Suburb profile
Antechamber Bay offers a slower smaller community life in Kangaroo Island Council, with open surrounds and a close-knit community feel. It sits a long way from Adelaide and other major hubs, so daily life runs on a self-contained, local timetable. Retirees and empty-nesters are well represented here, with multiple generations sharing the same neighbourhood.
Local shops are sparse, so a fuller set of amenities usually means travelling to a neighbouring town or regional hub. Parks and open space are a real strength relative to many comparable suburbs, easy for walks, sport and weekend downtime. A car helps for most daily errands, with fewer amenities clustered within an easy walk.
Property prices are middling for the area: fair relative to what is nearby. Tree-lined streets and established homes set the tone, with little pressure to reinvent the neighbourhood.

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 +1.1% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Socio-economic
- IRSAD decile (2021)
- 5/10
- IRSD decile (2021)
- 5/10
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.
