Mr ROBERT (Fadden—Minister for the National Disability Insurance Scheme and Minister for Government Services) (14:05): Let me thank the shadow minister for his question. As he knows, today in the final budget update, the actual number for the NDIS was a spend of $8.5 billion. The great thing to remember about the NDIS is that, if we look at the cost per participant, in the 2018-19 budget an expenditure was estimated of $46,400 per participant; the actual amount spent per participant on supports was $46,800—a $400 increase. Not a single participant has seen a decrease. The way we explain the underspend— Ms Butler interjecting— Mr ROBERT: I'm getting to the underspend. The underspend figure of $4.6 billion can be explained as follows. When the bilateral estimates were put together, the bilateral estimates said there would be 302,172 Australians. Those bilateral estimates— Honourable members interjecting— The SPEAKER: I'm just going to say to the member for Rankin and the Treasurer, please cease interjecting. I'm expected to hear the answer. The minister is not answering the question quietly, can I say, and it's still very difficult to hear. Mr ROBERT: It's very noisy, Mr Speaker. The bilateral estimates had 302,000 expected citizens, but, once the data arrived from the states and territories, only 199,000 citizens could be found; 100,000 people, from data provided by the states and territories, have not been able to be found or have been double-counted or, frankly, the data is wrong—100,000! However, on top of that, the bilateral estimates said that 69,195 new participants would come through. In actuality, 117,000 new participants have sought access. A 169 per cent increase in new participants has come through. And how is it that we've been able to fund this demand-driven scheme? Ms Butler interjecting— The SPEAKER: The member for Griffith is warned. Mr ROBERT: It's an uncapped, demand-driven scheme. The only way we've been able to fund it, not last year, not just this year, but for every year going forward—$17.8 billion this year, growing to $25 billion in 2022-23—is because this government, led by this Treasurer, has actually balanced the budget. Today's announcement was about balancing the budget for the first time in a long time—11 years, precipitated by those opposite. The budget is balanced this year and next year and the following years going forward. This government will not be lectured by those opposite when it comes to fiscal discipline and how we fund services. Mr Perrett interjecting— The SPEAKER: The member for Moreton will cease interjecting. Could he refer back to everything I've said during the week. Mr Perrett interjecting— The SPEAKER: No, don't talk! That's the point. I've been warning you all week. You know what will happen.
