The habit that separates a prepared Australian applicant
Before answering any Australian ethics question that touches voluntary assisted dying, abortion, mental health detention, guardianship or child protection, ask yourself one question: is the answer Commonwealth or state? Australia is a federation, and health law is largely made by the states and territories. Overseas material will point you at regulators and consent tests that have no application here.
Applicants who say “the law in Australia is…” about a state-variable topic mark themselves out. Applicants who say “this is state legislation and it differs — in Victoria, for instance…” sound like people who have actually read something.
The four principles, and the Australian accent on justice
The principles are not ranked. Ethics is the work of adjudicating the conflict between them in a specific case — reciting them and stopping is not an answer.
Beneficence and non-maleficence
The obligation to act for the patient’s benefit, and to avoid disproportionate harm. Almost no intervention is purely one or the other — chemotherapy poisons to cure, surgery injures to repair — so the clinical question is whether the harm is proportionate and whether the patient agrees it is worth it.
Justice
Fairness in the distribution of benefits, burdens and access — and the principle Australian medical ethics weights most heavily.
- Why justice carries more weight here
- Two structural reasons that show up in interviews constantly. Geography: Australia is one of the most urbanised countries in the world with one of the largest and most sparsely populated interiors, and health outcomes track distance from a capital city with brutal consistency. And the health gap between Aboriginal and Torres Strait Islander peoples and other Australians, which is the defining justice question in Australian health care.
Rogers v Whitaker: the case every Australian applicant should know
In Rogers v Whitaker (1992) 175 CLR 479, the High Court of Australia considered a patient who underwent elective eye surgery and developed sympathetic ophthalmia in her good eye, leaving her almost totally blind. She had asked repeated questions about complications. The risk was roughly 1 in 14,000 and had not been disclosed.
The High Court held the surgeon liable and rejected the practitioner-centred approach to disclosure — the idea that adequacy is judged by what a responsible body of medical opinion would have disclosed. Australia adopted instead a patient-centred standard of material risk: a risk is material if a reasonable person in the patient’s position would be likely to attach significance to it, or if the practitioner is or should reasonably be aware that this particular patient would.
The five elements of valid consent
Capacity; disclosure of the diagnosis, the procedure, material risks, reasonable alternatives and the consequences of doing nothing; understanding, which is why teach-back beats “any questions?”; voluntariness; and authorisation. Consent is a process, not a form; it is decision-specific; and it is revocable at any time.
- A specifically Australian point
- Consent obtained through a family member acting as interpreter is frequently not valid consent, and with TIS National and state health interpreter services available there is rarely a good excuse. Raising this in a consent station is a strong move.
Capacity, and why there is no single Australian Act
Capacity is a clinical judgement, decision-specific and time-specific, presumed in adults, and not the same as agreeing with your recommendation. The four functional elements are communicating a choice, understanding, appreciating how it applies, and reasoning against your own values. Australia has no one national capacity statute — capacity, guardianship and substitute decision-making sit in state and territory legislation, administered by tribunals such as VCAT, NCAT and QCAT.
Marion’s Case and mature minors
Secretary, Department of Health and Community Services v JWB and SMB (1992) 175 CLR 218 established that a minor may consent where they achieve sufficient understanding and intelligence to comprehend fully what is proposed — the mature minor principle, referred to in Australian practice as Gillick competence. It also established that certain “special medical procedures”, such as non-therapeutic sterilisation, fall outside parental authority altogether and require court authorisation.
Privacy, My Health Record and breaking confidentiality
Australian health privacy is governed principally by the Privacy Act 1988 (Cth) and the Australian Privacy Principles, with health information treated as sensitive information attracting higher protection, layered with state health records Acts and the professional obligation in Good Medical Practice.
- My Health Record is the national digital health record, which moved to an opt-out model in 2018 — a decision that generated substantial debate about consent, secondary use and law enforcement access.
- The Notifiable Data Breaches scheme requires notification where a breach is likely to result in serious harm; the Medibank breach is the reference case.
- Mandatory reporting of child abuse and neglect is state legislation and differs in who must report and what must be reported.
- Notifiable diseases are reported under state public health Acts.
- The Australian Privacy Principles permit disclosure where necessary to lessen or prevent a serious threat to life, health or safety.
Voluntary assisted dying across Australia
This is the topic most likely to come up in an Australian ethics station, and Australia’s position is genuinely distinctive: it has moved from complete prohibition to near-national legalisation in under a decade.
Voluntary assisted dying is lawful in every Australian state, following Victoria (the first, operating from 2019), Western Australia, Tasmania, South Australia, Queensland and New South Wales. The Australian Capital Territory’s laws commenced in November 2025. The Northern Territory remained the only jurisdiction without a scheme, having announced in early 2026 that it would introduce a bill.
The common architecture
An adult with decision-making capacity, acting voluntarily and without coercion, with an eligible advanced and progressive condition that will cause death, suffering intolerably, and satisfying a residency requirement. Typically three requests including a written declaration, assessment by two independent practitioners with mandatory training, and a review body.
The differences are the examinable part
Most states require a prognosis of six months, or twelve for neurodegenerative conditions. The ACT imposes no prognostic timeframe at all, and uniquely permits a nurse practitioner to be one of the two assessing practitioners. Several states restricted practitioner-initiated discussion of VAD, which drew criticism for impeding informed decision-making. Telehealth provision is complicated by Commonwealth Criminal Code provisions on using a carriage service in relation to suicide — a genuine federal–state conflict worth mentioning.
- A piece of history almost no applicant has
- The Northern Territory legalised euthanasia in 1995 — the first jurisdiction in the world — and the Commonwealth overrode it with the Euthanasia Laws Act 1997, which also stripped the territories of the power to legislate on the subject. That restriction was repealed in 2022, which is why the ACT and NT could only begin their processes afterwards.
Aboriginal and Torres Strait Islander health and cultural safety
This is the most important justice topic in Australian medicine and it will come up. The gap in life expectancy, chronic disease burden and avoidable hospitalisation is caused by dispossession, the Stolen Generations, intergenerational trauma and ongoing structural determinants — housing, food security, remoteness, income — together with racism within the health system itself. It is not caused by anything intrinsic to the people affected.
- ACCHOs — Aboriginal Community Controlled Health Organisations — are community-governed primary health services represented nationally by NACCHO. They exist because mainstream services were not delivering, and community control is the point rather than a detail.
- The National Agreement on Closing the Gap (2020), negotiated with the Coalition of Peaks, restructured the approach around shared decision-making, building the community-controlled sector, transforming mainstream institutions, and Indigenous data sovereignty — because the earlier top-down model had failed.
- Discharge against medical advice is best understood as a service failure rather than a patient failure: driven by prior experiences of racism, cultural isolation, distance from family and Country, language and fear. The clinical response is to involve an Aboriginal Liaison Officer or Aboriginal Health Practitioner, ask what would make staying possible, and make it safe to come back.
- Say “Aboriginal and Torres Strait Islander peoples”. Do not treat it as one homogeneous culture; there are hundreds of distinct nations and languages. Do not claim expertise you do not have.
Mandatory notification: the distinctively Australian duty
This is the single most examinable professionalism topic in Australia, and one that candidates who prepared on overseas material reliably get wrong. Under sections 140–141 of the Health Practitioner Regulation National Law, registered health practitioners have a legal duty — not merely an ethical one — to notify Ahpra if they form a reasonable belief that another practitioner has engaged in notifiable conduct.
- Practising while intoxicated by alcohol or drugs.
- Engaging in sexual misconduct in connection with practice.
- Placing the public at risk of substantial harm because of an impairment.
- Placing the public at risk because of a significant departure from accepted professional standards.
The 2020 amendment, and why it is the ethically interesting part
The National Law was amended in 2020 to raise the threshold for treating practitioners: a doctor treating another doctor as a patient must now form a belief of substantial risk of harm before notifying. The change was made explicitly because fear of notification was deterring unwell practitioners from seeking help, and Western Australia exempts treating practitioners altogether. It is a deliberate trade-off in which the legislature accepted slightly less reporting in exchange for more practitioners seeking treatment.
A structure for any impaired-colleague station
Patient safety first if there is immediate risk. Check your facts and separate observation from inference. Speak to the person directly where it is safe. Escalate — supervisor, director of clinical training, or Ahpra where the mandatory threshold is met. Document. And support them: impairment is usually illness, and Doctors’ Health Services funded in every state exist precisely for this, which turns the answer from “ending a career” into “getting a colleague help”.
- The two failure modes
- Covering for a friend, and going straight to Ahpra without speaking to anyone. Both are fatal, and they are opposite errors.
Frequently asked questions
Rogers v Whitaker (1992) 175 CLR 479 established that a risk is material if a reasonable person in the patient’s position, if warned, would be likely to attach significance to it, or if the practitioner is or should reasonably be aware that this particular patient would. It is a hybrid objective and subjective test judged from the patient’s position rather than the profession’s, and it is the foundation of Australian informed consent.
