At Old Bar Beach the powerful surf ripped sand out from beneath the walkway in front of the surf club, resulting in council boarding the area off to the public.

A council spokesperson said sand scraping work that was previously undertaken on the beach helped provide a buffer against the large waves, but reminded beachgoers to be mindful of the changed conditions.

The spokesperson said council had both short and long-term plans in place to respond to the erosion.

"Council plans to move sand on the beach to make these walkways more accessible, however, we will delay doing so until after Wednesday, where more large swells are predicted," they said.

"Council is currently developing a coastal management plan for Old Bar Beach and Manning Point. This plan outlines strategies and prioritises coastal management options for the region."
