Found this clip of the building of a breeding enclosure for Brush-tailed rock wallabies on the web althrough I had never heared before of "Aussie Ark ". Somebody else with more info about this place ? : https://www.facebook.com/video.php?v=1008254889366735
Aussie Ark grew out of Devil Ark which itself is owned by the Australian Reptile Park as part of their participation in the Devil Insurance Program.

I only found out recently that Marsupials in more temperate regions of Australia that experience snowfall e.g. Tasmania, do not grow a winter coat and then moult it again- they don't moult at all but rather raise the guard hairs of the coat in winter to provide insulation, giving them a thicker-furred appearance.
