Suburb profile
O'Sullivan Beach wears its coastal identity openly, a smaller community built around sand, sea and an easy outdoor rhythm. Established families and long-term residents give the suburb a settled feel, with plenty of young families in the mix. Fitness and outdoor sport options are a real part of local life, not just a distant club trip away.
Outdoor life is easy here, with generous parks and room for kids, dogs and weekend strolls. Reasonably walkable — many errands reachable on foot or by bus, and buses help with longer trips. Housing is more affordable than in many parts of the state.
Crime reports are up on the previous period. Construction and infill projects are noticeably reshaping parts of the area.
Versus similar coastal suburbs, the suburb reads around average on desirability, chiefly because community and employment trail behind.

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 (~2,050), extrapolated at +1.1% 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.
