Tomato potato psyllid (TPP) industry advice

The updated permits (30 April 2026) replace the previous versions. Conditions have been clarified and refined to support consistent application across industry.

The updated carrier permit clarifies that some material is not considered a TPP carrier, including:

• whole plants with no leaves or green plant material,
• plants intended for immediate consumption (e.g. harvested vegetables),
• tissue culture material.

These pathways must still meet basic requirements such as traceability labelling, but do not require certification. Note that these conditions only apply to TPP carriers, and not TPP hosts such as Solanaceae and Convolvulaceae.

The updated host permit accepts pest free places of production in Western Australia and Victoria with updated monitoring parameters (PS-66 and CA-14).

The updated host permit continues to provide multiple movement options, including:

• treatment, inspection and certification, (e.g. PS-57, PS-58)
• irradiation or fumigation treatment options, (e.g. ICA-55, ICA-04)

Businesses must continue to follow the relevant pathway and certification requirements.

The updated permits also clarify how inspection must be conducted under certification pathways. Inspection must now be carried out on 2% of packages/cartons (with a minimum of 3 and a maximum of 600 units per consignment). This replaces the previous approach that required “whichever is the greater”. Businesses and certifiers should ensure they are applying this updated inspection method.

The most recent permit updates clarify how inspection must be conducted under certification pathways.

Inspection must now be carried out on:

• 2% of packages/cartons,
• with a minimum of 3 packages, and
• a maximum of 600 units per consignment.

This replaces the previous approach that required “whichever is the greater”. Businesses and certifiers should ensure they are applying this updated inspection method when inspecting consignments.

This inspection method applies to both TPP host plant material and carrier nursery stock under the relevant certification pathways.

Currently, these rules apply to Victoria and Western Australia as TPP has been confirmed in those states and present a risk for transport to NSW. The conditions allow for the risk of TPP being moved with materials/carriers to be significantly reduced.

The TPP Control Order prohibits the movement of TPP host material, carriers or nursery stock into NSW to prevent the introduction of TPP into NSW, unless a person complies with control measures.

The Group Biosecurity Permits  provide flexibility within those legal boundaries. They allow for adapted conditions based on updated pest biology and risk assessments, enabling continued interstate trade while maintaining strong biosecurity protections. Without the permits, certain movements necessary for business continuity would not be possible under the Control Order.

In short:

Control Order = baseline legal framework for TPP risk management.

Group Permit = tailored conditions that facilitate trade and compliance without compromising biosecurity.

TPP hosts are plants that the psyllid can feed on and reproduce on. Carriers include any plant material or items that can transport the pest, even if they are not hosts. Under the Biosecurity (TPP) Control Order 2024, the following definitions apply:

TPP host material means any plant or cutting from the plant families Convolvulaceae or Solanaceae, excluding processed material or seeds. Nursery stock from the Convolvulaceae and Solanaceae plant families are included in this definition.

TPP carrier means:

• all other nursery stock (outside of host families Solanaceae and Convolvulaceae) which are whole plants.
• any machinery or equipment that has been used in the cultivation, handling, harvesting, processing or packaging of TPP host material
• a covering or packaging that has been in contact with TPP host material.

Common species within the Solanaceae family include capsicum, chilli, eggplant, petunia potato, tobacco and tomato. The Convolvulaceae family includes sweet potato and related ornamental varieties.

This is not a definitive list of TPP host plants. If you are unsure about the plant family of material you are moving, it is your responsibility to check before transport.

Yes. While the primary concern is TPP host plants (such as Solanaceae and Convolvulaceae species), carriers include nursery stock, which means all plants are subject to movement conditions under the Control Order. This is because whole plants can transport the pest even if they are not hosts.

Some plant material is considered very low risk and is not regarded as a TPP carrier. See FAQ "What plant materials don't require certification for TPP?" below.

Even where material is not considered a carrier, basic requirements such as traceability information can still apply.

If you are moving any plants into NSW from affected states, you must check the Order and permit requirements and ensure compliance. See the answer to “What documentation do I need when moving TPP host material/carriers into NSW?” for more information.

NSW accepts TPP Area Freedom Certificates from Northern Territory, Queensland, South Australia and Tasmania.

Whole plants

All whole plants that can carry TPP must be certified before entering NSW. WA and Vic Departments can provide advice on consignments needing a Plant Health Certificate, however NSW also accepts Plant Health Assurance Certificates from the following;

• ICA-62 is a national procedure that allows accredited businesses to treat and inspect “Nursery stock that can carry Tomato potato psyllid” under the Order. Certification under ICA 62 meets the inspection requirements of the TPP Control Order when applied in accordance with the group permit.
• Victoria’s PS-57 procedure, “Treatment and Inspection of Nursery Stock for Tomato-Potato Psyllid” provides an additional entry option for tomato, potato, capsicum, chilli, sweet potato and other similar host plants, provided they meet all treatment and inspection requirements specified under the group permit.
• Victoria’s PS-59 procedure “Treatment or Inspection or Secure Packing of carrier nursery stock for Tomato Potato Psyllid”, provides an additional entry option for nursery stock allowed under the group permit, provided that one of the conditions under clause 15(2) of the Control Order have been met.
• Western Australia’s CA-14 “Pest Free Production Site” and Victoria's PS-66 allow for host nursery stock to be certified under the Order and group permit.

Fruit and vegetables

Any whole plant intended for immediate consumption such as harvested root vegetables with tops or harvested and packaged leafy vegetables with roots such as hydroponically grown lettuce or herbs are allowed movement without certification into NSW under the group permit for carriers.

Host plant fruit and vegetables such as tomatoes, capsicums, chillies, eggplants can enter NSW if they have received an approved treatment and have been inspected to confirm they are free from TPP.

WA and Vic Departments can provide advice on consignments needing a Plant Health Certificate, however NSW also accepts Plant Health Assurance Certificates from the following for host plant material;

• ICA-04 “Fumigation with methyl bromide” is a national procedure that allows accredited businesses to fumigate host produce with methyl bromide under the group permit for host plant material.
• ICA-55 “Irradiation Treatment” is a national procedure that allows accredited businesses to irradiate host produce under the group permit for host plant material.
• Victoria’s PS-58 procedure “Treatment and Inspection of Tomato-Potato Psyllid Produce”, which allows treatment and inspection of host produce under the group permit for host plant material.
• Victoria’s PS-61 procedure “Pack-house washing and inspection of Tomato Potato Psyllid host produce”, allowed under the group permit for host plant material.
• Western Australia’s CA-15 “Pack-house washing and inspection of tomatoes without leaves, calyx or other attached green material for TPP” allows for tomatoes to be certified under the Order

Used equipment or a used covering

• ICA-66 “Cleaning and inspection of used agricultural and horticultural equipment for specified pests” is a national procedure that allows accredited businesses to clean and inspect used equipment. Plant Health Assurance Certificates are accepted from ICA-66 under the Order.

Low risk material (not considered carriers)

Under the Group Biosecurity Permit - TPP - Alternative movement control options for carriers V2, carrier material which are whole plants such as:

• defoliated plants,
• plants intended for immediate consumption, or
• tissue culture,

do not require certification, however consignments must:

• include a label or identifier stating the name and postcode of where the plants were grown and packed.

Always check the relevant permit to confirm the correct requirements before movement.

PS-62 certification is not required for dormant nursery stock as the movement of defoliated plants is covered by the updated carrier permit as outlined above.

Additionally, NSW does not require certification for certain plant products as they are not regulated as whole plants under TPP requirements.

This includes:

• Fruit from TPP carrier plants, including ICA‑60 (strawberries)
• Inspected and packaged produce from carriers, including
  • ICA‑61 (washing, inspection and secure packaging of produce from carriers)
  • PS‑60 (inspection and secure packaging of field‑packed produce from carriers)
• Host/carrier produce inspected with no green plant material, including Solanaceae and Convolvulaceae tubers
  • PS-62 (inspection for no green material)
• Other carrier (non-host) materials that are not considered whole plants, including
  • cut flowers and foliage not belonging to families Solanaceae or Convolvulaceae
  • bulbs, corms and rhizomes

These certification pathways apply to produce harvested from TPP carrier plants. Certification is not required for TPP under these arrangements because they are not whole plants.

Important

Businesses should ensure they are correctly identifying whether their material is:

• host plant material,
• a TPP carrier, or
• not regulated (alternate to ‘whole plant carriers’),

and apply the appropriate requirements.

Currently, movement through Victoria is subject to the same restrictions as movement from Victoria. You must comply with NSW entry requirements regardless of transit.

Businesses accredited under ICA-17 and ICA-57 may be able to reconsign TPP host material under the ICA conditions. Consideration will be made on a case-by-case basis. Contact plantbiosecurityapplications@dpird.nsw.gov.au for more information.

Under current NSW conditions, washing is only a viable treatment for tomatoes with no leaves, stem or calyx attached. Bagged salads containing tomatoes and no other TPP host material must be washed AND inspected in accordance with the measures in the Biosecurity (TPP) Control Order.

Processed material is exempt from these conditions. Processed material means any TPP host material that has been processed in a manner that alters the form of the TPP host material so that it is incapable of introducing tomato potato psyllid into the TPP Control Zone, including being processed by canning, chopping, cooking, drying, freezing, juicing, shredding, or slicing.

Cuttings not belonging to families Solanaceae or Convolvulaceae are permitted entry into NSW, so long as they are cut and not whole plants.

Cuttings belonging to families Solanaceae or Convolvulaceae are not permitted unless in accordance with the conditions of the Control Order or Group Permit.

Yes (excluding host plant material from the plant families Convolvulaceae or Solanaceae).

Whole plants without any leaves or green plant material are not considered TPP carriers and can be moved into NSW. However, consignments must include a label or identifier stating the name and postcode of where the plants were grown and packed.

Plants with any remaining leaves or green material are still considered carrier nursery stock and must meet full certification requirements under the Control Order or Permit.

Yes (excluding host plant material from the plant families Convolvulaceae or Solanaceae).

Plants intended for immediate consumption (for example, harvested vegetables such as spring onions, sprouts, and hydroponically grown leafy produce with roots) are not considered TPP carriers.

These consignments must include a label or identifier stating the name and postcode of where the plants were grown and packed, but do not require full certification under carrier pathways.

Yes.

Tissue culture material is not considered a TPP carrier and can be moved into NSW.

You must ensure the consignment includes a label or identifier stating the name and postcode of where the plants were grown and packed.

This is an evolving situation. Requirements may change as new information becomes available. Regularly check the NSW DPIRD website during this time for any updates.

Yes. All movements of TPP host material into NSW must comply with the permit, regardless of scale.

No. All movements of host material are regulated to prevent pest spread.
