Australia is a country and a continent
The country of Australia, officially the Commonwealth of Australia, is a federal parliamentary democracy and constitutional monarchy comprising six states and ten territories. Its population of almost 28 million is highly urbanised and heavily concentrated on the eastern seaboard. Canberra is the nation's capital, while its most populous cities are Sydney and Melbourne, both with a population of more than five million.
Australia is the smallest of the seven continents and is entirely surrounded by water. It has a total area of 7,688,287 km2 (2,968,464 sq mi), making it the sixth-largest country in the world and the largest in Oceania. Australia is the world's flattest and driest inhabited continent. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, including deserts in the interior and tropical rainforests along the coast.
The ancestors of Aboriginal Australians began arriving from Southeast Asia 50,000 to 65,000 years ago, during the last glacial period. By the time of British settlement, Aboriginal Australians spoke 250 distinct languages and had one of the oldest living cultures in the world. Australia's written history commenced with Dutch exploration of most of the coastline in the 17th century. By the mid-19th century, most of the continent had been explored by European settlers and five additional self-governing British colonies were established, each gaining responsible government by 1890. The colonies federated in 1901, forming the Commonwealth of Australia.

It has a diverse climate and landscapes including mountains
Australia is a country and continent with diverse geography, landscapes, and climate. It is the smallest continent in the world and the sixth-largest country. It is surrounded by the Indian, Pacific, and Southern Oceans, and various seas including the Timor, Tasman, Coral, and Arafura seas. Australia has the largest area of ocean jurisdiction of any country on Earth.
The geography of Australia is extremely diverse, ranging from snow-capped mountains to large deserts, tropical and temperate forests, grasslands, heathlands, and woodlands. The country can be divided into four major landform regions: the Coastal Plains, the Eastern Highlands, the Central Lowlands, and the Western Plateau. The Eastern Highlands, also known as the Great Dividing Range, is the most substantial mountain range in the country and the third-longest land-based range in the world. It includes the Victorian Alps, which constitute the coldest climate in Victoria, with average maximum temperatures of less than 9 °C (48 °F) in winter and below 0 °C (32 °F) in the highest parts of the ranges.
The Snowy Mountains region in the southeast falls into the alpine climate or subpolar oceanic climate zone, with cool to cold weather all year round and heavy snowfalls in the winter and spring. The western half of the continent is occupied by a desert plateau that rises into barren, rolling hills near the west coast. The Hamersley Range, the MacDonnell Ranges, and the Musgrave Range are other notable mountain ranges in the western part of the country.
The Australian landscape is also characterised by its unique natural landmarks, including the Great Barrier Reef, the Blue Mountains area, Kakadu National Park, Shark Bay, and Uluru-Kata Tjuta National Park, which contains the sacred site of Uluru/Ayers Rock.
Australia's climate varies widely across the country. The northern part of the Northern Territory has a tropical savannah climate with high humidity and two seasons: the wet season (October to April) and the dry season (May to September). The southern Australian Capital Territory has cool to cold winters due to its higher elevation, while Canberra experiences warm and dry summers with cool nights and thunderstorms.
Climate change is a significant issue in Australia, with rising temperatures, salinity, and desertification impacting the economy, agriculture, and public health. The country's population is highly concentrated in coastal areas that are vulnerable to rising sea levels, and existing water supply pressures will likely be exacerbated.
