Sex cannot be consensual if a partner does not give a verbal "yes", according to a New South Government awareness campaign.

The education campaign is part of the Government's sexual assault strategy, which is designed to prevent sexual assault and harassment.

It will also provide greater support to survivors of abuse and improve training for frontline staff.

One in five women and nearly one in 20 men have experienced sexual violence after the age of 15 years.

Minister for the Prevention of Domestic Violence and Sexual Assault, Pru Goward, said she wants the campaign to shift to cultural attitudes around what constitutes sexual assault and make it "second nature" to request verbal consent.

"A clear 'yes' is at the core of this strategy," Ms Goward said.

"We need to get that conversation in every university, every TAFE campus and every workplace."

Campaign material will be distributed at university campuses and residential colleges and will also roll out on social media.

"The campaign will identify the continuum of sexual harassment to sexual assault, and the role the bystander and community can play in identifying sexual offending and speaking out," the strategy states.

"The campaign will also highlight gender inequality as a driver of sexual assault and harassment."

Changes to school curriculums flagged

Ms Goward said the multi-pronged strategy, which has been developed with input from university students, frontline workers and non-government originations, is the first of its kind in NSW.

"The strategy recognises that individual characteristics such as gender, age, disability, ethnicity, sexuality and race can intersect and impact on a person's experience of violence, their ability to access services, seek justice and recover," she said.

Other measures in the strategy include priority housing for adult survivors of child sexual abuse, a review of the intersections between mental health and abuse and modifications to NSW school curriculums.

The Government will provide input to the NSW Education Standard Authority review of K–12 school syllabuses to ensure "inclusion of content related to the continuum of sexual violence and future teacher training".

Earlier this year, Attorney-General Mark Speakman ordered a review into the state's consent laws, following a Four Corners report into a sexual assault case involving Sydney man Luke Lazarus.

Mr Lazarus was accused if raping Saxon Mullins, 18, outside his father's Kings Cross night club in 2013.

He was found not guilty on appeal.

The case threw a spotlight on the legal and social ambiguity around sexual consent.
