Coral bleaching on the Great Barrier Reef could result in one million fewer visitors and hundreds of millions of dollars in lost tourism revenue each year, according to a report by a Canberra-based think tank.

"The massive drop in visitors would result in the loss of one billion dollars in income, and 10,000 tourism jobs," the Australia Institute said in a report.

While many potential visitors may seek other Australian attractions, some "175,000 potential visitors may not come to Australia at all," the report said.

More than 4400 people were surveyed for the report in the United States, Britain, China and Australia, said Tom Burmester, a spokesman for the Institute.


"China, UK and US are the top three countries, making up two in five tourists visiting Australia," he said Tuesday.
