Deputy Commissioner Steve Gollschewski has rejected demands for an independent investigation into police dealings with mother-of-three Kelly Wilkinson before she died in a ball of fire in her own backyard on Tuesday.

The 27-year-old was the third Queensland woman to die after allegedly being set on fire by abusive partners in the space of 12 months. In all three cases, the women had sought the protection of police before they were killed.

Justice campaigners are outraged after police announced an internal review into what contact they had with Ms Wilkinson in the lead-up to her death, and have demanded an independent investigation.

But Mr Gollschewski said the public would get that from the coronial investigation that's now underway.

He said he was sure the coroner would delve deeply into a police officer's decision to free Ms Wilkinson's estranged husband Brian Earl Johnston on bail not long before she was killed.

Johnston is facing murder and other charges, including breaching a domestic violence order. He remains in hospital where he's being treated for burns.

Not long before Ms Wilkinson was killed he was given police bail - without the oversight of a court - on other serious criminal charges, Mr Gollschewski told reporters on Friday.

"The appropriateness of that will be something that can sit within the coronial (investigation)," he said. "And we will certainly look at it as well."

He said Justice Margaret McMurdo also had scope to examine the bail issue as part of a wide-ranging review of women's experiences in the criminal justice system, aimed at improving domestic violence responses.

Ms Wilkinson's devastated father and sisters have accused police of failing to prevent an entirely preventable death, and three young children will grow up without their mum because of that.

They allege she endured years of controlling behaviour and left her husband when they were living in the US but he followed her back to the Gold Coast.

Danielle Carroll told of the family's frustration after driving her sister to see police "almost daily" and it's been claimed that after the protection order was in place against Johnston, Ms Wilkinson was told to "give him space".

Police have acknowledged she first reached out for help in late March and was given assistance then, that she attended a police station twice, and even asked domestic violence support workers to engage with police on her behalf.

Police Minister Mark Ryan said if any laws needed to change they would and said Johnston could have been ordered to wear a GPS tracking device if his bail had been considered by a court.

He said frontline services and domestic violence prevention programs had been significantly boosted since the death of Hannah Clarke and her children, and much work was being done to improve responses.

The Clarke family was ambushed and set on fire by Hannah's estranged husband on their way to school 12 months ago, and after she'd gone to police about her safety. He also died.

Just two months ago Doreen Langham perished in a fire police believe was lit by her estranged partner. She had recently moved into a secure gated community because she was so scared.

She'd also been in regular contact with police but despite that her final call for help was classified as non-urgent by a triple-zero operator. Her ex-partner perished alongside her.

"I know people want answers now but that work needs to be done and I need to let that work be done," the minister told reporters on Friday.

Justice McMurdo is due to report back to the government in October about how to criminalise coercive control with legislation to follow. She'll report on women's experiences in the criminal justice system by March next year.
