WORK will start on Monday at Kingscliff Beach to "close the gap" between rock walls.

Boral Construction will start moving 6300 tonnes of rock to the exposed foreshore between the Cudgen Headland Surf Life Saving Club and the Kingscliff Beach Bowls Club.

The project to build the rock wall to prevent erosion will start as soon as the NSW Surf Life Saving Championships ends this weekend to be finished by Easter.

Tweed Shire Council Mayor Barry Longland said the council had committed to "close the gap".

"The reason why we had the extraordinary meeting on Monday was because we wanted the work to start as soon as possible," Cr Longland said.

"We want it finished by Easter when we are expecting high tides.

"There will also be a lot of holidaymakers around."

Cr Longland said high tides at Kingscliff made the council nervous.

"It is always a moment of anxiety," he said.

"Everyone holds their breath."

He said erosion has been a concern at Kings- cliff for 18 months.

The rock-wall project is costing the Tweed Coast Holiday Parks Reserve Trust $440,000.

The erosion has claimed metres of fore- shore in the past year.

Council was forced to move seven cabins at the Kingscliff Beach Holiday Park that were under threat of toppling into the ocean.

A terminal wall was built in front of the surf club and a sandbag barrier in front of the park to protect the land from further erosion.
