- an import permit is required to import the following seed species imported for sowing purposes:

- imported seed must be grown and disease screened for a minimum of 12 months, at the Australian Government post-entry quarantine (PEQ) facility at Mickleham, Victoria. Before release from biosecurity control, the plants must be tested and found free from Xylella species.
- All other import conditions will continue to apply, including mandatory phosphine or cold treatment to mitigate the risk of insect pests.
Next steps:
