FOR a continent not renowned for volcanic activity, Australia has some interesting volcanic landscapes. We have the Cosgrove hotspot track, the longest volcanic chain in the world running 2000km from Queensland to Victoria, and Undara in Queensland boasting some of the largest lava tubes in the world. There are hundreds of volcanoes, all are extinct and some possibly dormant, at least on the mainland. Australia’s active volcanoes are located only on the Antarctic Territory Islands, with the volcano Big Ben erupting in May this year. The last eruption on the mainland is thought to be around 5000 years ago at Mt Gambier and the next one is estimated to be at least that far away.
Some volcanic areas such as the Glasshouse Mountains in Queensland and the Warrumbungles in NSW have distinct remnants of ancient volcanoes, but many are rounded hills
