Replacement of the Nielsen Park seawall

National Parks and Wildlife Service is replacing the concrete seawall at Nielsen Park, part of the Sydney Harbour National Park.

Important

Replacement of the seawall has commenced.

Shark Beach and the promenade remain closed while the works are being carried out.

The Nielsen Park Kiosk is also currently closed for renovations.

The seawall at Nielsen Park has served visitors well for nearly 100 years. In July 2016, the seawall was badly damaged by large swells during storms. Some sections of the sandstone seawall along the western part of the beach were repaired, but the 160-metre concrete seawall has reached the end of its serviceable life.

National Parks and Wildlife Service (NPWS) has demolished the old seawall and will be constructing a new seawall more capable of withstanding adverse weather conditions and sea level rise, while improving accessibility to the beach. This once-in-a-lifetime project will conserve the sensitive natural, cultural and social environment, and heritage significance while improving the structure to meet visitor and operational needs.

Nielsen Park at Vaucluse was incorporated into Sydney Harbour National Park in 1975 and was listed on the NSW State Heritage Register in 2018 in recognition of its outstanding natural and cultural landscape, demonstrating a rich and diverse range of uses spanning from Aboriginal occupation to the present. As a sensitive site, unforeseen issues may arise during the construction phase. These issues will be managed appropriately under relevant legislation and regulations, and we will provide updates to the community via this webpage as they become available.

The replacement of the Nielsen Park seawall commenced in March 2022. After demolition commenced, asbestos was discovered beneath the wall in old fill. This hazardous material was safely captured and removed in April with monitoring complete, and clearance certificates obtained in May.

Sydney has received a record-breaking level of rainfall in 2022, which is expected to continue through to early 2023. In addition, the east-coast lows resulted in some impacts to the works site but were largely mitigated by the contractor, who was able to secure the site during the worst of this weather.

Regrettably, these issues have impacted the works program, and we are now expecting this project to be completed in April 2023. This is a highly complex and challenging project. We are taking great care to ensure this is carried out appropriately to ensure the best outcome for our community and the park's natural and cultural values.

Shark Beach, including the water immediately in front of the beach, remains closed to all visitors. For public safety, access to the beach, water and promenade cannot be provided.

The Nielsen (restaurant and kiosk) will be closed during this period, with renovations of the heritage building scheduled. No event bookings will be available for Nielsen Park, and the short-term accommodation (Gardeners Cottage and Steel Point Cottage) is closed while works are occurring.

The Nielsen Park seawall replacement is a major, complex project and National Parks and Wildlife Service thanks the community for understanding and patience while this project is underway.

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 2022 and 2023. 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 will close from 1 March. Renovations to this building will be undertaken during 2022. The reopening date will be advised.
  • Short term accommodation bookings at Gardener's Cottage and Steel Point Cottage will be suspended for the duration of the project.
  • 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.

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.
