The map shows the population distribution in Australia. (From the graph, we can see) the vast land in central area has a quite low population density, (with less than 0.1 person per square kilometer) because it is mostly covered by deserts. Most people prefer to live along the coastal areas, especially the southeast and southwest areas (with 10 to 100 people per square kilometre). Sydney and Melbourne are the most densely-populated cities, with more than 100 people per square kilometre.
