Victorian Premier John Brumby says the death toll from the bushfires will rise well beyond 200 and the coroner had conceded as much. "There are still a large number of people - in excess of 50 - who are unconfirmed and essentially these are people who the coroner believes are already deceased, but are not yet identified," he told reporters in Mudgegonga on Tuesday.

"When you see these areas from the air it's just a sickening feeling, particularly Kinglake and Marysville there's just hundreds and hundreds of houses completely obliterated so the toll will continue to rise."
Earlier on Tuesday, the official death toll rose to 173. Victorian police say they are closing in on a suspected arsonist they believe lit one of the massive fires.
Crime Department Assistant Commissioner Dannye Moloney is close to releasing a photofit of a suspected arsonist operating in the Churchill area in Gippsland just days before last Saturday's inferno.
"There are suspicious fires out there," Mr Moloney said."The Churchill fires, as far as we can conclude at this stage, must be considered as suspicious and that is being investigated as we speak."All the other fire sites are obviously slowly but surely being investigated by our arson experts and as the reports come in and as they go through their scientific examinations, we will establish the causes of what happened out there last Saturday and Sunday."
The Churchill Jeeralang fire has so far ravaged 40,000ha. It has a 130km perimeter.
Twenty-one people have so far been found dead in the ruins of the Gippsland inferno.
