Well...Australia is a big place, and I don't know where you might be located along latitude 32 degrees South. There are a number of factors influencing winds in addition to weather patterns, including local geography and terrain. Try posing your question to someone at the Austrailian Bureau of Meteorology. They'll know a lot more about the variations at your particular location. Good luck.
