Saumarez Reefs
Saumarez Reef is one of the southernmost reefs to be located in the Coral Sea Islands and part of the Coral Sea Shelf; it contains three main reefs and numerous smaller reefs all of which form a large crescent-shaped formation open to the northwest, about 27 by 14 km, area less than 300 km².
There are two sand cays: North East Cay and South West Cay.
The reefs were first seen on 27 of February 1823 by Lieutenant John Lihou aboard the vessel HMS Zenobia and named after Vice-Admiral of the United Kingdom James Saumarez, 1st Baron de Saumarez.
