Suburb profile
Seacombe Heights is a hillside smaller community in Marion Council, with elevated streets and a greener, quieter pace. Working households and growing families are the backbone of local life, with plenty of young families in the mix. The suburb has a clear multicultural mix alongside longer-term local households.
Parks and open space are a real strength relative to many metro suburbs, easy for walks, sport and weekend downtime. A car helps for most daily errands, though buses still link the suburb further afield. Housing is expensive relative to much of the state.
Reported crime has been falling recently. A trickle of new development is refreshing selected pockets without changing the overall feel.
The overall desirability read is around average, pulled by softer schools and education compared with similar metro suburbs, though community and employment, plus growth momentum 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 (~1,500), extrapolated at +0.6% 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.
