crazydingo,
i just contacted my local raaf base (east sale) saying that i was interested in becoming a pilot and would like to come down and talk to some of the pilots and have a look around, got a email back, talked to someone down there who helped me arrange it. (and CFS is extreamly busy)
so i would just contact the base directly, call 1800 033 200 and ask to speak to the base of your choosing.
hope this helps
