Commencing in 1988, two low mangrove islands, Andys Island and Griffin Island, were redeveloped by Lewis Land Corporation to create a six-island group for a gated community of canal home sites with deepwater moorings and direct access to Moreton Bay. of sand was pumped to create the islands and their navigable waterways. Andys Island and Griffin Island were thought to be named after local oystermen. The names of the former islands were replaced with the name Sovereign Islands in the official
place names of Queensland on 16 February 1987, despite one objection to the loss of the historic names. Sovereign Islands is one of the most expensive areas in the country with some homes in excess of 20 million dollars. Many houses do not slide under the two million dollar mark. The
2008 financial crisis impacted on real estate prices on the Sovereign Islands. In 2011 several properties sold well below prices recorded in previous years. == Amenities ==
