A Queensland MP has called for further protections for domestic violence victims after one of his constituents was sued by her former partner for telling her story.

Rob Pyne used a private member's statement in the early hours of Friday morning to highlight the case of Susan Prince, who performed in a social theatre piece based on the real stories of more than a dozen victims and perpetrators of domestic violence.

While promoting the play, which was partially funded by Arts Queensland and regional councils and toured across 17 regional Queensland towns including Mr Pyne's electorate of Cairns, Mr Pyne said Ms Prince commented in an interview that she "related to her character as she had an abusive husband".

"This man, whom Susan divorced in 1983, is now taking Ms Prince to District court for defamation," Mr Pyne said.
