As was outlined, there has been an awful lot of very detailed review in terms of science. Our overall number of collaborator arrangements of all sorts came out at around $23 million. Some of those would not have continued; some of them have really nothing to do with science. So the overall number was around $23 million.
In terms of science and shared science, we assessed the requirement in the areas that Bill outlined to be in the order of $10 million to $12 million annually. So obviously after the decision in June and a fair amount of analysis, this became part of the budget process, which ultimately led to that unfolding in the budget.
As has also been outlined, this is a dynamic area. Individual decisions had to be taken. We took individual decisions following the decision, within the best framework of legal advice and so on, while we put together a policy framework. As has been indicated, that policy framework is now going into consultation with industry, and at the end of all of this, after further consultation with industry, we'll come back to the minister with additional advice for the revisions that may be required.
