Suburb profile
Set among the hills of Lockyer Valley Council, Mount Sylvia is a smaller community with bushland views and a cooler, leafier feel. Distance from the metro area around Brisbane is part of the appeal, with regional hubs closer to hand than the city. Established families and long-term residents give the suburb a settled feel, with a strong presence of young families throughout.
Everyday basics may be close by, but bigger shopping and services typically require a trip to a nearby centre. Open space is thinner than in many comparable suburbs, so residents often travel a little further for a longer park day. A car helps for most daily errands, with fewer amenities clustered within an easy walk.
Property prices run toward the upper end of the local market. This is a mature, settled pocket where the existing streetscape still defines the local character.

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 +1.6% 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.
