Emergency services were called to the Springfield Lakes property, west of Brisbane, about 8pm on Friday after reports the woman had collapsed.Â
When responders arrived, they found the 23-year-old unconscious and not breathing. Her two young children were at home at the time.
She died at the scene.
The woman's husband, 26, and his brother, 28, who both lived at the property, were taken into custody at the home.
Both were charged on Saturday with domestic violence-related murder..
The family was originally from Afghanistan and had only recently moved into the property, Detective Inspector Michael Manago said.
The two children are being cared for off site.
"... this is a terribly tragic event, especially given young children being in the home, and our thoughts go out to the victims, family and friends who are naturally impacted by what's transpired," Det Insp Manago said.
Forensic officers were still combing through the property more than 16 hours after the emergency call.
Police tape was placed around the home, while several investigators were focusing their attention on an outdoor area of the residence.
A Mercedes-Benz was also seized.
Police did not reveal what, if any, injuries were visible on the woman or how she was believed to have died.
The scene was nonetheless described as confronting for the paramedics and police who first attended the home.
"As you can imagine, any scene such as that, is quite a chaotic scene," Det Insp Manago said.
"They acted professionally and I just want to acknowledge the great work they did in attempting to revive that young victim," he said.
The two men are due to appear at Ipswich Magistrates Court on Monday.
