Shark Island (Port Jackson)
Shark Island is an island located within Sydney Harbour, in New South Wales, Australia. The island is 1.5 hectares (3.7 acres) in area, measuring some 250 metres by 100 metres, and lies off the Sydney suburbs of Point Piper, Rose Bay and Vaucluse, in the eastern section of the harbour between the Harbour Bridge and the harbour entrance. The island was known by the local Aboriginal people as Boambilly, and the current name comes from its shape, which is claimed to resemble a shark. Shark Island Light is an active pile lighthouse located just north of Shark Island. Its light is only visible from within the harbour’s fairway between Shark Point and Point Piper.
