Suburb profile
St Johns is a residential smaller community in Light Council with a familiar suburban feel. A strong local centre anchors daily routines, while the surrounding region adds variety for weekends away. Working households and growing families are the backbone of local life, with a strong presence of young families throughout.
Local amenities are on the light side, so many everyday needs are met by travelling to a neighbouring suburb or town. Open space is thinner than in many comparable suburbs, so residents often travel a little further for a longer park day. A car helps for most daily errands, with fewer amenities clustered within an easy walk.
Housing sits in the middle of the local market: neither cheap nor premium.

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 (~0), extrapolated at +2.4% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Federal electorate from AEC federal division boundaries (2025 redistribution). Division-level results are official AEC figures from the latest general election, with by-election updates where applicable. The estimated suburb profile blends up to eight nearest ordinary polling booths in the same electorate using inverse-distance weighting from the suburb centroid — an approximation, not official AEC data. Nearest polling places are shown for reference.

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.
