Fire authorities have given the all clear on a number of fires in Victoria's east after heavy rain last night.

Mount Hotham has had more than 100 millimetres of rain in two days.

Up to 70 millimetres has fallen on the Aberfeldy fire, north of Heyfield, which has been burning for more than a month.

The incident controller at Swifts Creek, Ben Rankin, says the rain has been heavy enough to declare the Harrietville Alpine South fire contained.

"[We've had] quite enough to dampen all the fuels and take any risk to the public out of this main fire now," he said.

An all-clear was issued for a 1,000 hectare fire north of Dargo yesterday and for a smaller fire burning in the Thomson Dam catchment this morning.

The Department of Sustainability and Environment (DSE) says the running edge of the fires has been extinguished by the rain and spotter planes will be in the air today looking for any remaining hotspots.
