Suburb profile
Colosseum offers a slower smaller community life in Gladstone Council, with open surrounds and a close-knit community feel. A mature community gives the area a calm, settled social fabric, with multiple generations sharing the same neighbourhood. The town centre holds its own, with enough local flavour to make staying close to home appealing.
Open space is thinner than in many comparable suburbs, so residents often travel a little further for a longer park day. A car helps for most daily errands, with fewer amenities clustered within an easy walk. Purchase and rent costs sit on the more affordable side of the local range.
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.

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 (~250), extrapolated at +2.8% 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.
