A beautiful WWF cover, my first one from Cocos (Keeling) Islands, depicting a complete set issued in 2005 with 2 species of sharks: the blacktip reeef shark and the Grey reef shark.
The Cocos (Keeling) Islands is a territory of Australia, located in the Indian Ocean, southwest of Christmas Island and approximately midway between Australia and Sri Lanka.
Stamps from Cocos (Keeling) Islands can be used in Australia, but this cover was really posted in the islands (local zip code WA 6799).
Reef sharks are a WWF priority species and at WWF they work to ensure such species can live and thrive in their natural habitats.
