Estimated: cities without a monitor
South Australia cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.
| City | 7-day estimate |

| Adelaide Hills | ≈ 5 µg/m³ |
| Mount Gambier | ≈ 5 µg/m³ |
| Mount Barker | ≈ 4 µg/m³ |
| Whyalla | ≈ 3 µg/m³ |
| Gawler | ≈ 5 µg/m³ |
