The Moriarty Rocks, part of the Passage Group within the Furneaux Group, are a group of two major unpopulated granite rocks, and several smaller ones, with a combined area of, located in Bass Strait, south of Cape Barren Island, west of the Low Islets, and west of the Spike and Clarke islands, in Tasmania, in south-eastern Australia. The rocks are contained within a nature reserve.[1]
Sealing is reported to have taken on the rocks in December 1830.[2]
There is little vegetation on the rocks, due to them being frequently wave-washed. black-faced cormorants breed there, and they hold an important breeding colony of Australian fur seals, with up to about 1000 pups being born there annually.[3]
