Public transport is a vital part of Canberra's transport scene. As well as posts on this blog on public transport, I also maintain a website for ACT Light Rail.
ACT Light Rail website is here (Community based lobby group).
You might also enjoy ACTBus (Community based bus enthusiast group).
ACTION Buses has its own website. (ACT Government website).
Capital Metro has one as well(ACT Government website).
