On 5 August the department published the updated methyl bromide fumigation methodology (version 3.0), set to take effect on 1 May 2025.

This update is important for treatment providers to understand and implement the new requirements.

The changes follow an extensive review period from stakeholders. The updated version removes ambiguous language and includes simplified wording and clarifies requirements. This is to ensure treatment providers meet the requirements and apply fumigations correctly.

?While there are minor changes made to treatment requirements and processes, there are no changes to how a successful methyl bromide fumigation is performed.

Australia is a signatory to the Montreal Protocol and committed to biosecurity and environmental protection. We acknowledge that methyl bromide is an ozone-depleting gas. By following our new methodology, fumigators can ensure correct and responsible application of fumigations, reducing wastage and the need for retreatments while upholding the highest standards of biosecurity. Adhering to these updated guidelines will help safeguard the ozone layer and protect Australia's environment.

The Methyl Bromide Fumigation Methodology is an internationally recognised standard for the application of methyl bromide. Members of the International Cargo Co-operative Biosecurity Agreement (ICCBA) have endorsed the methodology, harmonising treatment requirements internationally.
