The Bellona Platform is a submarine geological feature encompassing the Chesterfield Islands () and Bellona Reefs () west of New Caledonia. It was once a landmass, which became mostly submerged when sea levels rose at the end of the Last Glacial Maximum, 20,000 years ago. It might have played a role in the spread of flora and fauna, including humans, in the southwest Pacific. References Former islands Geography of New Caledonia Plateaus of the Pacific Ocean Coral Sea
