Suburb profile
Thirlmere anchors everyday life in Wollondilly Council, a regional mid-sized suburb with its own identity and rhythm. Families and commuters make up much of the community, with family life visible on every street. Weekends tend to revolve around local favourites: a café, a market run, a walk through town.
Parks and open space are a real strength relative to many regional towns, easy for walks, sport and weekend downtime. Buses make commuting and cross-suburb trips straightforward. Homes cost more here than in most comparable suburbs.
Crime trends have improved of late compared with the previous period. Active development is adding new homes and refreshed pockets throughout the suburb.
Against similar regional towns, community and employment, plus growth momentum stand out and the overall desirability rating is good, with schools and education less decisive.

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 (~6,750), extrapolated at +2.6% 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.
