the world and can construct tunnels over 30 metres (100 feet) long. They are powerfully built with strong foreclaws and large incisors which they use for biting through any roots that might be obstructing the path of the burrow.
Wombats suffer greatly at the hands of man. They die as a result of diseases introduced by cats, are attacked by cats, dogs and dingoes, are often hit by cars and are facing reductions in habitat.
The Northern Hairy Nosed Wombat is now critically endangered with only about 70 individuals left.
This  common wombat was photographed near Cradle Mountain National Park in Tasmania.
