Queensland Fire and Rescue Services (QFRS) were alerted to the fire in a vacant home listed for sale, near the corner of Campbell and Holley streets, just before midday.

QFRS area director Inspector Ross Mutzelburg said the fire started inside the empty home and spread to the roof.

"The crew on the ladder were extinguishing the old air conditioning system on the roof and then we had breathing apparatus teams inside fighting the fire and pulling down parts of the ceiling to make sure it didn't spread above the ceiling unnoticed," he said.

Insp Mutzelburg said reports by a number of people allowed fire services to attack the blaze quickly, extinguishing it within 15 minutes of arriving at the scene.

Real estate agents who had the home listed for sale were also at the scene inspecting the damage.

The property was completely smoke logged and blackened during the blaze and the windows had been shattered by the heat. It is understood the owners of the home moved out a week prior to the incident, but Insp Mutzelburg said it was pleasing to hear the smoke alarms installed in the home were still doing their job.

"It's always good to hear the smoke alarm going off and getting those calls," he said.

"If there would have been someone in there they would have had warning and time to get out of the house."
