# Australian phosphine exposure limit implementation delays > Developing situation record from CLSTR: https://clstr.news/situations/australian-phosphine-exposure-limit-implementation-delays > Updated: 2026-11-06T03:17:48.000Z. Sources: 5. Developments: 2. Several Australian states have announced delays to the implementation of revised workplace exposure limits for phosphine, a chemical used to protect stored grain from pests. The proposed changes by Safe Work Australia aim to reduce the eight hour exposure limit from 0.3 parts per million to 0.05 parts per million. Industry bodies, including NSW Farmers and GrainGrowers, expressed concerns that the original December 2026 deadline would coincide with peak harvest periods and create significant uncertainty. There are also concerns that the new limits could make the chemical practically unusable within grain storage networks. Implementation timelines vary by state. New South Wales and South Australia have implemented 18 month delays. Western Australia, Queensland, and Victoria have committed to three year extensions to allow the supply chain to develop compliance solutions and explore alternative grain protectant products. ## Timeline ### 2026-11-06: Australia delays new phosphine workplace exposure limits Australian mainland states have delayed new workplace exposure limits for the grain protectant phosphine to allow the industry time to develop compliance solutions and alternative products. 3 sources. https://clstr.news/cluster/australia-delays-new-phosphine-workplace-exposure-limits ### 2026-11-01: Australian states delay phosphine exposure limit implementation Australian states, including NSW and Western Australia, have delayed new phosphine workplace exposure limits to allow the grain industry more time to prepare for practical implementation. 2 sources. https://clstr.news/cluster/australian-states-delay-phosphine-exposure-limit-implementation --- Cite as: Australian phosphine exposure limit implementation delays.
