Another serious bushfire threat has flared in the Yarra Valley this morning, with Healesville and Toolangi now under "heavy ember attack".
A Country Fire Authority spokesman said 184 firefighters and 56 tankers are battling the blaze, with 505 hectares so far burnt out.
The nearby towns of Yarra Glen and Chum Creek are also under threat.
The bushfire has been dubbed the Maroondah/Yarra Complex, and is a combination of several blazes that have been burning in the district.
The fire was fanned overnight by strong winds.
Vic Country Fire Authority (CFA) spokesman Guy Sigley said today's temperatures were milder but the windy conditions were expected to cause problems for firefighters.
He said residents were under "heavy ember attack".
It is not yet known if any homes have been destroyed or lives lost.
