Dutch dredging operator Boskalis received Australian approval to extract up to 70 million m³ of sand from Cambridge Gulf in the Kimberley, with the material likely shipped to Southeast Asia for coastal protection or land development. Environmental group Environs Kimberley opposes the project, warning of harm to flatback turtle nesting sites (including Cape Domett, a rookery for 3,250 animals), humpback dolphins, snubfin dolphins, freshwater sawfish, and the northern river shark. A licence condition prohibits mining during peak flatback nesting season (August–September), though the Australian Marine Conservation Society notes evidence of year‑round nesting. Boskalis ruled out alternative offshore sites—Joseph Bonaparte Gulf, King Shoals, and Medusa Banks—because they lie inside marine parks or close to the Cape Domett turtle beach, and says its environmental assessments find no significant residual impacts.
