Mammoth Cave is a large limestone cave 21 km (13 mi) south of the town of Margaret River in south-western Western Australia, and about 300 km (190 mi) south of Perth. It lies within the Leeuwin-Naturaliste National Park and is surrounded by karri and marri forest. There have been extinct animal fossils found in Mammoth Cave.

The cave is 500 m (1,600 ft) long and 30 m (98 ft) deep. It has been known from about 1850 to European settlers of the Margaret River district, but it was not explored until 1895.^[1] Its first explorer, Tim Connelly, who was appointed caretaker of the cave, conducted tours by lamplight until 1904 when electric lighting was installed.

The cave has been studied for over a century.^[3] It has yielded fossils of Pleistocene fauna over 35,000 years old, including those of thylacines and the giant marsupial herbivore Zygomaturus.
