The remains, recovered from the extensively damaged residence last night, are believed to be of a man and a woman, both aged 49, who have been missing since the blaze engulfed the home on Moyla Street.
Preliminary investigations indicate the fire was deliberately lit and a crime scene has been established.
Autopsies will be conducted to determine the identities of the deceased.
Police said the man and woman were previously in a relationship and a domestic violence order was issued by the Beenleigh Magistrates Court earlier this month.
Investigations are continuing into the circumstances of the fire, and the nature of their relationship.
Police said the 49-year-old woman resided in the unit, with property listings for the secure complex saying it had 24-hour video surveillance.
Footage obtained by Nine News appeared to show CCTV vision of a man in an orange shirt with khaki pants at a petrol station, then jumping a fence at the complex.
Premier Annastacia Palaszczuk today said she was awaiting the outcome of the police investigation.
“It’s an absolute tragedy,” Palaszczuk said.
“It’s unbelievable that this is happening in this day and age.”
Emergency services were called to the home around 4:00am Monday, when it took fire crews 30 minutes to contain the blaze.
Police are working to determine the events leading up to the fire and are appealing for anyone with information to come forward.
The incident came only days after the one-year anniversary of the domestic violence deaths of Hannah Clarke and her three children.
Speaking in State Parliament, the Minister for the Prevention of Domestic and Family Violence, Shannon Fentiman, said the anniversary was a “tragic reminder of the insidious nature of domestic and family violence.”
“And so too was the news overnight of the townhouse fire in Browns Plains, where two bodies were found with police confirming a domestic violence order had been issued,” she said.
“Any death from domestic and family violence is absolutely unacceptable and my deepest sympathies are with those affected by these tragic incidents.”Jump to next article
