Housing, rent and growth

Housing & rent

ABS Census 2021

Median rent is 20% of median household income. Below the 30% stress benchmark

Average household size2.2 people higher than 26%

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.

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)
