Whats the name of the reefs halfway between Oz and NZ where all them wrecked ships are parked. Think it were Ben Cropp who did a doco out there diving amoungst all the wrecks on the pristine reefs. No mention of any oil cleanups out there...
Edit; found a ref - "...at least 32 vessels are known to have been wrecked on the reefs; 17 on Middleton Reef and 13 on Elizabeth Reef. Some authorities believe the real figure may be as high as 90..." Considering the small size and isolation of these reefs its probably a good study of what happens to a reef after a shipwreck.
