About this site
Rottnest Island sits off the coast of Western Australia, a short ferry ride from Fremantle at the entrance to Fremantle Harbour and the Swan River. The waters around the island are dotted with reefs and limestone reef systems shaped by the Indian Ocean swell, and numerous shipwrecks from the colony's shipping era lie scattered along its coastline.
