Firefighters are becoming fed up as the disturbing trend of car fires continues to persist.
Two vehicles, a mere 750 meters away from each other, were torched Sunday night, leaving one firefighter to say he was "getting sick of it".
The first came just after 9pm when firefighters were called to an incident near Seymour's on Lydiard Hotel.
One vehicle was quickly extinguished at the scene.
Seven hours later a second car for set alight in Soldiers Hill, this time on Havelock Street.
Firefighters were called to the fire about 4am and had to work quickly to minimise property damage as the blaze took place underneath a car port.
Police remain outside of the property.
Ballarat Police confirmed the incidents were being looked at by the Criminal Investigation Unit.
Police did not comment on whether they believed the incidents were linked.
All of this comes after Lucas Fire Brigade station officer Brenton Smith said exposure to contaminant and smoke was a 'real concern' to firefighters who were attending a number of car fires in Ballarat on Sunday.
"Our people are exposed to smoke and carcinogens when a car is on fire and there is the risk of things like explosions you can get from any fire," he said.
"We want to minimise the amount of times our people are exposed to this."
Police are urging anyone with information regarding either of these incidents to submit an anonymous report to Crimestoppers on 1800 333 000 or online at www.crimestoppersvic.com.au.
