Increased funding for the NDIS - $13.2 billion over the next four years - will spur a public discussion on sustainability of the Scheme. Tonight’s Federal Budget forecasts that the NDIS will cost almost $32 billion in 2024-25, expenditure that is comparable to the cost of Medicare.

This year it is estimated that $23.2 billion will be spent on supports for NDIS participants, rising to $28.3 billion in 2022-23; $29.4 billion in 2023-24; and $31.9 billion in 2024-25.
