Heavy smoke has covered Australia's largest city, Sydney, as scores of bushfires rage across the region.
Officials say strong winds brought smoke overnight from an inland blaze north of the city, pushing Sydney's air quality to beyond "hazardous" levels.
On social media, locals described waking up to hazy skies and the stench of smoke in their homes.
About five million people live in the state capital of New South Wales, which has been affected for weeks by fires.
Six people have died in bushfires in the north of the state since October.
