Yep That's along tailed weasel and they are indigenous to this area, I saw five of them in one day while mowing my field earlier this year, they live in the squirrel burrows and are quite vicious, ever seen a squirrel with a short tail? these guys are the reason why!
There like a miniature wolverine, I had a family of them living in my back yard until my two Queensland healers ate them for lunch, I saw one carry off a rabbit that was twice his size. Bad ass they are! Cool pic D!
