Suburb profile
Cogra Bay is a residential smaller community in the local area with a familiar suburban feel. An older demographic makes it especially popular with retirees. Local shops, markets and community spots keep everyday life grounded in the town itself.
Local amenities are on the light side, so many everyday needs are met by travelling to a neighbouring suburb or town. Local green pockets are modest, with bigger outdoor outings usually found in neighbouring areas. 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. This is a mature, settled pocket where the existing streetscape still defines the local character.

Federal electorate from AEC federal division boundaries (2025 redistribution). Division-level results are official AEC figures from the latest general election, with by-election updates where applicable. The estimated suburb profile blends up to eight nearest ordinary polling booths in the same electorate using inverse-distance weighting from the suburb centroid — an approximation, not official AEC data. Nearest polling places are shown for reference.

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.
