East Island is an island within the Lacepede Islands group, which sits about 30 kilometres (20 mi) off the coast of the Dampier Peninsula in north-west Western Australia. It is located at -16.9°N 133°W. It is the site of the East Island Lighthouse. It forms part of the Lacepede Islands Important Bird Area (IBA), so identified by BirdLife International because of its importance for breeding seabirds.[1]
East Island was originally named Grant Island by 19th century guano miners, after US President Ulysses Grant.[2]
