Suburb profile
Tiwi Islands offers a slower smaller community life in Tiwi Islands Council, with open surrounds and a close-knit community feel. It sits a long way from Darwin and other major hubs, so daily life runs on a self-contained, local timetable. A younger crowd gives the area energy, with a strong presence of young families throughout.
With limited local amenities, residents regularly travel to a neighbouring town for shops, appointments and a wider choice. Open space is thinner than in many comparable suburbs, 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.
Housing is more affordable than in many parts of the state.

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 (~200), extrapolated at -0.5% 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.
