The ‘Ozone’ was a paddle steamer built in Scotland in 1885. It was sailed to Australia and was used to transport passengers between Melbourne and Geelong. The ship officially retired in 1918 and was sunk off Indented Head in 1925 to create a safe harbour on a coastline badly affected by windstorms. In 1992 the anchor of the ‘Ozone’ wreck was retrieved from the bay and in 1995 was placed on The Esplanade as a commemorative monument.
