Accredited Bushfire Attack Level Assessments in Australia
Bushfire Prone Planning provides accurate, site-specific bushfire attack level assessments for properties in bushfire-prone areas. Our accredited bushfire consultants have decades of practical field experience and extensive fire behaviour knowledge to anticipate potential challenges early and provide solutions that keep your project moving. Our BPAD level 1, 2 and 3 practitioners work closely with you – from initial site inspection through to project approvals – to ensure the entire process is clear, accurate, and aligned with your goals and/or deadlines.
We deliver comprehensive BAL assessments for single dwellings, multi-lot subdivisions, commercial developments and industrial projects, clearly outlining the relevant construction requirements under the Australian Standard (AS 3959-2018) and what they mean for your project. We also provide support with requirements for building permits, BAL certificates, or other documentation requested by your local council or approval authority.
Where necessary, our consultants identify practical design and site planning considerations in the early stages to manage bushfire risk and compliance, reduce unnecessary construction costs, and ensure long-term bushfire resilience. By understanding site constraints and BAL requirements early, you can make informed decisions, prepare local council documentation, and progress your development application or building permit more efficiently.
BAL assessments differ between applications, particularly where there are different occupancy, access, construction, or bushfire safety considerations. Bushfire Prone Planning is fully qualified and experienced to undertake Method 2 and 3 assessments and provide performance-based solutions, including short fire runs, application of assessed slope, and evaluation of radiant heat barriers.
Each site assessment considers the characteristics of the property, slope, potential bushfire threat, relevant fire danger index, surrounding land and vegetation. This enables us to provide tailored, accurate bushfire assessments for complex or high-risk sites that reflect real site conditions and the level of potential exposure and bushfire risk.
Our accredited practitioners provide reliable, professional BAL assessments, bushfire management plans and bushfire consulting services. With thousands of clients right across Australia, we are always open to new opportunities to help you navigate bushfire safety and compliance. Ready to get started with us?

Bushfire Attack Level (BAL) Ratings
A Bushfire Attack Level (BAL) rating is a means of measuring the severity of a building’s potential exposure to ember attack, radiant heat and direct flame contact. A BAL rating also determines the specific construction requirements for buildings in bushfire-prone areas. It is designed to improve the protection of buildings and their structural elements against bushfire attack.
BAL ratings range from BAL–Low through to BAL–FZ (BAL–Flame Zone), and are measured in increments of radiant heat (expressed in kilowatts/m2). Ratings can vary depending on a property’s location, nearby vegetation, slope, separation distances, surrounding land and the type of development. These characteristics form just some of the inputs into bushfire behaviour and the calculations that determine the flame length and the potential radiant heat.
Radiant heat from a flame decreases as the distance between the vegetation and building or proposed dwelling increases. This distance is used to determine the potential radiant heat experienced by the proposed building, and will change the specific construction materials that can be used.
Where a building is located greater than 100m from any classified vegetation, the BAL rating will be labelled as BAL-Low and does not require any specific construction requirements.
Construction standards can be increased to meet the requirements of your assessed BAL. Alternatively, vegetation modification surrounding the allotment or dwelling can be undertaken to reduce the BAL and consequent exposure level during a bushfire.
