The Charles Point Lighthouse situated on the Cox Peninsula, Northern Territory, was constructed in 1893 to mark the western approaches to Darwin. The lighthouse consists of a central riveted steel cylinder supported by an external canted lattice framework. The lighthouse structure was last repainted in 1999, and the lantern room in 2009 since this time touch up painting has been undertaken during regular maintenance activities. The paint system is now in a condition where it is not maintainable, a recent inspection identified signs of localized pitting corrosion, fading and general failure of the coating system.
