What Vic and NSW did was to stop accepting the ADR as a defence for speeding so you can be happily driving in one of those states with your speedo showing exactly 100kph but if you are actually travelling at 105kph because your speedo is (legally) reading slow you will get booked and you have no defence.
Also in Victoria at least the allowance is 3kph not 3%. If you are doing 53 in a 50 zone you are okay, 54 and it costs you $146.00, if you are doing 103 in a 100 zone okay but 104 costs you $146.00
Except you do have a defence, if you have you car tested to show that it's reading within the ADR's this is a valid defence. What you can't do is show up in court and claim your speedo can be + or - 10% and expect it to be accepted.
