People who visit the Australian high country know how badly it has been impacted by bushfires over the past decade.
In Victoria, we experienced the Eastern Alps fire of 2003, which burnt 1.3 million hectares, and also in 2006/07 which burnt almost 1.3 million hectares. Then over the summer of 2012/13, the Aberfeldy-Donnellys Creek and Harrietville fires also burnt large areas of the mountains. Some sections have been burnt three times in a decade, with loss of significant stands of Alpine Ash and snow gums.
