Victoria's Emergency Management Commissioner Tim Wiebusch said firefighters were battling around 30 active blazes as the state's fire danger rating hit the highest "catastrophic" level. Temperatures were forecast to reach 46 degrees Celsius (115 degrees Fahrenheit), with damaging winds expected to make conditions "undefendable" in some areas, authorities said. Dozens of communities have been evacuated and many parks and campgrounds closed as the fires continue to spread. "If you don't leave now, it could result in your life being lost," Wiebusch said.
