If you break the speed limits in Perth, there is a good chance you will be caught. There are many speed cameras and traps in the city and its suburbs. Random breath tests to catch drunk drivers are also common.

During business hours, public transport in Perth offers efficient, inexpensive services. Transperth tickets are sold on the basis of city zones and can be used to travel on both buses and trains. You can buy Transperth tickets in most newsagents.
If you will be making a journey regularly, you should buy a MultiRider ticket. These work out 15 percent cheaper for 10 journeys and 25 percent cheaper for 40 journeys than the standard fare.
Perth's public transport system is good for getting you into the central city and out again but is less useful for travelling between suburbs, for which a car is strongly advised.
In the central city, a free bus service, the CAT, is very handy.
