Australia is the smallest continent and one of the largest countries on Earth, with a relatively small population. There are two main reasons for this: water and soil. Australia is the driest permanently inhabited continent, and there is a lack of arable soil due to its geography and climate. Additionally, the vast country is quite isolated, with a low relief, and much of its surface is arid. The population growth in Australia has been reasonably fast by developed country standards, with a 3.5 times increase since 1945, and the country has the highest rate of immigration of any developed country. However, the lack of infrastructure outside of major cities and the cost of living in more remote areas also contribute to the smaller population in these regions.

What You'll Learn
Australia is the driest permanently inhabited continent
Australia is the smallest continent and one of the largest countries on Earth, lying between the Pacific and Indian oceans in the Southern Hemisphere. Its geographical location makes it one of the two dry bands on the globe due to global air circulation above and below the equator. This aridity, along with the lack of arable soil, makes it relatively uninhabitable. Australia is the driest permanently inhabited continent.
The Outback, or the sparsely populated Inland, is a symbol of Australia's strength and independence. It is familiar to Australians and evokes nostalgia. However, visitors from the Northern Hemisphere may be overwhelmed by the "vast, uninhabited land and the grey charred bush". The Outback retains some of the mystical qualities it had for the first explorers, who searched for inland seas and great rivers.
The lack of water and soil are two simple reasons that limit human habitation and activities in Australia. The country has experienced no glacial activity for around 300,000 years, resulting in a relatively flat landscape with old and thin soils due to natural erosion. This, combined with Australia's geographic location, contributes to the aridity of the land.
While Australia's population growth rate has been fast by developed country standards since 1945, the country faces challenges in building major cities due to the lack of infrastructure. Australia's unique characteristics, including its global isolation, low relief, and aridity, also contribute to the small population density. Climate change is expected to exacerbate these issues, making some inland areas less habitable in the future.

Geographic location results in a lack of arable soil
Australia is the smallest continent and one of the largest countries on Earth. Its geographic location results in a lack of arable soil, which, along with water scarcity, limits human habitation and activities. Australia is situated between the Pacific and Indian Oceans in the Southern Hemisphere, within a dry band on the globe due to global air circulation below the equator. This position results in the country's aridity and the lack of fertile soil necessary for agriculture and supporting a large population.
The absence of glacial activity on the continent for approximately 300,000 years has further contributed to the country's flat topography and the erosion of its soil. The natural erosion processes have resulted in old and thin soil layers that are not conducive to extensive agriculture. This is in contrast to regions that have experienced more recent glacial activity, where glaciers deposit fertile soil as they recede, creating new land for farming and settlement.
The geographic location of Australia, with its unique climate and soil characteristics, has influenced the country's population distribution and density. The Great Dividing Range, a mountain range running along the Pacific coast, separates the sparsely populated Inland or Outback from the cities in the east. The range also influences rainfall patterns, with the east coast receiving more rainfall and, consequently, having a higher population concentration.
The lack of arable soil in Australia has implications for the country's agriculture and food production capabilities. While Australia currently exports enough food to feed 70 million people, the impact of climate change could exacerbate the challenges associated with arable soil scarcity. Some inland farming communities may become untenable in the future, reducing the country's capacity to produce food and support a larger population.
To address the limitations posed by the lack of arable soil, Australia has had to rely on other resources and industries to sustain its economy and population. The country has experienced rapid population growth in the 20th century, with a 3.5 times increase in population since 1945, outpacing Western European countries. However, the lack of arable soil remains a factor influencing the country's population dynamics and the distribution of human settlements.

The Outback is sparsely populated
Australia is the smallest continent and one of the largest countries in the world. It is known for its low population, which is partly due to the fact that 70% of the country is classified as Outback, and only 5% of the population lives in this region. The Outback is a vast, remote, sparsely populated area that covers approximately 5.6 million square kilometers. It is primarily made up of central and northern regions characterized by arid and desert-like conditions, with red rock deserts, grassland plains, and woodlands. The Outback is home to a unique array of plants and animals, and it is of significant cultural importance, particularly to Aboriginal Australians, who have lived in the area for tens of thousands of years.
The low population density in the Outback has led to unique social and economic dynamics. For example, the Royal Flying Doctor Service provides essential medical and ambulance services to remote communities. Additionally, the School of the Air educates children in the Outback through satellite telecommunication, as the number of children in many communities is too small for conventional schools to operate.
The Outback's sparse population also contributes to its economic activities, which primarily include agriculture, tourism, and mining. The vast and remote nature of the Outback makes it ideal for these industries, with grazing and mining being particularly valuable due to the large areas of land available. The Outback's rugged beauty and natural attractions, such as Devils Marbles, Kakadu National Park, and Uluru (Ayers Rock), draw tourists from all over the world, contributing significantly to the region's economy.
While the Outback is sparsely populated, it holds a special place in Australian heritage, history, and folklore. It is deeply ingrained in the country's culture and has been a popular subject in art and literature, especially in the 1940s. The Outback's vast and untouched landscapes evoke a sense of mysticism and nostalgia for Australians, symbolizing the country's strength and independence.

Australia's infrastructure cannot support a larger population
The issue is further exacerbated by the fact that Australia's major cities are already planned and built up, leaving no room to retrofit new infrastructure without expensive additions like land buy-backs and tunnelling. The ongoing failure to deliver infrastructure leads to congestion and lower productivity. Furthermore, Australia's geographic location and climate make it the driest permanently inhabited continent, with a lack of arable soil. Many regional towns do not have enough reliable water sources to support a larger population.
Additionally, Australia's vast country with its global isolation, low relief, and aridity means that building new major cities would require a significant amount of infrastructure to be put in place before the city itself could be established. The cost of construction is very emissions-intensive, and with a fertility rate of 1.7 children per woman, it would take decades for deaths to overtake births. Thus, it is clear that Australia's infrastructure cannot support a larger population, and attempts to increase the population further will only result in reduced infrastructure services for its citizens.

The cost of living is high
Australia is one of the largest countries on Earth, yet it has a relatively small population size. One of the reasons for this is the high cost of living in the country.
Firstly, Australia's geographic location contributes to its high cost of living. The country lies in the Southern Hemisphere between the Pacific and Indian Oceans, placing it in one of the two dry bands on the globe due to global air circulation. As a result, Australia is the driest permanently inhabited continent, with low rainfall and a lack of arable soil. This has made it challenging to establish and sustain large populations, particularly in remote and rural areas.
Secondly, the vast distances within Australia impact the cost of living. The country is known for its long driving distances, with vast stretches of uninhabited land separating major cities. For example, driving from Esperance to Kunanurra within the same state involves a 35-hour drive covering 3,227 kilometers. This distance is comparable to driving from Paris to Istanbul, but with a significantly smaller population along the route. The sparse population distribution increases the cost of infrastructure development and maintenance, such as roads, transportation networks, and utilities.
Thirdly, the unique challenges of Australia's climate and environment contribute to the high cost of living. The country experiences extreme weather events, including stinger seasons, cyclone seasons, and the presence of dangerous wildlife such as crocodiles. These factors can increase the cost of living, as communities need to invest in protective measures, emergency response systems, and specialized infrastructure to mitigate these natural hazards.
Additionally, Australia's geographic isolation plays a role in the high cost of living. The country is located far from other highly populated regions, which can lead to higher costs for transportation, trade, and access to international markets. This isolation also impacts the availability and cost of resources, goods, and services, as they need to be sourced and transported over long distances.
Lastly, the historical nomadic lifestyles of some Aboriginal communities in Australia have influenced the population distribution and cost of living. These communities, which have traditionally inhabited sparsely populated areas, may have different sociopolitical environments that do not support or encourage high population densities.
In summary, Australia's high cost of living is influenced by its geographic location, vast distances, unique climate, isolation, and the sociopolitical environment of its Aboriginal communities. These factors collectively contribute to the small population size relative to the country's large land area.
