Population density of Australian states
Australia is one of the least densely populated places in the world, with an average population density of fewer than seven people per square mile or 3.3 people per square kilometre. This is due to the fact that most of the country's interior is desert, making living conditions extremely difficult. However, the population is mainly concentrated in urban areas, with 89% of Australians living in urban areas, and 79% in the eastern coastal mainland states of New South Wales, Queensland, Victoria, and the Australian Capital Territory.
The Australian Capital Territory (ACT) has the highest population density in the country, with 445.89 persons per square mile or 171.40 persons per square km. The territory is home to Canberra, the nation's capital city, and houses significant buildings such as Parliament and the National Gallery of Australia.
The state of Victoria has a population density of 69.92 people per square mile, with Melbourne, the country's second most populous city, located within its borders. Other large cities in Victoria include Geelong, Barrat, and Bendigo. The state is recognised as Australia's cultural centre, known for its boutiques, graffiti laneways, and thriving café scene.
Tasmania, Australia's smallest territory, has a population density of 19.6 people per square mile. The territory has a population of 516,600 people and its capital city is Hobart, the second oldest city in Australia. Tasmania's landscape is mostly mountainous, with about one-fifth of its area covered by national parks and wilderness.
While Australia's overall population density is low, its major cities, such as Sydney and Melbourne, have higher population densities comparable to other Western countries. These densely populated regions attract large populations due to economic factors, favourable climate, steady housing, and bustling cities.

Population growth in Melbourne
Australia is one of the least densely populated countries in the world, with fewer than seven people per square mile on average. However, Melbourne, the country's second most populous city, has experienced significant population growth in recent years. Between 2023 and 2024, Melbourne's population grew by 142,600 people, a 2.7% increase that marked the largest jump in population growth in the country. Melbourne's population currently stands at 5,350,705, while Sydney, Australia's largest city, has a population of 5,557,233.
Melbourne's population growth has been driven by several factors, including natural increase, internal migration, and overseas migration. Overseas migration accounts for almost 90% of the population increase in the capital cities, with students contributing significantly to the growing populations in suburbs close to universities. Melbourne has experienced a slightly higher net migration rate than Sydney, driven by its expanding economy and dynamic job market in sectors like technology, education, and healthcare. The city's relatively more affordable housing compared to Sydney has also made it a more attractive destination for migrants and residents.
Melbourne's focus on expanding its transportation network, including new train lines and road expansions, has facilitated suburban growth in areas like Rockbank-Mount Cottrell, which offer more affordable housing and spacious living environments. The city's cultural offerings, famous boutiques, graffiti laneways, and thriving café scene also contribute to its increasing attractiveness as a destination for migrants.
Melbourne's population growth has significant implications for urban planning, infrastructure development, and economic growth. The city's broader approach to urban planning, including initiatives to expand its transportation network, has been effective in sustaining higher growth rates compared to Sydney. Understanding the annual population growth trends in Melbourne provides valuable insights into its future trajectory and the challenges it may face, particularly regarding housing affordability and congestion.

In 2022, the estimated population of Greater Sydney was 5,302,736, with a population density of 429 people per square kilometre, including surrounding national parks. This figure represents a significant increase from the post-war years, when immigrants and their children accounted for over three-quarters of Sydney's population growth between 1947 and 1971.
Sydney's urban development has been largely shaped by the widespread use of motor vehicles, with the growth of low-density housing in the outer suburbs leading to high levels of car ownership and significant traffic congestion. However, the city has the highest usage of public transport in Australia, at 27%strategies are being implemented to encourage a shift towards public transport and reduce private vehicle pollution.
The population density of Sydney has resulted in both benefits and drawbacks for its residents.

However, it has also resulted in increased pollution and reduced autonomy for residents.

Tasmania's population
Australia is a country with a vast land area but a relatively small population, and this is reflected in its population density, which is low compared to many other countries. Within Australia, the island state of Tasmania has the distinction of being the most densely populated state. With a total land area of over 68,000 square kilometers, Tasmania is home to a population of around 540,000 people as of 2023, resulting in a population density of approximately 7.9 people per square kilometer. While this makes Tasmania the most densely populated Australian state, it is still relatively sparsely populated compared to many other places in the world.
Outside of Hobart, other significant population centers in Tasmania include the cities of Launceston, Devonport, and Burnie. Launceston, the state's second-largest city, has a population of over 110,000 people and is known for its picturesque setting along the Tamar River. Devonport, on the northern coast, is a major transport hub and a gateway to the state, with a population of around 30,000. Burnie, another coastal city, has a strong focus on industry and agriculture and is home to over 19,000 people. These regional centers offer a different pace of life to Hobart, with a strong sense of community and a more relaxed lifestyle.
While Tasmania's population is relatively small compared to other Australian states, it has been steadily growing. The state has seen positive net migration in recent years, with people moving to Tasmania for its lifestyle, natural environment, and increasingly, remote work opportunities. The COVID-19 pandemic may have also played a role in this shift, with some people seeking less densely populated areas. Additionally, Tasmania has a relatively high life expectancy, contributing to a growing aging population. This trend is expected to continue, with the Tasmanian Government predicting the state's population to reach 625,000 by 2050.
The demographics of Tasmania's population also present some unique characteristics. The state has an aging population, with a higher median age (42 years) than the national average (37 years). This is partly due to the attraction of Tasmania as a retirement destination, offering a relaxed lifestyle and natural environment. Additionally, Tasmania has a significant gap in its gender balance, with around 51% of the population being female. This imbalance is most pronounced in the older age groups, which may be a result of historical migration patterns and life expectancy differences between genders.
In summary, Tasmania, the island state of Australia, is the country's most densely populated state. With a population of around 540,000 people, it offers a mix of urban and rural lifestyles. The capital city, Hobart, is the main population center, attracting residents and visitors alike with its unique blend of heritage and natural beauty. While Tasmania's population is small compared to other global cities, it is growing, and the state is expected to continue to attract new residents with its unique charm and lifestyle offerings.
