The 100-year-old pools are undergoing renovations which will repair a leak in the western sea wall, strengthen all walls, improve drainage from the shorter pool and upgrade the walkway, while maintaining the present height profiles of all walls.

The 16-week time frame is dependent on favourable weather, tidal and ocean conditions.

Wollongong City Council is encouraging swimmers to make use of alternative tidal rock pools at Coledale and Bulli during the closure.
