Not entirely. What was in place at Osborne was the ship lift, a small number of construction buildings and both the ASC HQ and the AWD Systems Centre, used by the CoA and some contractors. From memory the whole thing, from a brown fields site, cost about $600m in 2007 dollars, split between the CoA and the State government. The expansion for Hunter added the two very large assembly halls (complete with robotics), a much larger paint shop, and a large number of miscellaneous facilities, including warehousing, accomodation for NCB, and the new HMAS Encounter facilities. It also built the new systems grooming centre at St Kilda. It was a very major expansion.
