This study will advance our knowledge of the most remarkable floods ever known to have occurred in Australia. They were associated with a vast aquatic ecosystem in what today is the barren northern end of the Flinders Ranges, a region of desert dunes and salt lakes. Remarkably, such wet conditions appear to have coincided with episodes of megafaunal extinction and with the human occupation of Australia. The results will provide valuable information with which to better understand the the main global drivers of episodes of profound wetness and dryness in Australian climate.
