Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known. This project will determine the age of desertification in Australia, thereby enhancing our understanding of such processes and the response of our landscape to changing climate.

今天的澳大利亚是最干燥的有人居住的大陆，但情况并非总是如此。几千万年前，澳大利亚的气候相当湿润。然后，几百万年前，澳大利亚的干旱发展产生了我们今天看到的红色中心的大部分沙漠特征。然而，我们的沙漠和其他干旱特征的年龄并不为人所知。该项目将确定澳大利亚荒漠化的年龄，从而提高我们对这种过程以及我们的地貌对气候变化的反应的认识。
