NEWP is a vital mechanism for implementing the Australian Weeds Strategy 2017-2027 and achieving action under the National Framework for the Management of Established Pests and Diseases of National Significance.

July 2026
The National Biosecurity Committee (NBC) agreed 14 national established weed priorities, following a prioritisation process under the NEWP initiative that aims to improve weed management in Australia.
In agreeing the new national established weed priorities, governments are not agreeing to any regulatory changes. Regulatory decisions on weed management are the responsibility of individual state and territory governments.
The national established weed priorities represent an opportunity for interested governments, industry and community organisations to work together on improving the management of one or more species on the list. Jurisdictions or government agencies may choose to not collaborate due to no or limited negative impacts occurring or a focus on other priorities in that jurisdiction.
The 14 species below were agreed as national established weed priorities:
Species (common and scientific name)
| African lovegrass (Eragrostis curvula) | Olive (Olea europaea) |
| Amazon frogbit (Limnobium laevigatum) | Ox-eye daisy (Leucanthemum vulgare) |
| Arum lily (Zantedeschia aethiopica) | Sea spurge (Euphorbia paralias) |
| Calotrope (rubber bush) (Calotropis procera) | Siam weed (Chromolaena odorata) |
| Giant rat’s tail grass (GRT) (Sporobolus pyramidalis)* | Spanish heath (Erica lusitanica)* |
| Harrisia (Harrisia martinii)* | Tropical soda apple (Solanum viarum) |
| Neem tree (Azadirachta indica) | Wandering trad (Tradescantia fluminensis) |
*Assessed as lead species for a nominated group of closely-related weeds. Group species are in the NEWP assessment report.
The NEWP assessment report communicates the assessment results from the prioritisation process. The report contains assessment results for each species, including details on where it is found in Australia, the current and potential negative impacts (economic, environmental, social and cultural), beneficial uses and feasible actions to improve management.

NBC agreed to undertake further work before making a decision on Buffel grass as a national established weed priority under the NEWP initiative. This process will be led by an NBC working group who will provide advice back to NBC by December 2026.
Buffel grass presents a unique and complex case that requires further consideration. Buffel grass is of interest to a broad range of stakeholders. It is a highly valued pasture grass for the cattle industry. Conversely, Buffel grass has significant negative impacts, such as in conservation areas, and requires management to reduce these negative impacts.
The NEWP assessment report identified that:
For each of the 14 national established weed priorities, implementation of management actions is dependent on the level of co-investment secured. Hence, a species being agreed as a priority does not guarantee the implementation of management actions.
Governments, industry and community organisations are requested to consider co-investing in the national established weed priorities to enable implementation of proposed management actions with stakeholders. For governments, a decision to participate or invest in NEWP activities will be based on consideration of the benefits derived by that state/territory and its stakeholders, aligned to current policy frameworks and priorities.
When resources are secured to be able to progress the identified feasible actions for a national established weed priority, NBC will finalise and communicate the NEWP delivery stream for each priority.
For implementation, broader engagement will occur with all stakeholders to gain a shared understanding of the negative impacts of a species and to collaborate to refine actions to improve management.
Further information on investment and implementation will be communicated on this page, once available.
It is anticipated that it will take some time for organisations to consider and secure co-investment, to enable implementation to proceed.
The NEWP prioritisation process is described in the Guide to nominating a nationally significant weed.
It involved four steps:
1. Expression of interest – complete
2. Nomination – complete
3. Assessment – complete
4. Review and approval

Some species nominated under the NEWP initiative have benefits, for example, as pasture grasses.
A plant is considered a weed if it is not valued where it is growing and requires some form of action to reduce its negative effects. Thus, a pasture grass providing benefits as feed for livestock is not considered a weed. However, the same plant species in a national park can be considered a weed (not valued) where it outcompetes native plants and requires management.
It is appropriate that species that have benefits and negative effects are eligible for consideration within the process, to assess harmful impacts and consider any actions that could improve management. This is consistent with principles underpinning weed management in Australia described in the Australian Weeds Strategy 2017-2027.
The detailed assessment process considered the benefits of a species, as described in the Guide to nominating a nationally significant weed. This included consideration about possible strategies to minimise negative impacts of a species while retaining its beneficial uses.
In agreeing the national established weed priorities, governments are not agreeing to any regulatory changes. Regulatory decisions on weed management are the responsibility of individual state and territory governments, through their own regulatory frameworks.
The NEWP initiative, including the WoNS label, has no regulatory basis and does not create landholder management obligations.
A weed species must be endorsed as a candidate target for biological control by the EIC through the current procedure before permission is sought to release a biological control agent for that species (EIC 2019). The Protocol for Biological Control Agents (Department of Agriculture, Fisheries and Forestry 2022) provides a national standard for the assessment and introduction of exotic biocontrol agents into Australia under the Biosecurity Act 2015 and the Environment Protection and Biodiversity Conservation Act 1999.
The Australian Pesticides and Veterinary Medicines Authority (AVPMA) evaluates, registers and regulates agricultural and veterinary chemicals in Australia. Before a new agricultural or veterinary chemical product can be legally supplied, sold, or used in Australia it must be registered by the APVMA. Further details here.
The Environment and Invasives Committee’s Weeds Working Group (WWG) commissioned a report in 2020 to analyse the Weeds of National Significance (WoNS) initiative and draft a framework to underpin the future of nationally established weeds management.
The report ‘National Established Weed Priorities – Towards a National Framework’ proposed a draft framework for the nationally coordinated management of established weeds.
Wild Matters Pty Ltd subsequently developed the National Established Weed Priorities (NEWP) Framework and Implementation Plan, with extensive input and feedback from stakeholders, including through an industry and community Advisory Group.
NEWP retains the essence of the original WoNS initiative (through the WoNS component) but also moves beyond the single species approach to encompass other national established weed priorities including Weed Issues of National Significance (WINS) and a National Established Weeds Action List (NEWAL). This broadens the scope of the original initiative, addressing landscape-scale management issues for established weeds (WINS), and offering continued management of discrete national priority actions where required (NEWAL).
EIC endorsed the NEWP Framework and Implementation Plan in June 2023.
On 30 November 2023, the National Biosecurity Committee agreed to a phased approach to progress the NEWP implementation.
This phased approach initially focuses on determination of new national weed priorities.
Following determination of new national weed priorities, government and non-government stakeholders will consider investment. This will determine the scale of NEWP implementation.
Reflecting that NEWP is a collaborative initiative between government and non-government stakeholders, a NEWP Steering Group, consisting of representatives of all stakeholder sectors in weed management, is leading the overall implementation of NEWP.
The NEWP Steering Group provides strategic advice to the EIC WWG, which is accountable for this initiative to the Environment and Invasives Committee and the National Biosecurity Committee.
Further details are contained in the NEWP Terms of Reference.
The NEWP Steering Group has overseen the NEWP prioritisation process.

The NEWP SG met virtually on 8 May 2024 to discuss delivery of the initial phase of NEWP, that will determine new national weed priorities.
Government and non-government members gained a shared understanding of their role as members of the NEWP SG, work to date and scope of work to deliver the initial phase.
The Weeds Working Group Chair provided an overview of the NEWP initiative in terms of goal, drivers, components of NEWP and the initial phase approved by the National Biosecurity Committee.
The group discussed and endorsed the Communications and Engagement Plan and Project Plan.
Draft nomination process documents were shared with members for feedback. Documents have been informed by multiple workshops held with interested groups.
The NEWP SG met virtually on 3 July 2024 to review the draft guide to nominating a nationally significant weed, forms and assessment process.
The NEWP SG and Project team are continuing to work to finalise the process for consideration by the Environment and Invasives Committee, including approval to call for nominations.
The outcome of the nomination and assessment process will determine the weeds recommended for inclusion on the new list of national established weed priorities.
The NEWP SG met virtually on 10 September 2024 to receive an update on the Expression of Interest (EOI) process (before closing on 20 September) and status of key activities on the workplan, including systems and procedures. The preliminary assessment systems and procedures, which apply the criteria in the Guide to nominating a nationally significant weed, were worked through and refined with the NEWP SG.
Botanists from state/territory herbaria have been engaged to provide advice to the NEWP SG on EOI eligibility against criteria and proposed species groupings (i.e. closely-related groups of species).
Communication activities to promote the opening and closing date of the EOI process were summarised and included stakeholder emails, messages through networks and social media posts.
The NEWP SG met virtually on 1 October 2024 to consider the Expression of Interest (EOI)s received, and agreed on eligible EOIs, ineligible EOIs and species groupings.
Representatives from the botanist group attended to provide advice on EOI eligibility and groupings and answer any queries from NEWP SG members to inform their decision-making.
Assessment guidance material (developed for assessors) was endorsed by the NEWP SG. The group discussed the formation of the expert panel to assess current and potential negative impacts of species.
The NEWP SG explored the concept of Weed Issues of National Significance (WINS), and it was agreed to hold a problem-structuring workshop to further develop this.
It was agreed to publish the outcomes of the EOI step on the Weeds Australia website and for organisations to be notified via email, with those who submitted an eligible EOI invited to submit a nomination by 12 January 2025.
The NEWP SG, with the Weeds Working Group (WWG), met in-person and online on 25 February 2025 to consider the preliminary assessment results of all nominated weeds (shortlisting process to reduce the number of nominations proceeding to detailed assessment). The NEWP SG agreed 6 nominations not to proceed to detailed assessment; 29 nominations to proceed to detailed assessment; and lead species for groups proceeding to detailed assessment.
The group discussed the detailed assessment components (National significant impacts, Feasibility of management and Benefits from national coordination) and their timing. Members agreed to promote the opportunity to join the expert panel by distributing the Expert Panel EOI information through their channels.
It was agreed to publish the outcomes of the preliminary assessment process on the Weeds Australia website and to notify organisations via email.
On 26 February 2025, NEWP SG and WWG members participated in an in-person and online problem-structuring workshop on Weed Issues of National Significance (WINS) to refine purpose and key components of a rubric to evaluate what would make a good WINS. The group agreed to continue work with the aim of piloting the WINS concept.
The NEWP SG met virtually on 2 July 2025 to discuss status of the nationally significant weed detailed assessment process and timing to complete components.
The Group also discussed the Weed Issues of National Significance (WINS) concept and next steps to potentially pilot.
The NEWP Project team, assessors and NEWP SG are continuing to work to finalise the assessment process components and report for consideration by the Environment and Invasives Committee and National Biosecurity Committee late this year.
The outcome of the assessment process will determine the weeds recommended for inclusion on the new list of National Established Weed Priorities.
The NEWP SG met face-to-face and virtually on 25 and 26 September 2025 to review and provide advice on the draft assessments for the ‘nationally significant impacts’ and ‘feasibility of management’ components of the NEWP detailed assessments.
The NEWP Project team, assessors and NEWP SG are continuing to work to finalise the assessment process components and report in 2025.
The NEWP SG met virtually on 26 and 27 November 2025 to review and provide advice on the draft assessments for the ‘benefits of national coordination’ component of the NEWP detailed assessments.
The group also discussed Weed Issues of National Significance (WINS) concepts and considered a short-list of WINS for further scoping.
The NEWP Project team, assessors and NEWP SG are continuing to work to finalise the assessment process components and report, with advice to the National Biosecurity Committee regarding new national weed priorities, expected in the first quarter of 2026.
