Moondyne Cave is a karst cave in the Southwest region of Western Australia. It is located on Caves Road, eight kilometres north of Augusta.
It has a pothole entrance, a vertical extent of 26 metres, and a length of 270 metres, with some large dry chambers.[1]
Moondyne Cave was discovered in 1881 by Joseph Bolitho Johns, who had formerly been the bushranger known as Moondyne Joe.[2] It was first opened for public viewing in 1911. Guided tours ended in 1959, but it was reopened in 1992 after undergoing restoration.
