What Changes When A Young Person With Disability Turns 18?

Turning 18 is an important milestone for any young person, but for families of someone living with a disability, it can also bring a new set of questions. What happens to their existing supports? Can parents or carers still be involved in decisions? In this guide, Lumia Care explains what happens when a disabled child turns 18 and the practical steps families can take to prepare for the transition into adulthood.

What happens when a young person with a disability turns 18?

When a young person with a disability turns 18, they are legally recognised as an adult. For families, some of the main changes may include:

• Personal responsibility — The young person generally takes greater responsibility for their own care, supports and services.

• Consent and privacy — Providers may need the young adult’s permission before sharing personal or health information with parents or carers.

• Future support goals — Their priorities may also begin to shift towards adult goals such as work, further study, community participation or living more independently.

Who makes decisions after they turn 18?

Once a young person turns 18, they are generally responsible for making decisions about their own NDIS plan, supports and services. If a parent or carer has been acting as their child representative, that role ends when the participant becomes an adult.

This does not mean families are suddenly excluded. The young person can still choose to involve parents, carers or other trusted people in conversations and decisions, and they can give consent for information to be shared with them. Where appropriate, an NDIS nominee may also be appointed to help with certain decisions.

Do disability support services change when they turn 18?

Turning 18 does not automatically mean a young person’s disability supports stop or need to be replaced. However, it can be a useful time to review whether their current supports still reflect their goals, routine and plans for adulthood.

As priorities change, support may begin to focus more on:

• Further study or employment — Building skills and confidence for education, training or work.

• Community participation — Taking part in social activities, appointments, programs or other interests outside the home.

• Independent living skills — Developing everyday abilities such as meal preparation, household tasks and managing routines.

• Transport and mobility — Finding reliable ways to travel to work, study, appointments or community activities.

What should families organise before their child turns 18?

Part of knowing what to do when a disabled child turns 18 is making sure essential documents and permission are up to date.

• Assess the current NDIS plan — Check whether existing goals and funded supports still reflect what the young person may need as they move into adulthood.

• Discuss future family involvement — Talk with the young person about how involved they would like parents, carers or other trusted people to remain in appointments, planning and communication.

• Organise consent or nominee arrangements — Where appropriate, make sure the correct permissions are in place for family members or trusted people to continue receiving information or assisting with NDIS matters.

• Check online account access — Make sure the young person can access relevant accounts, including myGov and their NDIS participant portal, or knows who can assist them.

• Update important health information — Go through medication lists, healthcare contacts, emergency information and current support or care plans to make sure they are still accurate.

How can families support greater independence after 18?

Here are a few ways families can create more space for young adults to take the lead:

• Giving them a stronger voice in appointments — Encourage them to answer questions, raise concerns and speak about their own goals wherever possible.

• Building everyday skills gradually — Practise tasks such as planning meals, managing a routine, using transport or organising appointments at a pace that feels achievable.

• Creating opportunities outside the home — Community activities, day programs, further education, training or employment can help build confidence and social connection.

Can my child apply for the Disability Support Pension when they turn 18?

Yes, if they meet the eligibility requirements. However, your child does not actually need to wait until 18 to apply for the Disability Support Pension (DSP). Services Australia allows eligible young people to receive DSP from age 16, and a claim can be started up to 13 weeks before their 16th birthday.

Eligibility is not based on having a disability alone. Services Australia looks at both medical and non-medical requirements, including the impact of the person’s condition on their ability to work, as well as residence, income and assets rules.

If your child is already receiving DSP, turning 18 may still affect the rate they receive. Different rates apply to people under 21 depending on factors such as whether they are assessed as dependent or independent.
