Councillor Island, part of the New Year Group, is a granite island located in the Bass Strait, lying off the north-west coast of Tasmania, Australia.
There are four islands in the New Year Group. Besides Councillor Island, these are:
While King Island has the largest area of the four islands, the group is named after New Year Island because it was discovered by Europeans a few days earlier than King Island.
Breeding seabird and shorebird species include little penguin, short-tailed shearwater, fairy prion, common diving-petrel, Pacific gull, silver gull, sooty oystercatcher, black-faced cormorant and Caspian tern. Reptiles include eastern blue-tongued lizard.
The island forms part of the King Island Important Bird Area because of its importance for breeding seabirds and waders.
