Melbourne offers a great  tourist services, it used to be free however now they charge $5 for unlimited trip that get close to the main tourist sites in the city.  You can get on an off as you wish.


There is also free Tram service that is avaliable called City Circle Tram. They use older wooden tram cars for the most part, providing a special experience.  The route loops around the CBD, service goes in both directions. Stops are marked by a unique sign for the City Circle Tram (different than the regular tram service). There is recorded commentary describing the nearby sites. The CBD is small enough that nothing is more than a few minutes walk from a tram stop. For more information: click here and map.

The bus route goes to areas outside the CBD. Service is every 15 minutes, and it's very easy to use, and has a really good map handout.    Look for the red & white coloured bus stops. This link describes the route.
