The proposal is for the dredging of 12 million cubic metres of sediments to widen and deepen the existing shipping channel into Princess Royal Harbour and to extend the shipping channel into King George Sound to allow access of cape-size vessels to the Port. Dredged material will be disposed offshore at a location in King George Sound.

A portion of the dredged material will be used for reclamation of up to 9 hectares of Princess Royal Harbour to construct a new berth (Berth 7).
