Burnt before we're open
The fire, which was believed to be deliberately lit, caused significant damage to the newly completed boardwalk running parallel to Riverside Drive at Nambucca Heads.
A volunteer from the Nambucca Valley Visitor Information Centre was walking her dog at approximately 6am when she saw a part of the boardwalk smouldering.
It was reported that residents used buckets of water to put out the fire.
The fire was lit at the base of a support post which was destroyed and serious damage also occurred to the main beams underneath the deck.
The boardwalk has only been open to the public for a number of weeks and was due to be officially opened in October.
Nambucca Shire Council general manager, Michael Coulter, said the damage bill is in excess of $3000.
"While the boardwalk is still usable, the damage is significant," Mr Coulter said.
"It's pretty depressing as well since the boardwalk has proven itself very popular with locals and visitors.
"You can never understand what motivates a person to carry out vandalism to a public asset which has been well received and well used."
Visitor Information Centre tourism coordinator, Maita Van Stockum, said the damage was 'a shame'.
"The boardwalk only opened weeks ago and it's beautiful, a big asset used by everybody in Nambucca," Ms Van Stockum said.
