A woman is fighting for her life after she was shot through the passenger seat of a car.
The 33-year-old went to a Trees Rd home in Tallebudgera, on the southern end of the Gold Coast, around midday on Wednesday when she was shot in the back.
Police say she had been sitting in the passenger seat of a car when the shooting occurred. Detectives suspect the gunshot came from inside the vehicle and went through the seat.
The woman was rushed to the Gold Coast University Hospital with a life-threatening injury.
"We don't know at this point in time whether she'll survive," Detective Inspector Mark Mooney told reporters at the scene on Wednesday.
A homicide investigation has been launched given the severity of the victim's injuries.
Det Mooney said a person at the home had been moving out and the woman had arrived with a group to help.
He said a number of people had arrived throughout the day to collect free items advertised on Facebook Marketplace.
"At this point in time we don't know who the shooter is," Det Mooney said.
"We would suspect that they would know each other, but we're open to all scenarios."
Police have not yet found the firearm used.
Det Mooney said at least 10 people at the property had already given witness statements but police also want to speak with anyone who was there earlier in the day.
