Suburb profile

Mount Colah is an outer metropolitan suburb of Sydney, in Hornsby Council. It is primarily residential, without a particularly distinct commercial centre or landmark identity.

Public transport coverage is exceptionally strong, placing it among the highest-ranked outer metropolitan suburbs. Reported crime is exceptionally low against comparable places. Reported offences have fallen 40% year on year, and university qualifications are among the highest in the peer group, with university qualifications 100% above the peer median, and working from home is a very strong feature of the suburb, with working from home 67% above the peer median. Trade-offs centre on higher housing costs and limited school access, with median house prices 44% above the peer median.

Mount Colah's appeal is better explained by housing, access and location than by a strong standalone precinct or destination.

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 (~9,250), extrapolated at +1.7% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Federal electorate from AEC federal division boundaries (2025 redistribution). Division-level results are official AEC figures from the latest general election, with by-election updates where applicable. The estimated suburb profile blends up to eight nearest ordinary polling booths in the same electorate using inverse-distance weighting from the suburb centroid — an approximation, not official AEC data. Nearest polling places are shown for reference.

IRSD decile (2021)

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.
