Certainly the presentation of the budget, the estimates, and the approprials in advance of the financial year is a good idea. Certainly the way in which all government expenditure has been covered in the estimates and opened up for examination was a big change, and it's a change that came about by evolution, basically.
Those were the principal major changes that greatly improved the process. The introduction of the supplementary estimates hearings was a big improvement. They are the major changes. As I said, they came about as a result of the Senate and governments reacting to the process as it evolved.
I don't think you can take the partisanship and the politics out of this process. There will always be partisanship in the process. People will always be inclined to concentrate on controversial things and to probe those more thoroughly. But that's all part of accountability.
