Undara Lava Tubes were formed about 190.000 years ago, when Undara Volcanoe - the major crater in the McBride Volcanic Province - erupted. Its molten lava was flowing down a dry river bed and soon formed a Speleologylava tube. As the eruption stopped, the lava drained out of the tubes leaving a series of long tunnels.

The word "Undara" is an Aboriginal word meaning "a long way", and actually one of the lava flows from Undara extends 160 kilometers making it the longest known single lava flow on Earth. Another tube - formed by part of the flow - extends for more than 100 km and several sections are accessible.

During the eruption cycle, the Undara volcano spewed forth 23 km³ of lava covering 1550 km². So far, 68 separate sections of cave have been identified from over 300 lava tube roof collapses.
