What mountain range separates the coastal regions from the inland areas of Australia?

The Great Dividing Range is the mountain range that plays a significant role in Australia's geography by separating the coastal regions from the inland areas. This extensive range runs approximately 3,500 kilometers from the northern part of Queensland down through New South Wales and into Victoria. It influences both the climate and hydrology of the regions on either side of it.

On the coastal side, the range contributes to a more temperate climate with significant rainfall, supporting lush forests and agricultural activities. Conversely, the inland areas tend to be more arid and experience harsher conditions, with much less rainfall. This results in distinctly different ecosystems and human activities on either side of the Great Dividing Range. Additionally, the range is home to various national parks and is recognized for its biodiversity, making it a crucial geographical feature of Australia.
