I like to think I'm a bit of an expert on Australia; I first visited when I was seven years old, and then spent a few weeks almost every year here (with two years living in Perth and going to high school there at age 16/17), before I eventually moved back in October 2016. I also spend almost eight hours a day embedded in the Tourism Australia website due to my day job, so am at the point now where I can comfortably provide a full 'ultimate' guide to spending two-weeks in Australia. And no, you don't need an entire month to visit - you really can see a lot within just two weeks!
