THURSDAY: Roma CIB is currently investigating the cause of a massive blaze that burnt a house to the ground at Yuleba last night.

The fire tore through the Creek Street house about 8.45pm, completely destroying the structure.

Yuleba Rural Fire Brigade prevented the fire spreading to a neighbouring dwelling, before fire fighters from Roma and Wallumbilla arrived at the scene.

It is believed no one was inside the house at the time.

Queensland Fire and Emergency Services South-West Region Area Commander Roma Paul Kelly commended the actions of all crews that attended.

"As with any old Queenslander, when they collapse on themselves, it is a very difficult thing to get water onto the fire," he said.

"Old pine burns very well, and as it was declared a crime scene we didn't disturb the scene."
