As I was saying, if we didn't have the scale of additional investment across the range of shipbuilding and submarine construction activities, there would be no need to consider how it is we ensure that sustainment can also be accommodated rationally, sensibly and effectively into the future. But, as a government, we are absolutely determined to ensure that there is enormous additional activity, as there will be at Osborne in South Australia, across shipbuilding and submarine building, and that we also deliver the capability our defence forces need, including effective sustainment into the future.
