AUS - Collaroy sea wall: Work should stop immediately, objectors say

IT might be being billed as the multimillion-dollar solution to coastal erosion, but some residents say construction of a giant sea wall in Collaroy and Narrabeen should be stopped immediately.

The wall is being constructed to protect homes and utilities from large swells and storms, but Surfrider Foundation Northern Beaches president Brendan Donohoe said it could signal the end of the beach.

"We love the beach and the beach won't exist if they continue with this wall," he said. "When [big swells] hit a vertical face there's only one way for the energy to go and the sand will get sucked straight out.

"There will be two blocks of unwalkable beach after a big surf event, because the sand will get sucked out. Absolutely it'll present a danger to people walking along that section of the beach after a storm.

"We want an immediate moratorium on any extension of the wall."

Northern Beaches Council has already approved eight development applications for 'coastal protection works' that feature a sea wall. This represents 32 of the 49 land parcels requiring coastal protection.

The latest DA, which will protect five properties in the block between Clarke and Mactier streets, attracted more than 130 submissions from the public.
