TPP Import Changes

Written By Brian Cooney

The Tomato Potato Psyllid insect

We wanted to provide you with a quick update regarding recent changes to Tasmania’s interstate import requirements relating to Tomato Potato Psyllid (TPP).

These updated controls are designed to protect Tasmania’s biosecurity status and now impact a range of host and carrier produce lines entering the state from certain mainland growing regions.

What is Tomato Potato Psyllid (TPP)?

TPP is a small insect pest that attacks a range of fresh produce, particularly within the tomato, potato, capsicum, chilli and eggplant categories, as well as some leafy and herb lines considered “carrier” products.

TPP is a serious biosecurity threat as it spreads a plant disease known as zebra chip, which can significantly reduce crop quality, yield and shelf life.

TPP has been detected in:

  • Western Australia (since 2017)

  • Victoria (detected in recent months – TPP-free status removed as of 8 December 2025)

Tasmania, Queensland and South Australia currently remain TPP-free, which is why strict import controls are in place to protect local production.

Host & Carrier Product Categories (High-Level Guide)

Primary Host Products (Higher Risk):

  • Tomatoes (all varieties)

  • Potatoes (Sweet Potato)

  • Capsicum / Peppers

  • Chillies

  • Eggplant

Secondary Host / Carrier Products (Regulated):

  • Baby leaf mixes

  • Spinach

  • Rocket

  • Lettuce (all varieties)

  • Asian leaf (bok choy, choi sum, gai lan, etc.)

  • Fresh herbs

  • Green vegetables

What this means for supply

We are working closely with all suppliers to ensure:

  • All applicable produce meets the required treatment and certification standards

  • Supply continuity is maintained wherever possible

  • Full compliance with Biosecurity Tasmania requirements at all times

However, as these changes are implemented across the supply chain, there may be some short-term supply disruptions on certain host and carrier products, while alternate growing regions, certifications, treatment pathways and logistics are finalised.

Cost, quality and shelf-life impacts

For produce that now requires mandatory treatment prior to entering Tasmania, there may also be:

  • Increased input and freight costs, which may place upward pressure on pricing

  • Potential quality and shelf-life implications, depending on the treatment method required

We are actively monitoring these factors and will continue to work with our suppliers to minimise any impact on our customers.
