The National Disability Insurance Scheme has come under fire after refusing to fund a $10,000 hearing upgrade for a deaf man.

The NDIS instead provided $15,000 to be used for core supports to assist with daily living and participation, but funneled these funds directly through to the support provider.

Rockhampton local Mr Dobson had his first cochlear implants 15 years ago, and was planning to use the money to purchase a new speech processor, capable of connecting to a smartphone to make calls easier for the deaf and hearing impaired.
