Now that's a true waste of space. Who needs a "cultural garden" when there could easily have been an animal exhibit there. Weren't there animals here (usually various primates) for more than a century?
@snowleopard I think due to it being heritage-listed, there wasn't much that could have been done as far as adapting the space drastically to maximize animal welfare. I wouldn't mind that enclosure housing stuff like brush-tailed bettong or juvenile perenties...
