"It just doesn't stay down," Mr Miller said.

On Thursday, civilians, police and firefighters controlled a grassfire that threatened to jump Stony Hill Lane into the rainforest near Milton Primary School.

Mr Miller and other civilians were fighting a fire on the flats when they saw flames on the hill. Jackson Bower and the Manyana RFS, who were on their way to refuel in Milton, were first on scene.

"Jackson was with us on the flats. The young guys and other farmers have been the first responders a lot of the time."

It's the fourth time residents near Stony Hill have dealt with the Currowan fire. The first, which did most of the damage, was on New Year's Eve. The second time the fire burnt around Mount Pleasant on January 4.

On January 10, the fire was in the rainforest going towards Mr Miller's dairy and on Thursday it flared up on near Stony Hill Lane and on the flats north of Milton.

Mr Miller fears the threat of fire will remain until rain drenches the area. About 15mm fell last week.

"It's just too dry, it won't be out until we get rain," he said.

His biggest concern is the fire jumping over Stony Hill and burning through the Milton rainforest and also down to the western edge of Garrads Reserve.

"All we need is another dangerous day, and that's the worry."
