When we think of disability, the first symbol that comes to mind for many people is a blue figure using a wheelchair - an image known as the International Symbol of Access (ISA) (Access Australia 2024).
Adopted as an international standardised symbol to indicate wheelchair-accessible environments, the ISA is now used in various settings to indicate a range of accessibility and disability-related matters.
Where the ISA arguably fails, however, is in its representation of the broader disability community. For instance, among the 4.4 million Australians (1 in 6 people) living with disability, only 4.4% use a wheelchair (Shrine of Remembrance 2022).
Does the International Symbol of Accessibility properly represent the broader disability community?
Invisible disability (or hidden disability) is an umbrella term used to describe disabilities that are not immediately noticeable when looking at someone. The term applies to a wide spectrum of conditions, including physical, mental and neurological disorders that impair daily functioning (IDA 2025).
Invisible disabilities include conditions such as chronic pain or illness, mental illness, injury and congenital disorders (Disabled World 2025).
It’s estimated that 8 out of 10 Australian people living with disability have an invisible disability (Life Without Barriers 2024).
Despite not being immediately obvious to others, invisible disabilities can cause significant daily challenges for those who have them (IDA 2025).
Because of their hidden nature, invisible disabilities can go unacknowledged, leading to a lack of sympathy and understanding within society (IDA 2025).
Sometimes, disability can be identified by the presence of aids such as canes or service dogs.

Supporting People Living With Invisible Disability
As stated by the National Disability Insurance Scheme (NDIS) Practice Standards (2021), disability support workers have a responsibility to provide supports that:
Are person-centred
Treat participants with dignity and respect
Promote participants’ individual values, beliefs, culture and diversity
Protect participants’ privacy
Allow independence and informed decision-making
Are free from violence, abuse, neglect, exploitation and discrimination.
With this in mind, the following practical tips may help you support people living with an invisible disability:
General considerations
If you know that someone is living with an invisible disability, ask them what they can and cannot do
Never force or convince someone to do something that they say they are unable to do
Encourage people living with invisible disability to participate in activities at a level they are comfortable with, and ask how you can support them to participate
Only offer assistance if the person wants it, and if they do, ask what they want you to do specifically
Speak directly to the person, not to those around them
Smile and be willing to communicate
Avoid handshakes as a default greeting
Never distract service dogs
People living with auditory impairment
Let the person establish their preferred method of communication (sign language, lip-reading, note writing etc.)
Talk to the person directly, even if they have an interpreter
If the person reads lips, face them directly when speaking. Speak clearly and at a moderate speed
Avoid finishing the person’s sentences for them
Be patient and pay attention while the person is speaking
Ask the person to repeat what they have said if you do not understand
Be prepared to communicate via computer, pen and paper, or an alphabet board if required
People living with visual impairment
Excuse yourself before leaving the person
If guiding the person, let them take your arm and walk slightly ahead of you
Never pull or push the person along
Be specific when describing nearby objects
People living with cognitive impairment
Keep communication simple
Rephrase statements if required
Pay attention to what the person is saying and how they respond to you
Be patient and give the person time to show or tell you what they want to communicate

Conclusion
In your professional life, you are likely to interact with many people living with invisible disability. Therefore, it is important to avoid making assumptions and always treat your patients with respect.
Even if you can’t visibly see the challenges they face, acknowledge and understand their experiences as best you can.
Additionally, remember that disability affects people in different ways, and for that reason, it is important to always provide individualised and person-centred care.
