Actually, all three—the United Kingdom, Australia, and New Zealand—did comprehensive defence policy reviews in about the year and a half preceding the launch of ours. They were all very generous with their time in helping us, and we learned some important lessons from each of them.
The thing we learned from the Australians that was particularly useful was the necessity to have a credible third party do outside verification of all of our costings, because we were looking at an extremely long period of time, 20 years, and we knew there would be a lot of expenditures over that time. We knew we would need to have outside experts, so we did. In fact, when we talked to the Australians about it, they said this is the accounting firm we used to do that process, and we recommend you use the same ones. When we talked to that firm, they said they could not only do the same thing for us as they did for the Australians, but they could actually give us the same accountants, and so they gave us the same people to do a lot of the work on the program.
From the New Zealanders we learned a lot about the consultation process. In fact, if you look at our original consultation document, you will note there's a strong resemblance in format to the one the New Zealanders used to launch their process. They were the ones who told us a lot about how to run that exercise.
The United Kingdom was also extremely useful. Theirs was perhaps the broadest and most comprehensive exercise.
We did talk to the Americans as well, but their system traditionally has been much more different. They have a legislatively mandated quadrennial defence review. It's a different exercise, and of course the scale is just entirely different.
