Are there parts of Oz that are presently inhabited but will become uninhabitable if these bush fires become an annual event? I've had a look at Rylstone and Kandos on Google Earth and see that these towns are planted right out in the bush. Perhaps sticking to the coast like the early settlers would be the way forward? The alternative I suppose would be massive deforestation around the towns to rid the area of combustible material - but I suspect that would simply bring a whole raft of other problems.....
