A neighbour heard yelling just before an explosion and fire ripped through a Brisbane home, killing two women and a man.
Fire crews found the bodies of three adults after the blaze at the Everton Hills property about 5.30am on Tuesday. The ages of the dead have not been released.
Police Inspector Daniel Bragg said neighbours reported hearing yelling and an explosion, before an intense fire took hold.
"It was a loud explosion, quite significant, and the neighbour that heard that explosion contacted the police," he told reporters at the scene.
"I'm told that the fire could be seen from a fair distance away and it was the flames and the smoke that actually led people to the address."
He said one neighbour had told police that there was "some yelling beforehand".
"At this stage we do not know what happened here. A very thorough investigation will be conducted into this."
Detectives remain at the Pavonia Street property and say the deaths are being treated as suspicious.
Neighbouring houses were evacuated as a precaution.
Pavonia Street is currently closed to traffic. The fire is out, but wisps of smoke are still coming from the home's blackened windows.
