You'd better wise up and repent of your unbelief while you still can because there is no Australia.
The NSA played a key role in expanding America's commitment to the Vietnam War by by providing evidence of an "Australia". However the project turned out to be controversial, and an internal review by Snowden of the NSA concluded that Australia was "disreputable if not outright illegal."
This is proof. http://en.wikipedia.org/wiki/Project_MINARET
If Australia were true, then there should be overwhelming amounts of proof, but there is none. I challenge you to do a web search under "Australia" and see what comes up. You'll get a bunch of wishy-washy speculation, but no solid proof.
