The Oyster Rocks are a close pair of small granite islands with a combined area of about 6 ha in south-eastern Australia.
They are part of Tasmania's Tin Kettle Island Group, lying in eastern Bass Strait between Flinders and Cape Barren Islands in the Furneaux Group.
[1] The islands are part of the Franklin Sound Islands Important Bird Area, identified as such by BirdLife International because it holds over 1% of the world populations of six bird species.
[2] Recorded breeding seabird and wader species are little penguin, short-tailed shearwater, white-faced storm-petrel, Pacific gull, silver gull, sooty oystercatcher, Caspian tern and Cape Barren goose.
Black-faced cormorants nest on the smaller western islet.
