Australia is the smallest continent and one of the largest countries
Australia is the smallest continent on Earth and one of the largest countries in the world by area. It is located between the Pacific and Indian oceans in the Southern Hemisphere. The Australian mainland extends from west to east for nearly 2,500 miles (4,000 km) and from Cape York Peninsula in the northeast to Wilsons Promontory in the southeast for nearly 2,000 miles (3,200 km). To put this into perspective, travelling from Sydney to Perth (East Coast to West Coast) is roughly equivalent to travelling from New York to Los Angeles.
The country's vast size and global isolation have contributed to the uniqueness of its plant and animal life. Its flora and fauna include hundreds of kinds of eucalyptus trees, acacias, and the only egg-laying mammals on Earth, the platypus and echidna. Other animals commonly associated with Australia include dingoes, kangaroos, koalas, and kookaburras. The Great Barrier Reef, off the east coast of Queensland, is the greatest mass of coral in the world and one of the country's foremost tourist attractions.
The Australian mainland is relatively flat, with an average height of 325 metres (1,066 ft) compared to 870 metres (2,850 ft) for all continents. The Great Dividing Range runs along most of eastern Australia, dividing the central lowlands from the eastern highlands. At 2,228 m (7,310 ft), Mount Kosciuszko is the tallest mountain on the mainland. The Murray-Darling is the major river system, draining most of inland New South Wales and Southern Queensland towards Lake Alexandrina and the sea in South Australia.
With a population of about 27 million people, Australia is the planet's sixth-largest country by land area, covering 7,688,287 square kilometres. This accounts for just 5% of the world's land area. Australia is slightly smaller than the continental United States (without Alaska) and has a comparable size to the continental USA.

The mainland extends 4,000 km from east to west
Australia is the smallest continent and one of the largest countries on Earth, lying between the Pacific and Indian oceans in the Southern Hemisphere. The Australian mainland extends 4,000 kilometres (km) from east to west, and 3,200 km from Cape York Peninsula in the northeast to Wilsons Promontory in the southeast. To put this into perspective, travelling from the east coast of Australia to the west coast is roughly the same distance as travelling from New York to Los Angeles in the United States.
The country is characterised by its global isolation, low relief, and aridity. The Great Dividing Range runs along most of eastern Australia, dividing the central lowlands from the eastern highlands. At 2,228 metres (m), Mount Kosciusko is the tallest mountain on the mainland. The Murray-Darling is the major river system, draining most of inland New South Wales and Southern Queensland towards Lake Alexandrina and the sea in South Australia.
Australia has three distinct physiographic regions from east to west: the East Australian Highlands, the Interior Lowlands (also known as the Central Lowlands), and the Western Plateau. Two-thirds of continental Australia consists of the Western Plateau, which covers 2.7 million km² of arid or semi-arid land in Western Australia, South Australia, and the Northern Territory.
The country's unique flora and fauna include hundreds of kinds of eucalyptus trees, acacias (Acacia pycnantha, or golden wattle, is the national flower), and the only egg-laying mammals on Earth, the platypus and echidna.

Sydney to Perth is like New York to LA
Australia is the smallest continent and one of the largest countries on Earth, lying between the Pacific and Indian Oceans in the Southern Hemisphere. The Australian mainland extends from west to east for nearly 2,500 miles (4,000 km). To put it into perspective, travelling from Sydney to Perth on the west coast is about the same as travelling from New York to Los Angeles.
Sydney is on Australia's east coast and is one of the country's most important economic and cultural centres, along with Melbourne. Meanwhile, Perth is located on the west coast of Australia. The distance between the two cities is about 3,290.59 km (2,044.68 miles) in an east direction. This distance is even longer than the distance between Moscow and Paris.
The distance between Sydney and Perth is a good indicator of Australia's vast size. Australia is known for its global isolation, low relief, and the aridity of its surface. Much of the country is sparsely populated, with the Outback, a symbol of Australia's strength and independence, located beyond the Great Dividing Range of mountains that runs along the Pacific coast.
When comparing the distance between Sydney and Perth to that of New York and Los Angeles, it is important to consider the differences in infrastructure and population between the two countries. Australia's population is significantly lower than that of the United States, which affects the frequency of travel options. Therefore, when planning a trip between Sydney and Perth, it is crucial to be mindful of travel times and connections.
In summary, the distance between Sydney and Perth on Australia's east and west coasts is comparable to the distance between New York and Los Angeles in the United States. This comparison highlights Australia's large size and the potential travel considerations when planning a trip between these distant cities.

Australia is as big as the continental USA
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 mainland extends from west to east for nearly 2,500 miles (4,000 km). The country is known for its global isolation, low relief, and aridity. Its unique flora and fauna include hundreds of kinds of eucalyptus trees, the platypus, and the echidna.
Australia is approximately 7,741,220 sq km, while the United States is approximately 9,833,517 sq km, making the United States 27% larger than Australia. However, when comparing mainland Australia to the continental US (the lower 48 states), Australia is a little bigger. To put it into perspective, travelling from Sydney to Perth (East Coast to West Coast) is about the same as travelling from New York to Los Angeles.
The Australian mainland is relatively flat, with an average height of 325 metres (1,066 ft) compared to 870 metres (2,850 ft) for all continents. The Great Dividing Range runs along most of eastern Australia, dividing the central lowlands from the eastern highlands. At 2,228 m (7,310 ft), Mount Kosciuszko is the highest mountain on the mainland.
Australia has a population of about 27 million people, which is similar to the population of the state of Texas. The country has generally strong protections for civil and political rights and has signed up to a wide range of international rights treaties, including the Constitution, the Racial Discrimination Act 1975, and the Sex Discrimination Act 1984.

Australia is the world's sixth-largest country
The country's capital, Canberra, is located in the southeast, between the cultural and economic centres of Sydney and Melbourne. Australia's unique geography and isolation from other continents have contributed to its distinctive flora and fauna, including iconic species such as eucalyptus trees, platypuses, kangaroos, and koalas. The Great Barrier Reef, off the east coast of Queensland, is another renowned natural wonder, attracting tourists from around the world.
Australia's size is comparable to that of the continental United States, and travelling from its east coast to the west coast is akin to travelling from New York to Los Angeles in the United States. This vast expanse presents challenges in terms of travel planning, as Australia's infrastructure cannot support the same frequency of transportation options as more densely populated countries. Therefore, visitors must carefully consider travel times and connections to avoid hiccups in their vacation plans.
The country's geographical features also include coastal river systems, inland drainage systems like the Lake Eyre system, and salt lake systems in central and western regions. The Australian mainland is relatively flat, with an average height of 325 metres, and its highest mountain, Mount Kosciusko, reaching 2,228 metres (7,310 feet) above sea level. Despite its relatively low elevation, Australia experiences seismic activity due to the movement of the Australian plate, which collides with the Eurasian and Pacific plates.
