Your Guide to Supported Decision Making in the NDIS
By the Vana Care team | 15 July 2025
Supported decision making is about giving you the tools and the team to make your own choices, with a bit of help from people you trust. It sits at the heart of the NDIS principle of choice and control. Put simply, it makes sure you're the one steering your own life and your NDIS plan.
What is supported decision making?
Think of it like putting together a personal board of directors for your life. Nobody buys a house alone; they talk to family, a conveyancer, maybe a financial adviser. Supported decision making gives that same idea a clearer structure, so you get the right help with decisions big and small.
The key is collaboration, not control. It starts from a simple belief: everyone has the right to make their own decisions, and with the right support, they can. That might mean someone helping you break down complex information, talk through your options, or tell others what you've decided.
This isn't just a nice idea. The National Disability Insurance Agency (NDIA) has a formal Supported Decision Making Policy that has been part of NDIS practice since 2023. It shapes the whole scheme, from applying, to setting your goals, to using your funding. If you're newer to the scheme, our NDIS overview explains where choice and control fits into the bigger picture.
It isn't one size fits all, either. The support you want for a small daily choice, like what to make for lunch, will look very different from the support you need when choosing a new place to live.
Levels of support in decision making
Your support network isn't a fixed team, it's a flexible circle of trust you can draw on as each decision comes up. This table shows how the level of support can shift.
| Level of support | What it looks like in practice | Example |
|---|---|---|
| Information gathering | Someone helps you research options or find accessible information. | A support worker helps you look up local art classes and their timetables online. |
| Exploring options | You talk through the pros and cons of different choices with a trusted person. | You chat with a family member about the benefits of two different job opportunities. |
| Communicating a decision | A supporter helps you express your final choice to others. | A friend comes to your NDIS planning meeting to help you explain your goals. |
| Collaborative choice | You and your supporters weigh up options together and arrive at a decision. | You trial three community programs with your support workers before choosing one. |
The right support is simply whatever helps you feel confident and in control of the decision you're making.
The principles behind it
The presumption of capacity
Everything starts with a simple but profound shift in thinking: the default position is that you can make your own decisions, given the right support. Instead of asking "can this person make a choice?", we ask "what support does this person need to make their own choice?". It pairs naturally with strength-based, person-centred support, which starts with what you can do rather than what you can't. Our guide to the strength-based approach covers that philosophy in more detail.
The dignity of risk
The dignity of risk is a formal name for something most of us take for granted: the right to make choices that might not be perfectly safe. It's how we all learn, grow and live a full life.
Say someone wants to join a community art class, but getting there means catching two buses. The old-school response might be to shut the idea down as too risky. With supported decision making, the conversation looks for solutions together:
- Practising the bus route a few times with a support worker.
- Working out a backup plan in case a bus is late or missed.
- Learning to use a public transport app to track buses in real time.
The person's choice is respected, and they build skills and confidence along the way. Shielding people from every possible risk usually leads to a smaller life, while working through a challenge builds real independence.
Underneath it all sit two values: respect for who you are, how you communicate and the choices you make (even when they aren't the ones we'd make ourselves), and autonomy, recognising that you're the expert in your own life.
Why this matters for NDIS participants
Day to day, this is far more than a process on paper. Owning a decision from start to finish builds genuine confidence and a real sense of purpose.
The skills ripple out well beyond your plan, too: managing a weekly budget, planning meals, making new friends, getting around your local community. Many participants, particularly people with intellectual disability or autism, have family or others closely involved in managing their plans. Supported decision making helps close the gap between having a plan and genuinely directing it.
When you're actively involved in a decision, you're more invested in the outcome. Your NDIS plan stops being something that happens to you and becomes a tool you use to build the life you want. The same goes for the paperwork you sign with providers; our guide to NDIS service agreements explains what to check before you commit.
How to build your support circle
It all starts with gathering your people. Your circle doesn't have to be just family; it can mix friends, mentors and allied health professionals. You want people who truly listen, respect your right to choose, and help you gather information rather than deciding for you. A few roles worth thinking about:
- The listener: who is great at hearing you out without jumping in with their own opinions?
- The researcher: who loves digging into things and can break down complex information in a way that clicks for you?
- The encourager: who genuinely believes in your ability to tackle whatever comes your way?
- The practical thinker: who can help you map out pros and cons or work through the steps of a plan?
The single most important quality in any supporter is trust. Their job is to turn up the volume on your voice, never to speak over you.
Once you have a few people in mind, reach out and explain that you're building a team to help you make your own decisions. Be clear about what you need: you might ask one person to help you research local programs, while another helps you explain your final choice at your next planning meeting.
Putting it into practice
A good first step is to slice big, overwhelming decisions into smaller pieces. "Where should I live?" can feel paralysing. Broken down, it becomes much more approachable:
- What suburb do I enjoy spending time in?
- Do I want to live by myself, or with housemates?
- Is it important to be close to family, work or public transport?
Communication tools help too, and they don't need to be high-tech. A picture board, an emotions chart or an app on a tablet all count, as long as it helps you express your preferences clearly to your support network.
Supported versus substitute decision making
The two sound similar but are worlds apart. Supported decision making helps you make your own choice. Substitute decision making is when someone else holds the legal authority to choose for you.
| Feature | Supported decision making | Substitute decision making (e.g. guardianship) |
|---|---|---|
| Who decides | You make the final decision. | A legally appointed substitute, such as a guardian, makes the decision. |
| Focus | Building your skills and confidence to choose for yourself. | Protecting you by making a decision judged to be in your best interests. |
| Your role | You are the central figure, the one in control. | You receive a decision made on your behalf. |
| Rights | Presumes you have the capacity to decide with the right support. | Used only when a person is legally assessed as unable to decide. |
Supported decision making is the default approach under the NDIS because it honours your right to be the main decision maker in your own life.
How Vana Care backs your choices
At Vana Care, this philosophy is summed up in a phrase we live by: doing with, not for. Our support workers across community access, in-home support and supported independent living are trained to support your choices, not make them for you.
In practice, that looks like real collaboration. People we support often want help choosing a new community program. Rather than presenting one pre-selected option, our support workers help research programs that match the person's interests, organise visits to try the frontrunners firsthand, and talk through what felt right afterwards. The final decision belongs entirely to the person, made with confidence because it's based on their own experience. And if you need something we don't provide, such as support coordination or plan management, we'll happily point you in the right direction.
Common questions
What if a decision seems risky?
This is a fair concern, and the dignity of risk is the answer. Instead of a flat "no", the question becomes "how can we make this happen safely?". The support circle plans collaboratively: practising the skill, building a backup plan, and growing confidence step by step. The focus moves from avoiding risk entirely to managing it intelligently.
Can someone have a nominee and still use supported decision making?
Yes, absolutely. A nominee is legally recognised to make certain decisions on a participant's behalf, but a good nominee uses supported decision making principles so the participant's wishes guide every choice. They simply become a trusted member of the support circle.
How do we handle disagreements?
Disagreements happen in any team, and a support circle is no different. When one pops up, the conversation should come back to the most important question: what does the person at the centre actually want? It can help to bring in a neutral third party such as an advocate, trial an option on a small scale before committing, or gather more information so everyone understands the choice fully.
Your choices should always be the starting point of your support, never an afterthought. If you'd like a team that works that way, you can build a quote in a few minutes at Get Support or call us on 08 7228 6202 for a friendly chat about what supported decision making could look like in your plan.
