The Low Head foghorn building will be given new life as it receives its first touch-up in 13 years.

Low Head Pilot Station Support Group spokeswoman Jenny McClelland said the refurbishment would not only keep pests out, but provide a more sightly attraction for the growing string of visitors.

``On a Sunday, there could be between 40 and 50 people up there waiting for it to sound, it only runs for 15 minutes once a week,'' Mrs McClelland said.

``It's become amazingly popular by word-of-mouth.''

The 84-year-old foghorn is one of the biggest diaphones ever made, and one of two operational ``G-type'' foghorns in the world.

Community fund chairwoman Lynn Mason said the site was a valuable addition to the state's tourism portfolio.

``For this reason, the site's restoration is important for ensuring its machinery is properly preserved and this piece of maritime and social heritage is not lost,'' Ms Mason said.

The upgrade includes removal of the building's asbestos roof, restoration of its cladding and replacement of its walls, eaves, facia and gutter.
