Thousands of Aussies set to lose license, speed cameras to blame {Autoblog}

Also keep in mind that the legal requirement for the tolerance for the speedo is 10%, so while your speedo may say 100km you could be doing 110km and legally there is nothing wrong with your car. Of course that is no excuse as it is 'your responsibility' to keep in the speed limit.
