Australia Burns Through the Black Summer

Over ten thousand fires burnt mainly across south-eastern Australia after an exceptionally dry year, in one of the most catastrophic fire seasons on record. Fires started early, from June 2019 in Central Queensland.

The 2019-20 Australian bushfire season, known as the Black Summer, was one of the most intense and catastrophic fire seasons on record. [S]
Exceptionally dry conditions and a lack of soil moisture, with early fires in Central Queensland, brought a premature start to the season from June 2019. [S]
Over ten thousand fires burnt, mainly in the south-east of the country. [S]
