Suburb profile
Semaphore is a coastal mid-sized suburb where beach life and relaxed outdoor living shape the local character. Retirees and empty-nesters are well represented here, with families and grandchildren still a visible part of community life. For coastal suburbs, the café and dining scene is notably rich, with locals returning to favourite spots.
Parks and open space are a real strength relative to many coastal suburbs, easy for walks, sport and weekend downtime. Daily life works well on foot, with buses and trains also serving the suburb. Homes cost more here than in most comparable suburbs.
Crime reports are up on the previous period. The built character feels historic and distinctive, with heritage detail visible throughout.
Against similar coastal suburbs, the suburb sits around average overall, mainly because community and employment lag behind, despite relative strength in growth momentum, plus schools and education.

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.
