(1) – (4)  The Department of Biodiversity, Conservation and Attractions (DBCA) does not undertake landscape scale asbestos monitoring in Karijini National Park. Naturally occurring asbestos is present within the gorge systems of Karijini National Park and risk signage is in place to inform visitors of the presence of the naturally occurring asbestos and safety precautions.
DBCA is aware of two studies that included monitoring for asbestos in Karijini National Park. The Wittenoom Airborne Asbestos Study conducted in 1986 which is publicly available. In addition, a preliminary site investigation was undertaken by DBCA in the Dales Gorge area in 2024. The outcomes of this site investigation were provided to the Department of Water and Environmental Regulation who determined that the site did not meet the criteria to be classified as contaminated.
DBCA is formally aware of six former employees who had asbestos related illness.
