Sydney smoke haze: bushfire reduction burns suspended to allow air to clear

Air quality rated 'poor' for second day in a row, as NSW Health warns conditions could aggravate respiratory issues

Hazard reduction burns across Sydney have been suspended for at least 24 hours to allow smoke from earlier burns to clear.

The New South Wales Office of Environment and Heritage dropped the air quality level in the harbour city to "poor" for a second day on Wednesday, as Sydneysiders woke up to hazy conditions and the sharp smell of smoke in the air.
