Apart from North Keeling Island (declared a National Park in 1995 and is administered by Parks Australia), which is 30 kilometres from the main group, the Islands form a horseshoe-shaped atoll surrounding a lagoon. The people of the Cocos Keeling Islands voted to become part of Australia in 1984.
On the stamps:
- The Herald Petrel (Pterodroma arminjoniana) is a medium-sized bird belonging to the Procellariidae family. It is a sea bird and spends much of its life on or above the ocean, only really visiting nesting grounds during breeding season.
- Home Island - located across the lagoon and just a short ferry ride away, this unique part of the Cocos Keeling Islands is a must-see for visitors. Home of the Cocos Malay people, the island offers a complete contrast to West Island.
