What You'll Learn

Australia is bigger than the continental US
Australia is the world's sixth-largest country, with a land area of approximately 7,688,287 square kilometres. In comparison, the continental US (the lower 48 states) measures around 7,741,220 square kilometres. This makes Australia slightly bigger than the continental US.
To put this into perspective, the distance between the easternmost and westernmost points of Australia is 5030 kilometres, while the distance between the easternmost and westernmost points of the continental US is 4668 kilometres. This means that Australia stretches over a greater distance from east to west than the continental US.
Another interesting comparison between the two countries is their population size. Despite being larger in area, Australia has a significantly smaller population than the US. Australia's population is estimated to be around 27 million people, while the state of Texas in the US alone has a population of about 30 million people. This highlights the vast difference in population density between the two countries.
The sense of space and travel distances within each country also differ greatly. In Australia, travelling to remote areas such as the Outback can take multiple days, whereas in Europe or the US, crossing an entire country or travelling to a remote location can often be accomplished in a couple of hours or days. This underscores the unique geographical characteristics of Australia and the continental US and how they relate to each other in terms of size and scale.
In summary, while both countries are vast and expansive, Australia is indeed bigger than the continental US when considering their total land areas. This size difference has implications for infrastructure and travel planning, as well as the overall sense of space within each country.

North America is 213% larger than Australia
North America is significantly larger than Australia. While Australia spans approximately 7,741,220 square kilometres, North America covers around 24,230,000 square kilometres. This makes North America over twice the size of Australia, or 213% larger to be precise.
To put this into perspective, Australia is the sixth-largest country globally, following Russia, Canada, China, the USA, and Brazil. It accounts for just five percent of the world's land area and is the smallest continental land mass. In contrast, North America is home to two of the six largest countries globally, with Canada ranking second and the United States fifth.
While Australia is larger than the contiguous United States (the lower 48 states), it is worth noting that the US as a country also includes Alaska and Hawaii, bringing its total area to 9,833,517 square kilometres. This makes the US over a million square kilometres larger than Australia.
The difference in size between North America and Australia has implications for travel planning. Australia's smaller size means that it cannot support the same frequency of transport services between destinations. Therefore, careful consideration of travel times and connections is necessary when planning a trip to Australia.
In summary, North America's size advantage over Australia is substantial, with North America being 213% larger than Australia. This size difference has geographical, cultural, and logistical implications for each region.

Australia is the world's largest island
Australia is indeed the world's largest island, and it is also a continent in its own right. With a land area of approximately 7.69 million square kilometers, Australia is not only the sixth-largest country in the world but also the biggest single landmass surrounded by ocean. This distinct geographic position earns it the title of the world's largest island.
In comparison, the continent of North America, which includes both the United States and Canada, is roughly four times the size of Australia. However, if we consider just the United States, which is a country, Australia is significantly larger. The land area of the United States is approximately 3.8 million square miles, while Australia, as mentioned, boasts a size of 7.69 million square kilometers, making it almost twice as large as the US.
The vast size of Australia becomes even more apparent when comparing population sizes. The US population is over 331 million, whereas Australia's population is just under 26 million people. This highlights the significant difference in the population density of the two countries, with the US having a much higher concentration of people per square mile.
Australia's unique geography and natural wonders further emphasize its status as an extraordinary island continent. It is home to the iconic Uluru (Ayers Rock), the Great Barrier Reef, one of the natural wonders of the world, and the vast Outback, a sparsely populated, rugged, and remote region that covers much of the country. These natural landmarks have become synonymous with Australia and contribute to its allure as a diverse and captivating travel destination.
The isolation of the Australian continent has also led to the development of a diverse and unique ecosystem, with many plant and animal species found nowhere else on Earth. This biodiversity is a key feature of the island and contributes to its global significance in terms of conservation and ecological research. Australia's size, natural beauty, and ecological importance firmly establish it as an exceptional and remarkable island on the world stage.

The US has a much larger population than Australia
In terms of land mass, Australia is bigger than the contiguous United States (the lower 48 states). However, the US has a much larger population than Australia. Australia's population is approximately 27 million people, whereas the US population is over 331 million. In fact, the population of the single state of Texas is around 30 million, which is more than the population of the entire country of Australia. This has implications for travel within Australia, with less frequent flights, ferries, trains, and buses compared to the US. This means that careful trip planning is required to ensure that transport connections are not missed.
The vast difference in population between the two countries can be attributed to several factors. One factor is the size of the countries; while Australia is slightly larger in area, the US has a more temperate climate and a greater proportion of arable land, making it more suitable for human habitation. Additionally, the US has a higher population density, with more people living in urban areas. This is due in part to the country's history of industrialization and urbanization, which has led to the development of large cities and metropolitan areas.
Another factor contributing to the population disparity is immigration. The US has a long history of immigration from various parts of the world, while Australia's immigration rates are lower in comparison. The US has also experienced higher birth rates than Australia, which has contributed to its growing population over time. Social and economic factors may also play a role, with the US having a higher standard of living and better access to healthcare and education for much of the 20th century, making it a more attractive destination for immigrants.
The cultural and historical differences between the two countries have also played a role in shaping their populations. The US has a diverse cultural landscape, with a variety of ethnic, religious, and social groups, while Australia has a more homogeneous population. Additionally, the US has a history of colonization and immigration that has shaped its demographic makeup, with various waves of immigration from Europe, Asia, and other parts of the world contributing to its population growth.
Finally, the political and economic policies of the two countries have likely had an impact on their respective populations. The US has a strong economy and a history of political stability, which may have contributed to its population growth. In contrast, Australia has experienced periods of economic fluctuation and political instability, which could have influenced migration patterns and population growth. Nonetheless, Australia has been working to increase its population through immigration and other means, recognizing the potential benefits of a larger population in terms of economic growth and global influence.

Australia is the sixth-largest country in the world
Australia's size is impressive, but it is dwarfed by the largest countries in the world. Russia is the largest country by land mass, and it is so big that even if you take away all of Russia's territory in Siberia, it would still be the largest country in the world. Following Russia in size are Canada, China, the United States, and Brazil. Together, these six countries account for 50% of the world's land area.
While Australia is the sixth-largest country, it is the smallest of the countries that make up a continent of their own. This makes Australia the world's largest island. Its size is comparable to that of Europe, which is considered a continent by many. However, it is worth noting that the Mercator projection, which is commonly used in maps, distorts the size of regions near the poles, making areas like Greenland appear much larger than Australia, when in fact the opposite is true.
Australia's vast size means that travel within the country can be challenging. The country's infrastructure cannot support the same frequency of flights, ferries, trains, and buses as in the United States. As a result, careful trip planning is essential when travelling within Australia, as a simple oversight in booking connections can put your trip in disarray. Despite the challenges, Australia's beauty and unique sense of space make it a rewarding destination for those willing to take the time to explore.
