What You'll Learn
Australia is the sixth-largest country in the world
The country is highly urbanised, with a population of almost 28 million. The majority of the population is concentrated along the eastern seaboard, with the most populous cities being Sydney and Melbourne, each with over five million people. Canberra, the nation's capital, is located between these two cities. Australia has one of the world's highest foreign-born populations, contributing to its diverse culture. The country also has a highly developed economy and one of the highest per capita incomes globally, with abundant natural resources and well-developed international trade relations.
The Aboriginal Australians, the indigenous people of the Australian mainland and its islands, have one of the oldest living cultures in the world. They began arriving from Southeast Asia between 50,000 and 65,000 years ago and spoke 250 distinct languages before British settlement. The Madjedbebe rock shelter in Arnhem Land is the oldest site showing human presence in Australia. The written history of Australia began with Dutch exploration of its coastline in the 17th century, and the country was officially federated in 1901.
Australia is a member of various international groups, including the United Nations, the G20, the OECD, and the World Trade Organization. It is a federal parliamentary democracy and constitutional monarchy, with six states and ten territories. The country has a diverse geography, economy, and culture, making it a significant player on the world stage.

It's the smallest continent
Australia is the smallest continent, encompassing a land area of approximately 7.69 million square kilometers. In comparison to other continents, Australia's size can be put into perspective. For example, Russia, the largest country in the world, has a land area of over 17 million square kilometers, almost twice the size of Australia. Even continents such as Asia and Africa far surpass Australia in terms of size, with Asia being more than ten times larger and Africa nearly triple the size.
Despite its small size relative to other continents, Australia is often considered deceptively large when compared to countries. In fact, Australia is the sixth-largest country in the world, bigger than Brazil and India. This is due to the vast expanse of land that makes up the Australian continent, including its remote and sparsely populated interior. The continent stretches approximately 4,000 kilometers from east to west and 3,200 kilometers from north to south, giving it a similar land area to that of the United States of America, although the US has an additional state in Alaska.
The vast majority of Australia is comprised of arid and semi-arid land, with desert or semi-arid conditions covering around 40% of the continent. This has contributed to the relatively low population density, with the majority of Australians living along the coastal regions, particularly in the southeast corner. The largest cities, Sydney, Melbourne, and Brisbane, are all located in this region, which benefits from a more temperate climate.
The unique geography and isolation of the Australian continent have also contributed to its diverse and distinct flora and fauna. The continent is renowned for its endemic species, including iconic animals such as the kangaroo, koala, and wombat, as well as the famous eucalyptus trees. The Great Barrier Reef, located off the northeast coast, is another natural wonder unique to Australia and is the world's largest coral reef system.
In conclusion, while Australia is the smallest continent, it offers a diverse and expansive landscape. Its size compared to other continents highlights its relatively compact nature, yet within its borders lie a variety of environments and ecosystems. From the tropical rainforests of the north to the snowy mountains of the southeast, and from the vast outback in the interior to the vibrant coral reefs along the coast, Australia's small continent packs in a wealth of natural wonders and unique attractions.

The mainland extends 4,000 km east to west
Australia is the planet's sixth-largest country by area, at 7,688,287 square kilometres (2,968,464 square miles). It is the smallest continental land mass, but the largest island. The mainland extends 4,000 kilometres (2,500 miles) from east to west.
The northernmost points of the continental mainland are the Cape York Peninsula of Queensland and the Top End of the Northern Territory. The mainland extends south to Wilsons Promontory in the southeast. Off the north-eastern coast of Australia is the world's largest coral reef complex, the Great Barrier Reef.
The geography of Australia encompasses a wide variety of biogeographic regions. The Western Plateau region is generally flat, although it is broken up by mountain ranges such as the Hamersley Range, the MacDonnell Ranges, and the Musgrave Range. The Eastern Highlands, or Great Dividing Range, lie near the eastern coast of Australia, separating the relatively narrow eastern coastal plain from the rest of the continent.
Australia is the flattest, driest, and oldest inhabited continental landmass on Earth. It has a relatively stable geological history, with minor earthquakes occurring frequently and major earthquakes measuring greater than magnitude 6 occurring on average every five years.

Australia has no land borders
Australia is a large country with a total land area of about 7.7 million square kilometres. To put that into perspective, it's comparable in size to the continent of Europe. Now, one of the defining geographical features of Australia is that it's an island continent, surrounded entirely by oceans. This means that Australia has no land borders with any other country. The continent of Australia is unique in this regard, as it is the only continent that is also a single country, and its isolation has had a significant impact on the country's history, environment, and culture.
Being an island, Australia's borders are defined by its coastline, which stretches over 35,876 kilometres. That's a lot of beachfront! The country is surrounded by the Indian Ocean to the west and south, the Southern Ocean to the south, and the Pacific Ocean to the east. These oceans provide a natural and formidable border, influencing everything from the country's defence strategies to its marine life and surfing culture.
The absence of land borders has had a profound impact on Australia's history and development. It has meant that, unlike many other countries, Australia has not had to contend with land-based invasions or disputes over territorial borders with neighbouring land-based countries. This has contributed to a sense of isolation and insularity, with the country often referred to as 'the lucky country', due to its natural defences and relative geographic isolation.
This isolation has also influenced the country's unique flora and fauna. Being separated from other land masses has allowed Australia to develop its own distinct ecosystems, with many species found nowhere else on Earth. The famous (or infamous) examples include kangaroos, koalas, and the deadly box jellyfish. This biodiversity is a source of pride for Australians and a drawcard for tourists, but it has also led to challenges in conservation and managing invasive species.
The lack of land borders has also had an impact on Australia's culture and national identity. With no immediate land-based neighbours, Australians have often looked inward, fostering a strong sense of national pride and a unique identity. This has manifested in a range of ways, from the iconic 'Aussie' slang and laid-back attitude to the country's strong sporting culture, with a fierce rivalry between its states and a passion for outdoor pursuits.
In conclusion, Australia's vast size and unique position as an island continent have had a profound impact on its history, environment, and culture. The absence of land borders has shaped the country in numerous ways, from its defence strategies and sense of isolation to its biodiversity and national identity. This distinct geography continues to play a role in shaping Australia's future, influencing everything from its tourism campaigns to its international relations and environmental policies.

It's the world's driest and flattest inhabited continent
Australia is not only an extensive landmass but also distinctive in its physical attributes. It stands out as the world's driest and flattest inhabited continent, a characteristic that shapes both its natural landscapes and human habitation. With a median elevation of approximately 330 metres, it is undeniably flat when compared to other continents. This flatness is accentuated by the vast interior lowland region, the Australian Shield, which covers a significant portion of the country.
The shield is an ancient landscape, geologically stable, and marked by low relief. It encompasses vast expanses of arid and semi-arid terrain, with sparse vegetation cover, and is characterized by a hot, dry climate. This central region, often referred to as the Outback, embodies the quintessential image of Australia's rugged and remote interior. The shield is also home to some of the world's most remarkable natural wonders, including the iconic Uluru (Ayers Rock), a testament to the continent's geological antiquity.
Australia's aridity is another defining feature. The continent experiences low rainfall and has a generally hot, dry climate, making it the driest of all inhabited continents. This is due in part to its position within the horse latitudes, which are known for their high-pressure systems that inhibit rainfall. The aridity is most pronounced in the interior regions, with areas like the Simpson Desert and the Great Victoria Desert receiving minimal rainfall annually.
The combination of flat terrain and aridity has had a profound impact on Australia's ecology and human settlement patterns. The continent is known for its unique flora and fauna, which have adapted to these challenging environmental conditions. Australia boasts an incredible diversity of endemic species, including iconic marsupials like the kangaroo and koala, as well as a myriad of unique bird and reptile species. The human population, on the other hand, is predominantly concentrated along the coastal fringes, where the climate is more temperate and the land more conducive to agriculture and urban development.
Despite the challenges posed by its arid and flat landscape, Australia has a rich Indigenous heritage, with Aboriginal Australians having inhabited the continent for tens of thousands of years. These first Australians adapted to the harsh interior regions, developing a deep understanding of the land and a strong cultural connection to it. Today, Australia's interior continues to hold cultural and spiritual significance for Indigenous Australians, even as the majority of the population resides in coastal urban centres.
In summary, Australia's distinct geography sets it apart from other continents. Its flat, arid landscape is both a physical challenge and a source of natural wonder, shaping the country's ecology, human settlement patterns, and cultural heritage. This unique environment has fostered a diverse and resilient natural world, as well as a distinct human culture that continues to evolve and thrive in the face of these geographic characteristics.
