Suburb profile

William Creek offers a slower smaller community life in Unincorporated SA, 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. A younger crowd gives the area energy, with a strong presence of young families throughout.

With limited local amenities, residents regularly travel to a neighbouring town for shops, appointments and a wider choice. Open space is thinner than in many comparable suburbs, so residents often travel a little further for a longer park day. Day-to-day life is more car-oriented here than in denser, more walkable pockets.

Purchase and rent costs sit on the more affordable side of the local range.

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 -4.0% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Socio-economic

IRSAD decile (2021)
3/10
IRSD decile (2021)
2/10

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.
