Arson? Lack of hazard reduction? Nothing new? This video looks at what fire chiefs and scientists say is the REAL cause of the 2019-2020 fires in Australia, in response to amateur theories proposed by media commentators and bloggers. -- Potholer54

CORRECTIONS:
1) The pronunciation of Bourke rhymes with 'Turk' not 'torque.'

2) The police report on the screen shows 53 legal actions for failing to comply with the fire ban, I accidentally said 57 in the voiceover.

3) One poster has commented: "You said that 83% of hazard reduction burns have been carried out. But that was referring to all bushfire protection works mentioned, not just hazard reduction.
The hazard reduction percentage is 76%."
I have not had time to verify this.
