Barnett told The West Australian newspaper that a potential blowout of the NDIS was “way beyond what’s being talked about”.

We know enough to know the final cost has blown out and that’s because of people using the service, the cost of delivery. We don’t know exactly but it’s not marginal,” Barnett said.

But a spokesperson for Federal Social Services Minister Christian Porter said there was “absolutely no budget blowout”.

“In fact, expert analysis based on the full range of data from trial sites shows the scheme is being delivered on time, on budget and with high levels of participant satisfaction,” the spokesperson said.
