The museum is located in the original building of the Hay War Memorial High School which was built in 1923 as both a high school and the town’s war memorial to honour those who served in World War I. It is managed by the Hay War Memorial High School. The collection preserves stories of Hay and District war service and the life of the school.
The museum is currently developing a digital project. The HWMHS Museum was chosen as a prototype for the NSW Office of Veterans’ Affairs Anzac Community Grant Scheme. The digital project aims to engage school students and young people with their Anzac heritage and promote greater understanding of this. One of the outcomes of the project will be a series of professionally produced video clips about individual Hay service personnel across the twentieth century. The designers are also providing the school with a template for the continued production of these clips. Another aspect of the project has been the development of a comprehensive photographic record of the many HWMHS ex-students who have joined the armed services, from World War II through to the present day.
