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)
