Argument the dependence of the population density in Australia on various factors?

Australia’s population density depends on the following factors:
Natural and geographical. Most of the country’s territory has no population, there are deserts, mountains, reserves. That is why almost all the population is concentrated on the coast (southwest near Petra, Tasmania, southeast, east). The climate there is unpleasant for life.
Historical. The country was inhabited by migrants, they all came to coastal cities, for example, to Sydney.
Socio-economic. The population mainly lives in the major cities of the coast (Perth. Sydney, Brisbane).
