Housing, rent and growth
Housing & rent
ABS Census 2021Median rent is 20% of median household income. Below the 30% stress benchmark
| Measure | Value | vs other SA suburbs |
|---|---|---|
| Median rent | $200/week | higher than 32% |
| Median household income | $1,019/week | higher than 17% |
| Rent as a share of income | 20% | higher than 63% |
| Median mortgage repayment | $1,400/month | higher than 50% |
| Homes that are rented | 16% | higher than 48% |
| Owned outright | 64% | higher than 96% |
| Social housing | 0% | higher than 29% |
| Average household size | 1.8 people | higher than 7% |
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
ABS Regional Population · Building Approvals| Measure | Value | vs other SA areas |
|---|---|---|
| Population growth, 5 years 2020–2025 | +9.5% | higher than 84% |
| Population growth, last year 2024–2025 | +1.6% | higher than 84% |
| New homes approved, 12 months 12 months to Aug 2026 | 76 | higher than 60% |
| New homes approved per 1,000 residents 12 months to Aug 2026 | 10.9 | higher than 82% |
ABS publishes these for larger areas: figures are for “Yankalilla”, 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)
