A giant dust storm has blanketed communities across south-east Australia, turning skies orange and raising concerns about air quality.
Authorities issued a public health alert for New South Wales on Thursday as the 500km-wide (310 miles) dust band reached the city and caused flight delays.
Many regions in New South Wales (NSW) have had poor visibility.
Authorities said the storm was driven by strong winds picking up dry soil.
The problem has been exacerbated by a drought that has affected the entire state of NSW since August, according to Australia’s Bureau of Meteorology.
