Suburb profile

Duffys Forest is a practical smaller community in Northern Beaches Council, well placed for families who want metro access without the inner-city squeeze. Long-term locals and family households define much of the community, with family life visible on every street. Schooling is a clear local strength compared with many peer areas.

Local green pockets are modest, with bigger outdoor outings usually found in neighbouring areas. Buses make it easy to move between neighbouring suburbs without relying on the car. Homes cost more here than in most comparable suburbs.

Crime trends have improved of late compared with the previous period. Tree-lined streets and established homes set the tone, with little pressure to reinvent the neighbourhood.

Desirability lands around average here: softer local dining and lifestyle amenities weighing on the result versus similar metro suburbs, even with community and employment, plus growth momentum 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 (~400), extrapolated at -0.2% 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.
