ABS 2021 POA to SA2 residential Mesh Block share. Postal Areas approximate Australia Post postcodes. Records are allocated fractionally by each SA2's share of residential Mesh Blocks in the POA, with total Mesh Block share used only when a POA has no residential Mesh Blocks. This is a screening estimate, not premises-level geocoding.
Recent certificate cohorts can be incomplete while installations move through validation.
Coverage: 335 postcodes allocated to 246 WA SA2s. Refresh contract: Monthly CER release.
