Last week I was attending the World Computer Congress 2010 in Brisbane to talk on sustainable IT issues. So public transport seemed the appropriate "green" way to get there. But I was surprised to find that the quickest way to get from where I was staying near University of Queensland to the Brisbane Convention & Exhibition Centre was a 20 minute ferry ride.
There are ferries down the river from University Of Qld to South Bank about every 20 minutes during the day. The CityCat catamaran ferries are fast and comfortable. The same go card electronic tickets work on the ferries as on buses, but there is also a person to buy paper tickets from on board and to give tourist information.
Most commuters sit inside in the air-conditioning. But a bonus for tourists in fine weather is the open deck at the bow of the vessel, with panoramic views of the city.
There is also WiFi on board for University of Queensland staff and students. The university is part of the EduRoam network, but I was unable to get my ANU EduRoam account to work.
