Plant and Plant Products Import Requirement Changes

​​​​​​​​​​The Plant Biosecurity Manual Tasmania, is published in December of each year, as a new ​edition for the coming calendar year.

Occasional changes to Import Requirements need to be made at short notice. This page contains notifications of any such changes that are introduced outside of the annual edition of the manual.

Note: All Import Requirement updates throughout 2020 have been replaced or superseded by the new edition of the Manual.

Revocation of Import ​Requi​​​​rement 31(IR31) Hosts and Vectors - Citrus Canker (Xanthomonas citri subsp. citri Gabriel et al.)

Citrus canker is a contagious plant disease that affects citrus plants including lemon, lime, mandarin, grapefruit as well as some native plant species.

In April 2018, citrus canker was detected in the Northern Territory (NT) and subsequently Western Australia (WA) in May 2018. Citrus canker had previously been declared eradicated from Australia in 2009 following an outbreak in Queensland.
Australia has once again been declared officially free from citrus canker with the lifting of remaining restricted areas in the NT from 12 April 2021, with restricted areas in WA lifted earlier.

As a result of this declaration, Tasmania has now revoked Import Requirement 31 (IR31) Hosts and Vectors - Citrus Canker (Xanthomonas citri subsp. citri Gabriel et al.) with effect from 19 April 2021.
The disease declaration has also been revoked from List A Diseases – Bacteria

Minor change to Import Requirement 5 (IR5) – Fruit Fly Host Produce – Hard Green or Similar Condition.

Import Requirement (IR) 5 in the Plant Biosecurity Manual Tasmania is a fruit fly host produce IR allowing conditional entry to certain produce in a hard green (or similar) condition for several types of fruit, including 5 varieties of avocado.

Biosecurity Tasmania has had cause to consider whether avocados could also be imported into the State under the same  arrangements currently approved for bananas, and continue to satisfy the State’s ‘Appropriate Level of Protection (ALOP)’ that any such produce remain free from fruit fly infestation.

Bananas have been allowed to be imported into Tasmania under an additional entry condition outlined in IR5. This additional condition has allowed mature and green bananas to be artificially ripened in a properly constructed and operated ripening chamber immediately before shipment to Tasmania, if both the chamber and export pathway post ripening remained secure and free from fruit fly.

The proposal to consider a similar entry condition for avocado was assessed by the Tasmanian Plant Biosecurity Regulatory Working Group. It was determined that avocados arriving hard into, and via, an artificial ripening chamber can occur with very low or negligible risk. IR5 (Section 1 – avocadoes) has subsequently been reworded and updated to allow for artificial ripening of hard avocadoes immediately prior to import to Tasmania.

This change came into effect from 12:00am, 17 May 2021.
