The map shows the average annual rainfall distribution across Australia. The image is divided into colour-coded rainfall zones ranging from very low in the interior to very high along the northern and eastern coastlines. The most notable feature is the stark contrast between the arid centre and the tropical north. The northern regions, particularly around Darwin and Queensland, receive over 1,500 millimetres of rainfall annually, driven by monsoon patterns. In sharp contrast, the central and western interior receives less than 250 millimetres per year, making it one of the driest inhabited regions on Earth. The southern coastal cities such as Melbourne and Adelaide fall in a moderate zone of 400 to 800 millimetres. In summary, rainfall in Australia is extremely uneven, with the highest totals concentrated along the northern and eastern coasts.
