In these modern times, it's possible for practically every buffoon out there to propose idiotic theories, spread imbecilic nonsense and to make laughably inaccurate, thoroughly absurd claims. That doesn't mean we have to pay them any attention. Whether the Earth is shaped like a sphere or a disc or a prism, it wouldn't negate the very undeniable and easily verifiable fact that Australia exists. Millions of people live there, millions of people lived there at one time or another in the past, and millions of people have visited. Not to mention that Australia is a unique place where humanity has had a continuous presence for over 40,000 years, geologically it's probably the oldest continent, and its flora and fauna are unique. It's an immense and highly varied part of the world and it boasts a rich and colourful history. It's also staggeringly beautiful and the people - both the indigenous inhabitants and the modern society, are definitely one of a kind. Trust me, it's there.
