Onkaparinga Unley

Onkaparinga and Unley are contrasting parts of Greater Adelaide. Unley is a compact, high-income area where 46.5% of adults hold a bachelor degree or higher and 30.8% of households earn over $3,000 a week. It is highly accessible, described as a walker's paradise, with almost all homes within a 15-minute walk of schools and health services. In contrast, Onkaparinga is much larger and more suburban, where 89% of homes are separate houses and 85.9% have three or more bedrooms. It is far less walkable, with typical walk times to public transport taking 69 minutes.

Everyday life in both areas shares similar patterns in some ways, such as the number of people per home and the proportion of residents who provide unpaid care. They also have similar average school sizes and population growth rates since 2021. However, some gaps are widening; the difference in bachelor degree qualifications and high weekly earnings has grown since 2011, as has the share of recent overseas arrivals in Unley.
