This degaussing range, found at Steele Point, was constructed in 1960 and is still operated by the Royal Australian Navy today. Degaussing is the process of removing (or at least reducing) a magnetic field. This degaussing range services four areas in the harbour (about 500m from the building), where metal ships passing over will be automatically de-magnetised. Why? Mostly to prevent the triggering of seabed mines.
