Biosecurity Advisory 24/2024 - Nominations for the 2024 Tasmanian Biosecurity Awards are now open

​​The awards recognise outstanding biosecurity projects and represent a platform to reinforce, recognise and promote positive biosecurity behavioural change in the industry and community.

This is an opportunity to recognise those in our communities and industries who have gone above and beyond to help protect our future.

Biosecurity is foundational to the economic, social, and environmental assets of Tasmania and we all share the benefits of our strong biosecurity system.

It underpins our multi-billion-dollar agri-food production and export industries, and protects our unique natural wilderness areas that have immeasurable value to all Tasmanians and also visitors to our state.

The awards comprise of two categories, one being the Tasmanian Community Biosecurity Award and the other the Tasmanian Industry Biosecurity Award.

Last year the Tasmanian Community Biosecurity Award was won by Robyn Lewis and the Tasmanian Industry Biosecurity Award by Nic Hansen.

Robyn won for her outstanding management of biosecurity threats to the Milford Forest property, an important ecological site for a number of endemic and endangered species.

Nic was recognised for his contribution and assistance during the 2018 fruit fly incursion in Tasmania and the successful emergency response and eradication that followed.

If you or someone you know has personally contributed towards improving biosecurity in Tasmania, or if they are part of an organisation or group, you can place a nomination today.

Biosecurity Advisory 13/ 2024 - Small hive beetle response a success

​Effective from 22 April 2024, Tasmania’s small hive beetle response activities have ceased. Thanks to the success of the response, the previously declared General Biosecurity Direction (small hive beetle) and the associated Bee Movement Restriction Area (BMRA) have now been revoked.

Following the detection of small hive beetle in the East Devonport area in March 2023, Biosecurity Tasmania responded quickly, working alongside beekeepers, industry and the community to protect the health of Tasmania’s bee population as well as our honey and pollination sectors. 

Extensive surveillance activities, including thousands of beehive and trap inspections, have been ongoing within the BMRA. Biosecurity Tasmania concluded the final round of inspections in March 2024.
Biosecurity Tasmania sincerely acknowledges the cooperation from beekeepers, industry and the community during this emergency response.

Small hive beetle is a European honeybee pest that is present in all Australian states except the Northern Territory and Tasmania. All Tasmanian beekeepers are asked to remain vigilant for any signs or pests or disease, and report anything unusual to Biosecurity Tasmania on (03) 6165 3777.

Tasmanian Biosecurity Advisory 12/2024 - Restrictions on importing aquatic ‘moss balls’ into Tasmania

‘Marimo’ or ‘moss balls’ (Aegagropila linnaei Kützing) are an aquatic plant usually sold through the aquarium trade as a novelty item for fish tanks or display freshwater ponds.

Moss balls are listed as a prohibited item for import into Tasmania. They can be invasive and present a significant biosecurity threat if they were to establish in Tasmania’s natural freshwater lagoons and highland lake and river ecosystems.  

Particularly concerning is the potential that this organism can carry other very harmful, invasive organisms like didymo (Didymosphenia geminata)​. Also known as rock snot, didymo is also a prohibited import item in Tasmania. 

If you are involved in the aquarium industry as a trader, breeder, retail outlet or hobbyist, you have an important role in preventing the introduction and spread of marine pests in Tasmanian waters. 

Here are some important things to remember about being a responsible aquarium supplies provider or aquarium owner:
  • Check that you are not importing or bringing back into Tasmania prohibited plant or animal species.
  • Never release aquarium fish into any waterways.
  • Do not dispose of aquarium tank water or sick fish into stormwater or street drains.
  • Ensure outdoor fishponds cannot overflow into creeks or into storm water drains.
  • Seek advice on keeping a healthy aquarium and if you suspect a serious disease, contact your veterinarian or Biosecurity Tasmania.
We all have a general biosecurity duty to protect Tasmanian from the adverse impacts of pests, weeds and diseases.
If you are aware of anyone selling ‘marimo’ or ‘moss balls’ in an aquarium shop or who has them already in a fish tank or freshwater pond, please contact Biosecurity Tasmania immediately.

Biosecurity Advisory 10/2024 - Release of 2024 edition of the Plant Biosecurity Manual Tasmania

​On 29 March 2024 (Good Friday), Biosecurity Tasmania will release a 2024 edition of the Plant Biosecurity Manual Tasmania (version 1).

The new edition includes but is not limited to the following revisions:

  • Updates to the general import conditions around alternative treatment standards (see Section 2.8). Now, if importing plants or plant products under an alternative treatment standard, an Individual Permit is required. An Individual Permit is also required for product certified under a Phytosanitary Certificate.
  • To ensure imported tissue cultures meet required standards, commercial facilities must now be endorsed by Biosecurity Tasmania prior to consigning to Tasmania (see Section 2.10). A new application form will be available on the NRE website from 29 March 2024. Non-commercial operators wanting to send tissue culture to Tasmania can apply for an Individual Permit if they meet the import conditions in clause I of Section 2.10.
  • Inclusion of cacao (Theobroma cacao) as a Mediterranean fruit fly host in Schedule 1A of this Manual;
  • Incorporation of recent changes to the schedule of host products that can be treated for Queensland fruit fly with methyl bromide fumigation under Import Requirement (IR) 2. This now excludes mangoes and plums from treatment;
  • An important change to Import Requirement 10 (IR10) relating to the import of grape matter (vines and other products) from States holding Pest Area Freedom certificates for grape phylloxera. For such States, grape matter (of any form) is no longer exempt from the treatment conditions specified in IR10 for grape matter originating from any recognised Phylloxera (management) Exclusion Zone.
  • Minor changes to requirements for the import of animal feed grain (IR 30), and seed for sowing (IR 36) to bring greater clarity on what is and is not accepted as contaminants in those products, and their tolerance limits;
  • The addition of a 24-month validity period for Statement of Seed Analyses in IR36.
  • Seed weighing less than 1kg being imported for the purposes of research or trials, can no longer be imported under the small weight seed imports condition in IR36 and can only be imported with an Individual Permit.
  • Re-inclusion of some requirements in IR46 that were erroneously removed for tomato potato psyllid and the import of any carrier host fresh fruit and vegetables with green material when harvested and packed in the field, and not a packhouse;
  • Removal of the Appendices previously held in this Manual which provided listings of prohibited pests, declared pests, and restricted matter. Such lists can now only be found from a single point of truth – the online Tasmanian Biosecurity Compendium.

You can find the Plant Biosecurity Manual Tasmania 2023 edition version 2 on our website and the new version from Friday 29 March 2024.

Biosecurity Advisory 09/2024 - Seasonal Biosecurity Compliance Reports

​Biosecurity Tasmania has commenced publishing seasonal compliance activities undertaken by Authorised Officers, in accordance with several pieces of legislation covering Tasmania's biosecurity system.

The Seasonal Compliance Reporting provides a summary of key compliance actions undertaken by Biosecurity Tasmania based on the Compliance and Enforcement Framework.  There are numerous other compliance activities undertaken including education and support activities to encourage voluntary compliance, responses to complaints and a range of other audits and inspections which are not captured in these reports.

Areas covered by biosecurity legislation include plant biosecurity, animal biosecurity and welfare, invasive species (including cat management) and product integrity (including food safety, agricultural and veterinary chemical use and traceability).

Biosecurity Tasmania applies a graduated and proportionate approach to the application of compliance and enforcement actions, that include:

  • Educational outcomes
  • Cautionary outcomes
  • Application of sanctions such as suspension or cancellation of permits or approvals
  • Biosecurity Detection Notices (BDNs)
  • Prescribed Infringement Notices (PIN)
  • Prosecutions

Several factors are considered when determining the appropriate response ranging from the nature, impact, intent and severity of the allegation to evidence of criminality for more serious offences. This ensures the most proportionate and consistent compliance or enforcement response is taken in any incident.

The recently published Spring 2023 compliance reporting can be viewed on the Biosecurity Tasmania website at​ecurity/seasonal-biosecurity-compliance-report.

The reports will be published quarterly and will be made available on this webpage.​

Biosecurity Advisory 05/24 - Tasmania is fruit fly free, help us keep it that way!

​Spring and summer are the peak seasons for fruit fly activity on mainland Australia, meaning it is also a time of increased risk for Tasmania.  That's why Biosecurity Tasmania is asking all Tasmanians to be on the lookout for anything unusual they may find in fruit.

Biosecurity Tasmania has strict import requirements and ongoing statewide surveillance in place, all aimed at reducing the risk of fruit fly getting into Tasmania.

Tell-tale signs of fruit fly to look out for include live larvae or eggs in the flesh of fruit or small puncture marks on the skin of fruit.  Fruit fly larvae look similar to blowfly maggots and could be found in fruit that you have purchased, or from fruit grown in your backyard.  

Fruit flies lay eggs in a wide range of fruits and fruiting vegetables.

Good biosecurity is a shared responsibility. Biosecurity Tasmania works closely with mainland states to help manage fruit fly risks and over the spring and summer months there are increased inspections of imported fruit fly host produce at the Tasmanian border. However, while the risk to Tasmania can be lowered it can unfortunately never be reduced to zero. This is why it's takes all of us, industry, government and the community, to keep Tasmanian fruit fly free. We all need to remain vigilant and work together to help protect Tasmania.

Anyone who notices any larvae in fruit is asked to put the fruit in a sealed bag or container and place it in the refrigerator and contact Biosecurity Tasmania on 03 6165 3777. Please DO NOT dispose of any fruit that has larvae in it.

Biosecurity Advisory 04/2024 - Upcoming Tree Biosecurity Workshops

​The Tasmanian Department of Natural Resources and Environment Tasmania and Plant Health Australia will be conducting free tree biosecurity workshops in February 2024.

The purpose of the workshops is to raise awareness and enable the early detection of exotic pests that pose significant biosecurity risks to trees in our urban, natural, and commercial environments.

Two workshops will be held in the North and South of the state:

Hobart - 20 February 2024 10.00am-3.00pm

Launceston - 21 February 10.00am-3.00pm

These workshops will be of particular interest to those working in the field with trees, those already undertaking tree health assessments and/or plant pest trapping and treatments, and those who are interested in collecting records and data on tree health in relation to their area of work. The focus will be on biosecurity pests of concern. 

The workshop will cover:

  • The importance of biosecurity
  • Signs and symptoms– what do we mean by dieback, cankers or frass and what do they look like?
  • Information about key pest threats - What do they look like? What should you look for?
  • Introduction to MyPestGuide™ Trees and MyPestGuide™ Reporter App
  • How to report suspect exotic pests

If you would like to participate in the workshop, please RSVP by completing the following form:

RSVPs are due by 9 February 2024.

Biosecurity Advisory- 01/2024- Emergency General Biosecurity Direction for European honey bees and associated products- renewal January 2024

​Due to the current situation of varroa mite (Varroa destructor) in New South Wales (NSW), the Tasmanian Chief Plant Protection Officer has put in place an extension to the general biosecurity direction (emergency), to prevent the introduction of this honey bee parasite into Tasmania.

This direction takes effect as of 12am on Sunday 7 January 2024 and remains in effect for six (6) months, unless it is revoked earlier. The direction prohibits the import into Tasmania of any:
  • European honey bee (Apis mellifera); or
  • any animal product produced by, or from, a European honey bee other than commercially produced bee products such as honey filtered to a maximum 2 mm pore size and melted refined beeswax, or another process approved by the Chief Plant Protection Officer; or
  • any used beekeeping equipment; or
  • any other thing that may reasonably be suspected of being a carrier of bees, or any pest or disease that may affect bees.
This extension has been put in place as NSW transitions their varroa mite response from eradication to management. Once completed, ongoing risk analysis work being conducted at both the national and state levels will inform future imports of bees, bee products and beekeeping equipment into Tasmania. While this general biosecurity direction (emergency) remains in place, producers will need to continue sourcing queen bees from within Tasmania.

A copy of the general biosecurity direction (emergency) is available on this webpage:

Biosecurity Advisory 49/2023 - Biosecurity Basics help protect Tasmania

With the arrival of summer, Biosecurity Tasmania is urging visitors, and all Tasmanians, to be extra vigilant for potential biosecurity risks they may bring with them on the journey to Tasmania and to remember the Biosecurity BasicsCome in Clean, Check your Bags, Stay on the Path, and Report anything Unusual! 

A forgotten piece of fruit in your luggage, mud caked on vehicles and equipment, clothing or footwear and recreational equipment that has not been checked and cleaned, can potentially have a serious impact on Tasmania’s primary industries, environment, and our way of life.

The Biosecurity Basics are simple, yet practical actions we can ALL take to help protect Tasmania from the negative impacts of pests, weeds and diseases. 

Check your Bags is an important Biosecurity Basic action. You may not even realise that you are bringing a biosecurity restricted item into the state when you visit or return home. Take a few extra minutes when preparing to travel to Tasmania to ensure you are not bringing fruit and vegetables, some animal and seafood products as well as plants, soil and seeds. 

Many pests can hitchhike their way into Tasmania inside an item in your luggage. For example, the larvae of the tiny but dangerous fruit fly may be lurking in an uneaten apple. Dispose of these items or declare them on arrival. Your actions can help Tasmania remain fruit fly free.

The same applies to buying items online or receiving gifts from friends and family overseas. Be sure to Check your Parcels if ordering goods online. Also let your family and friends know about what they can and can’t send to you in Tasmania​.

Come in Clean is another simple Biosecurity Basic that can help prevent the introduction and spread of harmful pests and diseases.  Mud on your vehicle, caravan or trailer could contain harmful weed seeds or other pathogens. Just as a single drop of water left inside the waders you used while angling in New Zealand could contain didymo. Also known as “rock snot”, didymo is a freshwater algae found in many rivers and streams in NZ and has caused serious damage to our neighbours’ river ecosystems, fish and the pleasures of fly fishing.

If you have visited rural areas or been around farm animals in Indonesia/Bali, you may have come in contact with soil or other organic matter that could contain the foot-and-mouth disease virus. Cleaning your clothing, footwear and any gear (or even leaving some items behind) before you return to Australia is vital to ensuring that our country remains free from this serious animal disease.  

We all have role to play in helping to keep Tasmania free from the many biosecurity threats that are present in other Australian states and territories, and across the globe. We all have a general biosecurity duty​​ to take the necessary actions to protect Tasmania’s biosecurity – in fact, it’s the law!

Get to know ALL the Biosecurity Basics - visit the webpages today to find out more about how you can help protect Tasmania:
