Not saying this is a net good - more of a silver lining / glass half full.

Rainforest areas especially haven't evolved with much fire tolerance and these places are being gutted. We will lose many species of plants and animals to extinction from these fires without major conservation efforts (which are underway).
From the articles I've read, it seems that the scale of this year's fire is partly due to the lack of controlled fires and clearing of accumulated dead plants over the recent past.
If so, this year's fires might actually be closer to what bushfires used to be before humans arrived in Australia. Though perhaps they occurred less often (many of the current fires probably have an human origin).
Regarding the risk of extinction of animal species, I think this is also because the range of these vulnerable species vastly shrunk because of humans, not necessarily because of the fires per se.
There has indeed been a lack of controlled burning, but that's because the planned clearance was itself inhibited by hotter, drier conditions earlier in the year.
The causes of ignition are statistically very poorly understood. What is known, however, is that convictions for arson have been in steady decline, and 2019 had the lowest levels of intentionally causing a bushfire for at least a decade.
Not only that, but despite the proximity to human habitation, the current fires have been (so far, touch wood) less fatal than the catastrophic bushfires of 2009. The Royal Commission into those fires found a lack of preparation and poor advice. Since then, policy and awareness of risk has changed dramatically for the better - including a reduction in the sources of inadvertent/accidental human causes of ignition.
To sum up, both suggestions fail to support the conclusion "this is how it always was".
Hopefully, you're also reading articles from less gaslit publications.
Most of the time they have a human origin. Not necessarily arson, though it is not uncommon (but it's difficult to catch perpetrators), but human activities make accidents happen (cigarettes, BBQ, cars, electric circuits, controlled fire gone awry, etc).
I never said or suggested that that current situation in Australia was mostly arson or that it is how it always has been. But equally I do not subscribe to the current hysteria. I think that Australian bushfires before humans arrived must have been quite a thing.
A problem we have is that it is difficult to have a measured discussion on these topics these days as illustrated by how my previous comment is downvoted and your ridiculous suggestion about the sources of my readings.
