Suburb - Risks

Flood area coverage + optional polygon map

GET/v1/suburbs/{suburb_name}/risks/flood6¢ per call

Share of the suburb AREA covered by modelled flood overlays.

Area, not properties. For the share of DWELLINGS affected — the figure our own reports headline — use GET /v1/suburbs/{suburb_name}/risks/property-hazard-counts.

To answer where the flood zone is, pass geojson=true. The response then includes the actual modelled flood polygons clipped to the suburb boundary, suitable for a street map, plus truncation/simplification metadata. Do not infer street location from coverage_pct alone.

Exact suburb identifier required. Exact ABS Suburb and Locality (SAL) name, e.g. Burwood (NSW) — many suburbs carry a state suffix. If starting from free text or an unverified bare name, first call GET /v1/geocode/suburb?q=<text>, then use the exact data[].area_name it returns. Suburb data endpoints do not guess a state or typo-correct names.

Price: 6¢ per call.

Path parameters

suburb_namestringrequired

Exact ABS Suburb and Locality (SAL) name, e.g. `Burwood (NSW)` — many suburbs carry a state suffix. If starting from free text or an unverified bare name, first call `GET /v1/geocode/suburb?q=<text>`, then use the exact `data[].area_name` it returns. Suburb data endpoints do not guess a state or typo-correct names.

Query parameters

geojsonbooleanoptional

When true, add a `geojson` FeatureCollection of the flood polygons clipped to the suburb boundary (default false — response unchanged).

Responses

Successful Response

application/json
SuburbRiskfields returned to you
area_namestringalways returned

Suburb (SAL) name.

area_levelstringalways returned

Always 'suburb'.

namestringalways returned

Risk overlay name — 'Bushfire' or 'Flood'.

coverage_pctnumberalways returned

Share of suburb area inside the overlay (%).

value_unitstringalways returned

Unit for coverage_pct — '% of suburb area'.

risk_bandstringmay be null

Coarse band — 'low' / 'moderate' / 'high'. Currently flood only.

geojsonobjectmay be null

GeoJSON FeatureCollection of the hazard polygons for this layer, ST_Intersection-clipped to the suburb boundary and simplified for browser use. Present only when the request passes `?geojson=true`; absent (and the response byte-identical to before) otherwise.

geojson_metaobjectmay be null

Clip / simplify / truncation metadata for `geojson` (clip method, simplify tolerance, coordinate precision, feature cap, and whether the size cap truncated the output). Present only with `?geojson=true`.
