End of Life Law in Australia

Section: Legal Overview

Legal Overview

The law at end of life is complex and often difficult to understand. This webpage is designed to help you navigate the laws on this website. It gives an overview of fundamental concepts relating to the law at end of life in Australia.

Links are provided to each topic's webpage for further information. If you are a health professional you can also access free online training modules about these topics at End of Life Law for Clinicians.

Capacity and consent to treatment

Every adult has the right to decide what is or is not done to their body. For medical treatment to be lawful, a person must consent to it. If that treatment is given without consent, the health professional who provides it may be civilly and criminally liable. An exception to this is if the treatment was provided in an emergency in order to save the person’s life, and it was not possible to obtain consent from the person or their substitute decision-maker.

Consent to treatment is only valid if the person has capacity or is competent to consent. The person's consent must be given freely and voluntarily, and it must relate to the proposed treatment.

Every adult is presumed to have capacity to make their own medical treatment and health care decisions. To have capacity the person must be able to comprehend and retain the information needed to make the decision, including the consequences of the decision; and use and weigh that information as part of their decision-making process.

A person without those abilities, due, for example, to dementia, intellectual disability, acquired brain injury or mental illness will have impaired capacity for medical decision-making and will not be able to make medical treatment decisions themselves. In that situation, there are three ways in which decisions can be made by, or for them:

  • Before they lost capacity, the person may have made an Advance Care Directive which provides directions about medical treatment;
  • A substitute decision-maker can make the decision, based on what they believe the person would have wanted and their best interests; or
  • A tribunal or the Supreme Court can provide consent, or make a treatment decision.

Adults and end of life decision-making

Advance Care Directives

An Advance Care Directive is an instruction that a person makes now in the event they lose capacity in the future to make decisions about their medical treatment or health care. There are two types of Advance Care Directives: common law Advance Care Directives governed by the common law (i.e. law made by decisions of courts), and Statutory Advance Care Directives governed by State and Territory legislation.

Advance Care Directives can be used to communicate specific instructions about types of treatment, including to request or refuse treatment (e.g. refusing a blood transfusion or cardiopulmonary resuscitation), or to communicate values and preferences about care or treatment (e.g. wanting to die at home, not in hospital). Some Advance Care Directives can also be used to appoint a substitute decision-maker.

Generally, health professionals must follow a valid and applicable Advance Care Directive (including a directive that refuses life-sustaining treatment) except in some limited circumstances. They may be liable under civil and criminal law if they do not.

Guardianship and substitute decision-making

If a person cannot make their own medical treatment decision because they have impaired capacity, and they do not have an Advance Care Directive, someone has to decide for them. For adults, guardianship legislation in each State and Territory allows someone else (e.g. a spouse, family member or friend; a statutory body such as the Public Guardian or Public Advocate; or a court or tribunal) to be the substitute decision-maker for medical treatment.

Withholding and withdrawing life-sustaining treatment from adults

It is lawful for an adult with capacity to make their own decisions to consent to or refuse medical treatment, even if the decision they make results in their death. Health professionals must respect a person's decision to refuse treatment, and, if directed to do so can legally withhold (not start treatment) or withdraw (stop treatment already started) life-sustaining treatment from adults, even if this might result in the person’s death. It can also be lawful for a substitute decision-maker to ask that life-sustaining treatment be withheld or withdrawn from someone who can no longer make treatment decisions for themselves.

Individuals, families and substitute decision-makers cannot demand treatment that health professionals consider to be futile (e.g.  treatment that a health professional believes would not be beneficial to the person). A health professional has no legal obligation to provide such treatment, and generally can withhold or withdraw futile or non-beneficial treatment without consent from an adult or their substitute decision-maker (except in Queensland, where a substitute decision-maker’s consent is required).

Children and end of life decision-making

Consent is required before medical treatment can be provided to a child under the age of 18, unless it is an emergency or a blood transfusion is required. Upon reaching 18 (and 16 in South Australia) that person will be able to make their own decisions about medical treatment.

Generally, when a child is under 18 the child’s parents can consent to or refuse medical treatment for their child. However some older children may be able to make their own medical treatment decisions. This is the case if they have ‘sufficient understanding and intelligence to understand fully’ the proposed medical treatment and its effects (this is sometimes referred to as being Gillick-competent).

The paramount consideration of parents (and courts) when making treatment decisions is what is in the child’s best interests. Parents, and children who are Gillick-competent are able to refuse life-sustaining medical treatment, provided it is in the child’s best interests.

Palliative medication

Palliative medication is often given to a person with a life-limiting illness who may be experiencing pain or symptoms to maintain or improve their comfort. In some cases, this medication may have the unintended effect of hastening the person’s death. If this occurs, the person who provided the medication (usually a doctor or nurse) will not be liable for the person’s death so long as their primary intention was to relieve pain or symptoms, and not to hasten death.

This legal protection of appropriate palliative medication is part of Australian common law, and is known as the doctrine of double effect. Some Australian States and Territories have incorporated double effect into legislation.

Organ and tissue donation

Families and friends of people who are dying or who have recently died may be asked to consider donating the deceased’s organs and tissues for transplantation into another person. Consent is needed for organ and tissue donation. In Australia, adults with decision-making capacity have the option to record their consent or refusal to donate on the Australian Organ Donation Register. However, depending on the State or Territory, the deceased’s family may be asked to consent to donation, even if the person has already recorded their consent on the Register. In all jurisdictions except Victoria there must also be no objection by the deceased's  senior next of kin, or another next of kin to the removal of tissue.

Where there is a dispute or resistance to organ donation among family members, removal of organs or tissue will not occur, even if the potential donor had expressed a wish to donate, or had registered their consent.

Euthanasia and assisted dying

Voluntary assisted dying (VAD) (euthanasia and assisted dying) refers to the assistance provided to a person by a health practitioner to end their life. VAD is lawful in Victoria in limited circumstances. VAD is unlawful in all other Australian States and Territories but will commence in Western Australia on 1 July 2021.

In Australian States and Territories where VAD is illegal anyone who assists another person to die may be charged with murder, manslaughter or assisting suicide.

These acts are legal in some countries, but whether or not it is lawful for Australians to accompany a person to travel overseas to receive assistance to die has not yet been decided in Australia.

A health professional does not assist dying or unlawfully kill a person by withholding or withdrawing life-sustaining treatment that has been lawfully refused by the person or their substitute decision-maker. This is also the case where the health professional does not provide or withdraws treatment that is futile or burdensome. Providing palliative medication which ultimately hastens death is not assisted dying, so long as the health professional’s primary intention in giving the medication was to reduce pain or symptoms, not cause or hasten death. It is also lawful for a person to refuse food and drink (either naturally or through artificial measures such as a tube) even if that results in death.
