This is great for koalas....for guests though??
They need to think of the bigger pictures, parks that are successful with this kind of wildlife conservation area, for example Ocean Park Hong Kong (bar all controversy, just the first park that came to mind), do well because they offer both wildlife experiences and a heck of a lotta rides!
Just my opinion but I think this would fair better at places like Australia Zoo or Lone Pine Sanctuary where the animal experience is the experience! Or Dreamworld could you know, open some rides, say Sky Voyager and bring the public back with two new exciting things, a ride and a wildlife area. But I'm probably being too negative so ignore me!!
