Bushfire-prone area (BPA)

Bushfire-prone area is a state-mapped designation that triggers NCC H7P5 and AS 3959 construction. Distinct from planning overlays like Victoria's BMO.

A bushfire-prone area (BPA) is a land designation that triggers NCC 2022 bushfire construction requirements for any Class 1 or 10a building work on the property. NCC Performance Requirement H7P5 mandates bushfire-resistant construction in any designated bushfire-prone area; the DTS pathway is full compliance with AS 3959-2018 (NCC 2022 H7D4), driven by a site-specific BAL assessment.

Each state runs its own bushfire-prone area mapping under different agencies. NSW’s map is published by the NSW Rural Fire Service. Victoria layers a planning overlay (the Bushfire Management Overlay, or BMO) on top of its designated bushfire-prone area mapping. Queensland, WA, SA, TAS, NT, and ACT each maintain their own mapping under the relevant state fire service, planning department, or equivalent.

BPA is distinct from a planning overlay. A planning overlay like Victoria’s BMO sits above the BPA designation and adds planning controls (siting, vegetation management, building permit conditions) separate from the NCC construction requirements. A property can be in a BPA without being in an overlay, in an overlay without being in a BPA, or in both. Construction requirements track the BPA designation; planning controls track the overlay.

If a property sits within a BPA, the build needs a BAL assessment under AS 3959-2018 (typically prepared by a BPAD accredited practitioner) and construction details meeting the assessed BAL across cladding, eaves, windows, doors, decks, and roof.

Building permit lodgement requires the BPA status to be confirmed and the BAL documented. Building in a BPA without an assessed BAL and matching construction is a compliance breach the certifier should catch.

Also known as: BPA, designated bushfire-prone area, bushfire-prone land.
