Good old Australia, it has been doing this as long as white man has been keeping records. I love it when I hear that the Aboriginals "managed the environment" They were nomads in low numbers compared to todays population they lit fires by rubbing 2 sticks together so the thought of them doing cold burns during the cooler months just beggars belief. Funny how some story told becomes fact with nothing to back it up. Sure their camp fire might have got out of control but the didn't "manage" that they walked in the other direction, left the fires to burn till the rains came and put them out, just how it has happened again this year. The big difference now is that our population is expanding into the bush in big numbers ans when a fire gets going it puts large numbers of houses and lives at risk. None of it is rocket science.
