Norah Head lighthouse back in full operation
26 July 2013
The Norah Head lighthouse is back in full operation.
A Roads and Maritime Services (RMS) spokesperson said in late May a temporary light was installed on the balcony of the lighthouse to provide safe navigation for mariners while investigations were carried out on an operational fault.
“The lens of the lighthouse light weighs five tonnes and rotates in a contained bath of mercury. It is one of only two of its kind in Australia and therefore the repair required expert advice,” the spokesperson said.
“Roads and Maritime Services (RMS ) retained a specialist lighthouse expert from Brisbane to look into the problem and carry out repairs.
“The lens turntable was tested and modifications made to its operation while around eight litres of mercury was strained to remove dust, dirt and lint.
“In mid July the light was turned back on and testing has been carried out since then to ensure it is operating to the required high standard.
“RMS is satisfied the historic lighthouse is back to its required operation,” the spokesperson said.
The cost of the work to repair the light was about $16,500.
