Australia Population 2020 (Live)

25,500,701

Current projections indicate that Australia’s population will continue to steadily grow for the rest of the century. Australia’s population is about 25.5 million as of 2020 and is projected to grow to 42.68 million people by 2099.

Australia’s population growth rate is 1.18%, adding about 296,000 people to the population over 2019’s population. This is a result of both net migration, which has been about 150,000 per year for the past few years, and natural increase. Australia’s fertility rate of 1.83 births per woman is below the population replacement rate of 2.1 births per woman.

Australia ranks fifth among OECD countries for population growth. As the other OECD countries with high growth rates, Australia has a strong labor demand that cannot be met from domestic sources; therefore, mass migration occurs.

The current population of Australia is 25,500,701, based on projections of the latest United Nations data. The UN estimates the July 1, 2020 population at 25,499,884.

Australia Area and Population Density

Australia is the {rank} largest country in the world in terms of population, between Cameroon and Madagascar. It is also the most populous country in Oceania, three times more populous than its neighbor Papua New Guinea (8.2 million) and 5 times more populous than New Zealand (4.5 million). As the 6th largest nation in the world, Australia has a very low population density of just 3 people per square kilometer, or 7 per square mile. This makes it one of the least densely populated countries in the world. Mongolia, Western Sahara and Suriname have fewer people per square kilometer than Australia. Some parts of Australia are even less densely populated. In the Northern Territory, every square kilometer holds just 0.2 people. Most of Australia's population is concentrated on or around the more hospitable coastal areas, as you can see in the density map further down the page.

The most recent Australian census was held in 2016 and confirmed that the population of Australia was 23,401,892. The Australian Bureau of Statistics also provides the Australian Population Clock, which uses population indicators to estimate the current population count.

Largest Cities in Australia

There are five Australian cities with a population of more than a million people.. Read on for more details on the major metropolitan areas of this country.

Sydney is the home of the Opera House and the Sydney Harbour Bridge, and hosted the 2000 Summer Olympics. Sydney is Australia's largest and most cosmopolitan city.

Melbourne, Australia's second city and a great rival of Sydney, is the capital of Victoria. Situated on the south coast, it was home to 3,999,982 people at the time of the 2011 census. It is growing even more quickly than Sydney and is forecast to become Australia's largest city within 25 years. According to 2016 estimates, the population is 4,529,496, which is 19.05% of Australia's population.

Brisbane, capital of Queensland, had a population of 2,065,996 on the day of the 2011 census. In the five years since the 2006 census, its population grew by an impressive 11.5%. Estimates in 2016 put the population around 2,308,720, or 9.71% of the nation's overall population.

Perth, capital of Western Australia, is the fastest growing state capital in Australia. It's population went up from 1,512,105 in 2006 to 1,728,867 in 2011, a growth rate of 14.3% in just five years. Growth has continued through 2016, with a population estimated to be 2,039,193.

In addition to six states, Australia has ten territories. There are three internal territories: the Australian Capital Territory (ACT), Jervis Bay Territory, and the Northern Territory.

There are seven external territories: Ashmore and Cartier Islands, Australian Antarctic Territory, Christmas Island, Coco (Keeling) Islands, Coral Sea Islands, Heard Island and McDonald Islands, and Norfolk Island. Two of these territories, Ashmore and Cartier Islands and Heard Island and McDonald Islands, are uninhabited. The Australian Antarctic Territory has an approximate population of 60 inhabitants, who are mostly research station staff.

The Australian Capital Territory is an enclave inside of New South Wales. Home to Australia's capital city Canberra, 390,800 people live in the ACT.

The Northern Territory has an estimated 244,600 residents, making it the least densely populated part of Australia and one of the least densely populated areas in the world. Its largest city is Darwin, where more than half of the Territory's residents make their homes.

Australia Population Pyramid

Current projections indicate that Australia’s population will continue to steadily grow for the rest of the century. Australia’s population is about 25.5 million as of 2020 and is projected to grow to 42.68 million people by 2099.

Australia’s population growth rate is 1.18%, adding about 296,000 people to the population over 2019’s population. This is a result of both net migration, which has been about 150,000 per year for the past few years, and natural increase. Australia’s fertility rate of 1.83 births per woman is below the population replacement rate of 2.1 births per woman.

Australia ranks fifth among OECD countries for population growth. As the other OECD countries with high growth rates, Australia has a strong labor demand that cannot be met from domestic sources; therefore, mass migration occurs.
