Sydney, the country’s most populous city, was blanketed in a thick haze for the fourth consecutive day, pushing it into a rare and repeat appearance in the list of top ten cities with the worst air pollution in the world, Reuters reported.
Even as a cooler change brought some relief for firefighters battling scores of blazes burning for days across four states, many of the 7.5 million residents of New South Wales switched from contemplating evacuation to avoid rapidly advancing wildfires to hiding indoors from the smoke.
“The streets are deserted as people try and avoid being outside as much as possible,” Barry Hollman, mayor of the town of Bourke, some 800km (497.1 miles) northwest of Sydney, told Reuters.
Air pollution in Bourke was at 15 times higher than recommended safe levels as strong winds whipped up both bushfire smoke and dust that has accumulated following three years of drought across Australia.
“I went out to check on people and in some parts visibility is less than 100 meters,” Hollman said. “The dust and smoke is everywhere.”
The smoke haze brought particulate pollution, which can be absorbed into the bloodstream, creating what officials said were the highest levels of pollution recorded in New South Wales.
Health officials said 73 people had sought treatment for respiratory conditions over the past week, twice normal levels.
At some stages in recent days, the state capital of Sydney reached as high as No. 8 on the Air Visual global rankings of cities with the worst air pollution in the world, ahead of Jakarta and Shenzhen and only just behind Mumbai.
Bushfires have left at least four people dead and destroyed more than 400 homes since the start of November. Fires are still burning in New South Wales, Victoria, South Australia and Queensland states.
The crisis has put pressure on Prime Minister Scott Morrison as critics say the Australian leader has not done enough to address the impact of climate change, which meteorologists have said was extending the length of the fire weather season.
Bushfires are common in Australia but the fire season has begun much earlier than usual, with temperatures soaring above 40°C well ahead of the start of the southern summer and high winds hitting the drought-parched landscape.
Morrison on Friday again rejected any links between the fires and his conservative government’s policies, including support for the coal industry.
