Mewstone
Mewstone is an unpopulated island, composed of muscovite granite, located close to the south coast of Tasmania, Australia. The island has steep cliffs and a small flat summit and is part of the Pedra Branca group, lying southeast of Maatsuyker Island, and off the south coast of Tasmania. Mewstone comprises part of the Southwest National Park and the Tasmanian Wilderness World Heritage Site.
The highest point of the island is approximately above sea level. Mewstone has abundant bird life and has been identified by BirdLife International as an Important Bird Area (IBA) because it supports over 1% of the world populations of shy albatrosses and fairy prions.
