A torrential rainfall across New South Wales and the Australian Capital Territory has extinguished around one-third of active bushfires in a single day.

The rainfall put out 20 active fires in the largest single-day drop in wildfires since the season began. There are still 42 fires active on the coast. The rain also caused some flooding.

As a result of the rain, Sydney saw it wettest day on record in around 15 months.
