The public transport system in Adelaide is divided into 3 parts.
- Tram
- Buses plus the O-Bahn system
- Trains
Buying Tickets
To buy a ticket for the tram, train or bus system (you use the same tickets for all systems) you need to buy it from a newsagent where you see the Adelaide Metro sign or at the Adelaide Train Station.
You can also buy a single ticket on buses but quite often drivers will have limited amounts of change.
The Metro Pass most useful to visitors is a 3 day Metro Card – cost at time of writing $25 but increases every year. There is also a one day ticket which costs $10.60. You will probably only need this if you are planning to travel outside the CBD area. If you are staying longer, 14 day and 28 day options are available. This allows unlimited travel on all tram, buses and trains in the metro area.

Adelaide Trams
The tram system is the most likely public transport you will use in Adelaide. This is because it is used in the CBD area and connects areas that travellers will want to go.
The first thing you need to know about the tram system is it is free if you do not go past the stop -South Terrace on the Glenelg line. So if you want to go to Glenelg from the city or any of the southern suburbs you will need to buy a ticket.

Adelaide Buses
Its fairly unlikely you will use the buses that much however it is worth knowing that there is a bus that goes to the Adelaide International Airport that you can pick up on Grenfell and Currie Streets. The bus number is either J1 or J2 (subject to change) so check beforehand.
The other 2 places you may want to go that are only served by buses is St Kilda Tramway Museum Bus 401 from the city. Mount Lofty Botanical Gardens you need to take the bus to Crafers and then another bus to the gardens (only 4 buses per day). Make sure you validate your ticket on the machine when you enter.
There is also an O-Bahn service into the north eastern suburbs that finishes at Tea Tree Plaza shopping centre.
