We discussed that on the GMT list too and no, the island does NOT
exist in the SRTM+ or GTOPO30 series<br>
<br>
See for example<br>

ship claims to have undiscovered a large island in the South
Pacific’s Coral Sea near New Caledonia, called Sandy Island.
The news feeds have picked up on this and it’s making its way
around the geeksphere with great rapidity. Here is an example
article:<br>
<a class="moz-txt-link-freetext" href="http://phys.org/news/2012-11-aussie-scientists-un-discover-pacific-island.html">http://phys.org/news/2012-11-aussie-scientists-un-discover-pacific-island.html</a><br>
<br>
However, it is quite clear from satellite imagery and multiple
data sources that the “island” in fact exists, though possibly
it is a barely submerged sandbar. Yet the crew claims depths
there are around 1,400 meters.<br>
<br>
Obviously the ship was not where they say it was. The question
is, how did the crew of this research vessel convince
themselves they were sailing in the same area? I don’t think a
datum mismatch can account for this, given the size of the
sandbar. <br>
