Biosecurity Advisory 15/2018 - Fruit Fly Update - 4 May 2018

​A major effort is being undertaken to eradicate fruit fly from Tasmania.

Included in this effort has been:
  • Approximately 2500 properties have cooperated with the fruit fly response
  • Spot baiting undertaken at approximately 1200 properties
  • Surveillance through checking of around 1000 permanent traps placed around the state
  • Checking of an additional 333 surveillance traps placed around infected sites
  • Approximately 4500 trap checks undertaken
  • Approximately 3300 larval surveys undertaken
This work would not have been possible without the support of the community and industry which has enabled access to properties for surveillance and eradication activities as well as reported possible signed of fruit fly for follow-up investigation.

Encouragingly, there have been no further detections of fruit fly either within or outside current control areas since the last update.    

On Flinders Island, no detections have been made at either Badger Corner or Trousers Point since January. At Lady Barron no detections have been made since March 21.

Within the northern control area no detections have been made at or near the Spreyton site since March 16.  At George Town no detections have been made since April 2. While at the other infected site, no detections have been made since February 14.

Although no further detections have been made, there is still further work to be undertaken to ensure these areas can be declared fruit fly free again and enable access to markets where restrictions are in place.

Agreement from the Commonwealth and trading partners is required to achieve the fruit fly freedom status. This means that Tasmania needs to maintain identified processes to give certainty to the Australian Government and our trading partners that we have eradicated fruit fly from the State.

While the cooler winter weather is believed to be a barrier to fruit fly establishment in Tasmania, this alone cannot be relied on to achieve eradication so it is necessary to continue with control measures over coming months.  

This means that we will need to maintain the current control areas on Flinders Island and in northern Tasmania for the coming months until agreement is reached with the Commonwealth and trading partners that they can be lifted.

The Government is continuing to work with the Australian Government to identify what measures and requirements continue to be needed and for how long to meet requirements for fruit fly freedom status being recognised.

The Department will continue to keep industry and the community informed of requirements and changes to requirements.

Mowbray update     

This site was not an outbreak but was investigated in line with established protocols for single fly detections. There have been no further fruit fly detections at Mowbray. Earlier this month, a single adult male Queensland fruit fly was detected at a residential property in Mowbray. Approximately 40 fruit fly traps have been established in the surrounding area and all fruit trees and other host plants have been inspected on more than 100 properties in the immediate vicinity.  Inspections consist of examining all fruit on trees for any evidence of infestation, plus taking a quantity of fruit from the tree and any fruit on the ground to be cut into small pieces to determine if any larvae are present. No further fruit flies have been detected. No evidence of larval infestation has been found. The traps will continue to be inspected for a period of nine (9) weeks after the initial detection.

Biosecurity Advisory 14/2018 - Citrus canker - reinstatement of import requirement in Tasmania

​Citrus canker (Xanthomonas citri susbp citri) has recently been detected in the Northern Territory.  Citrus canker is a serious disease of citrus and can have severe impacts on fruit quality and yield. Citrus canker is not harmful to people or animals.

Biosecurity Tasmania has declared citrus canker to be a List A disease under the Plant Quarantine Act 1997 and has re-in​stated the Import Requirement on the import of Citrus plants and plant products (including leaf material and fruit) as well as agricultural equipment and machinery that may have been in contact with the disease.

Find the re-instated​ Import Requirement 31 on the Biosecurity Tasmania website at:​

Citrus canker has been detected in Australia previously and been successfully eradicated.

For more information on citrus canker, signs and symptoms, visit the NSW Department of Primary Industries website at:​​​​​​sect-pests-and-plant-diseases/citrus-canker​

Furher information can also be obtained at the Outbreak website:​esponses-to-outbreaks/citrus-canker​

Biosecurity Advisory 11/2018 - Notice of change Import Requirement 2 - Fruit fly host produce - Disinfestation with Methyl Bromide

​Biosecurity Tasmania wish to advise that existing Import Requirement 2 in relation to fruit fly host product entering Tasmania has been modified to ensure risk produce is fumigated at a higher temperature.
This is being implemented as  a precautionary measure in a bid to further mitigate risk under current unusual Queensland fruit fly pressure.
This requirement along with others related to fruit fly risk mitigation will continue to be reviewed as per routine practice to ensure requirements are appropriate to the risk.
The revised Import Requirement 2 - Fruit Fly Host Produce - Disinfestation with Methyl Bromide is effective as of 2 March 2018

Biosecurity Advisory 1/2018 - Fruit Fly Detection on Flinders Island

​Biosecurity Tasmania has identified the larvae of two fruit fly on a residential property at Lady Barron on Flinders Island. Entomologists have identified the larvae as a species of Bactrocera fruit fly. 

The larvae were discovered on apricot fruit grown in a residential backyard. Biosecurity officers are currently conducting survey work on the property and liaising with the property owners. At this stage, the incursion appears to be an isolated incident. These investigations will look at response planning as well as treatment options for the potentially infected fruit.

Residents in and around Lady Barron will receive information in coming days that will outline Biosecurity Tasmania's response plan, the treatment options and what measures people can take relating to the movement and removal of fruit. ​

The Flinders Island community, together with visitors to the island are urged to be vigilant and to look out for signs of fruit fly and larvae. Fruit fly larvae look like blowfly maggots and are usually easy to see in the flesh of the fruit. People are required by law to report promptly any signs of fruit fly on their property. If you see anything suspicious, immediately call the Biosecurity Operations Centre on 1800 084 881.

Biosecurity Advisory 16/2017 - Public comment invited on proposal to import Sumatran tiger into Tasmania

The Wildlife Management Branch received species profile to facilitate risk assessments for the potential import into Tasmania of;

 Sumatran tiger (Panthera tigris sumatrae)
Public comments are invited by 21 December 2017

The Sumatran tiger (Panthera tigris sumatrae) is one of six sub-species of the Tiger (Panthera tigris), all of which are either endangered or critically endangered.  The Sumatran tiger is listed as critically endangered by the IUCN, and is managed in Australia and New Zealand through the Zoo and Aquarium Association (ZAA) Australasian Species Management Program (ASMP). The ZAA program provides the maximum possible support for the conservation of Sumatran tigers in the wild via:
  • An assurance population against extinction in the wild;
  • A potential source population for demographic and/or genetic supplementation in the event of severe decline in the wild;
  • As a source population for research that may benefit the conservation of wild tigers or improve our understanding of the species;
  • As a source population for training activities that may benefit the management of wild tigers (eg, capture techniques that can be applied to conflict tigers);
  • As a charismatic species for exhibition and education programs to increase awareness of human impacts on wildlife and inspire support of conservation activities and actions; and
  • As ambassadors for fund-raising efforts for in situ conservation projects that benefit wild tigers and their habitats.
Through the ZAA ASMP the Sumatran tiger may only be offered to wildlife parks and zoos within Australia and New Zealand that are full accredited ZAA members.

The Sumatran tiger is the smallest of all Tiger species and behaviorally, are generally solitary animals. 

The species profile provided has been submitted by a third party, which is predominately used to undertake the risk assessment. DPIPWE has accepted and published the information contained in the species profile in good faith but accepts no responsibility for its accuracy, nor does DPIPWE accept any responsibility associated with the publishing of this material including, but not limited to, liability associated with copyright.

Risk Assessment:

A risk assessment has been undertaken by specialist staff from the Department including, policy and wildlife officers, ecologists and veterinary officers from Biosecurity Tasmania. 
The risk assessment considers three main areas of risk:
  1. Public safety
  2. Establishment 
  3. Consequence

The risk to public safety is considered highly dangerous in the event that the species escaped captivity.

The likelihood of establishment is considered extremely low due to an inappropriate climate match.

The consequence of establishment is considered moderate because of the low climate match, and the species is not known to be a pest, would not harm property but could harm livestock.

Taking these factors into consideration, the risk assessment concluded that the risk posed by importing Sumatran tiger into Tasmania is serious. 


Any decision to allow the import of Sumatran tiger into Tasmania would only be considered where:
  • The species is imported by a Wildlife Exhibition Licence holder that has appropriate facilities to securely house the species.
  • The wildlife exhibition facility can clearly demonstrate they have proficient keepers for that particular species.
Standard conditions associated with the import of a serious risk species include, but are not limited to:
  • Import and keeping is only permitted by facilities approved to keep the species under licence.
  • The wildlife facility must meet minimum standards for animal welfare, human safety and security.
  • The animal must not be released, or be allowed to escape from effective control.
  • Animal welfare requirements under the Animal Welfare Act 1993 and any approved Code of Practice or Management Plan must be met.
  • Individuals must be micro-chipped or otherwise identified.
  • The wildlife facility must be available for inspection at any reasonable time.
  • The maximum number of individuals of a species held at the wildlife facility is to be stipulated on the licence, taking into account relevant factors.  Gender may also be stipulated.  
  • Written approval must be sought prior to movement of animals between wildlife facilities and trade of the species under licence.
  • Record keeping and reporting must be provided to DPIPWE as required by DPIPWE. 
  • Collections containing species subject to approval by DPIPWE must accord with the relevant code of practice for keeping that species.

Provided these mitigation measures are in place and continually complied with, the level of risk to Tasmania of holding the Sumatran tiger within a wildlife facility is considered reduced.
