Volcanex International Pty Ltd is an Australian micro-consultancy for the commercial activities of volcanologist Dr Graeme Wheller.

Dr Wheller received a BSc(Hons) from the Australian National University in 1982 and a PhD from the University of Tasmania in 1987. His subsequent geoscience career mainly involved the application of volcanology to mineral and geothermal energy exploration in Indonesia, Southwest Pacific island countries and Italy.

In 2018 his focus shifted to the development of apps to improve awareness of the potential hazards of active volcanoes, as well as their history and tourist attractions.
