Is PTSD a Disability?

Last updated 26 October 2026 · 5 min read · By Sarah M., Support Coordinator
In short

Is PTSD a disability? Yes, it can be in Australia. The Disability Discrimination Act 1992 includes psychiatric disability and its definition is broad and does not rely on a formal diagnosis, while the NDIS and Disability Support Pension have their own tests. See our wider guide to whether a chronic illness is a disability.

Is PTSD a disability: what it means

“Disability” has a different meaning in discrimination law, the NDIS and Centrelink, so one answer does not cover all three.

TermMeaningExample
Disability (Disability Discrimination Act 1992)Includes physical, intellectual, psychiatric, sensory, neurological and learning disability, covering disability a person has now, had in the past, may have in future, or is perceived to haveA workplace treating someone unfairly because of their PTSD may raise discrimination issues
Psychosocial disabilityA disability that can arise from a mental health condition; the NDIA says not everyone with a mental health condition will experience itDifficulty with daily tasks, relationships or leaving home because of PTSD symptoms
Permanent impairment (NDIS)An impairment that substantially reduces functional capacity, where the person will likely need NDIS supports for lifeSupport needs that are likely to last for life
Impairment (Disability Support Pension)A physical, intellectual or psychiatric impairment attracting at least 20 points under the Impairment Tables, expected to persist for at least 2 yearsAn impairment that leaves someone unable to work 15 or more hours a week for the next 2 years

The Australian Human Rights Commission explains the definition under the Act.

Is PTSD a mental disability or a psychiatric one? Under discrimination law it can be classed as a psychiatric disability, while the NDIS and Disability Support Pension each apply their own tests.

  • Discrimination law: the definition of disability under the Act is broad and does not rely on a formal diagnosis, according to the Department of Education’s fact sheet.
  • NDIS: to meet the NDIS disability requirements, a permanent impairment must substantially reduce functional capacity and you will likely need NDIS supports for life; impairments can relate to psychosocial disability (NDIA).
  • Psychosocial disability: the NDIA says applicants must show their condition’s impact on functioning is likely to be permanent, and it recognises mental health conditions are often episodic and fluctuating (NDIA).
  • Disability Support Pension: the impairment must be expected to persist for at least 2 years and leave you unable to work 15 or more hours per week for the next 2 years (Department of Social Services).
  • Evidence: for the pension, an impairment rating needs a diagnosis from an appropriately qualified medical practitioner, reasonable treatment and a stabilised condition.
  • NDIS age limit: to apply you must be aged 0 to 64.

Ask your treating doctor or psychologist for a letter that describes how PTSD affects your daily life, since decision-makers look at function, not just diagnosis.

Is PTSD a permanent disability, and is complex PTSD a disability too?

The NDIS and Disability Support Pension tests above look at impairment, functioning and how long it is likely to last, whether the diagnosis is PTSD or complex PTSD.

  • NDIS guidelines say a diagnosis on List A means the NDIA will likely decide you meet the disability requirements, and a List B diagnosis means it will likely decide your impairment is likely to be permanent (NDIS guidelines); check the guidelines to see which conditions are listed.
  • Symptoms that come and go can still be considered; the NDIA recognises mental health conditions are often episodic and fluctuating.
  • Talk to your GP or psychologist about what to expect for you, because outcomes vary between people.
  • Is CPTSD a disability? It can be, under the same tests, so ask your clinician for evidence that describes your own situation.
  • Read ADHD and trauma if you live with both.

Common questions

FAQs about PTSD and disability

Is PTSD classed as a disability, and is CPTSD a disability? +

It can be, and complex PTSD (CPTSD) is judged the same way. The Disability Discrimination Act 1992 includes psychiatric disability and does not rely on a formal diagnosis. The NDIS and Disability Support Pension have their own tests, including how the condition affects your functioning or capacity to work and how long it is likely to last.

Is PTSD a psychosocial disability? +

It can be, but the NDIA says not everyone with a mental health condition will experience psychosocial disability. Applicants must show the impact on functioning is likely to be permanent, and the NDIA recognises that mental health conditions are often episodic and fluctuating.
