What You'll Learn
Unique flora and fauna
Australia's unique flora and fauna have been shaped by geological and climatic events over millions of years. Australia was once part of the Gondwana supercontinent, which began to break up 140 million years ago, with Australia fully separating around 30 million years ago. This long period of isolation allowed Australia's flora and fauna to evolve separately from the rest of the world, resulting in a high level of endemism. Today, more than 80% of Australia's plants, mammals, reptiles, and frogs are unique to the country and found nowhere else on Earth.
Australia's fauna consists of a diverse array of animals, with many species endemic to the continent. This includes approximately 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles. Marsupials, such as kangaroos, wallabies, wombats, koalas, and possums, are well-known examples of Australia's unique fauna. The country is also home to two of the five known extant species of monotremes, including the platypus. Additionally, Australia has a high number of venomous species, including spiders, scorpions, octopus, jellyfish, molluscs, stonefish, and stingrays.
The country's vast and varied landscapes contribute to the diversity of its flora and fauna. The Kimberley region, for instance, boasts unique terrestrial and marine ecosystems and is of cultural significance to its Aboriginal traditional owners. Conservation efforts have been focused on making it an eco-friendly cultural tourist destination. Similarly, the Tasmanian Midlands is home to over 180 rare and threatened plant and animal species, including the Tasmanian devil and the Eastern bettong (or Tasmanian rat kangaroo).
The federal Environment Protection and Biodiversity Conservation Act 1999 was enacted to protect Australia's native fauna and identify and safeguard threatened species. Over 500 national parks have been established, and various conservation programs and reserves have been created to protect the country's pristine areas. However, Australia has also experienced a significant loss of biodiversity due to human activities, including habitat destruction, the introduction of invasive species, and urban expansion. As a result, many native species are now endangered or threatened, and the ecosystem is at risk.
Additionally, Australia's subterranean fauna, though poorly understood, is believed to play a substantial role in ecosystem services. These unique communities, found in limestone caves underneath the Leeuwin-Naturaliste Ridge in southwest Western Australia, are listed as endangered due to declining water levels, groundwater pollution, and the introduction of species such as yabbies.

Ancient landscapes
Australia is home to some of the world's most ancient landscapes. The foundation of Australian landforms was laid during the Precambrian and Paleozoic time, around 4.6 billion to 252 million years ago. This makes the continent one of the oldest on Earth, earning it nicknames like "the Oldest Continent" and "the Last Frontier".
The landscape of Australia has remained relatively unchanged for thousands of years, with the Outback, for instance, maintaining its ecosystem from 5000 years ago. This is partly due to the continent's geographical isolation, which has shielded it from the influences that have shaped other regions, such as Europe and North America, in the last 25,000 years.
The Australian Outback is a vast expanse of rugged terrain, baking sun, and unique fauna. It is one of the most natural regions in the country, with an ecosystem that has remained largely untouched. The Outback is located in the middle of the continent, away from the coasts, and is characterised by its arid climate and sparse rainfall.
Australia's natural landscapes are incredibly diverse, ranging from pristine coastal areas to lush rainforests and red deserts. The country is home to 10% of the world's biodiversity, including numerous native plants and animals found nowhere else on Earth. The country's national environment reserve system covers 19.74% of its land mass, encompassing a range of habitats from rainforests to savannas and deserts.
The Aboriginal and Torres Strait Islander peoples, who have lived on and managed the land for over 60,000 years, have a deep connection to these ancient landscapes. Their diverse languages and philosophies form the oldest surviving culture on the planet.

Cosmopolitan cities
Australia is a highly urbanised country, with 67% of its population living in metropolitan areas as of 2018. The country's five metropolitan areas with more than one million inhabitants are Sydney, Melbourne, Brisbane, Perth, and Adelaide. Sydney and Melbourne are the two most populous cities, with over five million people each.
Australia is one of the world's most ethnically diverse nations, with nearly a quarter of its population born in other countries. People from the United Kingdom, other European countries, China, Vietnam, North Africa, and the Middle East have made Australia their home. The country also has one of the highest foreign-born populations in the world. Its culture is diverse, and its cities are cosmopolitan, bustling with activity without feeling overcrowded.
The country's cities are known for their world-class universities and colleges, attracting students from across the globe. They offer a unique blend of cultural diversity and a high quality of life, making them attractive destinations for students and professionals alike. The cities showcase Australia's cultural diversity, with a wide range of cuisines, arts, and lifestyles on display.
The 1980s were a pivotal decade in the emergence of a new cosmopolitan sensibility in Australia. The country's food habits, such as the increasing popularity of pasta and the shift towards healthier options, reflected this change. Drinking habits also evolved, with a growing appreciation for wine, marking a departure from the country's traditional association with beer.
Australia's post-war period was marked by a significant influx of Europeans, broadening the nation's cultural horizons. American pop culture and cinema also made their way into Australian society, with country music and rock and roll gaining popularity. The Hawaiian sport of surfing was embraced, building upon the existing beach culture and the local surf lifesaving movement. These influences shaped the country's urban centres, contributing to their cosmopolitan character.

Extreme climates
Australia is a land of extreme climates, with temperatures ranging from highs of 40°C in the central desert regions to below freezing in the higher regions of the country's southeast. The northern section of Australia has a more tropical climate, with all months above 18°C and a dry period in the winter. The inland west experiences low rainfall and hot summers, while the far north has a monsoonal 'wet' season, and the coastal strip enjoys warm subtropical conditions. The southern parts of Australia have a cooler climate, with the southeastern coastal areas experiencing winters that can be very harsh, and the highest peaks are usually covered in snow year-round.
The Kimberley region in northern Australia has an extremely hot monsoonal climate with a very long dry season from April to November. Eighty-five per cent of the state's runoff occurs in the Kimberley, but development has been hampered by violent floods and shallow soils. The southwest corner of the state, on the other hand, has a Mediterranean climate, with annual rainfall varying from 300 mm to 1,400 mm.
Australia's tropical/subtropical location and cold waters off the western coast make most of Western Australia a hot desert. A 2005 study suggested that human settlers arriving around 50,000 years ago may have contributed to the desertification of the interior. The country's vast size and varied geography result in significant climate variation across different regions.
Climate change has exacerbated Australia's extreme climates, with the continent warming by a mean of 1.4 °C on land and 1.1 °C in the oceans since consistent national records began. The rate of warming is consistent with global trends, but the effects are felt more acutely in certain regions. Australia has warmed by 1.51 ± 0.23 °C since national records began in 1910, with most warming occurring since 1950. Every decade since 1950 has been warmer than the previous decade, and Australia's warmest year on record was 2019.
The warming trend has led to an increase in extreme heat events, bushfires, droughts, floods, and longer fire seasons. Rainfall in southwestern Australia has decreased by 10-20% since the 1970s, contributing to drought conditions. Climate change has also influenced the frequency and intensity of tropical cyclones, which can cause heavy wind and rainstorms in the northern coastal areas. These cyclones can lead to flooding in drought-stricken areas, highlighting the contrast between the wet and dry regions of Australia.
