The Western Australian Organism List (WAOL) has been created to publish the status of organisms that have been categorised under the Biosecurity and Agriculture Management Act 2007 (BAM Act).
Organisms are grouped into four main classifications:
- Declared pests (section 22)
- Permitted (section 11)
- Prohibited (section 12)
- Permitted requiring a permit (73, BAM Regulations 2013).
Under the Biosecurity and Agriculture Management Act 2007 all declared pests are placed in one of three categories, namely C1 (exclusion), C2 (eradication) or C3 (management).
The C1 category (Exclusion) — Pests will be assigned to this category if they are not established in Western Australia and control measures are to be taken, including border checks, in order to prevent them entering and establishing in the State.
The C2 category (Eradication) — Pests will be assigned to this category if they are present in Western Australia in low enough numbers or in sufficiently limited areas that their eradication is still feasible.
The C3 category (Management) — Pests will be assigned to this category if they are established in Western Australia but it is feasible, or desirable, to manage them in order to limit their damage. Control measures can prevent a C3 pest from increasing in population size or density or moving from an area in which it is established into an area which currently is free of that pest.
Organisms that are unlisted are those that have not been declared by the Minister for Agriculture and Food as permitted, prohibited or declared pests, and therefore are not included on the WAOL. Section 15(2) states unlisted organisms cannot be imported, except with a permit. This provision requires therefore that people must seek permission to bring unlisted organisms across the border into Western Australia so that an assessment can be made about any biosecurity threats they may pose to the State.
