According to the Australian Bureau of Statistics - www.abs.gov.au - 64% of the Australian population is located in capital cities. The most populous capital city is Sydney (capital of New South Wales) followed by Melbourne (capital of Victoria).
The major of people in Australia live on the coast. The population density drops quite significantly when moving inland.
South East and coastal
The Commonwealth of Australia has a population of 23,535,807. The population density is 7.3 people per square mile. The population of the Australian continent is 36,000,000, and has a population density of 11 people per square mile.
According to the Population Reference Bureau, in 2011 (the most recent figures), Australia's population density was 3 people per square kilometre.
2.91 people per sq km, with a total population of 22,328,800 people.
Yes
Mining is mostly concentrated in WA (Western Australia). This is because of its low population density and abundance of raw minerals.
Australia.
Not at all. The majority of Australia's population is concentrated along the eastern and southern coasts, leaving vast areas of the continent virtually uninhabited. Because of this, Australia's population density is about 3 people per square kilometre, one of the lowest in the world. As a comparison, the population density of the United States is about 34 people per square kilometre, while in the United kingdom it is 259 people per square kilometre. See the related link below for more population density statistics.
Although Australia has a low population density and a relatively small population of about 22 million, most of the country is inhospitable desert, so most people tend to live in the small temperate areas along some of the coast. There is also not much water in Australia so much of the country is under water restrictions. There is a school of thought that due to Australia's climate, the long term maximum sustainable population levels should revert to World War 2 levels of 9 to 10 million.
I have no clue maybe between 100 and 200 people per square mile.
Western Australia
Antarctica has the lowest population density of any continent. It has no permanent residents, and the population consists only of temporary researchers and scientists, resulting in a near-zero population density.
