Rainforests
Unique Flora and Fauna

These natural features contribute significantly to Australia’s identity and ecological diversity. Understanding each aspect provides insights into the country’s geographical complexity.

Mountain Ranges:
Mountain ranges in Australia, such as the Great Dividing Range, significantly influence local climates and ecosystems. The Great Dividing Range is the longest mountain range in Australia, extending over 3,500 kilometers. It separates the eastern coastal regions from the interior deserts. This range affects precipitation patterns, leading to wetter climates on the eastern side, which supports diverse ecosystems, including rainforests. Conversely, the interior is arid due to rain shadow effects, influencing agricultural practices and settlement patterns.
Coastal Areas:
Australia’s coastal areas stretch over 34,000 kilometers and significantly impact biodiversity and climate. The coast features diverse ecosystems, including coral reefs, mangroves, and sandy beaches. The Great Barrier Reef, the world’s largest coral reef system, supports thousands of marine species and is crucial for tourism. Coastal areas serve as critical habitats for various species, including migratory birds and marine life. Furthermore, these regions are often major population centers and economic hubs.
Deserts:
Australia has several deserts, including the Simpson Desert and the Great Victoria Desert. These arid regions dominate the inland areas and are characterized by low rainfall and extreme temperatures. Deserts support unique plant and animal life adapted to harsh conditions, like kangaroos and various reptiles. The presence of deserts influences land use, including grazing and mining activities. They also present challenges for water security and agricultural practices.
Rivers and Lakes:
Australia’s rivers and lakes, such as the Murray-Darling Basin, are vital for agriculture and freshwater supply. The Murray River is the longest river in Australia, crucial for irrigation in the southeastern regions. Lakes, both freshwater and saltwater, contribute to biodiversity and are often sites for recreation. Seasonal flooding and drought patterns affect water availability, impacting both the natural environment and human activity, as noted by the Australian Bureau of Agricultural and Resource Economics.
