Short summary
The Leeuwin Current to the west of Australia steers the heat exchange between the tropical and the subantarctic ocean areas. Its prominent variability during the last glacial effectively shaped the Australian ecosystem and was closely related to the dynamics of the Antarctic Circumpolar Current. At ~ 43 ka BP, the rapidly weakening Leeuwin Current, the ecological response in Australia, and human interference likely caused the extinction of the exotic Australian megafauna.
