This enclosure is within a walk-through Australian area called Neighbours. There are free-roaming Eastern Grey Kangaroos, Parma and Tammar Wallabies, Emus, and Cape Barren Geese. Other separate enclosures contain Tasmanian Devil, Brolga, and Eastern Water Dragon.
It's sort of both. This area has been redeveloped from what were various individual enclosures, mostly by removing the fences and then landscaping (most of the area is for free-roaming animals). That's why there's such a wide concrete path.
Where the Dingo enclosure is now, there used to be a wallaby enclosure. The front of the enclosure is all brand new (the previous wallaby enclosure was just a mesh fence), although I'd imagine they removed all the fencing and started from scratch.
To the right of the photo (out of frame) is open and planted now but there used to be various cages which had housed species such as Snow Leopards, Servals, and Red Pandas at various times.
Behind me (i.e. behind the camera point-of-view) is where the Brolga enclosure is (where the Emu is sitting in one of the other photos).
If you were to walk away from the camera along the path, then further ahead you would find the Tasmanian Devil enclosure and then the path turns left up a slope where the planting is much heavier (this is where all the kangaroos and wallabies were resting out of the heat).
To take the photo of the Dingo enclosure I was standing approximately where the person with the umbrella is in the older photo, and facing to the left.
The current path actually looks much wider than it used to be, unless it is just the perspective of zooboy28's photo.
