Bushfire Attack Level (BAL) Assessments & Bushfire Management Plans in Queensland

If you’re developing or building in a bushfire hazard area in Queensland, you’ll likely need a Bushfire Attack Level (BAL) assessment and a Bushfire Management Plan (BMP) before your development application is approved. Queensland Ecologists prepares both - giving you a single, qualified consultant to handle the ecology and bushfire requirements together.

What Is a Bushfire Attack Level (BAL) Assessment?

A BAL assessment determines the level of bushfire exposure a building site faces from surrounding vegetation. The assessment follows AS 3959:2018 - Construction of Buildings in Bushfire-Prone Areas and classifies your site into one of six BAL ratings:

BAL - LOW - Very low bushfire risk. No specific construction requirements.
BAL - 12.5 - Low bushfire risk. Ember attack possible. Basic construction upgrades required.
BAL - 19 - Moderate bushfire risk. Increased radiant heat exposure. Enhanced construction standards.
BAL - 29 - High bushfire risk. Significant radiant heat and ember attack. Substantial construction upgrades.
BAL - 40 - Very high bushfire risk. Direct flame contact possible. Major construction requirements.
BAL - FZ (Flame Zone) - Extreme bushfire risk. Direct exposure to flames. Highest construction standards or site may be undevelopable.

Your BAL rating directly determines the construction standard your building must meet and influences the siting, design, and landscaping of your development.

What Is a Bushfire Management Plan?

A Bushfire Management Plan (BMP) is a comprehensive document that addresses how bushfire risk will be managed for a development. It goes beyond the BAL assessment to cover:

Vegetation management - identifying hazardous vegetation and specifying fuel-reduction zones
Asset Protection Zones (APZs) - cleared and maintained buffers between buildings and bushland
Access and egress - ensuring safe evacuation routes and emergency vehicle access
Water supply - fire-fighting water provisions for the development
Landscaping requirements - species selection and planting layouts that reduce fire risk
Ongoing maintenance obligations - fuel load management and vegetation clearing schedules

When Do You Need a BAL Assessment or Bushfire Management Plan?

In Queensland, bushfire assessments are triggered by State Development Assessment Provisions (SDAP) State Code 21 - Development in a bushfire hazard area. You’ll need one if:

Your site is mapped within a bushfire hazard area on the State Planning Policy (SPP) mapping
You are lodging a development application (DA) for a new dwelling, subdivision, or material change of use
Your local council’s planning scheme overlay identifies bushfire risk on your lot
You are building in or adjacent to remnant vegetation, grassland, or bushland
Your project involves a community infrastructure or vulnerable use (aged care, childcare, hospitals) in a hazard area

Many SEQ councils - including Brisbane, Gold Coast, Sunshine Coast, Moreton Bay, Logan, Redlands, Ipswich, Scenic Rim, and Noosa - have significant areas mapped as bushfire-prone.

Our BAL Assessment & Bushfire Management Plan Process

Desktop review - We review SPP bushfire hazard mapping, vegetation mapping, topography, and your development plans
Site inspection - Our ecologist visits the site to classify vegetation type, measure slope, assess fuel loads, and determine setback distances in accordance with AS 3959
BAL calculation - We calculate the Bushfire Attack Level for each building envelope using the Method 2 detailed assessment under AS 3959:2018
Bushfire Management Plan - We prepare a BMP addressing SPP Natural Hazards (Bushfire) performance outcomes, including APZ specifications, vegetation management, access, water supply, and landscaping
Lodgement support - We respond to any State Assessment and Referral Agency (SARA) information requests and support your application through to approval

Why Choose Queensland Ecologists for BAL Assessments?

As ecologists, we bring a unique advantage to bushfire assessments. BAL calculations depend heavily on correctly classifying vegetation - something many generic bushfire consultants get wrong. Our team:

Has 20+ years of vegetation classification experience across Queensland regional ecosystems
Holds CEnvP (Certified Environmental Practitioner) certification
Can combine your BAL assessment with any required ecological assessment, vegetation management plan, or environmental management plan - saving you time and money with a single consultant
Services all of South East Queensland and regional Queensland

Common BAL Assessment Locations in Queensland

We regularly complete BAL assessments and Bushfire Management Plans across SEQ, including properties in the Sunshine Coast hinterland, Gold Coast hinterland, Scenic Rim, D’Aguilar Range, Mount Tamborine, Samford Valley, Springfield, and rural Moreton Bay.
