Senator CONROY (Victoria—Deputy Leader of the Opposition in the Senate) (14:15): Mr President, I ask a supplementary question. Is the minister aware that these two submarine experts have also said, and I quote: … big compromises would have to be accepted if Australia is to buy Japanese without serious design modifications, incurring further time delays, high cost and risk. I ask again: what do the Prime Minister and the defence minister know about submarine capability that Rear Admiral Briggs and Commodore Roach do not? (Time expired)
