Australia is in the grip of a devastating fire season, six people have been killed, hundreds of homes destroyed and over a million hectares razed.
David Bowman is the director of the Fire Centre at the University of Tasmania's school of natural sciences and says Australia should retro fit houses to make them heat and smoke proof among many other measures.
