Australia is a very advanced and technologically aware country and it's got a lot of intelligent companies, agencies, people and technology all coming together (just like the USA, UK, Germany, France, Turkey, Iran, South Korea, China) that list is pretty much endless and the less the restrictions the more advanced and extraordinary the technology is coming out. The more space becomes the focus of tensions, the more space becomes a attractive proposition for putting weapons the more space becomes a place where people, machinery and weapons will all need moving around. It will all need a place to sit it out when we're not killing each other. The more we will see strange aerial vehicles of the silent, wonderful, exotic and extremely Alien looking variety. These are the ones which was unlucky and was spotted. I'm sure that the Aliens in charge or the people in charge will be giving someone or something a very stern talking to. TR3B's exist, Alien UFOs exist and there's a grey area in between of who owns what and who is doing what and when.
