Australian Caves and Karst Systems

John A. Webb is Emeritus Professor of Environmental Geoscience at La Trobe University, Melbourne. He has published extensively on Australian karst, particularly the Nullarbor and southeastern Australia, and has caved throughout Australia and overseas (although not so much recently). In 2013 the Australian Speleological Federation awarded him the Edie Smith Award for outstanding service to Australian speleology, and he gave an invited plenary speech on Australian karst at the 2017 International Congress of Speleology. His interests extend to geoarchaeology, including artefact and ochre sourcing, as well as the landscape evolution of archaeological sites. He also works on groundwater and contaminated site management, with an on-going research project on improving treatment procedures for acid mine drainage. He has supervised over 30 PhD and 100 honours students in a variety of geomorphological, ^5000 citations in total.

Susan Q. White is akarst geomorphologist at La Trobe University Melbourne. She has published on Australian karst developed on Cenozoic limestones (including the Nullarbor) and Proterozoic dolomites (Bullita/Judburra). She has caved extensively in Australia and overseas. In 2015 she was awarded the Order of Australia Medal (OAM) for service to science (especially speleology) and youth (Girl Guides). She chaired the ASF Publications commission from 2005 to 2019, has been involved in the Speleo2017 Congress, Conservation and Library Commissions, and was an Editor of Helictite (1998-2016).
