The WA Greens have called for the Cook Government to disendorse the floating Kimberley Marine Support Base which started construction in September, citing a flawed business case and environmental impacts. WA Greens MLC Dr Brad Pettitt said the project rested on “very speculative” and “shaky ground” and that Ports Minister David Michael should urgently review the project before tax payers “foot the bill”. “When you have the existing Port of Broome relying on Government intervention to turn a profit, it is difficult to see the need for the increased capacity of the KMSB,” he said. “I am also deeply concerned that the business case for this development is predicated on proposed oil and gas developments in the region which frankly have no long-term future in a rapidly changing climate.” Dr Pettitt said although KMSB had said the project would have a low environmental footprint, the construction process would undoubtedly impact local marine life. “While the KMSB project is touted as environmentally benign there will be unavoidable impacts including the direct impacts of pile driving to the diverse coral community, increased shipping impacting on rare and threatened snubfin dolphins and the heightened risk of marine invasive species on the Ramsar-listed Nagulagun Roebuck Bay Marine Park.” Hitting back at Dr Pettitt’s claims, KMSB chief executive Andrew Natta said KMSB was privately funded and bore the full financial risk of the project. “KMSB has obtained all necessary environmental approvals and have committed to stringent marine monitoring protocols during construction and ongoing operations,” he said. “The final design eliminates the need for capital dredging and spoil disposal, thereby ensuring minimal impact on the seabed and marine life within the existing port area.” Mr Natta said KMSB did not just service the oil and gas industry and the support base had been designed as a common user facility that was not dependent on any single customer or market. “KMSB will serve a wide range of users at the Port of Broome, reducing truck movements from Perth, thus cutting costs and lowering carbon emissions,” he said. Mr Natta said the facility would also enhance resilience against road transport disruptions due to flooding. Once completed the Kimberley Marine Support Base is projected to draw in $55 million revenue by 2027 despite the existing Port of Broome bringing in just $23m this year including $2.5m in State Government subsidies. The 9900sqm floating wharf project is estimated to create 260 jobs during construction and more than 500 permanent jobs in Broome once in operation. Construction of the project is expected to run until early 2025 with WA company Total AMS appointed as the lead contractor.
