Which landscape in Australia is home to the largest cities?

The coastal plains are home to Australia's largest cities due to their favorable geographic and environmental conditions. This region typically features flat or gently sloping terrain that is conducive to development and urbanization. The coastlines provide access to trade routes, fishing, and tourism, which are significant economic drivers for cities. Additionally, the milder climate along these coastal areas makes them attractive for living and working, leading to higher population densities in cities such as Sydney, Melbourne, and Brisbane.

In contrast, the inland desert, mountain ranges, and plateaus are less conducive to large-scale urban development. The arid conditions of the inland desert limit agricultural and industrial opportunities, while mountain ranges often present challenges for infrastructure and expansion. Plateaus, although they can be flat, are typically found in more remote areas with limited access to major resources and trade routes, making them less favorable for large cities.
