SYDNEY (REUTERS) - Sydney was wreathed in hazardous smoke on Thursday (Oct 31) as strong winds fanned dozens of bushfires across Australia's east coast, prompting health warnings for the city that is home to more than 5 million people and the state of New South Wales (NSW).

Firefighters were battling to control more than 50 wild fires that remained ablaze across NSW, the state's Rural Fire Service (RFS) said. There were no reports of injuries caused by the fires by late morning local time, but strong winds have blown the dangerous smoke across large parts of NSW.

The RFS said the smoke was unlikely to clear for at least 24 hours, while hot, dry conditions are expected to linger for several days more - exacerbating the threat of more fires as authorities try to assess the damage of blazes now extinguished.

"Dust may aggravate existing heart and lung conditions and cause symptoms like eye irritation and cough," saidMr Richard Broome, director of environmental health, NSW Health.

"Symptoms can occur for several days after dust is inhaled, so people with the chronic conditions need to be vigilant with their treatment programmes." One of the biggest fires in recent days was recorded in Lake Cathie, 379km north of Sydney - which has destroyed more than 2,000ha of a national park.

The fire is now under control, though the area is a prime breeding ground for koalas, stoking fears that hundreds will have been killed by the fires.

"Based on our calculations, with a minimum 60 per cent mortality rate, about 350 koalas will be lost," Ms Sue Ashton, president of the Port Macquarie Koala Hospital, told Reuters.

"It's terrible, it's absolutely devastating. It's a national tragedy." Ms Ashton said seven rescuers on Thursday entered the burnt national park in an effort to rescue any injured koalas.
