Head west from the main settlement, between the salt lakes and through the bristling scrub towards the centre of the island, and you'll eventually start the steep climb up Oliver Hill. And it's not just another natural vantage point — Oliver Hill is one of the three locations on Wadjemup / Rottnest Island that showcases its wartime history.
Constructed in 1937 to defend Fremantle Port from potential enemy seaborne attacks, the battery of two 11-metre 9.2-inch naval guns at Oliver Hill is now a significant heritage icon. In fact, it's the only intact emplacement of its type left in Australia.
Sited to take advantage of panoramic views over the island, the guns were capable of firing an armour-piercing shell up to 28 km away, ensuring Fremantle's safety from enemy attack. Decommissioned in the 1960s, the guns and infrastructure still remain. And while the threat of seaborne attack is long gone, visitors can explore the site, and appreciate the lingering stories from yesteryear.
