Data confidence level: 
This FACT indicates the population density of the CBD (Central Business District) in each Australian capital city. The CBD density of Australia's capital cities is constantly growing, as more people seek to live in the CBD, as well as inner-city suburbs. High-density living is influenced by many factors, including accommodation availability and infrastructure, but it is also an important factor for the development of new city infrastructure, including public spaces and public transport services.
The Australian city with the highest population density is Sydney, with 8391.1 people per square kilometre. The least dense is Darwin, at 755.5 people per square kilometre.
*NOTE: CBD-specific data could not be found for Canberra and Hobart.
