Nobody will miss out on NDIS, govt says

The federal government has promised nobody will miss out on the national disability insurance scheme despite concerns some children will be locked out.

The scheme has also pledged support for people with mental illness, as long as their disability inhibits their daily activity.

South Australia, which is trialling the scheme for children under 13, says its rollout is six months behind and some kids are set to miss out.

State disability minister Tony Piccolo will use a disability reform council meeting on Friday to call for the early access to a special fund set up to finance the scheme.

He argues a massive backlog in trials is causing frustration and financial pain for families and service providers, and wants funds to cover extra children.

Assistant Social Services Minister Mitch Fifield says the Commonwealth is open to requests for access to the DisabilityCare Australia Fund, to which taxpayers contribute 0.5 per cent through the Medicare levy.

But he blamed the Weatherill government for the backlog, saying it massively underestimated the number of children who'd be eligible for the trial.

But while acknowledging delays processing entrants, Senator Fifield pledged that anyone who was not receiving support under existing schemes will be fast-tracked through the NDIS.

"No one will miss out," he said.

The minister also addressed concerns people with a mental illness could be excluded from the scheme.

Some 50,000 people would be eligible if their mental illness affected their daily functional capacity, he said.

Meanwhile, disability campaigners want the ministers to tackle at their meeting in Melbourne what they say is a crisis in disability housing.

Every Australian Counts has released a report urging them to take action on a housing solution.

The group's director John Della Bosca says if nothing is done, there will be more than 100,000 disabled Australians without adequate housing in a few years.
