Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:03): Mr President, I ask a supplementary question. I refer to evidence to the Senate by another submarine expert, Commodore Paul Greenfield. He said: If government wants to avoid a capability gap, the timing of delivery and the rate of delivery can be arranged so that the new submarines can be introduced in lockstep with the Collins submarines as they are withdrawn from service. Why is the government ignoring the experts on Australia's Future Submarine project?
