This is totally going to turn into a **** fight, but I'll pitch in before closing time.
You always got suspended for 30+ over. From your own link:
Pre 1 July 2009: 31 to 45 km/h = 4 points, $621, 3 months suspension (min)
Take the time to actually read and absorb the information on that site. You'll actually find that the fines are almost exactly the same, and the demerits are much fairer to people caught low-range speeding.
You need some serious attitude adjustment mate, like Stressball said it's a privilege you have a license to drive on the road. If you don't have enough respect for your fellow motorists to stick to the rules (which are there for everyone's good, not just you) - then do us all a favour and catch the bus.
