Scorching heatwave conditions continue to grip much of Australia's southeast, keeping authorities on high alert as fire conditions grow increasingly unpredictable. 

Temperatures soared across parts of Victoria and South Australia yesterday, breaking nearly a dozen local heat records and nearing 50C. 

And the scorching temperatures are set to continue, with forecasts from the Bureau of Meteorology indicating that the heat is set to linger until the weekend in areas away from the coast.  

Australia Correspondent Steve Price told Mike Hosking that one fire officer said that the radiant heat is so extreme it can kill you before you even get hit by a bushfire.
