Great Basalt Wall is a national park in Queensland, Australia, 1124 km northwest of Brisbane. This national park protects 35,200 ha of land containing the Great Basalt Wall, a geological formation of the Toomba flow. The Toomba volcano erupted approximately 20,000 years ago, covered 670 square kilometres, and flowed for 120 km.[1][2] It is one of the most recent volcanic eruptions in Queensland. Due to the viscous nature of the rocky lava flows the park is not accessible to the public.[3]
249 animal species inhabit the park.[4] The elevation of the terrain is 498 metres.[5]
