Australian Bureau of Statistics — Regional population (SA2), SEIFA 2021, Census 2021 (General Community Profile and Time Series Profile) and the Consumer Price Index. Facilities & amenities: OpenStreetMap contributors (ODbL), via the Overpass API.
Vintage
SA2 boundaries: ASGS 2021. Population is annual; SEIFA and the Census profile are five-yearly, so the sections carry different vintages. The 2016 “then and now” figures are mapped onto 2021 boundaries via the ABS Time Series Profile. Facility counts are an OpenStreetMap snapshot, refreshed quarterly. Last release: 27 Aug 2026.
Note
CPI is published at capital-city level only. No suburb-level price series exists in the ABS release.
