All of the major areas in Canberra can be reached by public transport, with a fairly frequent service around the city. The airport is situated 7km Southeast of the centre, and offers a bus service to the city (Number 80), however, this service only runs on weekdays. Alternatively you can catch a taxi.
Buses in the city run fairly frequently, with interchange areas in the Civic being on Alinga Street, East Row and Mort Street. Canberra is split into 3 sections. It is possible to buy tickets for just one zone or all zones, obviously depending on where you want to travel. If you plan on travelling a lot during the day then the most economical ticket would probably be the 'all-day/all-zone' ticket. The service is by the Australian Capital Territory Internal Omnibus Network (ACTION). You can get more information from its kiosk, (corner Alinga Street and East Row), open until 11.30 every day or by calling Ph: (02) 6207 7611.
For transport around the main sights either take one of the ACTION buses or hop onto Murray's Canberra Explorer. The explorer travels to 18 different sights, where you can join or leave the service at any stop. You can either buy a single or a full circuit ticket, allowing you a two hour stop on the way.
There are taxi ranks at most major areas of the city, but to book a taxi call Canberra Cabs on Ph: (02) 6285 9222.
You can also get further travel information and contact numbers for the whole of ACT, from the ACT Travel Section.
