TypeIslandDetailsSpectacle Island is at the entrance to Mooney Mooney Creek. The name is often said to be connected with the view from the summit but a more likely origin is the lens-like shape of the island, as with the island of the same name in Sydney Harbour. The name was in use prior to 1840 as George Peat's nearby land grant was said to be opposite Spectacle Island. A land Department map of 1898 shows that it was declared a reserve on 16 April, 1962.
