Guardianship Consent And Supported Decision Making NSW

Guardianship, Consent and Who Decides: Supported Living in New South Wales

A support coordinator asks who signs the service agreement. The mother says she does, because she always has. Nobody asks on what authority, and for several years nothing turns on it.

Then something does. A medical decision, a change of house, a dispute with the provider, a question about money. And at that point it emerges that the arrangement everybody has been operating under for a decade has no legal basis at all — not because anybody acted badly, but because nobody asked the question when it was easy to ask.

This is an area where informality is the norm and the norm is a problem. It is worth understanding in advance, and it is specific to the state you live in.

The starting position: adults decide for themselves

In New South Wales, as everywhere in Australia, an adult is presumed to have capacity to make their own decisions. That presumption does not disappear because somebody has an intellectual disability, acquired brain injury, psychosocial disability or autism. It does not disappear because decisions take longer, need to be explained differently, or are decisions other people think unwise.

Capacity is also decision-specific and time-specific. A person may have capacity to decide what to eat and where to go and not have capacity to understand a complex financial transaction. A person may have capacity on a good day and not during an acute episode. There is no single switch.

The practical consequence for a supported house: the default decision-maker is the resident. Everything else is an exception requiring a reason.

What exists when the presumption does not hold

Several distinct arrangements, often confused with one another.

An enduring guardian. Appointed by the person themselves, while they have capacity, to make personal and lifestyle decisions if they later cannot. This is the option people most often wish they had set up and most often have not.

An enduring power of attorney. Likewise appointed by the person, but for financial and property decisions. Separate document, separate scope — an attorney cannot make lifestyle or medical decisions, and a guardian cannot operate a bank account.

A guardianship order from NCAT. The NSW Civil and Administrative Tribunal can appoint a guardian for personal and lifestyle decisions where a person cannot make them and there is a need. Orders are limited to specified functions — accommodation, services, health care, for example — and are reviewable, usually within one to three years. The Tribunal can appoint a private guardian, often a family member, or the Public Guardian.

A financial management order from NCAT. The equivalent for financial decisions, with a private financial manager or the NSW Trustee and Guardian.

The person responsible, for medical and dental consent. A NSW-specific concept that families frequently have not heard of and that operates every time somebody goes to a doctor. Where a person cannot consent to medical or dental treatment themselves, consent is given by the “person responsible”, determined by a statutory hierarchy: a guardian with health care functions first, then a spouse or de facto partner, then an unpaid carer, then a close friend or relative. Crucially, a paid support worker or provider is not the person responsible.

An NDIA nominee. Appointed by the National Disability Insurance Agency to act for a participant in dealings with the agency. This is scheme-specific and does not confer authority over medical decisions, housing or money generally.

A plan nominee or correspondence nominee. Narrower again, and purely about the NDIS plan.

The point of listing all seven is that they are not interchangeable. A person with an NDIA nominee but no guardian has no appointed decision-maker for accommodation. A person with a guardian but no financial manager has no appointed decision-maker for money. Houses operate on assumptions that collapse the moment a decision falls in the wrong category.

Supported decision-making, which is the preferred approach

Formal substitute decision-making is meant to be the last resort, not the starting point. The approach the NDIS framework and Australian law reform have both pushed toward is supported decision-making: building the support around the person so they make the decision themselves rather than having it made for them.

In a supported house that looks like concrete practices:

• information presented in a form the person can use — plain language, pictures, video, demonstration, time;
• decisions broken into parts, so a person who cannot decide everything can decide something;
• genuine experience of options rather than descriptions of them, which for housing means visiting rather than hearing about;
• a trusted person present who is not the provider;
• decisions revisited, because a first answer is not always a settled answer;
• and the person’s will and preferences recorded even where somebody else ultimately decides.

A provider that documents what the resident wants, separately from what the family wants, is doing this properly. A provider whose file contains only correspondence with relatives is not, however well-intentioned.

Where this actually bites in a supported house

Signing the service agreement. The contract for supported independent living is a decision like any other. If the resident has capacity, they sign. If they do not, whoever signs needs authority, and a service agreement is an accommodation and services decision — squarely within the functions a guardianship order would cover. An agreement signed by somebody with no authority is on shaky ground, which matters to the resident and to the provider. Our guide to reading a SIL service agreement covers what the document itself should say about this.

Moving house. One of the most significant decisions in somebody’s life, frequently made by a family and a provider together with the resident consulted rather than deciding. Where a guardian is appointed with accommodation functions, it is their decision; where nobody is appointed and the resident cannot decide, a decision is being made by people without authority to make it.

Medical treatment. The person responsible hierarchy applies and support staff are not in it. A house should know, in writing, who the person responsible is for each resident, before somebody is in an emergency department at 11pm.

Money. Covered in who controls the money in a supported house. Short version: unless there is a financial management order or an enduring power of attorney, nobody is authorised to be managing a resident’s money, and providers handling cash informally are exposed and so is the resident.

Restrictive practices. Regulated restrictive practices require authorisation in accordance with NSW requirements, a behaviour support plan developed by a registered NDIS behaviour support practitioner, and monthly reporting to the NDIS Commission. Consent from a family member is not authorisation. In the fourth quarter of 2025–26 the Commission recorded 16,640 participants subject to regulated restrictive practices, with 9,609 subject to environmental restraint and 10,354 to chemical restraint — and unauthorised use notifications of 3,034 for environmental restraint and 2,757 for chemical. Those unauthorised figures are what happens when consent is confused with authorisation.

Changing provider. An accommodation and services decision again. Worth settling who makes it before the relationship with a provider deteriorates rather than during, as set out in changing your SIL provider without losing your home.

The conflict of interest nobody names

A provider that delivers the support, controls the house, holds the resident’s money and influences who the decision-maker is has accumulated more power over one person’s life than any organisation should have.

None of those four is improper on its own. All four together, with no independent person in the picture, is the configuration in which things go wrong quietly. It is also the configuration that makes complaints least likely, because every route out of the situation runs through the organisation causing it.

The structural safeguard is simple to describe and often missing: somebody independent, with standing, who sees the person regularly. A family member, an advocate, a guardian who is not the provider, a support coordinator with no commercial relationship to the house. New South Wales has 4,048 registered behaviour support practitioners of 11,862 nationally, which is a useful proxy for how much external clinical attention exists in this state — but a practitioner is not an advocate, and the two roles should not be collapsed.

What to do, practically

1. Find out what is already in place. Enduring guardian, enduring power of attorney, NCAT orders, NDIA nominee appointment. Many families discover they have less than they thought, or more.
2. If the person has capacity, support them to appoint who they want. An enduring guardian and an enduring power of attorney, made now, are far better than an NCAT order later, because the person chooses.
3. Identify the person responsible for medical consent and write it down. Give it to the house and to the GP.
4. Do not seek a guardianship order by default. NCAT appoints where there is a need and no less restrictive alternative. Build the supported decision-making first and see what is genuinely left over.
5. If an order is needed, ask for narrow functions. Accommodation and services only, if that is what is needed. Broad orders remove more than necessary.
6. Keep the roles separate. The provider should not be the guardian, the financial manager, the advocate and the landlord. Where some of that is unavoidable, make sure somebody independent is in the picture.
7. Review it. Capacity changes, people change, orders expire. An arrangement set up at nineteen is rarely the right arrangement at thirty-five.
8. Get advice. NCAT publishes guidance on applications; the Public Guardian and NSW Trustee and Guardian publish material on their roles; disability advocacy organisations and community legal centres advise on all of it. Nothing on this page is legal advice.

The short version

Most supported houses run on arrangements that were never examined, and most of the time nothing turns on it. When something does turn on it, the people with the least protection are the residents, because every assumption in the house was made by somebody else.

Settling who decides what, in writing, while nothing is in dispute, is one of the few pieces of preparation in this field that costs almost nothing and occasionally matters enormously.
