State governments need to stop treating the country's disability scheme as a "dumping ground" for criminals, NDIS Minister Bill Shorten has warned.
Mr Shorten will write to the states to demand they inform the National Disability Insurance Agency when serious criminals are released from their jails.
Sex offenders with intellectual disabilities are among those receiving support from the NDIS to live in the community under supervision after serving their prison terms.
Describing the issue as "festering" in the scheme for a decade, Mr Shorten said the Albanese government had taken action to stop criminals from self-managing their NDIS plans.
"The NDIS cannot be responsible for criminals who are on parole," he said.
"The NDIS cannot be the dumping ground for state justice systems to keep Australians safe from violent criminals.
"Being a criminal is a not a disability. Being a sex predator is not a disability."
He said the issues were "clearly" law and order areas within the jurisdiction of the states.
"I don't recall being made the chief justice, the chief commissioner or the chief parole officer of the states and territories," Mr Shorten said.
The NDIS is one of the biggest pressure points on the federal budget as costs continue to blow out.
