The fact Australia has so much available space really demonstrates how forward thinking Steve was in acquiring land for future expansion. Having heard the plans the zoo had in place for immense geographical precincts, it's such a shame this was never realised on the scale he envisioned.
One day, *hopefully*, there'll be an Irwin that wants to carry out Steve's visions. He obviously had such big plans for Australia, it's an incredible shame he died very early. Who knows what Australia could've been today if Steve was still around. I'm confident in saying Australia might have been one of the best zoos in the world.
