Australia is the world’s sixth largest nation.
Even so, fewer than 15 million people live in this vast country. The average population density of Australia is just 4.8 persons per square mile, one of the lowest on earth.
Most Australians live in settlements that are far more crowded than the nation’s population density suggests. About 85 percent of Australia’s population lives in cities or towns.
The percentage of people who live in cities of more than 50,000 people is 77 percent, the highest on earth. In fact, more than half of all Australians live in just 5 cities, Sydney, Melbourne, Brisbane, Adelaide, and Perth!
