A motion by Cr Paul Le Mottee backed by Cr John Nell received unanimous support last Tuesday night requesting that council apply for a government grant.

The work is expected to cost between $160,000-$180,000.

Cr Nell said there was an urgency to commence repair work.

"We have lost up to 7m of the bank from the old timber wall and if the erosion continues at this rate we could be faced with an [environmental] disaster," he said.

Resident Peter Walsh said that the loss of sand had been occurring at an alarming rate, exposing the unseen coffee rock and the roots of two paperback trees, which are becoming dangerously undermined.

"If these trees are lost it is likely the main sewer line running behind the trees will be fractured," he said.

Neighbour Brett Flack said that trouble began following the April 2015 super storm, which had left the timber seawall severely damaged and exposing public to significant risk of floating debris.

"At the time council decided to spend $18,569 on remedial works as funding was unavailable," he said.

"The foreshore was re-turfed but within a week a king tide wiped out most of the newly laid turf. Residents propagated and planted 160 pigface plants to promote buffalo regrowth.

"While the western half thrives, the eastern half continues to erode."
