Guardian

A person appointed, often by a tribunal, to make certain personal or lifestyle decisions for someone who cannot. Different from a nominee.

What it means

A guardian is a person who is legally appointed to make certain personal or lifestyle decisions for an adult who has been assessed as unable to make those decisions on their own. This can cover choices such as where the person lives, the services they receive, or aspects of their health care and medical treatment.

Guardianship comes from state and territory law, not from the NDIS. In most places, a guardian is appointed by a tribunal or court after an assessment, and the appointment sets out exactly which kinds of decisions the guardian can make. A guardian is different from an NDIS nominee, who acts specifically in relation to a person's NDIS plan.

In practice

A guardian only steps in for the specific areas covered by their appointment, and the aim is to make decisions that reflect what the person would want and that are in their best interests. Guardianship is generally seen as a last resort, used only when supported decision-making and other, less formal options are not enough.

In everyday life, a guardian might help decide on an accommodation arrangement or consent to a health treatment. Some appointments are time-limited and reviewed regularly. Because the rules and tribunal names differ between states and territories, it is worth checking how guardianship works where you live, and how it fits alongside any NDIS nominee arrangement.

A real example

For example, Marcus has an acquired brain injury and, after an assessment, a state tribunal appoints his sister as his guardian for decisions about where he lives and his medical care. When a new supported accommodation option comes up, she works through the choice with Marcus and his support team before agreeing to it. Her role is limited to those personal and health decisions, and it is separate from anything to do with his NDIS plan.

Guardian — FAQs

Is a guardian the same as an NDIS nominee?
No. A guardian is appointed under state or territory law to make personal or lifestyle decisions, such as where someone lives or their health care. An NDIS nominee is appointed under the NDIS specifically to help with decisions about a person's NDIS plan. A person may have one, both or neither, and the two roles cover different things.
Who appoints a guardian?
In most states and territories a guardian is appointed by a tribunal or court, usually after an assessment showing the person cannot make certain decisions themselves. The appointment sets out which decisions the guardian can make. The names of the tribunals and the exact processes vary between states and territories, so it helps to check the rules where the person lives.
What decisions can a guardian make?
A guardian can only make the decisions listed in their appointment. These are usually personal or lifestyle matters, such as where the person lives, the services they use, or their health care and medical treatment. A guardian does not automatically handle money or property; financial matters are usually covered by a separate administrator or financial manager role.
Does having a disability mean someone needs a guardian?
No. Having a disability does not mean a person needs a guardian. The starting point is that adults can make their own decisions, and many people are supported to do so without any formal appointment. Guardianship is generally a last resort, used only when a person is assessed as unable to make specific decisions and less formal support is not enough.
Can a guardianship arrangement be changed or ended?
Yes. Guardianship appointments are usually reviewed by the tribunal that made them, and many are time-limited. If a person's situation changes, the arrangement can be reviewed, changed or ended. The person, their family or others involved can often ask for a review. Because processes differ, check how reviews work in your state or territory.
