Two bodies have been found in the ruins of a woman’s house burnt to the ground in suspicious circumstances south of Brisbane.

The 49-year-old, who was recently granted a domestic violence order, and a 49-year-old man known to her are unaccounted for after the Browns Plains blaze.

The man’s silver ute was found in a nearby car park after Monday morning’s fire, which police believe was deliberately lit.

Autopsies will determine whether the bodies found late Monday night are those of the missing pair.

Acting Detective Inspector Daniel Cunningham said it could take fire investigators up to a week to prepare a report about the cause of the blaze.

He wouldn’t confirm where the man lived or reports neighbours heard the couple arguing in the days before the fire.

“I can’t comment specifically on this particular history but in any situation involving domestic and family violence, it’s always concerning to us always, always,” Detective Inspector Cunningham said.

He confirmed a temporary protection order was issued by Beenleigh Magistrates Court on February 9.

Police are calling for anyone with any information about the couple or the blaze to come forward.
