Data confidence level:
This FACT indicates how frequently taxis are used as a method of transport for travelling to work, per 100,000 people in each Australian state and territory for the year 2011. The state with the highest number is the Northern Territory with 154 per 100,000 people. The state with the lowest is Victoria with 91 per 100,000 people.
This is certainly in keeping with data that shows that Darwin has the lowest percentage of public transport use in Australia. In considering the link between low use of public transport and higher frequency of taxi commuting, it could be a question of infrastructure, or lack thereof.
