How about the important issue that pre 1788 there was vast areas of natural
habitat types, e.g. mallee. Patch burning would impact small areas and most
animals had plenty of suitable habitat to move to for a while and many
successional stages could exist. Now natural habitat types are often
isolated patches, segregated by farmland, timber harvesting, urbanisation,
etc. Thus patch burning now has a totally different meaning from pre 1788,
because a patch can be most of an isolated remnant.

[Birding-Aus] the fire hazard reduction program
I think the basic problem is that you had a large workforce of people on
land managing it the whole time by mosaic burning. Since then the workforce
on the land has dwindled to such an extent that such a burning regime is now
impossible and all that can be achieved are very small scale conservation
burns, when funding, and wisdom, is available, and cosmetic and destructive
'hazard reduction burns' which are haphazard.
