The Henderson Islets are a group of two adjacent small rocky islands, with a combined area of 0.41ha, in south-eastern Australia. They are part of Tasmania’s Trefoil Island Group, lying close to Cape Grim, Tasmania's most north-westerly point, in Bass Strait.
The islet form part of the Hunter Island Group Important Bird Area.[1] Recorded breeding seabird and shorebird species include little penguin, fairy prion, sooty oystercatcher, black-faced cormorant and Caspian tern.[2]
