I visited Ningaloo reef in 2005. It was beautiful and one of a kind. It should make the list just for the "Ayers rock" brain coral. But its also in the path of migratory animals like dolphins, manta rays, humpback whales, and dugongs. Then there are the whale sharks that pass through. Then there is the bush surrounding the area that lends its own beauty with wildflowers, termite mounds, and the occasional gorge.
