The Sidmouth Rock is a rock islet or small island, located in the Southern Ocean, off the southern coast of Tasmania, Australia. The island is situated approximately south-east of South East Cape and is contained within the Southwest National Park, part of the Tasmanian Wilderness World Heritage Site. An erosional remnant of the Tasmanian mainland with a diameter of, the island is estimated to have separated from the Tasmanian mainland at least 15,000 years ago.[1]
The Sidmouth Rock is located approximately east of Eddystone, another islet located off the South East Cape.
The islet is frequently wave-washed and supports no land-dwelling life.[2]
Together with the nearby Eddystone and Pedra Branca islets, Sidmouth Rock constitutes the 2ha Pedra Branca Important Bird Area, identified as such by BirdLife International because it supports over 1% of the world populations of shy albatrosses and Australasian gannets.[3]
