Suburb profile
In Serpentine-Jarrahdale Council, Mardella keeps a rural calm, a smaller community with room to breathe and a strong local rhythm. Long-term locals and family households define much of the community, with a strong presence of young families throughout. The pace is unhurried, with local businesses and community spots doing the heavy lifting.
Open space is thinner than in many regional towns, so residents often travel a little further for a longer park day. Day-to-day life is more car-oriented here than in denser, more walkable pockets. Buyers typically pay more than the metro middle for a home here.
Reported crime has been falling recently. This is a mature, settled pocket where the existing streetscape still defines the local character.
Against similar regional towns, the suburb sits around average overall, mainly because local dining and lifestyle amenities, plus growth momentum lag behind, despite relative strength in housing affordability, plus community and employment. Limited access to some essential local services also trimmed the result.

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 (~550), extrapolated at +2.4% 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.
