Queensland's police officers and courtrooms will need to be trained to understand coercive control before it can be outlawed, the attorney general says.
Shannon Fentiman has announced that the state will criminalise behaviour including isolating partners from friends, dictating where they're allowed to go or controlling their finances.
Yet it won't be easy. Coercive control, unlike physical violence, is incredibly hard to prove.
The evidence is found almost entirely in witness statements from victims, their families and first responders.
Only a few other jurisdictions like England and Wales, Scotland and Tasmania have such laws.
Ms Fentiman says the success of legislation in those places has depended on people understanding coercive control and being able to identify it.
She says police, first responders and the courts will all have to be trained before the laws can be introduced to Queensland.
"I would hate for us to be introducing an offence of coercive control without having embarked on that training because, as I said, the success that we've seen overseas has been dependent on widespread, sustained training on the implementation," Ms Fentiman told AAP.
Opposition spokeswoman for women Ros Bates, who's a domestic violence survivor, supports the criminalisation of coercive control.
"When I was a kid, all I thought of was the physical violence ... the black eyes, the broken ribs and broken noses and all those sorts of things," she told AAP.
"That's what I thought was domestic violence.
"But now as an adult when I look back at what my mother's life is like, I now know that she was definitely a victim of coercive controlling behaviour."
However Ms Bates urged the government consider making coercive control part of a broader domestic violence offence to protect other family members like children and the elderly.
She said a broader domestic violence offence could cover physical violence, strangulation, coercive control, financial control and sexual violence.
"It will be very difficult as standalone offence to prosecute (coercive control) because the onus of proof is on the victim to provide the evidence," Ms Bates said.
Ms Fentiman is open to broadening the law after consultation with victims, advocates, first responders and legal experts.
However she says the new offence will be aimed at protecting women primarily.
The attorney-general added that coervice control was often a predictive factor in partner homicides.
"We'll keep an open mind about that but really we know it's a tool that perpetrators use against women in domestic violence situations," Ms Fentiman said.
"If we can actually intervene earlier when this power and control, this coercive control, is happening in domestic relationships then we can hopefully save women's lives."
