Suburb profile
Mount Saint Thomas sits up in the Wollongong Council hills, a smaller community where elevation and tree cover define the mood. Residents are mostly families and working professionals, with plenty of young families in the mix. Local schools rate highly against similar suburbs.
Everyday cafés are limited locally, with the wider metro area covering the bigger food and entertainment trips. There is not a full local strip here: residents typically travel to a nearby suburb for a broader choice of shops and services. Buses make commuting and cross-suburb trips straightforward.
Property sits in a premium price band and is harder to enter for many buyers. The suburb still has an emerging character, as newer residents settle in and local identity forms.
Desirability lands below average here: softer safety weighing on the result versus similar metro suburbs, even with growth momentum, plus community and employment holding up better. Limited access to some essential local services also trimmed the result.

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 (~1,750), extrapolated at +0.5% 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.
