UPDATE:
Six main fires are still burning uncontrolled in Victoria, including those at Kinglake, Yea-Murrindindi, Maroondah-Yarra, Bunyip, Churchill and Beechworth-Murmungee.
Fire authorities have said blazes around Mount Riddell and Mount Juliet, east of Melbourne, are not expected to threaten nearby residents, but ash may fall around Healesville.
Department of Sustainability and Environment spokesman Stuart Ord said heavy resources would be thrown into fires near Healesville over the weekend to establish containment lines before hotter weather returns.
'We have got about 50 to 60 bulldozers just in that area working on the fire edge,' Mr Ord said.
'We're throwing everything on that to try to get containment lines on it.'
