Background
The owners of three residential beachfront properties at The Entrance North, NSW, have experienced persistent and significant coastal erosion, which was severely exacerbated by storms in 2020 and 2025. These events washed away parts of their rear yards, dune vegetation, and exposed buried construction waste, leaving the buildings vulnerable. Despite some emergency rock revetments, the erosion continued, creating a pressing need for a permanent solution.
Horton Coastal Engineering Pty Ltd, on behalf of the landowners, applied for development consent to build a 90-meter-long reinforced concrete seawall to protect the properties. The Central Coast Council opposed the application, arguing that the seawall would have an unacceptable adverse visual impact on the scenic quality of the coast and would set a negative precedent for future developments. After the application was deemed refused, the applicant appealed the decision to the Land and Environment Court of New South Wales.
The Court’s Holding
The Court granted development consent for the construction of the seawall, subject to conditions to be agreed upon by the parties. Commissioner Gray found that coastal protection works were essential to protect the properties from the “almost certain” risk of being undermined and catastrophically damaged by erosion, especially since no government-led retreat or compensation plan was available.
The central issue was the Council’s contention that the seawall’s visual impact was unacceptable. The Court acknowledged that a concrete wall introduces a man-made structure into a natural coastline. However, it found that the adverse visual impact would be primarily limited to times when the beach is in a fully eroded state. The Court concluded this impact was not “unacceptable,” reasoning that the seawall was designed to minimize its visual footprint, was anticipated by the area’s planning framework (including the newly certified Coastal Management Plan), and was a superior option to a rock revetment which would impede public access. The Court also dismissed the Council’s “precedent” argument, stating that the potential for future similar applications was not, on its own, a sufficient reason to refuse a necessary and well-designed project.
Key Takeaways
- In the face of severe coastal hazards, the protection of private property can be prioritized over concerns about the visual amenity of the coastline, especially when the proposed works are well-designed to minimize impact.
- The potential for a development to set a precedent for similar works is not, in itself, a sufficient ground for refusal, particularly when there is a clear and present risk to property and life.
- A development’s visual impact must be weighed against its necessity and the existing degraded state of the site. An engineered solution may be considered an improvement over an eroded, unsafe, and debris-strewn shoreline.
- The court will consider the objectives of all relevant planning instruments, including newly certified Coastal Management Plans, which can provide a strategic framework justifying specific types of coastal protection works.
Why It Matters
This decision provides important guidance for coastal communities throughout Australia grappling with the tension between protecting private property and preserving the natural character of the coastline. It affirms that well-engineered coastal protection works, such as seawalls, can be approved even with some visual impact, provided they are a necessary response to significant risk, designed to minimize harm, and consistent with the broader strategic planning for the area.
The judgment signals to councils and landowners that a pragmatic approach is required. Where property is at risk and a managed retreat is not an option, courts may favor engineered solutions that provide certainty and safety, rather than refusing them on aesthetic grounds or fears of setting a precedent. This outcome underscores the critical role of Coastal Management Plans in setting the ground rules for future coastal development and adaptation strategies.
