Australia is a large country, with a land area of 2.989 million square miles, or 7.69 million square kilometres. As of December 2024, Australia's population was 27,400,013 people, with an annual growth rate of 1.7%. But how many people could the country actually fit? One suggestion is that, with the construction of skyscrapers, the entire world population could fit into Australia. However, this idea presents several issues, including the need for farmland and the potential impact of a terrorist strike on one of these skyscrapers. Another estimate suggests that, based on the population density of Singapore, Australia could be home to 63.7 billion people. However, this figure is over eight times the current world population and does not take into account the ecological footprint of such a large population. A more realistic estimate puts the number at around 40 million people.

What You'll Learn
Current population
Australia's population was 27,400,013 people at the end of 2024, with a quarterly growth of 91,133 people (0.3%) and an annual growth of 445,900 people (1.7%). The population growth is comprised of natural increase (births minus deaths) and net overseas migration (migration arrivals minus migration departures).
The land area of Australia is 2.989 million square miles, or 7.69 million square kilometres. If we use the "human sardine model", we could fit 39 trillion people into Australia if we accept that people can walk on water. However, if we want to remain within legal free-range limits, we could only fit approximately 7.69 trillion humans.
Another estimate suggests that about 40 million people could live in Australia. To put this in perspective, this is the same population density as Singapore, which has a population density of more than 8000 people per square kilometre.
In reality, Australia's population is significantly less than that of the United States, with about 27 million people compared to Texas's 30 million. This has implications for infrastructure and travel planning, as Australia cannot support the same frequency of flights, ferries, trains, and buses between destinations.

Population density
Australia's land area is 7.69 million square kilometres or 2.989 million square miles. As of December 2024, Australia's population was 27.4 million people, with an annual growth rate of 1.7%. This makes Australia a sparsely populated country, with a population density of 3.5 people per square kilometre.
If we compare this to one of the world's most densely populated places, Singapore, with a population density of more than 8,000 people per square kilometre, we can see the vast difference. If Australia had the same population density as Singapore, its population would be 63.7 billion people, which is more than eight times the Earth's current population.
The idea of fitting the world's population into Australia has been a topic of discussion and speculation. Some calculations suggest that if everyone in the world had a classroom-sized area, they could fit into Australia with room for amenities, parks, roads, and factories. Others have suggested that with the use of skyscrapers, the world's population could live in Australia with plenty of room to spare. However, these ideas do not take into account the infrastructure and resources needed to support such a dense population.
Additionally, it is important to consider the ecological impact of a growing population. Even with a much smaller population than the speculative scenarios, Australia's population growth has been linked to an increasing ecological footprint and worsening climate crisis. Therefore, while there may be ways to physically fit more people into Australia, it is crucial to balance this with the need to protect the environment and ensure sustainable practices.

Skyscraper solution
Australia is a large country, with a land area of 2.989 million square miles or 7.69 million square kilometres. As of December 2024, Australia's population was 27.4 million people.
The skyscraper solution is a proposed idea that if skyscrapers were built in Australia, more people could live in the country. The idea is based on the assumption that if each person had their own house with a garden, there would not be enough space for everyone. However, if people lived in skyscrapers, there would be more room for amenities, parks, roads, factories, and recycling plants.
To accommodate the world's population in Australia, the skyscrapers would need to be enormous. One calculation suggests that a building with 137 stories and 48,956,154 flats per story could accommodate the entire world's population. However, this idea presents several challenges and risks. Firstly, not everyone may want to live in a skyscraper, and the densely packed buildings would leave little to no room for farmland, raising concerns about food supply. Secondly, the potential impact of a terrorist strike or similar disaster on a single skyscraper could result in a significant loss of life.
To address these concerns, an alternative suggestion is to build a single giant skyscraper that takes up the entire country. While this idea may seem outlandish, it could potentially provide enough space for the world's population while also allowing for the necessary infrastructure and amenities.
In conclusion, the skyscraper solution proposes that building upwards with skyscrapers could enable a larger population to live in Australia. However, this idea presents several logistical and safety challenges, and it may not be a desirable living situation for everyone. As such, it is important for Australians to strive to reduce their ecological footprint, particularly in light of the worsening climate crisis.

Ecological footprint
Australia has long been considered a biocapacity giant due to its enormous landmass and relatively small population. The country's biocapacity, or the amount of living matter its ecosystems can regenerate, has consistently been estimated to be two to three times the size of its ecological footprint.
However, the ecological footprint of the average Australian is approximately 6 hectares per capita, which is more than four times the globally available 'fair share'. This places Australia among the top consuming nations in the world. Australians require a huge ecological footprint to sustain their lifestyles, with just 12 nations in the world using up more arable land and carbon-burning generation. This large ecological footprint is due to the country's high consumption of energy and animal products, contributing to deforestation, overfishing, and the release of more carbon into the atmosphere than forests and oceans can absorb.
The devastating fires of the Black Summer of 2019-2020 turned Australia's biocapacity reserve into a deficit for the first time in its history. The loss of living matter and biodiversity due to the destruction of mature ecosystems was catastrophic. This abrupt change highlighted the unsustainable nature of the Australian lifestyle and the need to reduce their ecological footprint in light of the worsening climate crisis.
While some have suggested that Australia's population density could be increased to accommodate more people, this would likely result in an even larger ecological footprint for the country. It is important to consider not only the physical space available but also the impact on the environment and the resources needed to sustain a larger population. Therefore, instead of focusing on fitting more people into Australia, the priority should be on reducing the ecological footprint of the existing population to ensure long-term sustainability and protect the country's unique ecosystems.

Infrastructure
Australia's infrastructure is facing a number of challenges due to the country's rapid population growth. The current growth rate is 2.1%, which is significantly higher than the average of major Western countries, which is 0.25% per year. This growth is expected to lead to a population of 45 million by 2050, and over 100 million by 2100.
This rapid growth is already causing issues, such as water shortages, increasing pollution, traffic congestion, and the loss of arable land to housing. To accommodate this growing population, Australia will need to focus on developing infrastructure in a sustainable way, ensuring that it can serve the public interest and meet the country's future needs.
One way to do this is through integrated land use and transport planning, creating better urban environments for people. This could include improving regional rail signalling, level crossing removals, and active transport options. However, there are barriers to implementing these changes, including coordination issues across the government and access to finance for sustainable infrastructure projects.
Another challenge is the skills shortage across the infrastructure sector. The demand for civil engineers, project managers, and infrastructure professionals is outstripping supply, and addressing this will be key to ensuring that infrastructure projects can be completed on time and within budget.
Additionally, Australia needs to address issues with its supply chain. Almost half of the money spent by construction companies goes to outsourcing services, and there are concerns about the resilience of the supply chain. Strengthening sovereign capability and identifying opportunities to grow domestic production, such as through the analysis of domestic steel production capacity, could help to address these issues.

Frequently asked questions
Australia's land area is 2.989 million square miles, or 7.69 million square kilometres. If we use the human sardine model, we could fit 39 trillion people into Australia. However, this doesn't take into account the need for infrastructure and amenities. A more realistic estimate is around 40 million people, based on the population density of Singapore.
If we built skyscrapers instead of traditional houses, we could fit even more people into Australia. However, this would require a significant amount of resources and could be a potential safety hazard.
The world's population is estimated to be around 6.8 billion people. Australia's land area is only about a third of the land area of the entire world, so it is unlikely that Australia could fit the entire world's population, even with high-rise buildings.
As of December 2024, Australia's population was approximately 27 million people. This is significantly less than the population of the United States, which is estimated to be around 330 million people.
