NSW Bushfire Study: 94% of Homes Lost Within 100m of Vegetation 2026

A new study has found that 94% of homes destroyed in New South Wales during the black summer bushfires were within 100 metres of flammable vegetation. The research, published in the International Journal of Wildland Fire, analyzed the 2,475 homes lost in NSW during the 2019-2020 fires and confirms the effectiveness of current risk maps while raising questions about future safety standards.

Key Findings on Bushfire-Destroyed Homes

The study, led by Associate Professor Owen Price from the University of Wollongong, examined the proximity of destroyed homes to flammable vegetation such as trees. It found that the vast majority fell within the 100-metre buffer zone that authorities use to identify properties most at risk.

This buffer is a critical component of bushfire-prone land maps, which firefighters use for community outreach and planning authorities use to determine construction standards for new homes and renovations in high-risk areas.

• 94% of homes lost in NSW were within 100 metres of flammable vegetation.
• The study analyzed 2,475 homes destroyed during the 2019-2020 black summer bushfires.
• The 100-metre buffer is used in bushfire-prone land maps for planning and firefighting.
• Researchers warn that global heating may require extending recommended distances.
• The NSW Rural Fire Service says findings reinforce the need for higher fire standards in high-risk areas.

Why the 100-Metre Buffer Matters

The 100-metre buffer zone is a key tool for identifying properties at risk from bushfires. It helps planners assess how bushfire-resistant new homes and renovations should be, and guides firefighters in planning local outreach activities.

According to the research, the fact that most destroyed homes were within this zone is an endorsement of the risk maps used by authorities. It suggests that the maps are accurately identifying the areas most vulnerable to bushfire attack.

Implications for Future Bushfire Safety

While the findings validate current risk mapping, the research warns that as global heating generates ever-worsening fire conditions, firefighters may have to extend the recommended distances between homes and vegetation to keep homes safe.

The NSW Rural Fire Service said the findings reinforced how homes in high-risk areas should be built to higher fire standards as it prepares for a potentially challenging fire season.

What This Means for Homeowners in Bushfire-Prone Areas

For homeowners in bushfire-prone areas, the study underscores the importance of understanding your property's risk. If your home is within 100 metres of flammable vegetation, it falls into the high-risk category identified by authorities.

This means that building or renovating to higher fire standards is crucial. The NSW Rural Fire Service emphasizes that homes in high-risk areas should be constructed with fire-resistant materials and designs to withstand ember attack and radiant heat.

The Broader Context of Black Summer

The black summer bushfires of 2019-2020 were unprecedented in their scale and destructiveness. Across the country, more than 3,000 homes were lost, 33 lives were taken, and almost 3 billion native animals were killed or displaced.
