Fire Breaks & Hazard Reduction


Firebreak installation and hazard reduction is a legal requirement that is outlined within the City of Swan - Fire Hazard Reduction Notice (Firebreak Notice)(PDF, 73KB)which is advertised annually in The West Australian and local newspapers.

Property owners are therefore required to ensure that their properties comply with all requirements within the Annual Firebreak notice from November 1 with standards maintained until April 30 the following year.

Firebreak inspections are carried out throughout this period by City of Swan Fire Control Officers (Community Safety Advocates). Property owners that do not comply with the City of Swan firebreak requirements may be infringed, or hazard reduction work may be carried out by the City of Swan at the property owner’s expense.

Hazard reduction

Reducing the amount of available fuel on a property will assist to protect life, property and the environment. The City’s Resident’s Vegetative Fuel Load Guide(PDF, 9MB) provide practical advice on how to estimate and manage the vegetative fuel loads. Examples of mitigation works includes:

  • Maintain long grass to a height no greater than 10cm
  • Under prune trees by removing branches 2m off the ground. This will minimise the likelihood of ground fires igniting tree crowns 
  • Rake to remove leaf, dead vegetation and understory in forest or wooded areas to create ‘park land’ cleared area within the vicinity of dwellings and assets
  • Controlled burning is an effective way to reduce available ground fuel and understory, however, controlled burning requires considerable experience in order to be carried out safely and conditions apply. For more information contact your local Bushfire Brigade or the City of Swan.


A simple and effective method of protecting your property and community from the effects of fire, firebreaks:

  • Can reduce the spread of fire by providing a no fuel area
  • Can be used to isolate hazards and protect assets, e.g. firebreaks around assets, fuel dumps and hay stacks
  • Allow safe access for fire fighting vehicles
  • Provide a control line to assist brigades during fire fighting, back burn or mop up operations.

Firebreak construction

  • Firebreaks are to be developed and maintained clear of all obstacles and flammable materials to create a minimum of 3 metre wide trafficable surface suitable for four wheel drive vehicles
  • Overhanging branches must be pruned to provide a 4m vertical clearance above the full width of the firebreak surface.
  • Boundary firebreaks must be aligned immediately inside and adjacent to the external property boundaries
  • Firebreaks must be constructed to ensure a continuous trafficable surface around the lot and not create ‘dead ends’ or restrictions
  • Firebreaks may be constructed by ploughing, grading, raking, burning, chemical spraying or any other method that achieves the required standard.
  • Remove all flammable materials from firebreak.
  • Alternative firebreaks that are approved in writing by the City, or as depicted within a Fire Management Plan approved in writing by the City, are to be constructed to the same standard as general firebreaks and must be constructed along the specified alignment.

Please refer to the Fire Hazard Inspection Notice(PDF, 73KB) for basic property owner requirements and the Annual Fire Season Guide(PDF, 467KB) for the full copy of property owner requirements. For additional details, please call the City on 9267 9267.

    Suburban blocks

    If your property is in an urban area and is less than 5,000m², then mowing or slashing may be used as an alternative method. The height of the vegetation should not exceed 5cm over the entire area of the property.

    Rural properties

    if your property is 5,000m² or greater, then by November 1 your property MUST have a minimum of 3m wide firebreaks with a 4m vertical clearance around the inside boundaries of your property. Firebreaks are to clear of all flammable material, free from obstructions and should allow large fire fighting vehicles ease of movement without terminating into dead ends at any point. On rural properties with higher fuels additional work may be requested, this may include the requirement to slash all long dry grass adjacent the boundary firebreak. Properties must be maintained to this standard until April 30 the following year.

    Rural land 100 hectares or more: if your property is in a rural area and greater than 100 hectares in size, in addition to the above requirements for rural properties, additional firebreaks will be required to divide your property into areas not exceeding 100 hectares.

    Verge maintenance in Rural areas

    The City of Swan is committed to keeping residents, facilities and the environment safe from the threat of bushfire. Within the City there are thousands of kilometres of rural verges, a significant verge maintenance program operates to manage unwanted vegetation on these verges.

    Grassed verges that are accessible are mowed on an annual program, additionally the City conducts a significant road tree pruning and verge clearing program to improve the safety for all road users and reduce identified fire hazards.

    The prioritisation of hazard reduction work takes into consideration wellbeing and safety for all road users, the actual fire risk from a verge, not just the visual amenity and considers the valuable environmental habitats which exist, some rural verges contain populations of rare flora and fauna which the City is required to protect.

    The threat from fire to private property can be greatly minimised by maintaining a low fuel area between the verge and property. Landowners are encouraged to consider the verge adjoining their property as a part of their land's overall fuel management plan.

    Removal of non-native vegetation and non-permanent works such as slashing, reducing leaf litter and removing fallen branches are acceptable methods to address the fuel load. Burning of verges, clearing or thinning existing native vegetation is not allowed without appropriate approvals from the Department of Environment and Regulation and the City of Swan. If you wish to discuss the management of a rural verge please call the City of Swan on 9267 9267.

    Semi rural properties

    Maintain grassed areas, as far as reasonably practical to 50mm over the entire area. It is recommended that property owners program their hazard reduction in conjunction with the installation and maintenance of firebreaks. If a property is steep, rocky or too wet, an alternative measure may be required to minimise fire hazards, this will need to be formalised by applying for Alternative Firebreak prior to October 15 as outlined in Alternative Firebreaks.

    Alternative firebreaks

    If it is impractical for you to install firebreaks along all or parts of your internal boundaries, you may request permission from the City to install a firebreak in an alternative location or of a different nature. Your request must be received by October 15 to be considered.

    Please complete the alternative firebreak application form(DOC, 110KB) and submit it to

    Fire Management Plans

    Where a property is affected by an approved bushfire management plan, property owners must still comply with all requirements of the Annual Fire Reduction Notice and with any additional requirements outlined within that plan. Property owners should seek clarification from the City if they are unsure of their responsibilities and requirements outlined within the Fire Management Plan.

    The application of stock

    This is an effective method to reduce grass height especially on properties that are difficult to maintain with machinery but will require appropriate fencing, stock branding and in certain areas planning approval. For additional information regarding planning contact the City of Swan on: 9267 9267 For information regarding animal brand and movement requirements visit the Department of Agriculture and Food website or phone 9368 3333.

    Application of herbicides

    This is an effective means to reduce weeds and grasses if applications are properly planned. Generally herbicides are applied by utilising a polythene knapsack or a machine mounted spray system, this should be carried out 2 – 3 times throughout the year in order to be effective and but will not produce immediate results. First application should occur in autumn to be followed up with subsequent applications to control regrowth and allow dead material to rot away prior to fire season. Care and advice must be taken to ensure herbicide does not cause harm to people, animals or the environment within the area of application. Property owners should not spray verges, any public open space or areas near waterways.

    *If you have any concerns in relation to meeting your firebreak obligations, please contact the City on 9267 9267 and a Community Safety Advocate will be happy to assist you with advice.

    Asset Protection Zones

    Compliance with Asset Protection Zone (APZ) requirements is essential in order to protect buildings in bushfire risk areas and to increase the safety of residents and fire fighters that are involved in defending buildings during a bushfire.


    An APZ is an area that has reduced flammable vegetation and materials which may surround habitable buildings including attached and nearby structures and essential infrastructure. An APZ minimises the likelihood and impact that direct flame contact, radiant heat and ember attack may have on buildings and assets in the event of a bushfire. This area must extend out 20m from the external walls of a building or asset.


    In order to protect buildings in bushfire risk areas and to increase the safety of residents and fire fighters that are involved in defending buildings during a bushfire it is essential that you comply with the APZ requirements. APZ are a legislative requirement within the City of Swan. Please see the City's Fire Hazard Reduction Notice for full details.

    For additional information, please refer to the City's annual fire guide(PDF, 467KB) available at libraries and Place Offices or call City of Swan on 9267 9267.
