However, the core factual claim—that most fires were started by lightning, not arson—is **substantially supported by evidence**.
**Lightning as Primary Cause:**
The RMIT ABC Fact Check investigation (published Feb 17, 2020) found that "in Victoria, emergency services personnel have been at pains to point out that lightning strikes caused the big fires — in East Gippsland and the north-east" [2].
According to the Parliamentary Library's 2019-20 bushfires FAQ, "the Victorian Country Fire Authority (CFA) and the NSW RFS" confirmed that "the majority of the 2019–20 fires in Victoria and NSW were caused by lightning" [4].
The CSIRO states that lightning is "most commonly" the cause of bushfires: "Bushfires are the result of a combination of weather and vegetation (which acts as a fuel for the fire), together with a way for the fire to begin – most commonly due to a lightning strike" [5].
One source found that lightning was responsible for "over 30% of the total fire outbreaks" in Victoria and NSW during 2019-2020 [7].
**Arson Numbers Exaggerated:**
Dutton's claim of 250 people charged with arson during the current crisis was factually misleading.
The ABC Fact Check investigation found that across all states and territories from August 2019 through February 2020:
- NSW: 55 people faced "legal action" (not all charged; includes cautions) [8]
- Victoria: No charges specifically linked to major fires (East Gippsland, North East) [9]
- Queensland: 109 dealt with (73 were juveniles; data doesn't distinguish "recklessly" vs "deliberately") [10]
- South Australia: 12 charged [11]
- Western Australia: 10 charged [12]
- Tasmania: 3 charges and 3 youth cautions [13]
- ACT: 0 charges for bushfire arson [14]
- NT: 6 charged [15]
The ABC concluded: "Taking all of this into consideration, the figures suggest that no more than 195 people have been either charged with deliberately or recklessly starting a fire.
The claim omits several important points:
**Nature of Large vs Small Fires:** The claim that arson was blamed doesn't distinguish between fire *numbers* and fire *size*.
While some small fires may have been deliberately lit, the major catastrophic fires—which caused most damage, deaths, and devastation—were predominantly lightning-caused.
Arson fires typically occur near populated areas and are detected sooner [18].
**The Role of Climate and Weather:** While the claim correctly identifies lightning as the primary cause, it omits the critical amplifying factors: the 2019-20 season was Australia's driest year on record (40% below average rainfall) and warmest year on record [19].
The CSIRO and CSIRO-Bureau of Meteorology both emphasized that climate change had extended fire seasons and increased the frequency of extreme fire weather [21].
**Arson as Secondary Issue:** The fact-checking indicates arson was not insignificant—just not the primary driver of the "unprecedented" severity.
But in the context of the current bushfire crisis, there is simply no evidence that arson was overwhelmingly responsible, or even moderately responsible" [22].
**Historical Arson Data:** Victorian data showed intentionally-caused bushfire offences actually *fell* in the year to September 2019, and were "well below the 10-year average" [23].
The second source (micky.com.au article about a digital strip search) has no relevance to bushfire causation and is not a credible source for this claim.
Some legitimate points: (1) arson is a real problem requiring police action, (2) fuel management and emergency preparedness matter regardless of climate policy, (3) not all fire seasons can be prevented by emissions reductions.
Dutton's "250 charged" figure was factually incorrect—the actual number was closer to 195, with significant double-counting and inclusion of juveniles and non-deliberate fires [29].
**Why This Matters:**
Misdirecting attention to arson downplayed the unprecedented climatic conditions (driest year on record, hottest year on record) that fundamentally enabled the bushfire crisis.
As the CSIRO explained: "Climate change doesn't cause fires directly but has caused an increase in the occurrence of extreme fire weather and in the length of the fire season across large parts of Australia since the 1950s" [30].
This is where climate change comes in" [31].
**Key Acknowledgment:** Fire prevention through fuel management, preparedness, and emergency response *are* important, and the Coalition did mobilize significant resources (6,500 ADF personnel deployed) [32].
The disagreement was not whether emergency response matters, but whether downplaying climate factors was an adequate response to an unprecedented crisis.
The claim correctly identifies that the Coalition blamed arson for the bushfire season and that most evidence shows lightning (not arson) was the primary ignition source.
However, the claim incompletely frames the issue by suggesting the Coalition's "blame on unprecedented arson" was simply false—when in fact the problem was more nuanced: (1) some arson occurred but was not "unprecedented" (below historical averages), (2) arson was secondary to lightning for major fires, and (3) the real issue was the unprecedented drought and heat conditions that made fires catastrophic regardless of cause.
The claim usefully corrects a misleading government narrative but undershoots by not emphasizing that climate/weather factors (which the government downplayed) were the true unprecedented elements of the 2019-20 season.
