Turning 18 with the NDIS: who can see your information and help coordinate your supports?

What changes when an NDIS participant turns 18?

The NDIA's child-representative fact sheet says the role ends automatically when the participant turns 18. A parent does not automatically become an adult NDIS nominee. Talk with your my NDIS contact about the arrangements you want after the birthday and what needs to be recorded.

This is a change in NDIS representation. It is also a useful moment to look at everyday arrangements: who receives an appointment message, who helps prepare a question and who follows up an agreed action. Continuing to need that help does not mean the young person should be left out of the decisions.

Parents often hold years of useful knowledge about preferences, routines and services. Ask the young person how they want that knowledge used and shared. A familiar helper can remain important while the way they participate changes.

Start with the help you actually want

The NDIA's supported decision-making policy recognises adults' right to make decisions, with support to communicate and take part where needed. The amount and kind of help can vary between decisions. Needing help reading a letter or organising a meeting does not, by itself, mean someone else needs to make the decision.

Try discussing an ordinary situation. Would you like someone to read an appointment letter with you, explain the options or sit beside you during a call? Would you prefer to speak first and ask for help if needed? Those questions are often easier to answer than a broad question about who will 'manage everything'.

Make room for the person's communication style. They might want written questions ahead of time, pictures, a communication device, an interpreter or extra time with someone they know. A quick answer in a busy meeting is not the only way to express a preference.

Our supported decision-making care-team guide offers a way to prepare for one decision without asking a supporter to take over the whole conversation.

Check NDIA arrangements, provider sharing and app access separately

People sometimes use 'consent' to describe several different things. Knowing which arrangement you are discussing helps you ask the right organisation to confirm it.

An NDIA consent arrangement does not automatically update a provider's records or an app's membership. Being a named app user does not give someone authority to make NDIS or healthcare decisions. Check the actual arrangement for the particular organisation and decision.

Can parents still access their adult child's NDIS information?

A parent can remain involved where the appropriate consent or representation arrangement is in place. The NDIA's current consent guidance distinguishes sharing information from authorising someone to make requests or update details. It lets the participant choose the purpose and duration and change those choices later.

The same guidance says permission given during a phone call for someone to speak on your behalf applies to that call only. Written consent is needed if you want them to speak to the NDIA on your behalf on an ongoing basis or for a set period. An identity check still applies when the NDIA is contacted.

Check the NDIA's current instructions for giving consent rather than relying on an old form or assuming the childhood arrangement continues. They describe written requests and the consent form, including current ways to submit them. Ask for an accessible way to record your choices and confirmation of what the NDIA has recorded.

For provider reports and appointment communications, ask each service to explain its own requirements. If the question involves authority to consent to treatment or a guardianship arrangement, get advice relevant to that situation. NDIS consent information alone does not answer every question about healthcare or legal authority.

Does turning 18 mean you need an NDIS nominee?

A nominee is a separate arrangement, not an automatic part of becoming an adult. The NDIA explains the two nominee roles: a plan nominee deals with plan decisions and relevant funding matters, while a correspondence nominee receives NDIA communications and can request information. The same person may hold both roles, but the roles are different.

Ask the NDIA about decision support first and whether a nominee is needed in your circumstances. It establishes the appointment and its scope. Being a parent, carer or Kinovo Team leader does not appoint someone as a nominee.

A nominee's role includes listening to the participant's wishes and supporting their decision-making. If someone has difficulty communicating a preference, involve people and communication support that help them be understood. Do not assume a diagnosis or an unfamiliar way of communicating tells you everything about how they can take part.

A fictional example: staying involved without making every decision

Mika is approaching 18 and wants their dad, Chris, to keep helping with paperwork. Mika also wants appointment questions directed to them first. Their friend Rae helps them write down what they want to ask before a meeting.

Mika and Chris talk with their my NDIS contact about the relevant adult consent arrangements. They ask what Chris will be able to discuss or do, how long that arrangement will last and how Mika can change it. They do not assume Chris's existing child-representative role will carry over.

Separately, Mika asks the OT practice to explain how appointment reminders and report sharing can work. They want reminders sent directly to them, with Chris helping to organise the questions. The practice confirms what it needs to record. Rae does not need the OT report just because she helps Mika prepare.

The family then looks at its shared task list. Chris agrees to help prepare the questions for the next appointment. Mika will decide which questions to ask. The useful outcome is a clear agreement about the help Mika wants, with the formal permissions checked separately.

Agree a few practical next steps before the birthday

You do not need to resolve every future decision in one meeting. Start by agreeing who will contact the NDIA, which providers need a conversation and what the young person wants help with first. Ask each person to take responsibility for their own part and confirm when they will report back.

When sharing relies on consent, the OAIC's privacy guidance explains that it should be informed, voluntary, current and specific. A useful sharing conversation names the information, recipient and purpose. It also leaves room to say no or ask for a different arrangement.

Review the arrangements when circumstances or preferences change. That might be after a new service starts, someone leaves the team or the young adult wants to handle a task differently. Keep the confirmed outcome easy to find, and distinguish an unanswered request from a change that has actually been made.

Keep chosen supporters connected to the work they have agreed to do

Kinovo provides a participant-controlled shared workspace for relevant documents, preferences, goals, tasks and messages. It can help a young adult and their chosen supporters keep an agreed request, its response and the next action together, without expecting one family member to collect every update.

An authorised Team leader manages invitations and access. Review the actual members, roles and document audiences with the participant, including Team leader access, before adding private information. Kinovo permissions do not replace NDIA consent, provider requirements or legal authority; those arrangements need their own confirmation.

If a shared place for those everyday contributions would be useful, see how participants and families use Kinovo. Start with one priority the young person wants help with.
