Suburb profile
Garden Island is a welcoming smaller community in Unincorporated SA, with a settled community character. A mature community gives the area a calm, settled social fabric. 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. A car helps for most daily errands, with fewer amenities clustered within an easy walk. Housing sits in the middle of the local market: neither cheap nor premium.
Crime trends have improved of late compared with the previous period. This is a mature, settled pocket where the existing streetscape still defines the local character.

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 (~0), extrapolated at -4.8% average annual growth since 2011. It is illustrative only — not an official ABS forecast.
