Climate
The climate in Rottnest Island is essentially the same as that in Perth, it may be a little cooler due to its more southern location, and because it is an island.
Understand
As almost all activities on Rottnest Island are under the administration of the Western Australian Government. It is invariably known as Rotto to the locals.
Flora and fauna
Quokkas are small marsupials which gave the island its name - early settlers mistook them for giant rats and called the island 'Rats Nest.'
Landscape
The island is sparsely covered with scrub and occasional stands of woodland, and is dominated by several large salt lakes and some low hills.
It is the bays and beaches that are the attraction on Rottnest, featuring excellent reefs and caves, for swimming, snorkeling and diving.
History
The island was used as an internment camp for Italian and German civilians in WWI.
In WWII several large artillery guns were built on the island's tallest hill. These are no longer functional, but you can take free tours to the guns and through the bunkers surrounding them.
Today the island is no longer used by the military and is a popular and relaxing getaway.
