Flowerdale fire rages for fourth day

The Kinglake community, as well as residents in Melbourne's east and north, have been told they may be able to see smoke on Friday due to windy conditions and backburning. 

On Thursday, 71-year-old Flowerdale man Bill Sangster told the Nine network he took full responsibility for the blaze which was a "bloody accident" sparked by an angle grinder he was using on a fence.

He was arrested by Victoria Police earlier in the week but they later confirmed it wasn't a deliberately lit fire.

Fire crews have constructed control lines ahead of potentially dangerous conditions.

The area is under a high fire danger rating, with strong northerly winds expected and temperatures in the low 30s.
