What is the total population of Australia

The first traces of settlement in Australia are around 120,000 years old. At that time only Aborigines, the indigenous people, populated the continent. Europeans did not settle there until much later. European settlement began in 1788. 1788 was also the year in which the city of Sydney (4.5 million inhabitants) was founded. The capital of Australia is the planned city of Canberra (350,000 inhabitants), located somewhat inland.
Australia has a total population of around 22 million people. However, the total population density is just 2.7 inhabitants per km². Although Australia is over 21 times larger than Germany in terms of area, the country has only a quarter of Germany's population.

The cities as a crowd puller
The southeast coast is the most densely populated region on the continent. The cities of Sydney, Brisbane (1.8 million inhabitants), Newcastle and Melbourne (3.6 million inhabitants) are also located there. This means that three of the largest cities in Australia are located on the south-east coast. In the metropolitan area, the population density is 10 to 100 inhabitants per km². In the entire southeast and on the east coast there are predominantly 1 to 10 inhabitants per km². This area covers the area between the city of Adelaide on the south coast and Cairns in the northeast. There is only a similarly high population density on the southwest coast. There the population is concentrated in the cities of Perth (1.5 million inhabitants) and the smaller city of Albany with less than 100,000 inhabitants.

Big continent, few inhabitants
On the rest of the continent, the population density is less than 1 inhabitant per km². This means that a large part of the country's area is almost uninhabited. There are only a few settlements there, in particular due to the low annual rainfall and extensive arid areas (deserts). The only major cities are Alice Springs in the center of the country and Mount Isa in the northeast.
Thus, the settlement is limited to the coastal regions, where most of the large cities can be found. For this reason, one speaks of a high degree of urbanization (degree of urbanization) in Australia.
