Not very old, certainly. Several years ago at Birdland animal park in Batemans Bay (NSW south coast) I was lucky enough to meet George, a baby wombat being hand-raised after his mum was killed on the road. He was ugly/cute, nearly hairless with big ears. I have the pics to prove it.

Wombat doesn't mean waste of money, brains and time, you know.....despite what some people say.
