Are There Speed Limits in Australia?
Speed limits are heavily enforced in Australia specifically around peak holiday and travel periods like Christmas and Easter celebrations. Typically, speed limits range from 10 kilometres per hour shared zones to 110 kilometres per hour. In the Northern Territory four highways have 130 kilometres per hour (81 mph) zones. Speed limit signage is measured in kilometres per hour (km/h).
Note that the speed limit on a section of road may be varied from the above default speed limits by speed limit signs. All residential zones are 50 km/h unless signed otherwise. Maintaining a speed of 50 km/h if you are uncertain of the speed limit is hereby encouraged. Suburbs and across towns have a speed limit of 60 km/h or higher. School zones, usually have speed limits of 40 km/ during school hours and these are clearly signposted.
The maximum default speed limit in built-up areas is 50 km/h. Built-up areas include main roads, industrial and commerce districts. All major roads including freeways and/or motorways are clearly signed. For more information on speed limits, click here.
