Rottnest Island is an island about 20 km off the coast of Perth with a permanent population of around 300 people. It receives around 500,000 visitors a year, and up to 15,000 visitors at a time during peak periods.
Almost all activities on Rottnest Island are under the administration of the Western Australian Government. It is invariably known as Rotto to the locals.
Quokkas are small marsupials which gave the island its name - early settlers mistook them for giant rats and called the island 'Rats Nest.' There are also many birds on the island and many forms of sea life in the surrounding waters.
