Thunder Cave is in the Port Campbell National Park on the Shipwreck Coast, which is the final section of coastline along the Great Ocean Road.
Thunder Cave was formed after millions of years of erosion from the Southern Ocean smashing into it.
About 20 million years ago, this entire area was a deep ocean. Sand from the rivers, fish and plant matter and other debris compacted at the bottom of the ocean and formed the Sandstone and Limestone coastline that is there today.
Originally, the erosion created an arch way before the cave. Eventually, the arch collapsed, now huge bits of Limestone and Sandstone sit just outside the cave at around 15 metres below the water surface. The water pushes over these huge chunks of stone and form waves that crash into the cave, contributing to the harrowing thunder that’s created a few times per minute on a wild day.
