When to Visit
While Summer is a great time for beach activity and water sports, winter is also popular because on the island, the temperatures are warmer and it often rains less than in Perth. Be careful during the summer months as you are outdoor more than not and the sun can be harsh. The one saving grace on Rottnest is that you are more likely to get a good breeze than on the mainland.
CHECK OUT THE FRIENDLY LOCALS..
When you visit Rottnest Island one of the first things you will notice are the locals.These being The Quokkas a small mammal about the size of a large cat and usually weighing about 3-5 kilograms.Usually brown in colour .First seen by a Dutch Mariner he thought them to be rats and so the Island then become known as "Rotte Nest" (Rats Nest). The national Parks and Wildlife protect these little animals and is against the law to touch or handle them in any way.They really look like a small kangaroo actually and are only found in a few locations , here and a few other outer Western Australian Islands. The Quokka population thrives here on Rottnest as they have no predators to bother them..
Rottnest has a festival in March every year. There is also an annual Cottesloe to Rottnest swim in February which is about 20 kilometres and attracts more than a thousand competitors each year.
