Queensland Deputy Premier Cameron Dick has visited the site of a house fire that killed an elderly mother and her son, saying he knew the woman well.
The woman in her 80s and the man in his 60s died in the blaze south of Brisbane on Sunday night.
Emergency services found the suburban residence at Woodridge engulfed in flames when they arrived about 6pm.
Woodridge MP Mr Dick paid tribute to the elderly woman, leaving flowers at the home after arriving on Monday morning.
"She's a wonderful person, she had become very unwell in her later years," he told reporters.
"She'd been very helpful to me as a local member of parliament. She'd been very supportive of me personally."
Mr Dick described the tragedy as a "terrible blow for the community".
"You had a son caring for his mother and that they would both lose their lives in these terrible circumstances," he said.
Police are investigating the cause of the fire and are asking anyone with information to contact them.
