Suburb profile
Blue Rocks is a remote locality in Tasmania, in Flinders Council. It is close to the Flinders Island.
Socio-economic advantage is a strong feature of the suburb, and university qualifications are a relative strength, with university qualifications 117% above the peer median, and recorded road-crash rates are lower than in comparable places, with recorded road crashes 63% below the peer median. The clearer weaknesses are thinner local amenities and thinner mapped green cover within the suburb boundary, with local amenities 80% below the peer median.
Blue Rocks is a better fit for people who value socio-economic advantage and university qualifications more than local amenities.

ABS Estimated Resident Population allocated to this suburb from SA2-level data. Not an official ABS suburb count.
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 +0.9% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Australian Taxation Office Taxation Statistics 2023–24, individuals Table 25. Figures describe taxpayers who live in postcode 7255 — not a suburb-level official statistic. Rental investment is the share of local taxpayers reporting rental income or loss, not the share of local properties owned by investors.
Percentiles rank this postcode among unique postcodes in TAS, so suburbs that share a postcode are not counted twice. Dollar figures are compared with Australia-wide ATO medians from the same release. Median net rent is among taxpayers who reported the rent label and can be negative.

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).
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.
