Senator CONROY (Victoria—Deputy Leader of the Opposition in the Senate) (14:16): Mr President, I ask a supplementary question. Is the minister aware of concerns that the Japanese Soryu class submarine has a reserve buoyancy that is much greater than comparable submarines, which indicates that it is not designed to meet Australia's unique strategic needs for range, endurance and capability? Why is the minister planning to impose submarines that do not meet our requirements on the Australian Defence Force?
