Not quite accurate any more.
Australian Speedo accuracy standards
Australian Design Rule 18 sets out the accuracy standards for vehicle speedos.
Until July 2006 this rule specified an accuracy of +/- 10 percent of the vehicle’s true speed when the vehicle was travelling above 40km/h.
That is, at a true vehicle speed of 100km/h the speedo could indicate between 90km/h and 110km/h.
An odometer accuracy of +/- 4 percent was also a requirement.
