Rottnest Island is a popular holiday destination located 18 kilometres west of Fremantle, Western Australia. This sandy, low-lying island sitting on a base of limestone was separated from the mainland about 7000 years ago, when sea levels rose. Many localities on the island preserve features that document this recent geological history.
GSWA has produced a new pamphlet called Rottnest Island, a geology guide. This guide leads readers and visitors to Rottnest to view some world-class geology.
Guidebook to the geology of Rottnest Island by Phillip E Playford is a handy field guide to key geological localities on Rottnest Island. The book is of interest not only to professional geologists, but also to teachers, students and members of the general public who wish to learn something about the geology while holidaying on the island.
