All of Australia's major cities have reliable, affordable public bus networks, and there are suburban train lines in Sydney, Melbourne, Brisbane, Adelaide and Perth. Melbourne also has trams, Sydney and Brisbane have ferries and Sydney has a light-rail line.
All cities provide smartcard tickets. Users are able to keep, reload and reuse to pay for travel on public transport.
Depending on which city you arrive in when you reach Australia, you may be able to purchase one of these cards at ticket windows at the Domestic and/or International airport train stations. Depending on the city, you can also buy the cards at vending machines, 7-Eleven stores, newsagents, bus stations, train stations, ferry wharves, pharmacies, supermarkets and convenience stores.
