Marion practices in commercial, public and criminal law.

Criminal and public law

Marion accepts briefs to advise and appear in all criminal and public law matters, but has specific expertise in handling complex litigation involving the interplay between the investigatory powers of authorities and public policy.

Immediately before coming to the bar Marion spent seven years working for the Open Society Foundations in London where she led teams of international lawyers on strategic litigation and reform projects on criminal justice, police practices, and prevention and accountability for torture. Her team’s cases spanned the full spectrum of domestic and international courts in Europe, Central Asia and Latin America.

Prior to that time Marion worked for the United Nations on a two-year investigation into genocide and other international crimes at the Extraordinary Chambers in the Courts of Cambodia. Using her legal, analytical and investigative expertise, she built a case into an indictment for trial for senior leaders of the Khmer Rouge.

Marion also lectured in public international law at the University of the South Pacific in Vanuatu, while running an international treaty project for PacLII. 

Commercial law 

Marion accepts briefs to appear and advise in a wide range of general commercial, government, health and aged care, and planning and environment law matters.

Prior to working overseas, Marion practiced as a solicitor at Russell Kennedy in commercial dispute resolution, health and aged care, and government law. She understands many of the practicalities of health law, having worked as an assistant psychiatric nurse while studying law.

Marion has worked in large, multi-national organisations for many years, and understands the legal complexities inherent in commercial dispute resolution for corporations, and the breadth of issues facing in-house and corporate counsel. She is experienced in strategizing and managing large-scale, lengthy litigation with multiple stakeholders.

Marion was the Associate to the Honourable Justice Stuart Morris at the Supreme Court and the Victorian Civil and Administrative Tribunal, providing support in the Planning and Environment List. She has a particular interest in planning, environment, and local government matters, and associated disciplines.

Inquests and Inquiries

Marion accepts briefs to appear in coronial inquests and in professional disciplinary matters. At Russell Kennedy, Marion represented members of Victoria Police and other government departments in coronial inquests. She also dealt with professional disciplinary matters against health practitioners.


Marion holds a Masters of Laws, and a Bachelor of Laws with first class honours, from the University of Queensland. She also holds a Graduate Diploma in International Commercial Arbitration from UQ.

For many years Marion worked as a Senior Legal Reporter for the Federal Law Reports and Federal Court Reports at Thomson Reuters Australia.

Marion is reading with Ben Ihle and her senior mentor is Julian Burnside AO QC.
