Suburb profile

In Kangaroo Island Council, Willoughby keeps a rural calm, a smaller community with room to breathe and a strong local rhythm. Genuine distance from the metro area around Adelaide is part of the character: quiet streets, big skies and a town that looks after itself. An older demographic makes it especially popular with retirees, with a community of people who commute and work locally.

Everyday basics may be close by, but bigger shopping and services typically require a trip to a nearby centre. Parks and open space are a real strength relative to many comparable suburbs, easy for walks, sport and weekend downtime. Day-to-day life is more car-oriented here than in denser, more walkable pockets.

Homes are neither a bargain nor a premium buy against the wider market. Light infill development is updating a few streets while the wider area stays largely unchanged.

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 +1.3% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Socio-economic

IRSAD decile (2021)
5/10
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.
