Tasmania accepts ICA-42 for myrtle rust

2 June 2026

Summary

Biosecurity Tasmania has introduced a new import requirement (IR47) for myrtle rust (Austropuccinia psidii), which recognises ICA-42 – Nursery Freedom, Treatment and Inspection for Myrtle Rust as an approved certification pathway for myrtaceous plants.

What has changed

ICA-42 is now accepted by Tasmania, in addition to its existing acceptance by South Australia.

What this means for industry

Victorian businesses with a current ICA-42 accreditation can now use their accreditation to certify consignments of myrtaceous plants to Tasmania, provided all procedure requirements are met.

Victorian businesses must also comply with IR38 for relevant consignment to Tasmania. IR38 requirements may be met through certification under an ICA-29 Treatment of Nursery Stock for Export to Interstate Markets accreditation.

Note additional requirements may apply when consigning to Tasmania. It is the business’s responsibility to ensure that consignments meet all relevant Tasmanian import requirements.

Action for businesses

To apply for a new ICA-42 accreditation or for queries related to an existing ICA-42 accreditation, please contact your regional plant biosecurity team by telephone on 1800 878 962 or by email.
