That's according to Vic Roads.
I called them today (15/4).
From the 15th of December, if you exeed the speed limit by 15kph or more, you can lose your license for at least 1 month.
If you are found driving under the influence, you will lose your license on the spot.
You don't belive me, call them on 13 11 71, choose an option and wait on their queue.
