What Affects the Population Distribution of Australia?

Question

Why are area sparsely and densely populated??

Answer 1

The interior is largely inhabitable with scare water and barren land. The coast is temperate and water is much easier to obtain.
Also, the convenience of ports for exchange and transportation because the interior is difficult to negotiate. Less difficult nowadays, but highways through the interior are relatively recent.

Answer 2

Vast areas of Australia are isolated and very, very dry. These parts of Australia are sparsely populated. More heavily populated areas are on the coasts.

Answer 3

Most of Australia's population is concentrated in two widely separated coastal regions. By far the largest of these, in terms of area and population, lies in the south-east and east. The smaller of the two regions is in the south-west of the continent. In both coastal regions the population is concentrated in urban centres, particularly the state and territory capital cities.

Australia's population density at June 2001 was 2.5 people per square kilometre. The highest population density was in inner areas adjacent to city centres, such as Sydney (C) - Remainder (8,400 people per square kilometre), Waverley (A) (6,900) and North Sydney (A) (5,700) in Sydney, and Port Phillip (C) - St Kilda (5,500) in Melbourne. At the other extreme, there were around 250 Statistical Local Areas (SLAs) in Australia with less than one person per square kilometre.
The main factor changing the distribution of Australia's population has been internal migration. During 2000-01, 380,600 people moved from one state or territory to another, 13,200 more than in the previous year (367,400).

Some areas of Australia have experienced significant population decline in recent years. While some of the population declines have occurred in established suburbs within capital cities and major urban centres, the fastest population decline has occurred in rural areas. Most of this decline has been caused by net migration loss. Such population loss is associated with technological, social and economic changes and industry restructuring in local economies.
