The restoration works involve repairing structural corrosion and repainting the lighthouse.
The works started in April this year and are due to be completed by mid-August, weather permitting.
Charles Point Lighthouse is the oldest lighthouse in the Northern Territory and became operational on 1 February, 1893.
The wrought and cast iron lighthouse is 32 metres high and its light can be seen from 17 nautical miles away. The lighthouse has survived a number of cyclones that have swept through Darwin.
The lighthouse was automated in 1933 and converted to solar power in 1994.
The lighthouse now also houses Automatic Identification System (AIS) equipment which enables the tracking of vessels in the surrounding waters.
AMSA’s Chief Executive Officer Graham Peachey said the restoration works were essential to maintain the structure to meet current operational requirements and to preserve the structure for future generations.
“The Charles Point Lighthouse is an important part of the Northern Territory’s history. The elements have taken their toll on the lighthouse over the years but these works will restore it to its former glory,” Mr Peachey said.
AMSA oversees a network of more than 500 visual and electronic aids to navigation across 400 sites throughout Australia. These aids to navigation include lighthouses, beacons and buoys and provide ships with the ability to navigate safely around Australia’s coastline and to and from ports.
