Suburb profile
Seaforth is a practical mid-sized suburb in Northern Beaches Council, well placed for families who want metro access without the inner-city squeeze. The area suits established families and long-term locals, with plenty of young families in the mix. The suburb has a clear multicultural mix alongside longer-term local households.
Schooling is a clear local strength compared with many peer areas. Green space punches above what many metro suburbs offer, with parks and playgrounds woven through the suburb. Most routine trips are on foot, while buses cover longer journeys across the metro area.
Housing is expensive relative to much of the state. Renewal is happening in measured doses, with new development complementing what is already there.
Against similar metro suburbs, community and employment, plus local dining and lifestyle amenities stand out and the overall desirability rating is excellent, with growth momentum and safety 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 (~7,500), 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.
