Bushfire Management Overlay (BMO, Victoria)

The Bushfire Management Overlay (BMO) is a Victorian planning overlay under Victoria Planning Provisions (VPP) Clause 44.06 that applies to land identified by the Victorian government as at high bushfire risk. Where the BMO applies, building work triggers a planning permit (in addition to the standard building permit), with CFA referral and a Bushfire Management Plan (BMP) required as part of the planning application. The BMO sits ABOVE the building-level bushfire-attack-level (BAL) trigger in NCC Volume Two H7, which applies in any bushfire-prone area. Builders in Victorian bushfire country need both pathways planned in.

The two-layer pathway in Victoria:

Layer	Trigger	Authority	Output
Planning permit (BMO)	VPP Clause 44.06 (BMO mapped land)	Council, with CFA referral	Planning permit + endorsed BMP
Building permit	NCC H7 (BPA mapped land) + state bushfire regulations	Private or council building surveyor	Building permit with bushfire conditions
Construction standard	AS 3959 BAL rating	Designer/Builder	Construction to BAL standard (e.g. BAL-29, BAL-FZ)

What the BMO requires:

Planning permit for any building work or extension; some minor exemptions.
Bushfire Management Plan (BMP): a site-specific plan covering:
- Defendable space: vegetation modification around the building.
- Water supply: dedicated water for firefighting (typically 10,000 L static water tank with CFA-compatible fittings).
- Access: vehicle access for fire trucks.
- Construction: AS 3959 BAL rating as a baseline, with site-specific upgrades.
CFA referral: the application is referred to the Country Fire Authority for comment and conditions before council determination.
Vegetation modification or removal: typically authorised within the planning permit.

Where the BMO applies:

Mapped on the Vic Plan maps (planning.vic.gov.au) as the BMO layer.
Typically applied to forested fringe areas of regional Victoria: Yarra Ranges, Macedon, Otways, Dandenongs, Mornington Peninsula, alpine zones.
Not the same as the Bushfire Prone Area (BPA) layer that triggers NCC H7 building requirements; BPA is broader and almost all of regional Victoria.

Common builder issues:

Discovering BMO post-design: the BMO is typically the bigger gate than NCC H7. A BMO planning permit can take 3-9 months. Discovering BMO after design lock-in derails the schedule.
Failing to satisfy CFA conditions: the CFA may impose defendable space, water, and access requirements that affect the site design (driveway turning circle, tank placement, vegetation clearance).
Bushfire Management Plan rejection: a poorly drafted BMP can come back with multiple rounds of CFA comments. Engaging a specialist bushfire consultant at the start avoids this.
Vegetation removal pre-permit: removing vegetation before the BMP is endorsed can attract penalties under both planning and environmental laws.

Cost band (Victorian, 2026 AUD ex-GST):

Item	Indicative cost
Bushfire consultant (BMP prep)	$3,500 to $8,000
Planning permit application	$500 to $2,500 (council fee)
CFA referral fee	$200 to $1,000
Water tank (10,000 L static + CFA fittings)	$4,000 to $10,000 installed
Defendable space works	$1,000 to $15,000 (site-dependent)
AS 3959 BAL-rated construction premium	5% to 25% over standard build

For builders.

Check Vic Plan BMO layer at lead (before quoting). If the lot is BMO, factor 3-9 months planning and a bushfire consultant into the program and cost.
Engage a bushfire consultant to prepare the BMP. Generic templates rarely satisfy CFA on a real site.
Plan defendable space, water, and access with the BMP from the start. Retrofitting these into a built-out design is expensive.
Coordinate the planning permit (BMO) and building permit (BAL) as a single program; don’t sequence them.

Also known as: BMO, Victorian BMO, bushfire planning overlay.
