National Disability Services state manager Will Kestin says the state will have a shortfall of about 5500 workers to service the National Disability Insurance Scheme once it is fully rolled out in Tasmania from July.
New data released by the federal government has revealed the workforce needs for regional Tasmania to manage the full transition to the NDIS.
The data has been broken down by postcodes and show the estimated number of clients, annual spending on services, and the workforce required to maintain services.
It shows the North-West and West Coast will need up to 1470 workers by 2023 and the North and East Coast regions will need 990 workers.
The bulk of these positions are for personal carers but also include occupational therapists, physiotherapists, psychologists, speech therapists and other professional services.
Mr Kestin said there were currently 2500 vacancies with disability service providers across Tasmania and there would need to be an extra 3000 workers within the sector once the NDIS roll-out was completed.
He said the sector employed 7000 workers in the state though there were staff retention issues and recruitment problems.
Disability support workers needed to do more training than support workers in aged care but were paid less for their work, Mr Kestin said.
"We're the fastest growing employers in the state yet we struggle to find a staff of support workers as the pricing for one-on-one care under the NDIS isn't high enough," he said.
Mr Kestin said one of the reasons the NDIS had worked well in the state since the roll-out began six years ago was because providers had underwritten the system's inefficiencies and inadequate funding through pricing schedules.
"We've got huge delays in plans being approved, we've got huge delays in payments for providers, we've got huge delays on plans going into review because the plans themselves are not adequate to fund people," he said.
"When a plan goes into review, nobody gets paid so providers are expected to continue to provide disability services with no compensation until that plan is out of the review.
"Some of those plans can take anywhere between six to nine months to review."
The government's NDIS workforce strategy acknowledged there needed to be a balance between costs of the scheme and the disability sector's sustainability in maintaining services.
The strategy stated the government was considering price deregulation but would for now continue to benchmark prices against the cost of similar service delivery.
