There are calls for CCTV cameras to be installed by the nationally significant grave of Sir Henry Parkes, after vandals smashed a seat next to the grave.
Faulconbridge resident Craig Turner was walking past the Father of Federation's grave on Thursday morning, October 3, when he discovered the damage and reported it to Blue Mountains Council and Blue Mountains Police.
"It's one of Australia's biggest national treasures," he said.
"I thought it would be in a federal trust, it's such an important monument.
"Every prime minister plants a tree at the Corridor of Oaks and visits the graveside. It's dumbfounding [that it's not protected]," Mr Turner said.
He wants CCTV cameras installed by the grave so it's protected and treasured, just like in the US with their monuments to past presidents.
Even younger Faulconbridge residents agree.
"I do think we should put in more cautions here - it's a monument to such an important man," Alex Young said.
"A camera somewhere and a sign, something that discouraging and you will be fined a tonne of money."
"A camera would be a deterrent," Jourdarn Borkowski said.
A nearby culvert, rubbish bin in Faulconbridge Cemetery and pylon holding up the walkway to Faulconbridge Station has also been tagged with graffiti.
"I report the graffiti on a regular basis as it occurs," Mr Turner said.
Ward two Labor councillor Romola Hollywood said it was distressing the historic area had again been vandalised.
"It is important that we work with the police to find ways to better protect this area. We should consider all options including CCTV cameras," she said.
"I will also seek advice on the status of the plan of management for the Corridor of Oaks and Sir Henry Parkes grave, as well as what funding may be available through state and federal heritage grants to improve and upgrade this important heritage area in Faulconbridge."
Her fellow ward two councillors agreed more needed to be done to protect the area.
"This site is of national importance and we must be preserving it. It is appalling that some people have disregard for our heritage," said Liberal Cr Chris Van der Kley.
"It is just so disappointing when this kind of senseless vandalism is carried out, particularly on important historical assets," said Greens Cr Brent Hoare.
"There are certainly some very impressive surveillance and vandalism prevention technologies on the market, clearly more needs to be done to consider where and how these could be deployed, and the costs involved."
A Blue Mountains Council spokeswoman said the graffiti would be removed on Friday, October 11 and the seat is expected to be repaired in the next week.
"Council does monitor the area regularly and is considering whether additional security measures are needed, to ensure the grave is protected," she said.
