Back in the days when I was still a wage slave, I would do Singapore->Brisbane->Sydney->Melbourne->Adelaide->Perth->Singapore in a week. I'd just do meetings wherever there was an oil refinery and spend the rest of the time in taxis, hotels and being shuttled around by Ansett. I did that on and off for three years. My last ever trip in 1990 was a holiday before I returned to the UK. We did Darwin, Kakadu, drive down the Stewart Highway to Alice, do The Rock and then fly to Cairns for the reef. Brilliant! In all that time I never once saw snow! Are you sure you didn't Photoshop that picture??
