The indigenous Australians used to start fires at a specific time of year for the particular area, and on a particular cycle of n years for a particular area. Some of these cycles and times are known. This meant that, for thousands of years, the fuel load in the eucalypt forests were reset on a regular schedule. Not only do we not do this anymore, the schedules that worked for millennia probably wouldn't work any more due to the change of rainfall patterns, temperatures and moisture content. Indigenous Australians certainly would have seen some huge fires, but according to soil / sediment and tree sampling, probably nothing like the ones going on right now.
