Get it? A-maze-ing find. Because it's a maze, right, and somebody found it! Alright, that's enough laughter for today. Let's get serious and talk about how this circular labyrinth got to be where it is. Someone making it is the obvious answer, except for the fact that it was discovered on a highly remote stretch of Australian beach, where nobody ever really goes.
So if it was by human hand, then they must have done it without ever thinking someone would find it. Which sounds a bit iffy to us - why would you build a maze that no-one else can play? It's not like it's much fun to do your own maze. The other option is, of course, that what we've got here is something like the Nazca lines. Which isn't any less spooky.
