Is an Advance Care Directive Legally Binding in Victoria?

Victoria Has the Strongest Advance Directive Framework in Australia

Yes, an advance care directive (ACD) in Victoria is legally binding — and it's more powerful than equivalent documents in most other Australian states.

Under the Medical Treatment Planning and Decisions Act 2016, a valid ACD containing an instructional directive is binding on health practitioners. This means a doctor must follow your documented medical treatment instructions as if you were making the decision with full capacity in the room. Your MTDM cannot override it. Your family cannot override it. The treating team cannot substitute their clinical judgement.

This is a deliberately high standard. Victoria's framework was designed to give individuals genuine control over their future medical care — control that persists even when they can no longer speak for themselves.

What "Legally Binding" Means in Practice

When a Victorian ACD contains a valid instructional directive — for example, "I refuse cardiopulmonary resuscitation" — and the patient loses decision-making capacity, the health practitioner treating them must:

1. Make reasonable efforts to discover whether an ACD exists (checking the patient record, My Health Record, and asking the MTDM or family).
2. If an ACD is found with a relevant instructional directive, treat that instruction as a direct consent or refusal from the patient.
3. Follow the instruction. Not "consider" it, not "weigh it against clinical judgement" — follow it.

A clinician who ignores a valid instructional directive is breaching their statutory obligations under the 2016 Act. This is a significant departure from many other jurisdictions, where advance directives are treated as advisory rather than mandatory.

The Exceptions — When a Directive Can Be Set Aside

The binding nature isn't absolute. There are narrow circumstances where a health practitioner can depart from an instructional directive:

The directive doesn't apply to the situation. If your ACD refuses a specific treatment in a specific scenario, and the clinical situation is materially different from what you described, the instruction may not be applicable. This is why precise, clinically worded instructions matter — vague language creates room for interpretation.

The directive was made without capacity. If there's evidence that you lacked decision-making capacity when you signed the ACD, the document is invalid. This is the most common challenge pathway and the reason a contemporaneous capacity assessment is worth having.

Improper execution. If the ACD wasn't properly witnessed — for example, if one witness wasn't a registered medical practitioner, or if the witnessing was done via video link — the document doesn't meet the statutory requirements and isn't binding.

Compulsory mental health treatment. Under the Mental Health and Wellbeing Act 2022, an authorised psychiatrist can override an ACD's preferences regarding mental health treatment if the patient is subject to a compulsory treatment order and the preferred treatment is clinically inappropriate or unavailable. The psychiatrist must provide written reasons for the override.

Values Directives Are Not Binding in the Same Way

A values directive — where you describe your priorities, quality-of-life thresholds, and what matters to you — is not binding on clinicians in the same direct way as an instructional directive. Instead, a values directive guides your Medical Treatment Decision Maker in making decisions that aren't covered by your instructional directives.

This distinction is critical for document planning. If you want a specific treatment refusal to be binding (no CPR, no ventilation, no artificial nutrition), it must be written as an instructional directive in clear clinical language. If you express it as a values statement ("I don't want to be kept alive artificially"), it may be treated as guidance rather than a command.

How Other States Compare

Victoria's binding framework is unusual in Australia. A quick comparison:

• NSW and Queensland: Advance health directives carry legal weight but the enforcement mechanisms are less explicit than Victoria's.
• South Australia and Tasmania: Advance care directives are binding on health practitioners, similar to Victoria, but the witnessing requirements differ.
• Western Australia: Uses advance health directives under specific statutory conditions.
• ACT and NT: Have their own frameworks with varying levels of binding authority.

Victoria's 2016 Act is widely regarded as the most robust framework in the country, precisely because it was designed to eliminate the ambiguity that plagued earlier advance directive systems.

Making Yours Hold Up

A binding directive that isn't properly executed is just a piece of paper. Three things determine whether your ACD actually works when it matters: clinical precision in the language (specific treatments named, specific scenarios described), correct statutory execution (two witnesses, one a doctor, all physically present), and distribution to the places where clinicians will look for it (GP record, hospital files, My Health Record).

The Victoria Advance Directive & Living Will Kit is built around these three requirements, with clinician-approved phrasing templates, a signing checklist, and a distribution log designed for the 2016 Act framework.
