Sydney – A third person was confirmed dead on Wednesday in devastating bushfires that engulfed Australia’s southeast coast this week and a fourth was missing and feared dead, as navy ships rushed to provide supplies and assist with evacuations.

Twelve people have now lost their lives in fire-related deaths across Australia since blazes broke out a few months ago, including three volunteer firefighters, after a three-year drought in large parts of the nation created tinder-dry conditions.

Fanned by soaring temperatures, columns of fire and smoke blackened entire towns on Monday and Tuesday, forcing thousands of residents and holidaymakers to seek shelter on beaches. Many stood in shallow water to escape the flames.

Bushfires have destroyed more than 4 million hectares (10 million acres) and new blazes are sparked almost daily by extremely hot and windy conditions and, most recently, dry lightning strikes created by the fires themselves.

Cooler conditions on Wednesday gave the country a moment to count the cost of the fires, although there were still more than 100 blazes in New South Wales (NSW) state alone and thousands of firefighters on the ground.
