This is Minister Shorten's area. In the work that I am doing in forensically looking at all of the costs through the budget, I know he is applying himself to make sure that every dollar spent in the NDIS is going where it needs to go. He has been leading that work. I know that you will have been following that, Senator Steele-John. In terms of additional investments, or what flows through in the budget, you will have to wait and see. But I can assure you it hasn't been the focus of my attention in terms of looking at areas where we can make sensible savings in the October budget. I would also point out that the way that it is written into the budget, or factored into the budget, where there are ups and downs it's through parameter variations and that's informed by an actuarial assessment.
