Suburb profile

Marion Bay is a coastal smaller community a long way from Adelaide, where beach life and a quieter rhythm set the tone. A mature community gives the area a calm, settled social fabric, with families and grandchildren still a visible part of community life. With limited local amenities, residents regularly travel to a neighbouring town for shops, appointments and a wider choice.

Green space punches above what many coastal suburbs offer, with parks and playgrounds woven through the suburb. Day-to-day life is more car-oriented here, with buses covering longer trips across the wider area. Homes are relatively cheap compared with the wider market, which keeps entry costs lower.

Crime trends have improved of late compared with the previous period. This is a mature, settled pocket where the existing streetscape still defines the local character.

Versus similar coastal suburbs, the suburb reads below average on desirability, chiefly because community and employment, plus local dining and lifestyle amenities trail behind. 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 (~250), extrapolated at +0.8% 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.
