Monday, May 18, 2026



18 May 2026

Who does this notice affect?

This notice affects importers of live plants (nursery stock), customs brokers and departmental staff.

What has changed?

The department continually monitors scientific literature for emerging biosecurity risks. This ensures that risk management measures remain aligned with current information, and conditions remain effective in managing the biosecurity risks posed by imported commodities. 

By managing biosecurity risks associated with plant diseases, we can help protect Australia's agricultural sector, unique environment, and food supply.

Enhanced regulatory measures listed below will apply to live plants (nursery stock) that are accompanied by a phytosanitary certificate issued on or after 17 June 2026.

Consignments of plants that are certified on a phytosanitary certificate prior to 17 June 2026 will be permitted entry under current conditions.

1. Phytophthora ramorum (Sudden Oak Death)

Current measures for Sudden Oak Death will be extended to the following plant genera:

LysimachiaOxalisPolystichum

Measures for Sudden Oak Death include:

  • country freedom certified on phytosanitary certificate, or

Impact on import permits and permit applications

The department will contact affected import permit holders to vary existing permits in line with the above changes, at no cost to permit holders. 

To reduce impacts to import permit holders, permits affected by multiple policy changes will be amended only once where possible.  The department will vary all affected import permits prior to 17 June 2026.

As we transition to the enhanced measures, there may be delays to issuing new import permits for affected plant species. 

We understand that changes can be disruptive for importers and will work closely with stakeholders to minimise impacts to trade where possible. Permit applicants are encouraged to provide information to Plant Import Operations (contact details below) on their import plans to assist with this process.
