Dubbo isn't wombat territory, and the zoo hasn't lost their's. We don't know where it came from or, as I write, where it is. I'm on the rescue phones at the moment, waiting for a cry of help from someone being menaced by this rampaging beast.
I wonder if Digger made another wrong turn.
EDIT: Looks like the wombat is headed back across the river to the West Dubbo Bowling Club greens.
