To get the NDIS your disability must be both permanent and significant. A permanent disability means it is likely to be with you for life. A significant disability affects your ability to take part in everyday activities. So you have to show you've got a disability that you're likely to have for your whole life and that stops you from doing everyday things.
You also have to be under 65 years of age when you apply, and be an Australian citizen or resident, or have a permanent visa.
Conditions and impairments which are likely to meet the NDIS requirements are:
Intellectual disability diagnosed and assessed as moderate, severe or profound; Autism having severity of Level 2 (Requiring substantial support) or Level 3 (Requiring very substantial support)
Cerebral palsy diagnosed and assessed as severe (e.g. assessed as Level 3, 4 or 5 on the Gross Motor Function Classification System - GMFCS)
Spinal cord injury or brain injury resulting in paraplegia, quadriplegia or tetraplegia, or hemiplegia where there is severe or total loss of strength and movement in the affected limbs of the body
Neurological conditions such as Parkinson’s disease and multiple sclerosis
Substantial vision impairment
Substantial hearing impairment
Amputation or loss of limbs
