What are Bushfire-Prone Areas?
Across Australia — particularly where urban development meets bushland — there are lands officially designated as likely to be affected by bushfires. These zones, known as bushfire-prone areas (or bush-fire prone land), are not just a theoretical risk: they trigger specific planning and construction requirements for homes, renovations, and new developments.
In New South Wales (NSW), local councils prepare maps of bushfire-prone land for their areas. These maps are then certified by the NSW RFS Commissioner under the requirements of the Environmental Planning and Assessment Act 1979.
Properties within these mapped areas may be subject to additional safety requirements — such as construction to specific fire-resistant standards — to increase protection against bushfire attack.
How to Check If Your Property Is Bushfire-Prone
If you’re concerned whether your land is designated as bushfire-prone, there are a few straightforward ways to check:
-
Use the NSW RFS online mapping tool, which lets you search your address to see if it's within a designated bushfire-prone area.
-
Review a Section 10.7 Planning Certificate issued by your local council, which should note whether the land is bushfire-prone.
-
Consult your local council’s interactive map or PDF bushfire-prone land map. Many councils publish their own maps and spatial viewers for residents to check.
It’s worth noting that mapping is periodically reviewed and certified — so what may have been “not bushfire-prone” a few years ago could change over time.
Importantly: even if your land is not mapped as bushfire-prone, it doesn’t guarantee it’s risk-free. Bushfires can still occur from nearby vegetation, embers transported by wind, or other factors.
What Happens If Your Site Is Bushfire-Prone?
Bushfire Attack Level (BAL) Assessment
If your property falls within a mapped bushfire-prone area and you intend to build, renovate, or undertake “complying development,” you will need a Bushfire Attack Level (BAL) assessment.
The BAL is a measurement of the potential severity of bushfire attack on a building — considering factors such as ember attack, radiant heat, and possible flame contact.
Under AS 3959:2018, there are six BAL levels:
-
BAL-LOW (essentially no additional bushfire construction requirements)
-
BAL 12.5 — ember attack risk
-
BAL 19 — ember attack and increasing radiant heat
-
BAL 29 — significant ember & radiant heat risk
-
BAL 40 — high radiant heat, increased ember attack and possible flame contact
-
BAL FZ (Flame Zone) — highest risk; direct exposure to flame, embers, and heat flux
Which BAL applies to your property depends on:
-
The type of vegetation around the site (fuel type), whether bush or woodland.
-
The distance between the vegetation and the proposed building.
-
The slope of the land below the vegetation (steeper slopes can increase fire risk).
Because BAL depends on site-specific conditions, the BAL rating is not included on the maps themselves — it must be assessed separately.
Building and Development Requirements
If your property is on bushfire-prone land, then any new construction or major renovation must comply with:
-
The relevant guidelines in Planning for Bush Fire Protection 2019 (PBP)
-
The construction standards defined in AS 3959:2018 (or the latest version) — which specify materials, design, glazing requirements, ember resistance, and other elements depending on your BAL.
These requirements are not meant to prevent development altogether — but to ensure that buildings are constructed in a way that reduces risk to occupants and property.
For example: windows, roofs, guttering, external walls, and eaves may need ember-resistant or non-combustible materials; ember guards and ember-resistant gutter systems can be required to prevent ignition from flying embers.
Why Vegetation, Climate, and Urban-Bushland Interface Matter
Several key factors influence bushfire risk and whether an area is designated as bushfire prone:
-
Vegetation type and fuel load: Forests, woodlands, heathlands, or densely vegetated bushland pose higher risk because they can support intense fires. These are typically mapped as “Vegetation Category 1” or similar on BFPL maps.
-
Proximity to urban development (urban-bushland interface): As suburbs expand near bushland, the boundary between bush and built environment becomes more critical — these zones often show up as bushfire-prone.
-
Buffer zones: Maps not only classify vegetation, but include buffer areas around hazardous vegetation to account for possible ember or flame spread.
-
Impact of climate change: With hotter, drier conditions and increased frequency of extreme fire weather, areas once deemed lower risk may become more vulnerable — underscoring the importance of current mapping and adopting protective building practices.
Given these factors, many councils review and update their bushfire-prone land maps regularly (every five years or as needed).
What a Bushfire-Prone Designation Means for Homeowners
If your land is designated as bushfire-prone (or you suspect it might be), you should take several considerations seriously:
-
Check before buying or building — Always use the NSW RFS tool or council maps to confirm bushfire-prone status before purchasing or planning building works.
-
Obtain a BAL assessment — For any new dwelling or major renovation, a qualified bush fire consultant or your council must assess and issue a BAL Risk Assessment
-
Comply with AS 3959 and PBP standards — Use appropriate building materials (non-combustible where required), ember-resistant features, ember-guard mesh, and consider fire-safe design aspects (setbacks, ember guard guttering, roof-metal vs combustible, etc.).
-
Consider ember protection for gutters and eaves — As highlighted on the Gutter Guard Direct blog, ember guards (fine-mesh metal gutter protection) are a critical safety measure in bushfire-prone zones
-
Have a bushfire survival plan and maintain your property — Even with construction compliance, factors like nearby vegetation, windborne embers, and maintenance (e.g., clearing gutters and leaves) remain critical. The NSW RFS recommends every household have an up-to-date bushfire survival plan
The Role of Ember Guards and Gutter Protection
At Gutter Guard Direct, we know that compliance with building standards is just one part of bushfire safety — maintaining protective features like ember guards is equally important. Ember guards are designed to prevent embers from entering roof cavities, gutters and eaves — common entry points for fire during a bushfire.
Our ember guard mesh (2 mm aperture aluminium mesh, CSIRO-tested) is specifically suited to homes in bushfire-prone areas, allowing water flow while blocking fine embers — helping make your gutter system part of your home’s bushfire resilience.
Using non-combustible materials, maintaining clean gutters and reducing fuel near your home complements the regulatory requirements (BAL, AS 3959) and provides practical, day-to-day protection that supports long-term resilience.
Why Bushfire-Prone Planning Matters — Especially Now
With changing climate patterns, prolonged droughts, and more frequent extreme fire weather events, the bushfire risk for many regions is increasing. Areas that once might have been considered safe are now at greater risk — and official mapping, bushfire planning, and building standards must evolve accordingly.
For homeowners, this means it’s more important than ever to check current bushfire-prone maps, assess their individual risk (through BAL assessments), and ensure their homes are built or retrofitted to resist ember attack, radiant heat, and flame contact.
Planning for bushfire-prone land isn’t about preventing you from living in a beautiful, bush-adjacent area — it’s about making that living safer, with informed design, appropriate materials, and sensible fire-aware preparation.
Practical Steps: What You Can Do Today
-
Visit the NSW RFS online mapping tool and check if your property is designated as bushfire-prone.
-
If planning building works or purchasing land, request a Section 10.7 Planning Certificate from your local council.
-
If your property is in a bushfire-prone zone, engage a qualified bush fire consultant and obtain a BAL assessment.
-
Ensure your building design and materials comply with AS 3959:2018 and PBP requirements.
-
