Desirability score
- High desirability
Suburb profile
In Grant Council, Ob Flat keeps a rural calm, a smaller community with room to breathe and a strong local rhythm. Retirees and empty-nesters are well represented here, with multiple generations sharing the same neighbourhood. Everyday life leans local, with a handful of trusted shops, a familiar main street and neighbours who know your name.
Local green pockets are modest, with bigger outdoor outings usually found in neighbouring areas. Day-to-day life is more car-oriented here than in denser, more walkable pockets. Housing sits above the suburban middle: not the top of the market, but clearly pricier than average.
Reported crime has been falling recently. A trickle of new development is refreshing selected pockets without changing the overall feel.
Against similar regional towns, the suburb sits around average overall, mainly because local dining and lifestyle amenities lag behind, despite relative strength in community and employment. 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 (~500), 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.
