Description: 2021 Australia's Volcanic pastMint Unhinged Strip of 4 Booklet Stamps OverviewVolcanoes form where molten rock (magma), typically produced in the Earth’s mantle, rises to the surface. Although there are no active volcanoes on the Australian continent, over the last 40 million years much of eastern Australia has been subject to episodic volcanic activity, the most recent being around 5,000 years ago at Mount Gambier, South Australia.This issue features three extinct volcanoes on the Australian mainland and one now comprising an offshore island. The Stamps$1.10 Table Cape, TasmaniaTable Cape, near Wynyard in north-western Tasmania, lies in the traditional lands of the Tommeginer people. Rising dramatically 170 metres from the sea, this basalt landform is a remnant plug of an extinct volcano that last erupted around 12 million years ago. The flattened top was formed from a hardened lake of lava.

The caldera or large volcanic crater surrounding Wollumbin Mount Warning is one of the best examples in the world of an erosion caldera. The mountain is a significant sacred site for the Bundjalung people.

Originally 30 kilometres in diameter, the crescent-shaped island is now much reduced to just 14.55 square kilometres and dominated by two basalt peaks, the remains of lava flows that once filled a large volcanic caldera. The world’s largest volcanic stack, Ball’s Pyramid, which lies 20 kilometres south-east of the island, is a remnant of a vent of the same volcano.
