Suburb profile
Second Valley is a residential smaller community in Yankalilla Council with a familiar suburban feel. A mature community gives the area a calm, settled social fabric. Local amenities are on the light side, so many everyday needs are met by travelling to a neighbouring suburb or town.
Outdoor life is easy here, with generous parks and room for kids, dogs and weekend strolls. Day-to-day life is more car-oriented here, with buses covering longer trips across the wider area. Purchase and rent costs sit on the more affordable side of the local range.
Crime reports are up on the previous period. Tree-lined streets and established homes set the tone, with little pressure to reinvent the neighbourhood.

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 (~150), extrapolated at +2.4% 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.
