Suburb profile
Detention is a quieter smaller community in Circular Head Council, where peace, space and a country-town pace still dominate. Young professionals and new households shape much of the local mix, with family life visible on every street. The town centre holds its own, with enough local flavour to make staying close to home appealing.
Local shops are sparse, so a fuller set of amenities usually means travelling to a neighbouring town or regional hub. 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, though buses still link the suburb further afield.
Housing is more affordable than in many parts of the state. Reported crime has been falling recently.

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 (~50), extrapolated at +0.2% 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.
