Suburb profile
In Yorke Peninsula Council, Koolywurtie keeps a rural calm, a smaller community with room to breathe and a strong local rhythm. Residents are mostly families and working professionals, with plenty of young families in the mix. Local shops, markets and community spots keep everyday life grounded in the town itself.
Local green pockets are modest, with bigger outdoor outings usually found in neighbouring areas. A car helps for most daily errands, with fewer amenities clustered within an easy walk. Homes are neither a bargain nor a premium buy against the wider market.
Reported crime has been falling recently. Light infill development is updating a few streets while the wider area stays largely unchanged.

ABS Estimated Resident Population allocated to this suburb from SA2-level data. Not an official ABS suburb count.
Methodology
Figures are allocated from ABS Estimated Resident Population at Statistical Area Level 2 (SA2), using 2021 Census share within overlapping SA2 regions. Where Census data is unavailable, area overlap is used instead.
The dashed chart line is a simple growth-trend estimate to June 2030 (~100), extrapolated at +0.6% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Socio-economic

ABS Socio-Economic Indexes for Areas (SEIFA), 2021 release — the latest available, derived from the 2021 Census. Deciles rank suburbs nationally from 1 (lowest) to 10 (highest).
What do IRSAD and IRSD measure?
IRSAD — Index of Relative Socio-economic Advantage and Disadvantage. Combines indicators of advantage (e.g. high income, skilled occupations) and disadvantage. Higher decile = more advantaged relative to other Australian areas.
IRSD — Index of Relative Socio-economic Disadvantage. Focuses on disadvantage only (e.g. low income, unemployment, limited education). Higher decile = less disadvantage nationally.
A new SEIFA edition typically follows each census; the ABS has not announced a release date beyond 2021.
