Australia’s population

Australia’s population story

Australia has a history of strong population growth. It has defined the Australia we know today — our world-class cities, our strong economy, our diverse communities, and our way of life.

For much of Australia’s history, population growth has been urban population growth. This trend is not unique to Australia but Australia is more urbanised than many countries. The proportion of people concentrated in cities, and particularly capital cities, is larger now than at any time in our history.

Two in every three Australians live in a Capital City

Sydney, Melbourne, and South East Queensland together accounted for around 75 per cent of population growth over the last three years. Strong population growth in Australia’s three largest cities is spilling over into surrounding areas and this is creating vibrant cities which are becoming strong population centres in their own right.

At the same time, some of Australia’s smaller cities and regional or remote areas are experiencing low growth or declining populations.

But Australia’s population story is not just one of growth or decline. It is the story of a diverse group of people. Australians come from every corner of the globe. We speak over 300 languages (including 150 indigenous languages) and practice over 100 religions.

How does the population grow?

Population growth (or decline) occurs when people are born or die, arrive or depart…

There are two ways Australia’s population can grow

Natural increase

Internal changes in the population called natural increase is births minus deaths.

Net overseas migration

People entering and departing Australia is called net overseas migration (NOM). NOM is arrivals to Australia minus departures.

Below the national level, there is a third way that population can grow (or shrink)

Net internal migration

Movements within Australia are called net internal migration (NIM). NIM is arrivals from other areas of Australia minus departures.
