Ms Stevenson said the Warilla-based centre was one of 21 women's health centres in the state which would benefit from this week's announcement by Sophie Cotsis, the opposition spokeswoman for the status of women.

Ms Cotsis said a Labor government would guarantee the NSW government's current annual funding of $8.7 million for the centres, over the next five years.

An extra $1 million would go to the centres to expand their counselling and support services for victims of domestic violence and sexual assault.

Ms Stevenson said: "We have been facing funding uncertainty for some time now, with the current state government only committing to funding these centres through to June 2016.

"So we welcome this commitment by Labor and we're asking the Coalition to match it. This funding is critical as these centres provide essential health services to women, particularly those who are marginalised, in a safe women's-only space."

Ms Stevenson said the Warilla centre, which had been operating for 30 years, supported women across the Illawarra and Shoalhaven with a range of medical services and health and wellbeing programs.

She said the centre had staff with the expertise to work with vulnerable women experiencing domestic violence, mental illness, sexual abuse, unwanted pregnancies and other issues.

"We particularly welcome the additional funding for counselling and support services.

"Here in the Illawarra there's a very high demand on our counsellors as we are seeing increased levels of domestic violence and mental health issues such as anxiety and depression."
