Which landscape in Australia receives the least rainfall?

The Central Lowlands in Australia are known for their relatively low rainfall compared to other geographical features. This vast region, which includes parts of Queensland, the Northern Territory, and New South Wales, is characterized by its flat terrain and is located away from coastal influences that typically bring precipitation. The climate here is often arid or semi-arid, contributing to lower rainfall amounts.

In contrast, the Coastal Plains experience higher rainfall due to proximity to the ocean, which gathers moisture and leads to precipitation. The Eastern Highlands, being elevated, can also receive substantial rainfall, especially in mountainous regions where orographic lift occurs. The Cenotaph Zone, while not specifically defined, often refers to areas with limited vegetation and can also indicate drier conditions depending on the broader geography. However, the Central Lowlands stand out distinctly as the region associated with the least annual rainfall, affirming its recognition in the context of Australia's diverse landscapes.
