Australia is transitioning to the Workplace exposure limits for airborne contaminants (WEL list). Until 1 December 2026, you must still comply with the Workplace exposure standards for airborne contaminants (WES list). Contact your work health and safety regulator for further information.
This document provides information on the changes that will take effect from 1 December 2026. These include:
- a decreased or increased exposure limit value
- an addition or removal of a type of exposure limit
- merging or splitting of groups of airborne contaminants
- addition or removal of an airborne contaminant listing.
This document is limited only to WEL that are new or changing on 1 December 2026. It is not a full list of all chemicals subject to a WEL. For the comprehensive lists, consult the WES (for current standards) and WEL (from 1 December 2026).
