GTA joined grain industry representatives in Canberra on 23 September for discussions with Safe Work Australia (SWA) and the Australian Pesticides and Veterinary Medicines Authority (APVMA) on the implementation of revised Workplace Exposure Limits (WELs) for phosphine.
SWA confirmed that it is focused on supporting industry through the implementation process. This includes developing guidance and providing businesses with information to help them understand their obligations.
GTA and Industry representatives used the meeting to outline some of the practical challenges associated with the revised WELs. These include phosphine absorption and desorption, differences between commodities and storage systems, and the potential time required for grain to reach lower concentrations.
The requirements for peak-exposure monitoring were another key area of discussion. Industry sought clarity on how measurements will be made and raised concerns about the availability and reliability of monitoring equipment. Access to occupational hygienists was also discussed, along with how regulators will interpret and enforce exceedances of peak limits.
The APVMA does not presently propose changes to phosphine labels before 1 December 2026. SWA and the APVMA intend to issue a joint statement explaining their respective positions.
Further practical guidance will also be important, particularly for growers and smaller businesses. Some may have limited access to specialist expertise, monitoring equipment and respiratory protection.
Research forms another part of the work underway. GTA and GRDC outlined complementary programs examining exposure on farm and post-farm-gate. The research also covers monitoring and measurability, health evidence, and the economic and operational effects of the revised WELs.
Next steps
SWA will provide draft guidance material for GTA and industry to review. This will include consideration of high-risk tasks and the controls that may be reasonably practicable.
GTA and industry will continue to engage with SWA on implementation, monitoring and compliance. The parties are expected to meet regularly to align regulatory, research and industry work programs.
GTA’s position remains that worker protection must continue to be central. The approach must also be measurable, practical, nationally consistent and appropriate for Australian grain-industry operations.
