Dozens missing as Australian bushfires kill 135

Weary firefighters and rescuers pulled the remains of dozens of people from charred buildings on Monday as the toll from Australia's deadliest bushfires rose to 135.

"Everybody's gone. Everybody's gone. Everybody. Their houses are gone. They're all dead in the houses there. Everybody's dead," cried survivor Christopher Harvey as he walked through the town of Kinglake, where most people were killed.

Police believe some of the fires, which razed rural towns near the country's second biggest city, Melbourne, were deliberately lit and declared one devastated town a crime scene.

The bushfires are the country's worst natural disaster in more than a century, and will put pressure on Rudd to deliver a broad new climate policy.

One massive bushfire tore through several towns in the southern state of Victoria on Saturday night, destroying everything in its path. Many people died in cars trying to flee and others were killed huddled in their homes, yet some escaped by jumping into swimming pools or farm reservoirs.

The inferno was as tall as a four-storey building at one stage and was sparking spot fires 40 km ahead of itself as the strong winds blew hot embers in its path.

Wildfires are a natural annual event in Australia, but this year a combination of scorching weather, drought and tinder-dry bush has created prime conditions.

The fires, and major floods in Queensland state in the north, will put pressure on Rudd, who is due to deliver a new climate policy in May. Green politicians are citing the extreme weather to back a tougher climate policy.

Adding to the nation's grief, authorities in northern Queensland searched unsuccessfully for a five-year-old boy who they believe was killed by a crocodile when he chased his pet dog into the flooded Daintree River.

Scientists say Australia, with its harsh environment, is set to be one of the nations most affected by climate change.

The Victorian bushfire tragedy is the worst natural disaster in Australia in 110 years. In 1899, Cyclone Mahina struck Australia's northern Cape York, killing more than 400.

Thousands of firefighters continued to battle the main fires and scores of other blazes across Victoria on Monday, as well as fires in neighbouring New South Wales state.

While cooler, calmer conditions helped firefighters, 10 major fires remained out of control in Victoria. But the week-long heatwave that triggered the inferno was over.

The fires burnt out more than 330,000 ha of mostly bushland in Victoria, but a number of vineyards in the Yarra Valley were also destroyed. The Insurance Council of Australia said it was too early to estimate the bill.

The small town of Marysville was sealed off by police as forensic scientists searched through the rubble for evidence.

As dawn broke in the town of Whittlesea, near Kinglake, shocked residents wandered the streets, some crying, searching for loved ones still missing.

The previous worst bushfire tragedy in Australia was in 1983, when 75 people were killed.
