I think the fountain and a facepalm mean different things. I can picture a world where both exist in harmony.
On topic, yeah the train is gross. If you think the train at Aussie World is better themed than the same ride at MW I suggest you don't know what themeing is. The trains at Currimbin sanctuary are at least themed to look like different famous Australian trains, this looks like nothing. It's bright and garish and in no way reinforces the 'Aussie' theme of the park. It looks like its painted in such a way that it'll stand out on the midway of the Ekka.
But for an off the shelf design with nothing customized on it; the landscaping is nice, and while the design is gross the paint isn't faded and everything looks like it's in good condition. If Dreamworld or anyone building a real theme park added that I'd be slamming it. But for a small park like Aussie World, I actually don't have a problem with it. Aussie World is a collection of nicely presented carnival rides, not a theme park, and so this fits in with that pretty well.
But yeah Movie World has the same ride and themed it to the world of Yosemite Sam. That's themeing.
