About this Castle Rock suburb profile
Figures are from the ABS Census of Population and Housing 2021 (General Community Profile) for the Suburbs and Localities boundary matching Castle Rock. Where shown, 2016 values come from the 2016 State Suburbs (SSC) profile, linked via ABS geographic correspondence — boundaries are not always identical.
