About this Karnup suburb profile
Figures are from the ABS Census of Population and Housing 2021 (General Community Profile) for the Suburbs and Localities boundary matching Karnup. Where shown, 2016 values come from the 2016 State Suburbs (SSC) profile, linked via ABS geographic correspondence — boundaries are not always identical. Medians may be suppressed for very small areas. This is not financial or relocation advice — use it alongside current market data.
