Suburb profile
In Onkaparinga Council, Tatachilla is a settled smaller community where everyday shopping leans on neighbouring suburbs. The area suits established families and long-term locals, with family life visible on every street. Dining is thinner on the ground than in busier metro pockets, so many residents head to neighbouring suburbs for a night out.
Local green pockets are modest, with bigger outdoor outings usually found in neighbouring areas. Day-to-day life is more car-oriented here than in denser, more walkable pockets. Housing is expensive relative to much of the state.
Crime trends have improved of late compared with the previous period. The streetscape feels settled and established, with older homes giving the area a familiar, lived-in look.
The overall desirability read is below average, pulled by softer parks and green space compared with similar metro suburbs, though schools and education, plus community and employment remain brighter spots. Limited access to some essential local services also trimmed the result.

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 (~300), extrapolated at +3.0% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

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.
