Buying Property in a Bushfire Prone Area
Bushfire-prone properties can be great value — or a costly mistake. Before you sign, understand the BAL rating, insurance costs, building requirements and the 2050 risk trajectory for the specific address you’re considering.

8 things to check before buying in a bushfire zone
This is the due diligence checklist conveyancers and buyers’ agents recommend for any bushfire-prone property purchase.
Get the BAL rating for the specific address
The BAL rating is property-specific — determined by vegetation type, slope gradient and distance from classified bushfire-prone land. A ClimateNest report gives you the BAL rating for your exact address before you make an offer.
Check if the building meets current BAL standards
Older buildings may have been constructed before BAL requirements applied. Check if the building meets the current AS 3959 standard for its BAL rating. Non-compliant buildings may be uninsurable or require costly upgrades.
Get insurance quotes before exchange
Get at least 3 bushfire insurance quotes before exchanging contracts. Premium variation between insurers for bushfire-risk properties is high — and some insurers will decline to cover high-BAL properties entirely.
Inspect the asset protection zone (APZ)
An effective APZ (cleared vegetation zone between the building and bushland) significantly reduces risk. Check the width and maintenance condition of the APZ and whether it complies with state fire authority requirements.
Review the fire history near the property
A ClimateNest report includes fire event history within 5km over the last 20 years. Repeated fire history in the immediate area is a significant risk signal.
Understand the 2050 risk trajectory
CSIRO projects fire weather severity to increase across most of southern and eastern Australia under all climate scenarios. A property at moderate fire risk today may be high risk by 2040–50.
Factor BAL building costs into renovation plans
Any new building work, extensions or renovations must comply with AS 3959 for the property's BAL rating. For BAL-40 or BAL-FZ properties, construction costs are significantly higher than standard — factor this into purchase price and future plans.
Have an emergency plan
If you proceed with a bushfire-prone area purchase, develop a formal Bushfire Survival Plan with your state fire authority (NSW RFS, CFA VIC, DFES WA). Know your trigger conditions and planned evacuation route.
BAL rating: what it costs you
| BAL Rating | Construction premium | Insurance loading | Resale impact |
|---|---|---|---|
| BAL-LOW | Nil | Nil | None |
| BAL-12.5 | Minimal (~$5K) | +10–30% | Minimal |
| BAL-19 | Low (~$10–20K) | +20–50% | Minor discount |
| BAL-29 | Moderate (~$20–40K) | +50–150% | 5–10% discount |
| BAL-40 | High (~$40–80K) | +100–300% | 10–15% discount |
| BAL-FZ | Very high ($80K–$150K+) | Withdrawal risk | 15–25%+ discount |

Frequently asked questions
Do I need a BAL assessment before buying a bushfire-prone property?
There is no legal requirement for buyers to obtain a formal BAL assessment before purchase, but it is strongly recommended. A formal BAL assessment from a fire consultant typically costs A$300–600. A ClimateNest report gives you an indicative BAL rating at address level as part of a broader climate risk assessment from A$69.
Can I get a mortgage on a BAL-40 or BAL-FZ property?
Generally yes, but lenders may require evidence of buildings insurance as a condition of approval. If insurance is unavailable or unaffordably expensive (as can be the case for BAL-FZ properties), this can affect your ability to obtain finance.
What happens to bushfire-prone properties that can't get insurance?
Properties that cannot obtain bushfire insurance face a shrinking buyer pool (lenders require insurance for mortgages), accelerated value decline and increasing difficulty at resale. The risk of being in this position is why due diligence before purchase is so important.
Are bushfire-prone areas getting bigger in Australia?
Yes. Following the 2019–20 Black Summer fires, several NSW and QLD councils revised and expanded their bushfire prone land maps. CSIRO projects that the geographic extent of high fire weather conditions will increase across most of southern and eastern Australia as temperatures rise.
