St Michaels Cave, Natural cave in Avalon Beach, Australia
St Michaels Cave is a limestone cave formed within the coastal cliffs of Avalon Beach. The entrance opens into a spacious underground chamber with multiple sections carved out by water erosion over countless generations.
In the early colonial period, Reverend John Therry envisioned the cave as a space for religious and cultural purposes. His ambition to build a church above it and a gathering space within never came to full fruition, yet it shaped how people viewed the location.
The cave takes its name from the Archangel Michael and reflects its past as a refuge for those seeking shelter. Today, visitors can observe how the location bridges the natural world with spiritual meaning.
The cave is currently restricted to visitors and requires advance permission from local authorities to enter. This protection measure exists due to rockfall risks and the need to preserve the habitat of the bat species living inside.
The cave shelters rare bat species, including Common bent-wing bats and Large-eared pied bats that breed in its dark chambers. These nocturnal mammals depend on the cave for raising their young, making it a vital refuge.
