The World War One Memorial at Jilliby Cemetery honours men and women from the Wyong District who served during the Great War. Many soldiers who returned home after the war are buried here, making the cemetery a place of strong local and historical significance.

A Lone Pine tree has also been planted at the site. The tree was grown from a seedling taken from the original Lone Pine at Gallipoli, linking the memorial directly to one of the most significant battles of the war.

In 2019, a new memorial was unveiled at Jilliby Cemetery to recognise the service and sacrifice of local men and women who served in World War One.  The memorial was officially unveiled by Wyong RSL Sub-Branch President Alan Stanford and the Federal Member for Dobell, Emma McBride. Central Coast Mayor Jane Smith and Member for Wyong David Harris also spoke at the ceremony.

Wyong RSL Sub-Branch Vice-President Peter Niven said the Jilliby Valley was one of 1,701 recruitment centres in New South Wales and a key staging point on the Central Coast for those leaving to serve the British Empire. He noted that many people from the Wyong District did not return from the war and are buried overseas, while many who did return are now laid to rest at Jilliby Cemetery.

A special part of the unveiling ceremony was the planting of the Lone Pine tree. Mr Niven said the Sub-Branch was grateful to provide a fitting memorial to honour the volunteers who gave so much for the freedoms enjoyed today.

Among those attending the ceremony were Joanne Cullen and her father, Bill Dafter. Bill’s parents are buried at Jilliby Cemetery, and his father, Norman Dafter, was a World War One veteran who returned home after the war. Enlisting at the age of 21, Norman served in Egypt and France, where he was wounded and suffered trench foot. He was later treated in a repatriation hospital in England, where he met his future wife, Margaret, from Gloucestershire.

After the war, Norman and Margaret settled in Australia at The Entrance and raised ten children. Norman was one of the many returned servicemen the memorial was created to honour.

Funding for the memorial was provided to the Wyong RSL Sub-Branch through the ANZAC Centenary Grants Program.
