Oak Hill is an area of special significance for the Ngunnawal people of Yass. Archaeological and historical evidence shows a long association with Aboriginal people before and after European settlement. Camps on the former Aboriginal reserve were occupied by from the late 1880s to the 1950s. The presence of burial sites at Oak Hill underlines the spiritual nature of the site.
The new signage structure is designed from a robust elemental language of large sectioned timber posts and galvanized steel, which frame the signage panels. The signage includes photographs of artefacts found at the site, plans and descriptions of the site huts that were used as dwellings at the time, a timeline of major events, and descriptions of the three Aboriginal scarred trees that once grew close to the area.
