The fire danger was elevated across wider swathes of southern Australia on Thursday, with residents warned to avoid at-risk areas as smoke from bushfires choked Sydney and other major cities. Devastating fires along the country's east coast have claimed six lives and destroyed more than 500 homes since mid-October, with climate change and unseasonably hot, dry conditions fuelling the unprecedented blazes.
Now the fire danger has moved into states further south, with a so-called Code Red - the highest possible fire risk in Victoria - being declared in the state's northwest for the first time in a decade.
What that means is that if we see fires in those areas they will be fast moving, they will be unpredictable, they will be uncontrollable, emergency management commissioner Andrew Crisp told reporters.
Country Fire Authority chief Steve Warrington told people living in rural areas to leave for the safety of cities.
We are saying, 'do not be there, do not be there when a fire occurs, because you will not survive if you are there', he said.
There is a good chance if a fire occurs that your home will be destroyed.
The fire danger was also elevated to severe in the island state of Tasmania off mainland Australia's southeastern coast, where a total fire ban was declared.
Two bushfires in the state's northeast did not pose an immediate threat to residents, the Tasmania Fire Service said.
For the second time in two days, smoke from bushfires blanketed Sydney, Australia's biggest city and home to more than five million people, sending air quality plummeting to hazardous levels.
More than 110 fires are still burning in worst-hit New South Wales and neighboring Queensland, while in South Australia more than 40 fires broke out during catastrophic fire conditions Wednesday.
