NSW consent laws to be put before Law Reform Commission, and it's thanks to Saxon Mullins.

Sexual consent laws in NSW will be reviewed after the woman who accused a man of raping her in a Kings Cross lane when she was an 18-year-old virgin spoke publicly about her ordeal.

NSW Attorney-General Mark Speakman said on Tuesday he would refer the state’s consent laws to the Law Reform Commission.

Saxon Mullins, now 23, was anally raped in an alleyway behind a popular nightclub in Sydney’s party district in 2013 on her first night out in the big smoke.

She shared her story on Monday night on ABC’s Four Corners in the hope of provoking a discussion about consent.

Over a five-year period, Ms Saxon endured two trials and two appeals with Luke Lazarus eventually walking free.

After the first jury trial he spent 11 months in jail before his conviction for raping Ms Mullins was overturned on appeal in 2016.

He was later cleared following a judge-alone retrial.

The NSW Director of Public Prosecutions then lodged an appeal against the acquittal over the May 2013 incident.

In the second appeal last November, the Court of Criminal Appeal found that while the judge in the second trial erred, Mr Lazarus would not be retried with a judge saying it would be “oppressive” for him to have “the expense and worry” of another hearing.

Mr Speakman said sexual consent laws needed clarity.

“What this shows is that there is a real question about whether our law in NSW is clear enough, is certain enough, is fair enough,” Mr Speakman told ABC radio on Tuesday.

“That is why I have asked the Law Reform Commission to look at the whole question of consent in sexual assault trials.”

The trial heard Mr Lazarus met Ms Mullins on the dance floor where he told her he was part owner of the nightclub and offered to introduce her to the DJ in the VIP area.

Instead he led her into a back lane way and the pair kissed before, according to Ms Mullins, he forced her into the sex act.
