Australia is the sixth-largest country in the world, with a land area of approximately 2,969,907 square miles. Despite its massive size, it has a sparse population. Australia has one of the lowest population densities in the world, with only nine people per square mile or 3.3 people per square kilometre as of June 2020. This is due to the arid and desert geography of much of the interior of the country, with around 70% of Australia considered arid or semi-arid. The availability of water is a significant challenge in the country's vast deserts, making human settlements in these areas difficult.

What You'll Learn
The majority of the country's population lives along the coast
Australia is the sixth-largest country in the world, with a land area of approximately 2,969,907 square miles. Despite its size, Australia is sparsely populated, with one of the lowest population densities globally, at about nine people per square mile or 3.3 people per square kilometre as of June 2020. This is in stark contrast to countries like Monaco, Singapore, and Malta, which have much higher inhabitants per square mile.
The majority of Australia's population is concentrated along its expansive coastline. In 2019, 87% of Australians, or over 22 million people, lived within 50 kilometres of the coast. This trend of coastal living has been steadily increasing, up from 85% in 2001. The coastal population is spread across major cities like Sydney and Melbourne and smaller coastal townships and villages.
There are several reasons why most Australians choose to live near the coast. Firstly, the interior of Australia is largely desert, also known as the Outback, covering around 70% of the country. These arid and semi-arid regions present extremely challenging living conditions due to their harsh, dry climate and limited access to water. The availability of water is a significant challenge in the vast deserts of Great Sandy, Victoria, Gibson, Tanami, and Simpson.
Additionally, the coastal cities offer more job opportunities and convenient access to amenities and services. The higher population density in these areas can also provide benefits such as increased eco-friendly regulations and sustainable urban development. However, the concentration of people in these regions has led to various environmental concerns, including coastal pollution, solid waste management, and the impact of human activities on fragile coastal ecosystems.
The Australian government has recognised the need to address the sparse population in certain regions. They have allocated resources to programs aimed at increasing the overall population, with a focus on attracting migrants to maintain a robust economically active demographic. These initiatives seek to improve trade conditions, boost tourism, and increase tax revenues.

The outback is sparsely populated
Australia is the sixth-largest country in the world by area, but it has one of the lowest population densities, with only about three to nine people per square mile. The country's population is heavily concentrated along the coastlines, with 89% of Australians living in urban areas. The outback, which refers to the remote arid lands that make up the Northern Territory, Western Australia, South Australia, New South Wales, and Queensland, is sparsely populated.
The interior of Australia is largely desert, making human settlements challenging due to extreme conditions. About 70% of the country is considered arid or semi-arid, making it the driest continent. The limited access to water in these regions, covering over 386,000 square miles, contributes to the sparse population. The outback is characterised by vast wilderness areas with red sand dunes and rocky formations, such as the Simpson Desert.
Depopulation of large Australian regions has led to a reliance on activities like mining and livestock grazing. Mining often occurs in remote locations, while beef production happens on large tracts of land with little rainfall. The low population density in the outback also impacts birth rates, and the Australian government has allocated resources to increase the population for improved trade, tourism, and tax revenues.
The outback's sparse population is evident in its small towns like Alice Springs, the third-largest city in the Northern Territory, covering 10% of the region. Alice Springs relies heavily on tourism, with nearby Uluru Mountain being a popular destination. The town's economy has diversified since its early days as a service hub for the pastoral industry, benefiting from the introduction of a railway line.
In summary, the outback regions of Australia are sparsely populated due to their arid and desert geography, challenging living conditions, and historical factors like depopulation and nomadic lifestyles. These areas contribute significantly to Australia's overall low population density, which stands in contrast to the higher densities found in its major cities.

Australia is the sixth-largest country in the world
Despite its massive size, Australia is sparsely populated, with one of the lowest population densities in the world. As of June 2020, Australia's population density was 3.3 people per square kilometre, compared to 464 people per square kilometre in India and 36 people per square kilometre in the United States. To put this into perspective, countries like Monaco, Singapore, and Malta have much higher population densities, with over 47,000, 20,000, and 4,000 inhabitants per square mile, respectively.
The low population density in Australia is due to several factors. Firstly, the interior of the country is mostly desert, with extreme living conditions. Around 70% of Australia is considered arid or semi-arid, making it the driest continent on the planet. Limited access to water in these regions contributes to the sparse population. Secondly, most of Australia's population is concentrated along the coast in the biggest cities, such as Sydney, Melbourne, and Brisbane. This urbanisation leads to higher population densities in these cities, while leaving vast rural areas sparsely populated.
The Australian government has recognised the benefits of a larger population and has allocated resources to programs aimed at increasing the population. A larger population would lead to improved trade conditions, increased tourism, and higher tax revenues. Additionally, a higher population density can offer more job opportunities and improve urban sustainability by creating more sustainable cities. However, living in densely populated areas comes with challenges such as high costs of living, reduced green spaces, and overcrowding.
In conclusion, Australia, the sixth-largest country in the world, presents a unique scenario of vast landscapes and a sparse population. This combination has shaped the country's demographics, economy, and sustainability efforts, leading to a diverse and dynamic nation with a distinct character.

The interior of Australia is arid and semi-arid
Australia is the sixth-largest country in the world, with a land area of approximately 2,969,907 square miles. Despite its size, Australia is sparsely populated, with one of the lowest population densities globally, at about nine people per square mile or 3.3 people per square kilometre. The interior and west of the country are largely arid or semi-arid desert regions, making human settlement challenging due to harsh conditions.
Around 70% of Australia is considered arid or semi-arid, making it the driest continent. The availability of water is a significant issue in the Great Sandy, Victoria, Gibson, Tanami, and Simpson deserts. These arid conditions cover over 386,000 square miles, contributing to the sparse population. The desert area in which the city of Alice Springs is located is known as the Red Centre, and the nearby Simpson Desert is a vast wilderness of red sand dunes and rocky formations.
The Outback refers to the remote arid lands with sparse populations in the Northern Territory, Western Australia, South Australia, New South Wales, and Queensland. The Outback's harsh conditions make it difficult to sustain large populations, and the limited access to water further challenges human settlement. The arid regions of Australia rely on activities like mining and livestock grazing, particularly cattle and sheep grazing, for economic support.
While Australia's major cities have population densities comparable to other Western countries, the vast empty spaces in the interior contribute to a low overall population density. This disparity between densely populated cities and the sparsely populated interior is a unique characteristic of Australia's demographics.

The population density of Australia's major cities
Australia is the sixth-largest country in the world by land area, with approximately 2,969,907 square miles. Despite its massive size, Australia is sparsely populated, with one of the lowest population densities globally, at 3.5 people per square kilometre as of June 2024. This figure represents a slight increase from the 3.3 people per square kilometre recorded in June 2020. To put this into perspective, countries like Monaco, Singapore, and Malta have significantly higher population densities, with 47,000, 20,000, and 4,000 inhabitants per square mile, respectively.
The low population density in Australia is largely due to the challenging living conditions in its interior regions, which are predominantly desert or semi-arid areas, often referred to as the Outback. About 70% of Australia falls into this category, making it the driest continent on Earth. The limited access to water in these regions, covering over 386,000 square miles, contributes significantly to the sparse population outside of major cities.
Despite the overall low population density, Australia's major cities exhibit varying levels of population density. Sydney, Melbourne, and Brisbane are among the most densely populated urban areas in the country. Sydney stands out with the largest combined area in the high and very high-density classes (194 km²), followed by Melbourne (69 km²) and Brisbane (24 km²). These cities have witnessed strong population growth, leading to the expansion of suburban areas and the conversion of natural landscapes into apartment buildings and houses.
Other capital cities, such as Perth, Canberra, and Adelaide, also have areas classified as high or very high density, although on a smaller scale compared to the previous three cities. Adelaide, for instance, experienced a population increase due to net overseas migration, particularly in the central business district and surrounding areas. Perth, with over 2 million people, is considered the fourth most populated city in Australia and the most isolated city globally.
The high population density in these major cities brings certain drawbacks, including the high cost of living. Apartments in these cities can be incredibly expensive, often costing millions. Additionally, high population density can lead to overcrowding, impacting urban sustainability and the availability of green spaces. However, living in densely populated areas offers advantages such as increased job opportunities and improved access to amenities and services.
