Two towns in eastern Victoria remain under threat from bushfires, which have destroyed at least 10 houses.
About 700 firefighters are battling the blazes.
The ABC reports cooler conditions have helped crews, but a change in the wind direction is causing spot fires.
It is believed the destroyed houses were all in the tiny community of Darlimurla.
Country Fire Authority duty officer Greg Patterson says they are working to protect the townships of Boolara and Mirboo North in Gippsland.
The fires were started deliberately and about 4500 hectares have been burned.
Temperatures above 40 degrees have been recorded in Victoria and South Australia for the past three days.
