Best time of year for Oz is September. If you are up north, humidity is still low, no threat of cyclones and weather still stable. If you are down south, westerlies (Sydney) should have gone, warmer temps than winter, relatively little rain. That is why the 2000 Olympics were held in Sept.. .As others have said, Oz is a big place. If the wx is crappy in one place, chances are it is beaut in another. If you have bought your ticket wisely you should have a couple of internal transfers you can use.
