CEO of Liberty Domestic and Family Violence Specialist Services Kelly Lamb said domestic violence continues to be a "real issue in the community".

Referrals for the support service have increased by almost 30 per cent over the past year.

"Last financial year Liberty supported 865 women and children experiencing domestic violence," Mrs Lamb said.

"During October we received referrals for 52 women and 65 children - that's half our funding quota in one month alone.

"On one hand it is positive that women are reaching out for help, but on the other hand, it is shocking that so many women are experiencing violence right here in our community."

Mrs Lamb said the service is always in need of donations that might help people escaping domestic violence.

"It is lovely to be able to give them a package of personal items, nice clothing, some vouchers that they can get to access services and purchased goods," she said.

"Our community is very generous in that regard."

Mrs Lamb said Christmas can be "pressure point" when it comes to domestic violence.

"We find during Christmas time our women and children are more likely to want to stay at home and have a happy Christmas with their partners and obviously that is absolutely their choice and it is about keeping themselves safe."

Director of External Engagement at Charles Sturt University Kate Wood-Foye said the university was pleased to sponsor the event with a Health and Wellbeing grant.

"Our staff and students will come together to walk against violence, supporting the cause with the provision of paramedic services and water station crew," she said.

"We all have a role to play in creating a safe and vibrant community - the coastal walk is an inclusive experience encouraging community to unite, raise awareness and take a stand against family and domestic violence."

Mayor Peta Pinson said Port Macquarie-Hastings Council recognises the event as important for the community.

"We provide sponsorship because recognise it is such an important cause and Liberty do such an amazing job of providing awareness and helping not just women but men in the area," she said.

Participants can do the full 11km starting at Lighthouse Beach at 8.00am, 3km starting at Flynns Beach at 9.00am, or 2km starting at Town Beach at 9.30am. Free buses will run from Westport Park to Lighthouse and Flynns at the start of the walk.
