Xylella fastidiosa and Sudden Oak Death hosts for use as nursery stock

Effective from 3 August 2020

The following plant genera imported as nursery stock are now subject to additional measures to manage the risk of the bacterial pathogen, Xylella:

These changes apply to all permitted species for the above genera, and consignments that are exported to Australia on or after 3 August 2020.

Who does this notice affect:

Importers of nursery stock, customs brokers and departmental staff.


Xylella is Australia’s top priority plant pathogen as it has the potential to severely impact our agricultural and horticultural industries and the environment. In addition to having a large host range, Xylella is easily spread by sap-feeding insects and the propagation of infected plants.

Since emergency measures were introduced in 2015, the department continues to review the application of existing conditions to ensure that they are fit-for-purpose and effective in managing biosecurity risks. Import conditions are being revised to ensure that emergency measures are appropriately targeted to the original list of 89 regulated plant families.

The department will continue to monitor and assess evidence of new risks posed by Xylella and may amend import conditions again in the future.
