A torched stolen car ignited a grass fire which burned about five acres of land at Invermay overnight.
Fire crews were called to the corner of Slatey Creek Road and Tallowwwood Rise about 4.45am to find the stolen sedan destroyed and the surrounding grass and scrub alight.
First crews on the scene called for 10 tankers to help fight the blaze, which at one stage was burning toward a property at the northern end of Slatey Creek Road.
CFA rostered duty officer Ben Townsend said it was "very frustrating" being called to yet another burning car.
It continues the spate of more than 30 car blazes which have happened this year.
Ballarat City firefighters attended with their pumper and another six tankers from CFA stations in the surrounding area bought the blaze under control with Forest Fire Management Victoria also attending to deal with dangerous trees left weakened by the fire.
