Newer Volcanics Province
The Newer Volcanics Province is a complex of volcanic centres formed by the East Australia hotspot across south-eastern Australia. It has an area of 6,000 square miles (15,000 square km) with over 400 vents and contains the youngest volcanoes in Australia. The youngest eruptions in the volcanic field took place at Mount Schank and Mount Gambier about 5000 years ago, when explosive activity formed several maars and associated lava flows.
