Fifteen thousand people became eligible for the National Disability Insurance Scheme in July, but less than 2,000 of them have been approved.

IT issues are being blamed for the significant sluggishness, after federal, state and territory ministers responsible for the scheme met to look back on the first two months of the transition to the full NDIS rollout.

Dr Ken Baker from National Disability Services said it was good to know the politicians are paying attention.

“I think it is very important that the ministers do say that the scale and impact of the portal problems which have been quite severe over the last two months is quite unacceptable,” he told reporters.

The portal problem Dr Baker mentioned is just one of the computer issues plaguing the scheme.

PricewaterhouseCoopers (PwC) was recently commissioned to review the system, and found serious flaws that could leave it unable able to cope with the NDIS at full capacity, in about four years' time.

At the meeting over the weekend, the NDIS ministers agreed more resources were needed to avoid problems in other areas of the rollout.

The boost is set to start with the appointment of a chief operating officer.

Dr Baker says that shows the minister is worried.

“He's probably concerned that the problems of the portal do question the capacity of the agency to implement rapid change,” Dr Baker told the ABC.

Earlier computer problems meant disability service providers that Dr Baker represents were not being paid, but they fulfilled their roles regardless, and he says they deserve to be compensated.

“They have continued to provide services even when they haven't been getting payments for them and that is a reflection of their social purpose, their strong sense of mission,” he said.

“But this has cost them — the missing payments will be found and replaced but there has been a lot of administrative burden on providers.

“So I think frankly that providers deserve some compensation for that, not just an apology but some compensation.”
