National Disability Insurance Scheme Minister Linda Reynolds will push for major changes to the program when she meets with state and territory leaders on Friday.
People with disability will soon discover whether the states and territories back major changes to how their supports are calculated.
The federal government wants to introduce independent assessments for all National Disability Insurance Scheme (NDIS) participants and new applicants.
The changes are designed to rein in the annual cost of the NDIS, which is projected to reach $60 billion by the end of the decade.
Senator Reynolds argues the cost-cutting measure will also make the NDIS more fair and equitable.
