State leaders are criticizing the federal government's plans to cut the National Disability Insurance Scheme (NDIS) by reducing the number of participants from 760,000 to 600,000 by the end of the decade. The changes, which include a crackdown on unregistered providers and a reduction in participants, have been announced ahead of the federal budget. State leaders, including premiers and ministers, are expressing concern that the cuts will leave vulnerable people without access to essential services and will put pressure on state health systems. They are calling for more consultation and clarity on how the changes will work, and for the federal government to be honest with the public about the impact of the cuts.
