What Hay Flat is known for: National parks, Green suburb, Heritage area

Suburb profile

Hay Flat is a welcoming smaller community in Yankalilla Council, with a settled community character. An older demographic makes it especially popular with retirees, with families and grandchildren still a visible part of community life. Shops and services are limited locally: a short trip to a nearby centre covers the fuller weekly shop.

Outdoor life is easy here, with generous parks and room for kids, dogs and weekend strolls. Day-to-day life is more car-oriented here than in denser, more walkable pockets. Housing is expensive relative to much of the state.

Reported crime has been rising recently. 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 (~100), extrapolated at +2.4% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Socio-economic

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.
