Firefighters have stopped the spread of a grassfire threatening the town of Kangaroo Ground on Melbourne's outskirts but the blaze is still out of control.
An emergency warning has been downgraded to a watch and act alert for the grassfire at Kangaroo Ground, 26km northeast of the city centre.
During the emergency warning CFA spokesman Mick Harris said about 1000 people and 300 houses were in the direct area of the fire.
He said the fire covered about 11 hectares but was in inaccessible terrain, burning in a mixture of bush and open grassland.
Thirty tankers and five aircraft are fighting the fire.
Several fires have flared in the Tuesday afternoon heat but Mr Harris said there had been no property loss or injuries so far.
However, some firefighters have been treated for heat stress.
An emergency warning for the suburb of Diggers Rest and nearby town of Sunbury, 40km northwest of the Melbourne CBD, was discontinued after firefighters stopped the spread of the grassfire and brought it under control.
Firefighters also stopped the spread of a grassfire that was heading for the town of Little River, between Geelong and Melbourne.
