Australian Bureau of Statistics — Regional population (SA2), SEIFA 2021, Census 2021 (General Community and Time Series profiles) and the Consumer Price Index. Amenities from OpenStreetMap contributors (ODbL), via the Overpass API.
Vintages
SA2 boundaries follow ASGS 2021. Population is annual; SEIFA and the Census profile are five-yearly. The 2016 “then and now” figures are mapped onto 2021 boundaries via the ABS Time Series Profile, so those comparisons are approximate. Data current to 28 August 2026.
A caveat
The CPI is published for whole capital cities, not suburbs, so “cost of living” covers Brisbane as a whole. Everything on a suburb page is the most recent ABS figure for that area.
