Vanessa Keenan and Mackenna Powell will step into vacancies left by the resignations of Helen Mundy and Geraldine Rurenga from the management committee of the 40-year-old centre, which provides support for women experiencing issues including domestic violence, sexual assault, homelessness, poverty, relationship breakdown, isolation and mental health.

Acting president of the health centre Genevieve Fleming said Ms Keenan and Ms Powell were "ideally positioned to contribute to the continued growth and enhancement of the Centre for the benefit of women in the community".

"Vanessa and Mackenna are both strong advocates for women's rights and gender equality," she said.

"They also have extensive experience and education in governance matters, which will ensure that the centre continues to exceed the expectations and requirements of both its funding providers and local women in our community."

Ms Keenan, a Wagga councillor who has more 18 years of experience working in strategic planning, policy development, community engagement, and communications across regional NSW, said she believed being a part of the management committee would allow her to "give back to the community".

"We are seeing in Wagga the domestic violence rates are nearly 30 per cent higher than the state average and that's something that is really quite troubling," she said.

"We're also seeing that even though abortion has been decriminalised in NSW, it's doesn't necessarily mean we see a change of services here in Wagga, with access to reproductive health, contraceptive pills and abortions as well.

"We still have a long way to go."

Ms Powell, who works in insurance and is a director of the Wagga Business Chamber, said "we do still need to continue to need this service in our community".

"In the 12 months to July, we have had over 400 cases of domestic violence right here in Wagga," she said.

"In the 40 years the health centre has been open, unfortunately we have not see a decline in the statistics of domestic violence."
