One Free Website That Could Save You From Buying in a Bushfire Zone

Last summer changed how I look at properties in the hills. The fires did not reach metropolitan Melbourne, but they got close enough to remind everyone that bushfire risk is not theoretical. It is a due diligence item that belongs on every checklist.

And there is a free website that tells you everything you need to know in thirty seconds.

I am constantly surprised by how many buyers, including experienced investors, skip this check. They will spend four hours reading a building inspection report about minor cracks in the plaster, but they will not spend thirty seconds checking whether the property sits in a designated bushfire zone. The consequence of that oversight can be catastrophic: uninsurable properties, $50,000 to $100,000 in mandatory building upgrades, and resale discounts of 15 to 25 per cent 1.

The free tool: VicPlan (and how to use it)

The Victorian government's planning tool, VicPlan, is publicly accessible and free. It maps every planning overlay across the state, including both Bushfire Management Overlay (BMO) and Wildfire Management Overlay (WMO).

Here is how to check any property in under thirty seconds.

Step one: go to mapshare.vic.gov.au/vicplan or search for VicPlan in any browser.

Step two: enter the property address in the search bar.

Step three: look at the overlays listed in the property information panel. If you see BMO (Bushfire Management Overlay) or WMO (Wildfire Management Overlay), the property sits in a designated bushfire-prone area 2.

That is it. Thirty seconds. No login. No subscription. No account.

The information is definitive. It comes directly from the state planning database. If the overlay is listed, the property is affected. If it is not listed, the property is clear.

I run this check on every single property we assess, even in suburbs where bushfire risk seems improbable. Urban fringe properties, properties backing onto reserves, properties near remnant bushland, all of these can carry a BMO or WMO that the selling agent conveniently forgot to mention.

What BMO and WMO mean for buyers

Bushfire Management Overlay (BMO): this is the most restrictive classification. Properties with a BMO must comply with Australian Standard AS 3959 for construction in bushfire-prone areas. Any new construction, renovation, or extension must meet specific material and design requirements that can add 20 to 40 per cent to build costs 3.

For example: standard timber framing may need to be replaced with steel. Windows may require bushfire-rated glass. External cladding may need to be non-combustible. Decking may need to be built from bushfire-resistant materials. These are not optional upgrades. They are mandatory compliance requirements.

On a $110,000 granny flat build, bushfire compliance could add $22,000 to $44,000 to the construction cost. That changes the ROI calculation dramatically.

Wildfire Management Overlay (WMO): this is a less restrictive classification that applies to areas with moderate bushfire risk. The construction requirements are less onerous than BMO but still impose additional costs and design constraints.

Insurance impact: properties in BMO and WMO zones face significantly higher insurance premiums. In some cases, insurers refuse to cover properties altogether, leaving the owner uninsured or reliant on specialist high-risk insurers at two to five times the standard premium 4.

I had a client who purchased a property in the Dandenong Ranges without checking the overlay. The BMO designation meant their planned renovation required bushfire-rated construction throughout. The renovation budget went from $80,000 to $130,000. And their annual insurance premium was $4,200 instead of the $1,800 they had budgeted. That is $2,400 per year in additional holding costs that was entirely avoidable.

Where bushfire overlays catch people by surprise

You might assume that bushfire risk only applies to rural and semi-rural properties. That assumption is dangerous.

In metropolitan Melbourne, BMO and WMO overlays exist in suburbs that most people consider urban. Properties in the Dandenong Ranges (Belgrave, Olinda, Sassafras), the outer east (Warrandyte, Park Orchards, Research), and parts of the Mornington Peninsula all carry bushfire overlays. Some of these suburbs are less than 30 kilometres from the CBD 5.

The overlay does not follow suburb boundaries. It follows vegetation mapping. A property on one side of a street can be BMO-affected while the property directly opposite is clear, because the affected property backs onto bushland and the opposite property faces an open sports ground.

This is why checking VicPlan for every individual property is non-negotiable. Suburb-level generalisations are unreliable. The overlay is property-specific.

Our investment strategy deliberately avoids BMO and WMO zones. Not because the properties are inherently bad, but because the additional construction costs, insurance premiums, and resale discounts reduce returns below our minimum threshold. When we can achieve 5 to 8 per cent yield in suburbs with no bushfire risk, there is no reason to accept the additional cost and complexity of a bushfire-affected property 6.

The broader due diligence lesson

The bushfire overlay check is one item in a larger due diligence framework that we apply to every property. The full checklist includes:

• Zoning (General Residential, Residential Growth, Low Density Residential)
• Heritage overlay
• Design and Development Overlay
• Environmental Significance Overlay
• Special Building Overlay (flooding)
• Bushfire Management Overlay
• Easements and covenant restrictions
• Contaminated land notices

Every one of these can be checked for free using VicPlan and the Section 32 vendor statement. Every one of them can materially affect the property's value, your renovation options, and your long-term return.

The tragedy is that most of these checks take less than five minutes, cost nothing, and can save you tens of thousands of dollars. But the majority of buyers skip them because they do not know the tools exist or they trust the selling agent to disclose everything.

Selling agents are legally required to disclose known material facts. But what they know and what the planning database contains are not always the same thing. An agent who has never checked VicPlan for the property cannot disclose an overlay they are unaware of 7.

Do your own due diligence. Use the free tools. Thirty seconds on VicPlan can be the difference between a solid investment and a financial disaster.

Across our 350-plus transactions, we have rejected approximately 15 per cent of shortlisted properties based on overlay checks alone. That is 15 per cent of properties that looked good on the surface but carried hidden risks that only showed up in the planning database. Every one of those rejections saved a client from a problem they never knew existed.
