Suburb profile
Life in Semaphore Park revolves around the coast, with the feel of a mid-sized suburb 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.
Parks and open space are a real strength relative to many coastal suburbs, easy for walks, sport and weekend downtime. Buses and trains connect the area to surrounding suburbs, keeping the wider city within easy reach. Housing is expensive relative to much of the state.
Reported crime has been rising recently. Active development is adding new homes and refreshed pockets throughout the suburb.
The overall desirability read is around average, pulled by softer community and employment compared with similar coastal suburbs, though growth momentum remain brighter spots. 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 (~4,700), extrapolated at +0.7% 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.
