WOMBAT ON THE GOLD COAST

Unlike most other Australian marsupials, the wombat has a relatively large brain. This, combined with strong instincts upon maturity, allows a captive hand-raised wombat to be successfully released into the wild, unlike most other wild animals which either must be raised in specially simulated "wild" conditions (e.g., using "puppet parents") or kept as exhibits for their lifetimes.

Baby Wombats are truly cute and surprisingly heavy even when really small. They mature into not so cute 35kg powerhouses.

In their natural environment they live in maizes of burrows, when domesticated they will tunnel through anything to get to where they are going, via the shortest route possible.
As an example ; I raised a wombat [Bulldozer] and released him into the wild when he was mature. After about two months I heard a banging on our front door. when I opened the door  Bulldozer calmly walked in and crossed the room to the opposing wall and started to dig through it. Nothing I did to distract his digging worked. Finally after about ten minutes he was through the wall and continued on his journey to who knows where - leaving me to stare at a gapping hole in the outer wall of our house. The wall was constructed of mud brick 12" thick.
Four days later in the middle of the night, I awoke to the  banging against the panel we had placed over the hole in the wall. I got to the wall in time to see Bulldozer break through the panel and saunter to the front door. I quickly opened the front door to let him out before he rammed it.
Bulldozer occasionally repeated this pilgrimage for the next several years. Thankfully the new tenants were as nuts on animals as myself.

Wombats, like all the larger living marsupials, are part of the Diprotodontia. The ancestors of modern wombats evolved sometime between 55 and 26 million years ago. About 11 species flourished well into the ice ages. Among the several rhinoceros-sized Giant Wombat (Diprotodon) species was the largest marsupial to have ever lived.
The earliest human inhabitants of Australia arrived while diprotodons were still common. The Aborigines are believed to have brought about their extinction through hunting, habitat alteration, or probably both.
