Suburb profile
Cornwallis is a welcoming smaller community in Hawkesbury Council, with a settled community character. A strong local centre anchors daily routines, while the surrounding region adds variety for weekends away. The area suits established families and long-term locals, with family life visible on every street.
Local amenities are on the light side, so many everyday needs are met by travelling to a neighbouring suburb or town. Local green pockets are modest, with bigger outdoor outings usually found in neighbouring areas. Day-to-day life is more car-oriented here than in denser, more walkable pockets.
Homes cost more here than in most comparable suburbs. 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 (~50), extrapolated at +1.3% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Socio-economic
- IRSAD decile (2021)

- IRSD decile (2021)
- 3/10
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.
