The Coral Sea is one of few places home to hammerhead sharks
Conservationists are urging the Australian government to protect the Coral Sea, one of its last tropical marine wildernesses.
The sea was recently declared a "predator diversity hotspot" because of its abundant shark populations.
Campaigners fear the region could be targeted by illegal shark fishermen as well as oil and gas prospectors.
The Coral Sea comprises 780,000sq km, and borders the Great Barrier Reef off of Australia's east coast.
Environmental groups have described the Coral Sea as a stunning blue water highway full of oceanic predators.
The area is a haven for hammerhead and white-tipped sharks, as well as manta rays.
