Methodology
Bushfire risk methodology
How Districts reports mapped bushfire overlays and listing mentions — not a BAL assessment.
Last reviewed
What this metric means
Districts reports whether a loaded official bushfire overlay intersects the parcel, or whether a listing observation mentions bushfire. Mapped overlay exposure is not a site-specific bushfire attack level (BAL) assessment, and it is not an insurer determination.
What Districts shows
When an official bushfire overlay is loaded and intersects the parcel, research answers can say Districts maps that overlay on the address and can name the layer.
When the loaded bushfire category was queried and no overlay was identified, Districts says no mapped bushfire overlay was identified in the datasets currently used — not that the lot cannot be bushfire prone.
Hazard cards also keep listing language separate: “the published listing reports…” is not an official all-clear, and a listing that reports none is not a completed official query.
Data used
The dedicated official bushfire layer currently catalogued is Western Australia’s Bush Fire Prone Areas dataset from the Department of Fire and Emergency Services, published through Landgate. Victorian planning overlays may also be classified as bushfire when their names match. Queensland, including the Sunshine Coast, has no official bushfire overlay in the current catalog — those lots are listing evidence unless another loaded overlay is classified as bushfire.
Listing bushfire attributes are public marketing observations collected by Districts. They are not an official mapping authority, and a listing that reports none is not a completed official query.
How Districts calculates it
Source quote: an intersecting official bushfire overlay is reported from the planning extract. Districts does not invent a BAL rating or a “high/medium/low” score on top of that overlay.
Districts calculation: the same parcel-intersection method as other planning overlays. A queried-empty bushfire category means the loaded layer did not return an intersecting overlay.
There is no national bushfire engine and no BAL calculator. Research answers about mapped bushfire are emitted only when the planning extract has a bushfire overlay or a queried-empty bushfire category. A listing-only mention does not create that official answer.
Evidence and missing data
Official mapped intersection is the only path that supports a government overlay claim.
A listing hint is marketing evidence. A missing official layer is unknown, not “not bushfire prone.”
