Final answer:
The statement is false. Indigenous people in Australia predominantly live in urban areas and coastal regions, not just arid areas. Two main core areas on the southeastern and western coasts have the densest population in the country.
Step-by-step explanation:
The statement that Australian Indigenous people mainly live in arid areas of Australia is false. While it is true that Australia has large desert regions in its interior, the majority of the Indigenous population in Australia does not live in these arid areas. Instead, they predominantly live in urban areas and coastal regions.
According to available data, there are over 400 different groups of Indigenous people in Australia, with a total population of approximately 450,000. These groups have land claims that spread across various parts of the country, including urban areas such as Sydney.
Furthermore, the misconception of Indigenous people mainly living in arid areas ignores the fact that Australia has two main core areas where the majority of the population lives: a large core area on the southeastern coast and a small core area around Perth on the western coast. These regions have Type C climates and support the densest population in the country.
