Oliver Hill is located close to the centre of Rottnest Island and features military remnants from World War II. Explore this nationally significant defence heritage site with the Rottnest Island Voluntary Guides.
Meet guides along the way and explore at your leisure one of the restored World War II 9.2-inch guns, the Ghost Engine interactive exhibit and a maze of underground tunnels. Discover why they were installed on Rottnest and how they operated.
