- Spinal cord injury or brain injury resulting in paraplegia, quadriplegia or tetraplegia.
- Hemiplegia where there is severe or total loss of strength and movement in the affected limbs of the body.
- Permanent blindness in both eyes, diagnosed and assessed by an ophthalmologist as follows:
- Corrected visual acuity (extent to which an object can be brought into focus) on the Snellen Scale must be less than or equal to 6/60 in both eyes; or
- Constriction to within 10 degrees or less of arc of central fixation in the better eye, irrespective of corrected visual acuity (i.e. visual fields are reduced to a measured arc of 10 degrees or less); or
- A combination of visual defects resulting in the same degree of visual impairment as that occurring in the above points. (An optometrist report is not sufficient for NDIS purposes.)
- Permanent bilateral hearing loss > 90 decibels in the better ear (pure tone average of 500Hz, 1000Hz, 2000Hz and 4000Hz).
- Deafblindness confirmed by ophthalmologist and audiologist and assessed as resulting in permanent and severe to total impairment of visual function and hearing.
- Amputation or congenital absence of 2 limbs – for example, 2 legs, 2 arms, or a leg and an arm (not a leg and a hand, or an arm and a foot).
