Been there and done that. Here's the low down.
-Your height and weight must be proportionate.
-You must be able to increase your heart rate all the way to 195 bpm on the treadmill while hooked up to the EKG machine (many avid runners have failed this test).
-They will put you up to an eye machine (sorry don't know the name of it) and you have to be able to see all 81 flashes, one eye at a time.
-They will hook you up to the EEG machine (brainwave test) and you'd better pass it. This one you can't really prepare for.
-567 questions MMPI-2 psych test and an interview with a shrink. Don't try to out smart him, he does it for a living.
-Basic physical examination and blood/ urine test (recommend getting a blood test at least 3 weeks prior to the exam and work on any item that's abnormal, i.e. high chlorestoral etc.
-Few other bits here and there such as hand strenght test, walk a straight line with your eyes closed etc.
Although it has been a while for me but that about sums it up. By the way, the above examination was done in Los Angeles but I don't expect it would be much more different in Sydney. Good luck.
