In the meantime there are a variety of good forums spread around Australia where weather enthusiasts and storm chasers come together and they are usually good places to learn as well. The most obvious national one is the Weatherzone forums but some people don't like their level of moderation. But on the other hand each state seems to have their own independant forum. Here in WA I'm part of the WAWeathergroup forums but you might want to have a look at the
Brisbane Storm Chasers Page (hmm, they don't have a forum, but they do have great predictive charts!) The
Australian Weather Forum also has a good reputation.
Just for fun is the
Cloud Appreciation Society as well.
