North Cronulla beach and The Wall have been been severely impacted by this week's big seas, whipped up by a classic East Coast Low sitting just off the Sydney coast.
Pounding waves and big high tides have gouged out a huge amount of sand at the northern end of the beach and the base of the Prince Street seawall exposing rocks that locals said haven't been seen for decades - and dumped there after the Prince Street wall was built in the early 80's.
Other Bate Bay beaches do not appear to have suffered any further significant damage.
All Cronulla beaches and retaining walls took a battering from big swells and powerful winds from two East Coast Lows in the space of a fortnight in July and a another severe weather event between August 8-10.
Sutherland Shire Council advised at the time there was no evidence of damage to the Prince Street seawall.
However, the council said additional concreting would be carried out on the base of the structure to improve its resilience.
Following an assessment of damage to all the beaches, the council said repairs would be left to natural forces.
"Council will continue to take any measures warranted along Bate Bay, including restricting public access where necessary, preserving access routes for the Ocean Safety and Lifeguards Team and equipment, as well as providing public warning advice and clearing hazardous items as necessary," a spokeswoman said.
"In addition to these works, council expects calmer conditions usually experienced at this time of year to see sand gradually replenished."
