Prohibited Matter

​​​​​​​​​​​​​​​​​​​​​​​This page contains known pests and diseases that have been specifically listed as “notifiable”, meaning any new detection of the disease or pest in Tasmania (or a part of Tasmania where the pest or disease is not known to occur) is a reportable “biosecurity event”.

Section 73 of the Biosecurity Act 2019 (the Act) imposes mandatory notification requirements in respect of biosecurity events, which apply to specified classes of persons and require notification of the biosecurity event to an authorised officer as soon as practicable after the person becomes aware of the biosecurity event.​​

​​D​efinition of "prohibited matter"​​

Sectio​n 20 of the Act defines "prohibited matter" as follows: ​

20. Prohibited matter

​​(1) The Minister may, by notice published in the Gazette, declare any biosecurity matter, or class of biosecurity matter, to be prohibited matter if the Minister is satisfied on reasonable grounds that –

(a) the biosecurity matter, or class of biosecurity matter, poses a significant biosecurity risk to Tasmania or a part of Tasmania; and

(b) the declaration is necessary to prevent, eliminate, minimise, control or manage the biosecurity risk posed by the biosecurity matter or class of biosecurity matter.

​(2) The Minister may, by notice published in the Gazette, declare any carrier, or class of carriers, to be prohibited matter if the Minister is satisfied on reasonable grounds that –

(a) the carrier, or class of carriers, poses a significant biosecurity risk to Tasmania or a part of Tasmania; and

(b) the declaration is necessary to prevent, eliminate, minimise, control or manage the biosecurity risk posed by the carrier or class of carriers.

​(3) A declaration under this section may make provision for transitional arrangements –

(a) for the lawful disposal, treatment or destruction of any biosecurity matter, or carrier, that becomes prohibited matter as a result of the declaration; and

(b) that specify certain provisions of this Act ​as not applying in respect of such disposal, treatment or destruction of the biosecurity matter or carrier.

​​Prohibited matter is biosecurity matter or carriers assessed to be of greatest biosecurity concern. A person cannot possess or engage in any form of dealing with prohibited matter without a special permit – a prohibited matter permit. ​
