The 2020 Australia Royal Commission on bushfire prevention is a good resource, too. There are tons of things that could be done. Virtually none are being done nowadays, much less retrofitted to existing structures. Bushfire prevention via design is essentially in its infancy, much like earthquake safe designs took decades to become widespread in California after the 1933 quake. It wasn't like structures built in the 40s had "learned the lessons" and were earthquake proof. It has taken the better part of a century to get there.
