Speed limits in Australia range from 5 km/h (3.1 mph) shared zones to 130 km/h (81 mph). Speed limit signage is in km/h since metrication on 1 July 1974. All speed limits, with the sole exception of the South Australian school and roadworks zones, which are signposted at 25 km/h, are multiples of 10 km/h – the last digit in all speed signs is zero.
Australia closely follows the United States when it comes to road sign designing practices (for example, using yellow diamonds for warning signs and green direction signs), but some types of road signs in Australia, such as road signs for speed limits, roadworks, "reduce speed" signs, and chevron arrow-styled direction signs are influenced by ...
