Sandy Island or Ile de Sable is an island, supposedly located between Australia and New Caledonia, that existed on Google's 2012 world maps and some editions of the Times Atlas of the World. On Google's map, it was 26 km long and 6 km wide. It does not exist.
On November 22, 2012, numerous news agencies reported on an expedition by the University of Sydney, prompted by navigational charts showing water to a depth of 1400 feet at the local rise of the continental shelf where the island supposedly lies. The Landsdowne Bank is meant to have a feature called Nereus Reef in its very north, and the sea bed depth information shows the Sandy Island area as the shallowest water there.
