But there are fears they could be targeted by illegal fishing boats meeting the growing Asian demand for shark fins, used to make soup and in other products believed to have medicinal benefit.

“WWF and the tourism industry are very concerned that illegal fishers will raid the Coral Sea reefs – mainly for shark fins for the Asian market,” said Richard Leck, WWF’s marine policy manager.

“The Coral Sea presents us with a unique opportunity to safeguard one of the world’s few remaining pristine marine regions.”

The tropical ocean, between Australia and the south-west Pacific, was also under threat from future plans for undersea oil and gas extraction, WWF Australia said.

The Coral Sea was recently nominated by Forbes magazine as being one of the world’s top 10 diving destinations. Its pristine reefs and coral cays are estimated to bring in more than
