HRH the Duke of Gloucester officially opened the Captain Cook Graving Dock at Garden Island, Sydney. A ribbon suspended across the dock entrance was cut by HMAS LACHLAN, (frigate). The building of the dock was the largest engineering project undertaken in Australia up to that time. At the peak of its activity 4000 men were employed, 24 hours a day, on the project. The dock was designed to accommodate the largest warships afloat, and the super liners QUEEN MARY and QUEEN ELIZABETH.
