From devastation to wonder as Kangaroo Island bushfires lead to cave discoveries

Devastating bushfires in 2019-2020 unexpectedly led to the discovery of numerous subterranean environments. The clearing of dense vegetation following the inferno allowed researchers to use aerial imagery to spot depressions indicating potential openings. Speleologists, exploring based on the island's geology, found over 150 previously unknown caves, significantly increasing the known count.

One major find was named Phoenix Cave, notable for its extensive limestone formations. These caves are estimated to be one to two million years old, offering insights into past climate conditions through the analysis of stalactite rings. Explorers also documented new cave-dwelling life, including several potentially new, eyeless spider species adapted to subterranean existence. While the newly found sites remain closed to the public, the discoveries highlight unique ecological and geological resources, symbolizing a form of rebirth following the extensive fire damage.
