A comprehensive marine science program has been successfully completed, bolstering the Cook Labor Government’s efforts to enhance infrastructure while safeguarding the environment. The $13.5 million Westport Marine Science Program, a collaboration spearheaded by the independent Western Australian Marine Science Institution (WAMSI), has provided valuable insights to inform the planning of a new container port in Kwinana.
Key Findings Presented at Symposium
Today, key findings from the Westport Marine Science Program were unveiled at a symposium held during the Biodiversity Conference 2025. The program involved the work of 150 independent researchers across more than 30 projects, focusing on nine critical themes. Notably, the program has improved understanding of seagrass restoration and the overall ecology of Cockburn Sound.
One significant outcome resulted in the decision to relocate the port’s position one kilometre south to protect vital seagrass beds. Additionally, the project’s design now includes an open breakwater aimed at minimizing disruption to ocean currents that are essential for snapper spawning. These adjustments reflect the program’s commitment to integrating ecological considerations into infrastructure development.
Long-Term Environmental Impact and Future Plans
The findings from the WAMSI program are instrumental in developing a holistic ecosystem model that predicts environmental impacts and optimizes restoration efforts. This model will guide construction and management methodologies while evaluating marine restoration activities, including a major seagrass restoration initiative designed to support the long-term health of Cockburn Sound.
The insights gained will also contribute to Westport’s environmental impact assessment and approvals process, which will be subjected to public review. Furthermore, the program’s outputs will aid in formulating cumulative impact management strategies for activities planned throughout the State’s premier strategic industrial area adjoining Cockburn Sound.
In addition to its primary objectives, the Westport Marine Science Program is facilitating the planning of innovative projects aimed at enhancing environmental resilience. Recently funded initiatives include artificial reefs and community-driven seagrass restoration programs.
As noted by Transport Minister Rita Saffioti, “Our government is focused on delivering high-quality infrastructure that secures the economic future of our State. By investing in science early, well ahead of the Westport business case, we’ve been able to make informed decisions that avoid and minimize environmental impacts.”
She emphasized the importance of the program, stating, “This program demonstrates how science can shape better planning outcomes for critical infrastructure that will support our economy for the next century.”
The final reports generated through the Westport Marine Science Program will be published on the WAMSI website after undergoing a rigorous peer review process. The remaining reports are expected to be accessible to the public prior to the Environmental Protection Authority (EPA) releasing Westport’s environmental review document for public comment, anticipated in 2026. Interested parties can view the published reports at www.wamsi.org.au/projects/cockburn-sound.
Minister Saffioti concluded by expressing gratitude to the scientists and researchers involved, stating, “Their work has advanced marine science in WA and will continue to guide us as we plan for a resilient and environmentally responsible future.”
