Sorry, but you're wrong: fires are getting worse and climate change is the primary driving factor.

We haven't had time to do all the analysis yet on the current fires in Australia, but basically many of the fires affecting Australia are occuring in areas and forest ecologies in which there's no historical record of fire having occurred nearby.

You're absolutely correct that fire is a complex topic that deals with:
-forestry management
-construction method in areas at risk for fire
-substantial annual variation in fire behaviour (aka the weather versus climate)

However, the overall extent of wildfire is clearly trending upwards and the costs associated with dealing with it (firefighting, insurance, construction methods) means that there's now a lot more areas that are essentially economically unbuildable due to climate change. The more we invest in avoiding climate change through controlling emissions, the less we destroy the economy through climate change. When you look at it at a global scale, reducing emissions is a heck of a deal relative to not building on anything touching a forest, not building anything close to the coast, etc.
