After months of sustained advocacy by NSW Farmers and grains industry bodies across Australia, the NSW Government has agreed to delay implementation of the new phosphine workplace exposure limits until 1 July 2028.
Originally scheduled to commence on 1 December 2026, the revised limits had raised serious concerns about their practical implementation, particularly during the peak grain harvest period.
NSW Farmers President, Rebecca Reardon, said the decision provided much-needed certainty for growers and valuable time to develop practical, evidence-based approaches to managing phosphine exposure.
"This has been a genuine whole-of-industry effort, with stakeholders across the country, including GrainGrowers, GrainCorp and Grain Trade Australia, working collaboratively with NSW Farmers to secure this result," Ms Reardon said.
"Introducing these changes on 1 December would have created enormous uncertainty in the middle of harvest, when millions of tonnes of grain are expected to move off farms and towards ports across NSW.
"For growers who have already endured a tough year, the consequences could have been significant.
"While industry has consistently called for a three-year extension, this delay provides much-needed certainty during harvest and an opportunity to work with government, regulators, industry and the Grains Research and
Development Corporation on a practical pathway forward.
"Worker safety is paramount, and growers take it extremely seriously. This additional time must be used to build a robust Australian evidence base and develop clear, practical guidance to support the revised exposure limits."
Essential for grain production and market access
NSW Farmers Grains Committee Chair, Adrian Roles, said phosphine remained an essential tool for protecting stored grain, maintaining quality and meeting domestic and international market requirements.
"Phosphine plays a critical role in keeping stored grain free from insect pests, maintaining grain quality and protecting Australia's biosecurity and export market access," Mr Roles said.
"Many international markets require grain to meet strict phytosanitary standards, and phosphine treatment is an important way of achieving those requirements.
"The reality is there is currently no practical alternative capable of doing this job at the scale required on farms and across the Australian grains industry.
"This delay gives us the opportunity to ensure the revised requirements are supported by sound Australian research, reliable exposure measurement methods and practical controls that can be implemented safely throughout the grain supply chain.
"Industry is already working with the Grains Research and Development Corporation on research into phosphine exposure, its behaviour in stored grain, exposure monitoring and the operational practices needed to meet the revised limits.
"The priority now must be turning that research into practical solutions that protect workers while ensuring growers can continue to safely store, protect and market Australian grain."
