2021 Census figures: rents and incomes have risen since, so compare suburbs rather than reading today's prices. The rent share uses the median rent and the median income of all households (owners included), so it is a guide, not the share any one renter pays. The 30% benchmark is a common convention.
Growth & new homes

| New homes approved per 1,000 residents 12 months to Aug 2026 | 2.8 | higher than 25% |
ABS publishes these for larger areas: figures are for “Hackham - Onkaparinga Hills”, which contains this suburb. Approvals are dwellings approved, not yet built. Growth and new supply are change indicators, not a price forecast.

Data notes
- Population is estimated (medium confidence) from the ABS 2021 Census.
- Recorded crime counts offences reported to or detected by police where they occurred. That includes offences against visitors and businesses, so busy centres score higher than their resident risk.
- States classify offences differently, so ranks compare areas within the same state.
- sexual offences excluded / geo-masked at suburb level (SAPOL privacy)
