Euihyuk Brian Byun

Introduction

Euihyuk (Brian) Byun is a former registered nurse in New South Wales whom the NSW Civil and Administrative Tribunal disqualified from being registered as a nurse for two years, with a matching prohibition on providing any health services, after finding proven a complaint that on 20 November 2024 he was convicted of an offence of causing another person to consume food or drink containing an intoxicating substance with intent to harm, and that on 3 July 2023 he made false and misleading statements to the Nursing and Midwifery Council of NSW by stating that he did not use, and had never used, illicit drugs. The Health Care Complaints Commission prosecuted the complaint. The Tribunal found him guilty of unsatisfactory professional conduct and concluded the conviction rendered him unfit, in the public interest, to practise nursing.

Background Information

Byun worked as a registered nurse in New South Wales and was no longer registered by the time the Tribunal decided his case. His regulatory troubles ran on two parallel tracks. The first was criminal: a conviction on 20 November 2024 for causing another person to consume food or drink containing an intoxicating substance with intent to harm — an offence under NSW statute carrying real criminal culpability for secretly drugging a person. The second was dishonesty: statements made to the Nursing and Midwifery Council of NSW on 3 July 2023 denying any use of illicit drugs, which the Tribunal found false and misleading. The Commission prosecuted both strands before the Tribunal.

The Controversy or Incident That Led to Their Cancellation

Tribunal findings. The findings below are the formal adjudications of the NSW Civil and Administrative Tribunal in a case prosecuted by the Health Care Complaints Commission. The criminal conviction is a matter of court record.

It was alleged that on 20 November 2024, Byun was convicted of an offence of causing another person to consume food or drink containing an intoxicating substance with intent to harm. It was also alleged that on 3 July 2023, he made false and misleading statements to the Nursing and Midwifery Council of NSW by stating that he did not use, and had never used, illicit drugs. In its decision of 18 June 2026, the Tribunal found the complaint proven, found Byun guilty of unsatisfactory professional conduct, and concluded he had been convicted of a criminal offence that rendered him unfit in the public interest to practise nursing. Because he was no longer registered, the Tribunal determined that had he still been registered it would have cancelled his registration; instead it disqualified him from being registered in nursing for two years and prohibited him from providing any health services for the same period.

Public Reaction and Consequences

The Health Care Complaints Commission published its media release on 2 July 2026. The disqualification-plus-prohibition structure means that for two years Byun cannot be registered as a nurse anywhere in Australia under the national scheme and cannot provide any health service in NSW, registered or not. After the two years expire he may apply afresh, but any registration application would have to disclose the drugging conviction and the false statements — findings that a fresh application would struggle to overcome. The Commission’s release did not report any public response from Byun.

Current Status

Byun is a former nurse, disqualified from registration for two years by the Tribunal’s decision of 18 June 2026 and prohibited from providing any health services for the same period. The conviction of 20 November 2024 stands on the court record. The Tribunal’s decision is published through NSW Caselaw, and the sources report no appeal.

Impact on Their Career/Life

A nursing career ended at the intersection of a conviction for secretly drugging a person and a regulator’s finding that he lied to his own professional council about illicit drug use — the combination of criminality and dishonesty being the pattern the Tribunal treats as unfitness in the public interest. The case also shows the national scheme’s response to a practitioner who has already left the register: disqualification and a prohibition order in place of cancellation, closing the unregistered-practice route for the same period. Byun’s name is permanently part of the published disciplinary record.
