Carers of teenagers with disabilities say their Centrelink payments are being cut off and that some parents are going without support for months while paperwork is assessed.
The federal government requires people who are receiving the carer allowances to transfer it to an adult payment when their child turns 16.
Carers have to complete a tedious process of submitting forms that prove their child's identity, detail their caring routine, their child's disability, behaviour and submit a new medical report from the child's treating health professional.
Disability carers have blamed delayed information processing at Centrelink for their payments being cut off.
