Designed as a gardening shed, because the theme of this area appears to be suburban animals?
This enclosure is in a walk-through Australian area called Neighbours, with free-roaming Eastern Grey Kangaroos, Parma and Tammar Wallabies, Emus, and Cape Barren Geese. Other separate enclosures contain Tasmanian Devil, Dingo, and Brolga.
Thanks for all of the photos! These kind of exhibits are always slightly controversial with zoo enthusiasts because there is obviously no attempt at creating a natural-looking environment for the species being showcased. On the other hand, are Eastern Water Dragons commonly found in gardening sheds? I can recall staying at a motel in Cairns, Queensland, and seeing water dragons by the side of the pool and hanging around the motel's pool shed; perhaps this zoo enclosure has a large dose of truth to it.
