Informed Consent in Tasmania

What is this right?
Before any medical treatment, you have the right to receive enough information to make an informed decision. This principle comes from the landmark High Court case Rogers v Whitaker (1992), which established that a doctor must tell you about any material risk — that is, any risk that a reasonable person in your position would want to know about.
The Australian Charter of Healthcare Rights reinforces this by guaranteeing your right to:
- Clear information about your condition, treatment options, benefits, and risks
- Ask questions and receive answers you can understand
- Accept or refuse any treatment, test, or procedure
- Seek a second opinion from another doctor
- Withdraw consent at any time, even after you initially agreed
Consent must be voluntary — no one can force or pressure you into a medical decision. If you lack the capacity to consent, a legally authorised substitute decision-maker (such as someone with medical power of attorney) may consent on your behalf.
When does it apply?
- Before any medical treatment, procedure, or test — from a blood test to major surgery.
- When a doctor recommends a change in your treatment plan.
- In emergency situations, a doctor may proceed without consent if delay would endanger your life, but must inform you as soon as possible afterwards.
- For children under 18, a parent or guardian generally provides consent, though mature minors may consent for themselves (Gillick competence).
What to Do If You Were Not Given Informed Consent Before Medical Treatment in Australia
- Ask your doctor to explain your diagnosis, the proposed treatment, alternatives, and the risks of each option in plain language.
- Take your time — you are not required to decide on the spot unless it is a genuine emergency.
- Bring a support person to appointments if it helps you understand and remember the information.
- Request written information if verbal explanations are not enough.
- Ask about the consequences of doing nothing so you can weigh all options.
- Put your preferences in an advance care directive so your wishes are known if you lose capacity in the future.
What should you NOT do?
- Don't sign a consent form unless you fully understand what you are agreeing to.
- Don't feel pressured — you always have the right to refuse treatment or ask for more time.
- Don't assume silence is consent — your agreement must be clearly expressed, either verbally or in writing.
- Don't ignore your right to a second opinion — getting another view is a normal part of healthcare decision-making.
How Tasmania differs from federal law
Informed consent for medical treatment in Tasmania is governed by common law principles and specific statutory provisions. Tasmania does not have a single comprehensive consent-to-treatment statute like South Australia, but has important legislation on advance directives and guardianship.
- Under common law, a health practitioner must provide sufficient information about the nature, risks, benefits, and alternatives of a proposed treatment to enable the patient to make an informed decision. Failure to obtain proper consent may constitute assault or negligence.
- The Guardianship and Administration Act 1995 (Tas) provides for the appointment of guardians for people who lack capacity to make medical decisions. The Public Guardian can act as guardian of last resort.
- Tasmania has advance care directive provisions allowing individuals to document their wishes about future medical treatment. The Advance Care Directives Act (proposed) aims to strengthen these protections.
- For children, parents or guardians generally provide consent. Mature minors may have the capacity to consent under the common law "Gillick competence" principles.
