A disability is any continuing condition that restricts everyday activities. The Disability Services Act (1993) defines disability as a condition that:
- is attributable to an intellectual, cognitive, neurological, sensory or physical impairment or a combination of those impairments
- is permanent
- may or may not be episodic in nature.
Disabilities can result in a person having a substantially reduced capacity for communication, social interaction, learning or mobility and a need for continuing support services in daily life. Some disabilities, such as epilepsy, are hidden while others, such as cerebral palsy, may be visible.
With the assistance of appropriate aids and services, the restrictions experienced by many people with a disability may be overcome.
