Weeds

The law in New South Wales defines weeds as any introduced plant having an adverse effect on the environment, the economy or the community (S.15. Biosecurity Act 2015). Some weeds are common and widespread across Hornsby Shire, others are just starting to get established. The impact of weeds can range from being a minor nuisance to posing a serious threat to the environment, the economy or the community.

In the past, certain plants were listed as ‘noxious weeds’ under the Noxious Weeds Act 1993. This Act has since been repealed and the term ‘noxious weed’ is no longer used. Under the New South Wales Biosecurity Act 2015, all plants are now assessed for the risk they pose to the environment, community and the economy. Everyone who deals with plants or plant parts (including a landholder allowing them to grow on their land) must prevent, eliminate or minimise their impact, as far as is reasonably practicable. This is termed a persons’ General Biosecurity Duty and must be discharged (S.22 Biosecurity Act 2015).

State Regulated Plants & Regional Priority Weeds

Plants posing an extreme biosecurity risk to New South Wales are regulated under the Biosecurity Act 2015. These State Regulated Plants are either declared prohibited matter (Part 4), placed under an emergency order (Part 5), a control order (Part 6), within a biosecurity zone (Part 7), or have mandatory measures specified that must be followed (S.24). It is illegal to contravene these regulations and serious penalties apply.

Some plants pose a biosecurity risk to the Greater Sydney region. These Regional Priority Weeds have recommended measures that are considered reasonably practicable to discharge a person’s General Biosecurity Duty (see Appendix 1.2 of the Greater Sydney Regional Strategic Weed Management Plan 2017 - 2022). Although it not illegal for a person contravene these recommended measures, it is illegal for a person to fail to discharge their General Biosecurity Duty and serious penalties apply.

A list of all State Regulated Plants and Regional Priority Weeds and their regulations and recommended measures relevant to Hornsby Shire can be found in the 'Legal Requirements and Recommended Measures' section below. Council officers routinely inspect both public and private land for both State Regulated Plants and Regional Priority Weeds, including high risk businesses such as nurseries, florists and aquariums.

Common, widespread weeds

For common, widespread weeds, every landholder has a General Biosecurity Duty to prevent, eliminate or minimise, as far as is reasonably practicable, the impact the weeds are having (or could have) on the environment, community and the economy (S.22 Biosecurity Act 2015). Council can only enforce the General Biosecurity Duty, however, if all the following criteria are met:

  1. There is clear evidence that the plants are having a significant and direct impact upon the economy, the community, or the environment;
  2. The impact of these plants is exceptional to this situation and not also occurring everywhere else in the neighbourhood;
  3. In proportion to the level of impact the plants are having, it is reasonable and practicable for the landholder to address the impacts;
  4. The landholder is aware of their duty and they refuse to voluntarily prevent, eliminate or minimise the impacts.

If you suspect weeds on your property may be State Regulated Plants or notifiable Regional Priory Weeds (see the section above 'Weeds and the law'), please contact Council as soon as possible on 9847 6666. For these plants, you must follow the regulations, and should follow the recommended measures. A list of all State Regulated Plants and Regional Priority Weeds and their regulations and recommended measures relevant to Hornsby Shire can be found in the 'Legal Requirements and Recommended Measures' section below.

For common, widespread weeds, every landholder has a General Biosecurity Duty to prevent, eliminate or minimise, as far as is reasonably practicable, the impact the weeds are having (or could have) on the environment, community and the economy (S.22 Biosecurity Act 2015). Plants on your land may be impacting the health of you and your neighbours, spreading into local bushland, or adversely affecting the value of your property.

Although Council cannot control your weeds for you, we are more than willing to help you identify the weeds and provide advice on how to best control them. Please contact Council through the Online Services Portal or phone 02 9847 6666.

Information on weed identification and control techniques can also be found at:

If you intend to use herbicides to control weeds, you must always read the label and any permit before using the product, and strictly comply with the directions on the label and the conditions of any permit. To view permits and product labels go to the Australian Pesticides and Veterinary Medicines Authority website. For more information on using herbicides, visit the Department of Primary Industries website.

If you are unable to control weeds on your property yourself, try one of these options:

  • The Australian Association of Bush Regenerators (AABR) website has a list of professional bush regenerators who may be able to undertake the work at a competitive rate.
  • Check local newspapers or search online for garden maintenance businesses.
  • For frail and older people, carers, and people with mobility challenges, Easy Care Gardening provides a subsidised gardening service within the Hornsby area by teams of willing volunteers. Contact them on 9983 1644.

If you suspect the weeds on your neighbours’ property may be State Regulated Plants or notifiable Regional Priory Weeds (see the section Weeds and the law above), please contact Council as soon as possible on 9847 6666. A list of all State Regulated Plants and Regional Priority Weeds relevant to Hornsby Shire can be found in the 'Legal Requirements and Recommended Measures' below.

For common, widespread weeds, every landholder has a General Biosecurity Duty to prevent, eliminate or minimise, as far as is reasonably practicable, the impact the weeds are having (or could have) on the environment, community and the economy (S.22 Biosecurity Act 2015). It is always better to discuss the matter with your neighbour first before approaching Council. Council can only enforce the General Biosecurity Duty if all the following criteria are met:

  1. You provide clear evidence that the plants are having a significant and direct impact upon the economy, the community, or the environment;
  2. The impact of these plants is exceptional to this situation and are not also occurring everywhere else in the neighbourhood, including on your land;
  3. In proportion to the level of impact the plants are having, it is reasonable and practicable for your neighbour to address the impacts;
  4. You have discussed the matter with your neighbour and they refuse to voluntarily prevent, eliminate or minimise the impacts.

If these criteria cannot be meet and you still wish to act, we recommend the following procedure:

  1. If possible, discuss the matter with your neighbour. They may not have realised their vegetation is causing a problem, and this may help maintain good neighbourly relations. Try to reach an agreement with them about what should be done. Refer them to the links listed in the section Weeds on my property.
  2. Give your neighbour the opportunity to rectify the problem before taking further action.
  3. Notify your neighbour in writing of the damage or nuisance being caused by the vegetation. Refer them to the links listed in the section Weeds on my property.
  4. If no agreement can be reached, contact the Community Justice Centres (CJC) on 1800 990 777. The CJC is a free, government-funded service designed to help resolve disputes. Professionally trained mediators provide a safe, independent forum to sit down with the parties and attempt to resolve matters quickly.

If mediation fails and the matter involves trees, hedges, bamboo or vines that might cause damage or injury then the NSW Land and Environment Court has the power to settle such disputes under the Trees (Disputes Between Neighbours) Act 2006. Lodging an application does not require legal representation and the fee is minimal. The applicant completes the form and pays the fee, attaching any supporting documentation (including correspondence that demonstrates to the Court your attempts to resolve your concerns with your neighbour). When the Court receives the application, the Court Commissioner will inspect the property and make a judgement.

Council spends a lot of time, money and effort managing weeds across the Shire. The job is limitless, so we target our resources to achieve the most sustainable outcomes.

If you suspect the weeds on Council land may be State Regulated Plants or notifiable Regional Priory Weeds (see the section Weeds and the law), please contact Council as soon as possible on 9847 6666. A list of all State Regulated Plants and Regional Priority Weeds relevant to Hornsby Shire can be found in the 'Legal Requirements and Recommended Measures' below.

For information on how Council is managing weeds in bushland reserves across the Shire, visit Bushland Management.

If you would like to help control weeds in Council bushland reserves, visit Bushcare.

If you have concerns about weeds on roadsides, nature strips, sport fields, parks, and Council-managed gardens, contact Council through the Online Services Portal or phone 02 9847 6666. Please note that Council may not be able to action every weed concern. Prioritisation will be given to situations where weeds are posing a safety risk, are impacting upon traffic and pedestrians, or are affecting the proper functioning of an asset.

Much public land in Hornsby Shire (such as National Parks, Crown Land and railway corridors) is owned or managed by other land authorities, and Council has no say on how they manage their common weeds.

If you suspect the weeds on Non-Council public land may be State Regulated Plants or notifiable Regional Priory Weeds (see the section Weeds and the law), please contact Council as soon as possible on 9847 6666. A list of all State Regulated Plants and Regional Priority Weeds relevant to Hornsby Shire can be found in the 'Legal Requirements and Recommended Measures' section below.
