Trees within Mosman are protected under Clause 5.9 of the Mosman Local Environmental Plan 2012 and managed under the Urban Forest Management Policy. A property owner is responsible for trees, and vegetation, growing from within the boundaries of their property. This includes branches, and roots, which overhang or grow into adjoining properties.
All pruning work on private and public land requires Council consent unless work is undertaken on an exempt species as listed in Clause 5.9 of the Mosman Local Environmental Plan 2012 as shown within the Urban Forest Management Policy. You can also see Preservation of Trees or Vegetation which includes exempt species below.
Effective 12 August 2015, the 10/50 Clearing Entitlement Scheme has been significantly amended. The entitlement area for the Mosman Local Government Area has been reduced from the original 56% of residential lots affected to 6% of residential lots now affected.
It is the property owner’s responsibility to ensure all works under this scheme comply with the recent changes. Some of the notable changes (but not limited to) include:
- Exclusion of all parcels of land (lots) that are wholly or partly within 100 metres of the NSW coastline map and mapped estuaries, as provided by Land and Property Information from the operation of the 10/50 scheme
- Clarification that landowners will not be exempt from civil liability as a result of negligence or damage occurring during landslip and soil erosion as a result of their clearing
- Category 2 vegetation as listed on Bushfire Prone Maps is excluded from the operation of the scheme
- Non-combustible exempt developments such as decks, suspended slabs and pools which have been constructed according to the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 are excluded from the definition of ‘external wall’
- That section 100R of the Rural Fires Act 1997 is to be amended to include a provision requiring landowners to obtain the written consent of all neighbours for which they are using the distance from those neighbour’s building to clear vegetation on their own property
Given the significant reduction of the areas covered under the scheme, Council urges any property owner wishing to use this scheme to remove trees to check if their property is still covered.
The following information is provided to assist the community:
- Residents should visit the NSW Rural Fire Service website to self assess whether their property is within a clearing entitlement area and works are in accordance with the RFS code of practice .
- Regarding trees on public land – Land owner’s consent is required, there is no obligation for council to allow removal or pruning of trees or vegetation. Residents are not permitted to remove vegetation or trees on Council land.
- Any works required to be carried out on public owned trees, where access is required from public land, prior written approval from Council must be obtained through a Tree Permit Application. Application for Tree Permit for Public Land
- Pruning of public trees from private property – Council strongly recommends that a tree permit assessment is obtained from Council to ensure works conform to the RFS code of practice and Australian Standards. This will also ensure that trees maintain their structural integrity and limit future management issues. Any works carried out not in accordance with AS 4373 are in breach of the RFS Code of Practice as well as Council’s tree preservation. All breaches will be investigated by Council and may result in prosecution and penalties imposed under relevant legislation. Application for Tree Permit Private Property
- Property owners are under no obligation to remove or prune trees on their private land.
- Residents concerned about the negative effects of the legislation should make a submission to NSW Rural Fire Service at NSW Rural Fire Service (RFS) attention the RFS Commissioner.
If a resident has a genuine fire concern the process is to send correspondence in writing to Council or RFS. The RFS will inspect the fire complaint and provide feedback to both the resident and Council.
Enquiries regarding this scheme should be directed to the Rural Fire Service on (02) 8741 5555.
Applying to Carry Out Tree Work
Application forms for tree work, on either private or public land must be completed and paid for online. Application forms can be accessed via the link below .
It is the applicants’ responsibility to provide sufficient information to support the reasons for the requested tree work, particularly for tree removals. Failure to do so may result in consent for the requested works being denied.
Only the owner of a tree or their authorised agents can apply to remove a tree. Applications for trees that are growing on common land (e.g. Strata Plan) must be accompanied by either a letter from the managing agents or minutes of the relevant Strata Plan meeting indicating the majority of owners support the application.
Pruning Overhanging Branches from a Neighbour’s Tree
Council does not have the power to compel a property owner to prune or remove a tree (unless under exceptional circumstances) which is, or is perceived to be, impacting on another property (excluding Council land).
Any person who is affected by overhang from a tree growing from within an adjoining property, including Council land, may apply to prune the overhanging branches. All pruning, if approved by Council, must be undertaken to Australian Standards (AS4373-2007).
If access is required into the adjoining property to undertake the work correctly the property owner must provide the applicant with approval to access the property for works to be carried out. If the pruning does not require access to the tree owner’s property the owner of the tree is not required to give their approval for works to be carried out. In such cases, if Council consent is granted for the works, the consent does not give authorisation to the applicant, or engaged contractor, to enter the tree owner’s property.
In some circumstances Council may insist that the applicant consult with, or inform, the tree owner of the intention to prune their tree prior to Council consent being granted.
Pruning or Removing of Trees Contained Within a Neighbouring Property
If a person wishes to prune a tree contained entirely within a property which they do not own, they will be required to have that property owners written consent for works to be carried out before it can be assessed by Council.
Disputes between neighbours regarding trees are civil matters. Council has no role to play in solving such disputes. If a tree dispute cannot be resolved amicably residents may wish to contact the Community Justice Centre on 1800 990 777 or visit their website at www.cjc.justice.nsw.gov.au.
Trees Protected Within a Development
Council will not accept a tree permit application to remove a tree which is protected under a Development Consent. In such cases a Modification Application must be submitted to amend the Development Consent.
If pruning of a tree is required on a development site a tree permit application must be submitted outlining the pruning work required.
Trees Located on Council Land
All vegetation on Public Land is protected under the Local Government Act and Environmental Planning and Assessment Act. Council permission is required to undertake any work on Public Land. Any person or organisation can apply to undertake work on Council trees and the application will be assessed as outlined below.
Assessment of a Tree Permit Application
Council’s Tree Management Officer will assess the application and provide the determination to the applicant. This process usually takes up to 10 working days. The assessment and determination is based on a visual inspection of the subject tree and consideration of the documentation provided with the application. Council does not provide a tree consultation service and the assessment is not a tree hazard assessment.
What will Council consider when assessing a tree permit application?
The assessment and determination of the application will address, but not be restricted to, the following;
- The health and or condition of the tree or trees; including useful life expectancy and previous pruning record;
- Amenity value of the tree including visual amenity, ecological value, heritage significance, and the tree’s value as habitat;
- Severity and relevance of problem reported;
- The number of healthy trees that a parcel of land can support;
- The impact that the proposed work, whether pruning or removal, will have of the tree or the landscape as a whole.
There are a number of other factors that do not usually warrant pruning or removing trees. These include:
- A tree is shedding leaves, fruit, bark, cones or twigs, particularly where fouling gutters and pools.
- A tree is causing minor shading.
- Unsupported fears about healthy trees/ branches failing
- A tree is causing minor structural damage, such as to footpaths or driveways.
- A tree is causing blockage to pipes, unless the damage is serious and recurring.
Generally Council will not permit the removal of trees to improve views.
What happens following assessment of a tree permit application?
Once an application has been assessed, the determination will be provided to the applicant. Any work is to be undertaken in accordance with the determination detailed on the assessment. Council will not contribute to the cost of any approved tree works.
For approved tree work on public land the applicant must engage one of Council’s approved contractors to undertake the works. The work and payment are to be organised directly with the contractors.
It should be noted that tree work can be a dangerous task requiring extensive training and specialised equipment. Indiscriminate lopping or pruning can also reduce the long-term safety and health of a tree. For these reasons it is recommended that a professional tree worker or arborist, who is adequately qualified and insured, be engaged to undertake the work.
Unless otherwise indicated on the assessment all pruning must conform to Australian Standards (AS4373-2007 Pruning of Amenity Trees).
Appealing a Tree Permit Assessment
If you are not satisfied with the assessment you may formally appeal the assessment by filling out an Application to Appeal Tree Permit Assessment , accompanied by an independent arborist’s report. The matter will be reported to Council for a final determination. A fee is required as per Council’s pricing policy.
Planting Replacement Trees
It is Council policy that a replacement tree be planted to replace any tree removed. Exceptions to this may be made at the discretion of Council’s Tree Management Officer and will be noted on the assessment. Specifications for the replacement will be shown on the assessment form.
At the Council meeting on 15 August 2006 Council formalised it’s position to discourage the planting of Leightons Green Cypress, Cupressocyparis leylandii. At times these trees have been planted to the detriment of neighbours’ views and solar access. The Leightons Green Cypress is a particular problem as it is readily available in advanced sizes, it is fast growing and has a dense habit.
Since formalising its position in regard to Cypress Leighton Green, Council has:
- Continued to eliminate the species from landscape plans through the development application process.
- Made the tree exempt from Council’s tree permit application process.
- Forwarded information to property owners outlining the detrimental effects Cypress Leightons Green can have on neighbours.
- Advertised Council’s position regarding the species in the Council Column in the Mosman Daily.
Council requests property owners consider their neighbours’ solar access and views in planting trees on private property and keep hedges of Cypress Leighton’s Green pruned to a suitable height.

Unauthorised Tree Work
Any person who carries out tree work without Council’s consent may be liable to substantial fines and/or conviction in a court of law. A person may also be liable for a penalty for engaging or allowing another person to remove or prune a tree without Council’s consent.
Reporting unauthorised tree work
If unauthorised tree work is suspected the details of the incident should be noted and reported immediately to Council on 9978 4000.
Put simply this Act provides property owners a legal avenue to have tree issues they believe are unreasonably affecting them or their property considered by the Land and Environment Court. Information on the Land and Environment Court website states:
The purposes of the Act are to enable the Court to make orders to remedy, restrain or prevent damage to property or to prevent injury to any person when a tree that is situated on adjoining land might cause that damage or injury. The Act also permits the Court to order compensation for or rectification of damage caused by a tree.
The Act does not allow the Court to make orders solely for other purposes (such as lopping or removing trees which block views).
However, the Attorney General has recently undertaken a review and made a number of recommendations which will modify the act. Information on the NSW Government Lawlink website states that under the new laws to commence on August 2, 2010, the Act will:
- empower the Land and Environment Court to hear disputes about high hedges that severely block sunlight to a window of a dwelling on adjoining land, or views from such a dwelling;
- support the enforcement of court orders by allowing councils to recover the cost of trimming or removing any trees plus a prescribed administration fee;
- give the subsequent owner of the property the right to enforce certain orders made under the Act;
- give the court authority to hear disputes over trees that have caused damage but have since been removed;
- allow the court to make orders in relation to problem trees and damaged dividing fences;
- enable the court to hear tree disputes on land zoned ‘rural-residential’ but only where a tree is causing damage or risking injury;
- include vines as a prescribed plant under the Act.
Before The Court will hear a case it must first be satisfied that the applicant has made a reasonable effort to resolve the matter with the owner of the land on which the hedge is situated. Where resolutions prove difficult, residents can now apply to have the court intervene without the requirement for a lawyer. The Court will have the power to intervene in cases where a hedge has severely impacted a neighbour’s views or access to sunlight.
The legislation will empower the Court to determine the appropriate height at which a hedge should be maintained through making a balanced judgment regarding the right to privacy versus the broader benefits of maintaining healthy urban vegetation.
Should the land owner upon which the hedge is located choose to ignore the Court’s order, councils will be given the power of enforcement and be able to charge the cost of enforcement and a prescribed administration fee to the resident.
Cases which have been determined by the Court in the past have been based on expert advice and resident submissions and all involve site inspections. The Court also uses Acting Commissioners with arboricultural or related expertise. A review of cases displayed on the Land and Environment Court website shows the Court is taking a balanced and considered approach to matters which it addresses.
The community of Mosman values its trees and Urban Forest assets. Council protects and manages trees on public and private property in Mosman through its Urban Forest Policy and Local Environmental Plan. While Council is happy to provide information to residents on tree management in Mosman it will not become involved in disputes between neighbours. Council will provide assessments on trees where a permit application has been submitted for pruning or removal. Assessments do not provide comment on whether a tree is a hazard to persons or property.
Council will provide the following information to the Court for its consideration in matters involving trees on private land in Mosman. (Note the following documents are available on Council’s website or under Council’s open file policy).
- A copy of Council’s Urban Forest Policy.
- A copy of the relevant parts of Council’s LEP and DCPs.
- Advice on whether the subject trees are covered by Council’s LEP and DCPs.
- Advice on whether the subject trees are included in Council’s Urban Forest Management Register.
- Any valid tree permit applications or assessment documents on the subject trees. (Tree permit assessments are valid for 12 months).
Clause 5.9 of the Local Environmental Plan 2012 is used to manage the pruning and removal of trees on both Council and private land.
Clause 5.9 of the LEP applies to the following:
- All trees which:
- are 5m or more in height; or
- have a circumference of 450mm or more measured 300mm above ground level; or

- are 2m or more in height, only if located in a heritage conservation area, or if are a heritage item or form part of a heritage item.
- Tree ferns (Cyathea australis & Cyathea cooperi) which are 2m or more in height.
Clause 5.9 of the LEP does not apply to the following:

- Umbrella Tree, Schefflera actinophylla
- Wild Olive, Olea europaea subsp. cuspidata
- Willow, Salix spp.
- Trees or other vegetation or matters identified in clause 5.9 of the LEP to which the clause does not apply.
- Further to clause 5.9(6) of the LEP, for Council to be satisfied that a tree or other vegetation is a risk to human life or property, there must be visual and written evidence recorded by a qualified professional arborist which determines an immediate risk and justifies the action taken.
- Further to clause 5.9(8)(e) of the LEP, the clause does not apply to or in respect of weeds declared noxious in the control area of Mosman Municipal Council under the Noxious Weeds Act 1993 .
- Dead wood in trees on private land.
- The maintenance of trees and/or vegetation on roads and public land, if such action is considered appropriate by Council and is undertaken by Council or persons approved and authorised by it to perform any of the actions listed in clause 5.9 of the LEP.
- A tree is harbouring fruit fly as confirmed and recorded in writing by a suitably qualified professional.
Note that all vegetation on Council (public) Land is protected and any work will require the lodgement of a tree permit.
Due to the large number of trees in Mosman most residents live in close proximity to a street or park tree and unfortunately associated conflicts can arise. Council has therefore decided to develop and implement uniformed practices to address problems of impacts from Council trees.
Damage to sewer and stormwater pipes in particular is a difficult and time consuming issue. To assist residents and Council the following information has been prepared to enable all parties to resolve such issues in an efficient and consistent manner.
Trees are an important part of the character of Mosman and the community values the amenity trees provide. Council understands that trees can sometimes affect privately and publicly owned assets near them. The following information is provided to clarify Council’s position and provides advice on the course of action residents should take when there is a concern that private property has been damaged by a tree growing on public land.
Who is responsible for private in-ground services?
A property owner is responsible for the upkeep and maintenance of in-ground services, such as sewer and storm water pipes, even though they may run through or adjoin private and public land. That is a resident is responsible for pipes servicing their property, not only within their property boundary but also, for example; to the sewer main.
How do trees affect in ground services?
Tree roots can enter in ground services causing the pipes to be blocked. While it is possible for a tree root to crack a pipe this is uncommon if the pipe has been installed and maintained correctly. Tree roots often enter a pipe as a result of the pipe failing, usually through deteriorated seals in older pipes.
Why do tree roots enter in ground services?
Tree roots are opportunistic and grow towards wherever conditions are favorable. They do not actively search for water. Tree roots will follow a pattern of growth where, when they come in to contact with water/nutrients, they will grow towards an increasing concentration of water/nutrients. Tree roots will only usually enter pipes that have a fault and are leaking water.
Why might my in ground services be leaking?
Sewer or storm-water services may crack for a number of reasons including the age of the pipe (old terracotta), failure at a joint, ground movement, etc.
What process should I follow if it is alleged the damage or blockage is caused by a tree growing on Council land and I wish to make a formal claim for the cost of repairs?
- You should obtain 3 written quotations for the necessary repair works.
- If excavation through a council road or footpath is required, you will need to obtain a road opening permit which is available from Council.
- Necessary repair work can be undertaken to avoid any further damage and/or reduce the hazard. Note that at this stage Council has not accepted any liability for damages and the decision to undertake repairs is made by the owner of the asset.
- During the course of the works you must arrange for a council officer to inspect the exposed pipe and confirm if Council tree roots have caused the problem or whether the pipe has been damaged for some other reason.
- While on site the council officer will take photos as a record to be referred to later if necessary.
- It is recommended that you also keep your own records.
- If you would like to take further action it will be necessary to make a formal claim against Council for the cost of repairs if you are of the opinion that Council has been negligent in some way. All information gathered above should be included in your claim.
What happens if it appears that the roots are the cause of the problem?
The matter will be referred to Council’s insurers for assessment of liability including the cost for the repairs. For Council to be considered liable for any damages the asset owner will need to provide evidence of negligence of Council and how any such negligence resulted in the damage.
Why does Council take this approach?
It is important to follow the process above as the works relate to a private asset and may involve spending public funds on the repair. The above process needs to be followed for both insurance and governance purposes. This information is provided to advise of the importance of having clear evidence to forward to insurers if there is a claim in the future, particularly if there is a chance the initial damage may have been the result of other causes. The clearer the evidence provided the greater the likelihood of a positive result through any insurance claim.
How can I manage my in ground services so that I can prevent this happening in the future?
The most efficient way to prevent root damage to your services is to replace the old terracotta pipes with new PVC or UPVC ones and use pressure seals. Other methods include the type and compaction of the backfill around these services which help prevent root growth in these areas. Also using chemical or mechanical forms of plumbing equipment to control root development in the pipes, but this may only be a short term solution and might not prevent root ingress in the future.
The pruning of trees to provide adequate clearances for power lines is carried out by Ausgrid contractors. For further information or enquiries please contact 1300 738 733.
