Looking at UK media reports, it seems that some of the most destructive fires may have started as forest fires, but have developed into urban fires in which the main fuel is houses and vehicles.
Pictures show houses destroyed by fire whilst trees and bushes are still standing.
It seems that once a house burns, that the radiated heat ignites other structures and vehicles, in a chain reaction until a whole area is engulfed and destroyed.

Such fires have more in common with historic URBAN fires such as the great fires of London and Chicago. The fact that they started from a forest fire rather than a bakers oven or a cow kicking an oil lamp is not that relevant.

Major urban fires have historically resulted in improved fire safety, both prevention before the event, and a more effective response when fire breaks out.

Despite the cost, it seems to me that both fire prevention and fire fighting could be improved in high risk areas.

Fire prevention.
Require all new construction to be of brick, stone, or concrete. No more wooden buildings and no more plastic cladding.
All roofs to be fire resistant.
Require all property owners to remove all dry or dead vegetation that is within their property and within 100 feet of any structure.
Encourage the provision of swimming pools or decorative lakes, by tax breaks, in order that most properties will have a reserve water supply of many thousands of gallons.
Encourage all property owners to keep firefighting equipment to hand, an engine driven portable pump, suction and delivery hose etc. Such equipment is not that expensive, every home in a high risk area should be thus equipped.

Fire fighting by TPTB,
Provide more fire trucks and more firefighters.
Modern fire trucks are hugely costly and specialised vehicles that require highly trained firefighters to make good use of them.
I would propose an additional reserve fleet of much more basic equipment, that is cheaper to provide and simpler to use.
Something based on a army truck, with a pump driven by the road engine, and additional portable pump, suction hose and delivery hose, and a short ladder.
Such equipment could be staffed by anyone physically fit who has received a single weeks training.

When fire breaks out, the first attendance should be by a modern fully equipped fire truck staffed by highly trained fire fighters, just like at present.
They will be equipped and trained to handle all sorts of challenging situations including rescues from tall buildings, extrication from vehicle accidents, hazmat incidents and so on.

If however on arrival it is clear that the fire is large but relatively simple, such as a dozen houses on fire and many others threatened, than a radio message could be sent "send six reserve units"
The arrival of say six trucks each with a pump, short ladder, hose and a crew of say six men would help greatly. These reserve units would be affordable to provide in relatively large numbers.
