Gymea Bay infrastructure, key developments and investment opportunities
Gymea Bay: Stage 1 of the Gymea Bay Baths Reserve access upgrade is underway. Sutherland Shire Council started site works in May 2026 with practical completion expected in early 2027. The $4 million project delivers new stairs between Ellesmere Road and the foreshore, car-park improvements and reconstruction of the shared service road, bush regeneration and landscaping, localised drainage works, improvements to the concrete pool deck and removal of an unused storage shed; the reserve will be closed while construction is carried out.
