How to buy a wombat?

Excuse me, could you please elaborate on the process of acquiring a wombat? I understand that they are not typically sold as commodities in the traditional sense, but I'm curious about the steps one might take if they were interested in purchasing one. Are there any specific breeders or sanctuaries that specialize in wombat adoption or sales? And are there any legal considerations or restrictions that one should be aware of before embarking on such an endeavor? I would greatly appreciate any insight you can provide on this unusual yet intriguing topic.
