No trip to Perth in Western Australia would be complete without a 30 minute ferry crossing to Rottnest Island. From mainland Australia take the Rottnest Express departing the Port of Fremantle or Perth CBD. A must see on anyone's journey to the West Coast of Australia. Visit the Quokka's, small marsupials found no where else in the world. First found by Dutch explorers believing they were giant rats hence where the islands name derived from. Choose to take a tour of the island by bus and be picked up at your accommodation on the mainland and dropped off later Rottnest Express makes it easy.
