What is the main mountain range in Australia?

The Great Dividing Range is the main mountain range in Australia, stretching along the eastern coast of the continent from Queensland down to Victoria. This significant geological feature plays a crucial role in the country's geography, influencing weather patterns and fertility in the regions it traverses. The range is characterized by a series of mountains and plateaus, making it the longest mountain range in Australia. It serves as a watershed, separating the inland rivers from those flowing to the east coast, which is vital for both natural ecosystems and agricultural activities.

While the Flinders Ranges and the Snowy Mountains are notable mountainous regions, they do not encompass the extensive area or the geographical influence that the Great Dividing Range has across Australia. The Australian Alps, located within the broader Great Dividing Range, are also known for containing the highest peaks in the country but are just a part of this larger range. Hence, the Great Dividing Range stands out as the primary and most significant mountain range in Australia.
