The Women's Legal Service Tasmania chief executive said she would instead like to see a change in attitude across the community so that not as many orders are needed.

The Council of Australian Governments said on Friday that it was determined to come to agreement on the scheme that would allow for Tasmanian police and courts to find out about domestic violence orders from interstate.

Tasmania, Queensland and New South Wales were chosen to trial the system with an update expected by the end of the year.

"We do need to have something like this put in place, a lot of people see significant issues when they move between states," Ms Fahey said.

"But what we really need is much more education and programs that shift the community's attitude about violence. We need to teach people not to assault each other and not to be verbally or emotionally abusive."

COAG has also agreed to spend $30 million on a campaign to prevent violence against women.

Minister for Women Jacquie Petrusma said yesterday she strongly supported the Prime Minister's domestic violence agenda.

"Across the nation, about one woman a week dies at the hands of a partner, or ex-partner - too often while she is trying to leave the relationship," Ms Petrusma said.

"The new scheme will remove the need to register domestic violence orders manually and streamline the process.

"This model will enable automatic recognition and enforcement of domestic violence orders across jurisdictions, providing increased protection for victims who may need to move interstate to escape perpetrators."
