There would be economists who would say that's not right, but I wouldn't agree. I'm a person who is happy with the idea of the local build. In past construction, for example, with what we call the Anzac frigates—because the New Zealanders were also involved—we were able to take down a notional 20% premium to zero by the time the final ship was constructed.
The key point there is it's now clear that as you build a number of vessels, you will get a learning curve and a saving against each of those new ships as they come forward. The aim should be to bring the premium down to zero, or as low as you can make it competitively.
