Crime & safety
FY2024–25, 2-yr pooled. Recorded incidents: NSW Bureau of Crime Statistics and Research (BOCSAR); adjusted to the ABS Crime Victimisation Survey; ABS ERP population denominator. All CC BY 4.0. Percentile is the population-weighted rank among suburbs in the same state — higher means more reported crime. Ranks are never compared across states, because each police force counts offences under its own rules.
