Key Points

  • Children with Down syndrome under 9 access NDIS through the Early Childhood Approach without a formal access decision; after age 9, a formal access request is required but is almost always approved
  • Early childhood priorities are speech pathology (language development), OT (fine motor and sensory processing), and physiotherapy (gross motor and muscle tone); intensity varies by individual developmental profile
  • The I-CAN assessment tool rolled out from September 2025 for participants over 16; families should ensure assessors have intellectual disability and Down syndrome experience
  • Adults with Down syndrome can access supported employment, community participation, independent living supports, and ongoing allied health through NDIS
  • People with Down syndrome have an increased risk of early-onset Alzheimer’s disease; support coordinators should plan ahead for dementia-specific supports within the NDIS age range
  • Down Syndrome Australia and its state affiliates provide life-stage specific guides, NDIS navigation support, and peer networks

Down Syndrome and the NDIS

Down syndrome is a chromosomal condition caused by the presence of a third copy of chromosome 21, resulting in characteristic physical features, intellectual disability ranging from mild to moderate, and variable health impacts. In Australia, Down syndrome affects approximately 1 in 700 births, making it one of the most common genetic conditions.

The NDIS provides individualised funding for people with Down syndrome across their entire lives. The supports needed, and the provider team required to deliver them, change substantially across life stages. A plan that works well for a three-year-old bears little resemblance to one appropriate for a 30-year-old.

This guide covers NDIS supports, provider types, and planning considerations from early childhood through adulthood, including the transition to aged care that families with older adults with Down syndrome need to prepare for.


Early Childhood (Birth to Age 9)

The Early Childhood Approach

Children with Down syndrome under 9 access NDIS through the Early Childhood Approach. This pathway does not require a formal NDIS access decision. The family contacts an Early Childhood Partner (a disability or early childhood organisation commissioned by the NDIA) who provides supports and helps determine whether a formal NDIS plan is appropriate.

Most children with Down syndrome eventually receive a formal NDIS plan through this pathway. The Early Childhood Partner coordinates therapy referrals, supports the family to understand available services, and helps establish early intervention.

Priority Therapies in Early Childhood

Speech Pathology: Language and communication development is significantly affected in Down syndrome. Speech pathologists address: pre-verbal communication (eye contact, joint attention, gesture), early vocabulary development, language comprehension and expression, articulation and phonology (the sound system of language), and early literacy skills. Augmentative and alternative communication (AAC) may be introduced to support communication before verbal speech develops.

Occupational Therapy: OT in early childhood for Down syndrome covers fine motor skills (grasping, manipulation, drawing, self-care tasks), sensory processing (hypersensitivity or hyposensitivity common in Down syndrome), self-care skill development (dressing, feeding, toileting), and school readiness.

Physiotherapy: Hypotonia (low muscle tone) is universal in Down syndrome and affects gross motor development (sitting, standing, walking). Physiotherapy addresses motor milestone development, strength, coordination, and later, participation in sport and physical activity.

Early Intervention Programs: Many families also access group-based early intervention programs that combine therapies with social skill development and peer interaction.

Health Monitoring in Early Childhood

Down syndrome is associated with increased rates of specific health conditions requiring monitoring in early childhood: congenital heart defects (present in approximately 40% of children with Down syndrome), hearing impairment (from recurrent otitis media), vision problems, thyroid dysfunction, and atlanto-axial instability (instability in the upper cervical spine). Health monitoring guidelines for Down syndrome are available from the Down Syndrome Medical Interest Group Australia (DSMIG-A) and should be discussed with the child’s paediatrician.


School Age (9 to 18 Years)

The Transition at Age 9

At age 9, the Early Childhood Approach ends. Families must submit a formal NDIS access request to continue receiving funding. For Down syndrome, approval is effectively certain given that the condition causes permanent intellectual disability, but the transition requires preparation.

Families should gather updated reports from all therapists ahead of the transition and ensure the access request documentation clearly describes how Down syndrome affects daily functioning, not just lists the diagnosis.

Down Syndrome Australia provides a specific transition guide for this age milestone, including what evidence to gather and how to frame the access request.

School-Age Provider Team

OT: Handwriting, classroom and school environment modifications, assistive technology for learning, and participation in school activities. The OT may complete a school-based assessment and work with teachers and support staff.

Speech Pathologist: Ongoing language development, literacy support, social communication skills, and support for curriculum access. Adolescence brings additional communication goals: conversation skills, assertiveness, and workplace communication.

Physiotherapy: Physical fitness, coordination, community sport participation, and health monitoring.

Behaviour Support Practitioner: For students with significant behavioural support needs in school settings.

Support Coordinator: Navigates the plan, coordinates providers, and manages the school-to-adult services transition from approximately age 16 onwards.

The I-CAN Framework (16 and Over)

From September 2025, the NDIA began rolling out the I-CAN assessment tool for participants over 16. I-CAN replaces standalone Functional Capacity Assessments for determining plan funding and support types. Down Syndrome Australia has recommended families ensure assessors understand intellectual disability and the specific profile of Down syndrome, which may not be fully captured by generic assessment approaches.


Adulthood (18 Years and Over)

Adult NDIS plans for people with Down syndrome focus on independence, employment, community participation, relationships, and quality of life. The specific supports depend entirely on the individual’s goals, capacity, and preferences.

Supported Employment

Adults with Down syndrome can work in a range of settings with appropriate support. NDIS funds employment supports through Capacity Building, and the Disability Employment Services (DES) system (separate from NDIS) provides ongoing job coaching for people in open employment.

Evidence consistently shows that people with Down syndrome succeed in competitive employment when job role and support are well matched. The support coordinator or employment specialist can help identify appropriate roles and facilitate workplace relationships.

Community Participation

NDIS Core Supports fund community access and social participation activities. For adults with Down syndrome, this might include supported attendance at community groups, cultural activities, sport and recreation, and social outings. Community participation supports are important for mental health and quality of life, particularly as peer networks from school dissolve in adulthood.

Independent and Supported Living

Many adults with Down syndrome live at home with family, in supported independent living (SIL) arrangements, or with low-level in-home support in their own or shared accommodation. NDIS funds SIL for participants who need regular support during the day and overnight and may fund Specialist Disability Accommodation (SDA) for those with very high housing and support needs.

Ongoing Allied Health

Adults with Down syndrome benefit from ongoing OT (independence skills, assistive technology, home modification), speech pathology (communication, literacy, workplace communication), and psychology (emotional wellbeing, social relationships). The frequency of therapy typically reduces from childhood levels but should not cease entirely.


Planning for Dementia and Ageing

Adults with Down syndrome have a significantly elevated risk of Alzheimer’s disease, often beginning in the late 30s to 40s, approximately 20 to 30 years earlier than the general population. By age 65, most people with Down syndrome have Alzheimer’s disease.

Support coordinators and families should begin monitoring for early signs of cognitive change from approximately age 35 and include a baseline cognitive assessment during this period. When dementia develops in a person with Down syndrome who is still within the NDIS age range (under 65), the NDIS plan should include dementia-specific supports including behaviour support and additional personal care.

At age 65, NDIS participants transition to the aged care system. For people with Down syndrome who have dementia at that point, this transition requires careful coordination to ensure continuity of dementia-specific supports.
