Current government PM2.5 readings within the official Melbourne - Inner SA4 boundary, with separate NASA GEOS-CF, CAMS and SILAM total-PM2.5 forecasts.
Updated · ABS 2026 region · concentrations, not an Australian AQI
Within 150 km, agencies report 4 other fire locations.
Straight-line distance from the Melbourne - Inner representative centre to the reported incident location, or to the mapped fire boundary where an agency has published one. A fire without a published boundary may extend closer than its reported location suggests.
The observed line is the hourly median across reporting monitors and the shaded range shows local variation. NASA GEOS-CF, CAMS and SILAM are separate total surface PM2.5 research forecasts sampled near the reporting-monitor centre. They are not smoke-only, official health forecasts or blended with observations.
