it (the annual bushfire) is a natural part of the reproductive cycle of the aussie gumtree...  

The GumSeed dropped under the groundcover foilage; uses the heat and scorch of those fire, to go on to it's next stages of germination

Unfortunately it's not part of the reproductive cycle of Koalas, Kangaroos etc, or mammal life in general.

OK, yes I remember those fires being on the news. 

Some years ago I was in QLD where they were doing a controlled burn off, around 2012 I think.
