Replacement of the Nielsen Park seawall

The Department of Climate Change, Energy, the Environment and Water is pleased to announce that Cherrie Civil Engineering has been engaged to complete the replacement of the Nielsen Park seawall after an earlier works contract was terminated. As part of the engagement process, the department and independent experts undertook a detailed review and assessment of the construction methodology and program. This review was done to ensure the project can be completed as soon as possible and without compromising on safety or longevity of the seawall.

Cherrie Civil Engineering commenced off-site planning and preparations from April to May 2023 and commenced on site works in June 2023. The current construction program forecasts completion of the seawall's concrete bleachers and removal of the protective sheet pile wall no earlier than February 2024. Full completion, including promenade works and landscaping is forecast for June 2024. This is subject to adverse weather and any latent site conditions.

The unfortunate delays to this project have extended the closure beyond the original scope, and we understand this has impacted the local community and visitors. However, we are taking great care to ensure the best outcome for our community and the park's natural, cultural and historic values.

Shark Beach, including the water immediately in front of the beach, remains closed to visitors. For public safety, access to the beach, water and promenade cannot be provided. Visitors should follow safety and detour signage instructions while construction is underway. Please do not enter the fenced work areas.

The Sydney Restaurant Group are taking this opportunity to carry out renovations to the historic Nielsen Park Kiosk, the Halbert Pavilion and the Swimming and Life Saving Club. These venues will reopen to the public once the seawall works are completed in 2024.

Short-term accommodation bookings can still be made for Steele Point Cottage.

Replacement of the Nielsen Park seawall is a complex project. National Parks and Wildlife Service wishes to thank the community for their understanding and patience while this project is underway. Once completed, the new seawall and promenade works will improve accessibility and amenity at Shark Beach and protect Nielsen Park so that visitors can enjoy it for another 100 years.

The development application for the replacement of the Nielsen Park seawall was submitted on 30 June 2020 and advertised and notified in accordance with Section A2 – Advertising and Notification, of council's Woollahra Development Control Plan 2015 from 2 September to 1 October 2020.

The project was approved by the Sydney East Regional Planning Panel on 18 February 2021.

The Section 60 approval from Heritage NSW was received on 16 April 2021.

Stakeholders, visitors and nearby residents will be kept informed of this project as it develops. Updates will be available from this project webpage. You can also register to receive updates directly via the online form at the end of this page.

In accordance with NSW planning legislation, we have carried out a rigorous environmental assessment of the site with input from specialists in landscape architecture, archaeology, heritage, engineering and coastal management. The project is consistent with the Sydney Harbour National Park Plan of Management 2012 and the Nielsen Park Conservation Management Plan 2013.

The National Parks and Wildlife Service is committed to delivering this project whilst ensuring the natural and cultural values of the park are protected.

There will be unavoidable impacts to visitation during the construction phase in 2023 and 2024. In preparing the schedule of works, a balance between effects on visitor convenience, cost, and environmental impact of staging the works has been considered.

Please be aware of the following changes:

• The construction zone will include Shark Beach and the promenade from Greycliffe Avenue, which will be closed for the project's duration.
• The Nielsen kiosk and restaurant is closed. Renovations to this building are underway. The reopening date will be advised.
• Short term accommodation bookings at Gardener’s Cottage will be suspended for the duration of the project. Steele Point Cottage is available for bookings.
• Events in Nielsen Park will be suspended during the duration of the project.
• The toilets at the eastern end of the beach (near the Greycliffe Avenue entry) will be closed.
• The toilets located at the Steele Point end of the promenade, the Dressing Pavilion and the women's toilets off Bottle and Glass Road will remain open.
• The Hermitage walking track will remain open. Detours through Nielsen Park away from Shark Beach will be marked on site.
• Bottle and Glass Point, Shakespeare's Point, and most of Nielsen Park south of the promenade remain open.

Visitors and local residents can access a number of other beaches, picnic areas and swimming facilities in the vicinity of Shark Bay and Nielsen Park. This includes:

South

• Milk Beach (500m)
• Hermit Beach (1 km)
• Queens Beach (1 km)
• Rose Bay Beach (2kms)
• Murray Rose Pool, formally known as Redleaf is netted (5 kms)

East/North

• Parsley Bay Beach (2 kms)
• Kutti Beach (3 kms)
• Gibsons Beach (3 kms)
• Watsons Bay Baths (3.3 kms)
• Watsons Bay Beach (3.8 kms)
• Camp Cove Beach (4 kms)

During the demolition of the concrete seawall, asbestos was found in the fill under the concrete seawall. As the seawall was built c. 1930s, it is not unusual to find this type of material which had been used in construction projects since 1921. The site was immediately secured and an Environmental Hygienist attended. An Asbestos Management Plan was implemented and this hazardous material was removed in April 2022. This was undertaken by specialist teams with dust mitigation measures and air monitoring to ensure that fibres did not become airborne. All trucks leaving the site were sealed, and the material was disposed at a licensed off-site facility. Testing of the site has been undertaken to ensure all hazardous material has been removed. Monitoring will continue to ensure that any additional material is identified and safely removed.

The existing vehicle ramp at the east end of Shark Beach will be rebuilt as part of this project to allow access to the beach for park operations such as the annual removal of the shark net. Visitors will also be able to use this ramp for launching kayaks, paddleboards and the like.

A new pedestrian ramp will be constructed between this ramp and the toilets. This pedestrian ramp will provide compliant accessibility to the beach.

Additional stairs which are access compliant will also be installed along the length of the seawall.

Additional options such as handrails or pathways onto the beach have been considered. However, Shark Beach regularly experiences damaging storm surges. These storm surges can result in significant sand movement and undermine infrastructure. Installation of permanent infrastructure on the beach itself was therefore not considered feasible. We will continue to investigate and review accessibility improvements in the park.

The row of trees along the grassed area on the beach side of the promenade are located within the construction zone.

While it is regrettable to remove any trees, the extent of works includes complete demolition, excavation and reconstruction of this area. New, mature trees of the same species removed will be planted as part of this project. An additional 5 trees will be planted along the beach front.

The project team carefully considered the materiality and character of Shark Beach. The seawall itself will be approximately 0.5m higher at the promenade level, while the structure will extend deeper below the beach surface to reduce the risk of gaps resulting from the movement of sand during storm events. Additionally, the design of the new seawall will incorporate the following:

• modified bleachers profile with wave deflectors built in to manage storm events
• stairs, ramps and level changes will be made access compliant
• the landscape amenity will be improved (increased lawn areas and more shade trees).

No. Shark Beach will be a construction site with a break wall built on the beach and significant earthworks, piling rigs, concrete pumps and heavy vehicle movements in and around the site. For public safety, access to the beach and promenade cannot provided during the demolition and construction phase.

Public access to the beach and promenade will be reinstated as soon as it is safe to do so.

Staging the works was considered to allow access to the water for visitors. However, given the small site, the considerable set up and establishment works required and the limited availability of specialist contractors and equipment it was not a practical option. It is a quicker and more cost effective to do the works in one go. Extending the duration of the project by staging the works, will have a greater impact on visitors, businesses and neighbouring community.

Currently, there are no plans to upgrade the Dressing Pavilion building while the seawall replacement is underway.
