Housing, rent and growth
Housing & rent
ABS Census 2021Median rent is 43% of median household income. In the 30–50% rental-stress range
| Measure | Value | vs other SA suburbs |
|---|---|---|
| Median rent | $200/week | higher than 32% |
| Median household income | $466/week | higher than 1% |
| Rent as a share of income | 43% | higher than 100% |
| Median mortgage repayment | $184/month | higher than 0% |
| Average household size | 2.1 people | higher than 19% |
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 | +0.0% | higher than 12% |

| New homes approved per 1,000 residents 12 months to Aug 2026 | 2.9 | higher than 26% |
ABS publishes these for larger areas: figures are for “Goyder”, 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)
