"At this stage, it appears at least 100 homes have been destroyed in yesterday's bush fires. Three people are unaccounted for. More than 30 people have been injured", the NSW RFS wrote on Twitter.
The authorities have been issuing multiple warnings, advising the public to leave various areas as bush or grass fires continued to burn in New South Wales and Queensland.
According to the NSW RFS, there were 77 bush or grass fires in the area, including 42 uncontained blazes, as of 06:30 a.m. on Saturday (19:30 GMT on Friday).
Local media also suggested that the risk of fires was expected to increase in the Western Australia region amid hot and windy weather there, adding that at least two people were killed and 7 were reported missing in the raging wildfires.
