The WA Division has published a number of excursion guidebooks. Most are no longer available in hard copy, but scanned versions may be downloaded below as PDF files.
Guidebook No. 2 (Rottnest Island) is jointly published by the GSA and the Geological Survey of Western Australia. It can be also downloaded here, along with a range of other geotourism-related books produced by the WA Government.
Hard copies of Guidebook No. 2 may still be available for purchase through the WA Department of Mines and Petroleum bookshop, the Rottnest Island Authority or the University of Western Australia Geology Museum.
