Board Members

Mr Michael Halliday (Chair)

Magistrate Halliday was with the Queensland Magistracy for 11 years with his appointment as a magistrate on 16 June 1997. He served as magistrate at Brisbane, Dalby, Oakey, Chinchilla, St George, Taroom and Petrie. He was full-time Coroner at Brisbane for almost two and a half years.

At his valedictory ceremony, attended by over 140 people, the Court and legal profession reflected on Magistrate Halliday’s 40 years’ service in the law – a career that took him from articled clerk in Melbourne to barrister in Queensland where he was a barrister in private practice, a Crown Prosecutor, a part-time lecturer in law at QUT and a member of a number of administrative tribunals.

During his legal career Michael developed a keen professional interest in medico-legal issues, he became involved with the ethical education and training of the nursing and legal professions and he took interest in mental health issues especially in so far as they affected youth.

Michael, who throughout his legal career has seen the prevalence and ravages of mental health in our society has joined the Board of Clear Thinking Qld in order to offer some contribution towards the welfare and rehabilitation of young persons who are unfortunately afflicted with mental illness, an ever-increasing ailment in our present society.

Michael has been married to Anne for 46 years and they have 4 adult children and 3 grandchildren.
