The Bishop and Clerk Islets 55°03′S 158°46′E / 55.050°S 158.767°E lie about 33 km (21 mi) to the south of Macquarie Island. They are 60 hectares (0.23 sq mi) in area. The Bishop and Clerk Islets mark the southernmost terrestrial point of Australia (including islands) outside of the Australian Antarctic Territory, as well as the southernmost terrestrial point of the state of Tasmania. The Bishop and Clerk Islets form part of the Macquarie Island Nature Reserve, managed by the state of Tasmania. These islets are mostly barren rock less than 50 metres (164 ft) high and are geologically similar to Macquarie Island.
Macquarie Shags have been recorded nesting at the Bishop and Clerk Islets. A colony of Black-browed Albatrosses was discovered in 1965 on these islets.
