Suburb profile
Life in Semaphore South revolves around the coast, with the feel of a smaller community that never strays far from the water. City outings and nearby suburbs add variety without undoing the coastal pace of everyday life. Long-term locals and family households define much of the community, with family life visible on every street.
A car helps for most daily errands, though buses still link the suburb further afield. Homes cost more here than in most comparable suburbs. Local crime has been trending higher of late.
The built character feels settled, with heritage streetscapes lending the area a sense of history.
Desirability lands below average here: softer parks and green space, plus local dining and lifestyle amenities weighing on the result versus similar coastal suburbs, even with community and employment holding up better. Limited access to some essential local services also trimmed the result.

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 (~1,050), extrapolated at +0.4% 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.
