Located in Kamay Botany Bay National Park at Kurnell, Sydney, NSW, the boardwalk forms part of the National Park’s Stage 1 Master Plan works for NSW National Parks & Wildlife Service. The pathway follows a curved coastal alignment, connecting visitors to a dedicated whale viewing platform while integrating with the surrounding natural landscape.

View Full Case StudyThe project required an engineered FRP boardwalk system capable of following a complex curved alignment through a sensitive coastal environment. Varying ground conditions, exposed rock, marine corrosion and connections to stainless-steel viewing infrastructure required careful structural detailing and coordination.
Complex curved alignment
Individually detailed FRP framing, mini-mesh decking and curved kick rails were developed to follow the winding pathway while maintaining structural support and consistent pedestrian access.
Variable ground conditions
Adaptable foundation arrangements incorporated FRP posts embedded into natural ground or rock core holes, alongside timber sleeper supports for low-clearance sections.
Harsh coastal exposure
Corrosion-resistant FRP structural components and UV-stabilised mini-mesh decking were specified to provide long-term durability and reduced maintenance in the exposed marine environment.
Stainless-steel integration
The FRP boardwalk system was coordinated with 316/316L stainless-steel framing, stairs and balustrades around the whale viewing platform, incorporating detailed structural connections and proprietary grating fixings.
Safe pedestrian surfaces
Slip-resistant, 38 mm FRP mini-mesh grating was specified to provide a durable walking surface suitable for public use, with structural loading requirements appropriate for National Park visitor infrastructure.
