Since 1994 Mark Walsh has practised as a common law and a commercial barrister appearing for both plaintiffs and defendants in a diverse range of matters. Over 21 years as Junior Counsel and 9 years as Senior Counsel he has appeared regularly as a trial lawyer and at appellate level.

Mark has embraced a team approach to litigation. He recognises that effective outcomes for his matters require ongoing sound communication between the client, the solicitors and counsel. Mark’s approach to his cases and his role as part of the litigation team is captured by his adage: “I take a traditional approach. I act on instructions.” He places great importance on courtesy at all times during the course of litigation, and particularly with opponents.

Over the last 30 years Mark’s areas of practice have been general litigation, medical and professional negligence, commercial disputes, and coronial proceedings. Mark’s study leading to his Bachelor of Dental Surgery in 1980 and his experience as a full-time dental practitioner until 1994 equips him with knowledge and insight into expert evidence involving medical and health issues.

Mark has a particular interest in causation, and practical solutions to “interesting” legal problems. He adopts a case theory approach to litigation to allow the client’s best case to be identified from an early stage of the dispute which allows it to be put at its highest.

Mark enjoys the camaraderie of his fellow legal practitioners, including as opponents, and his role as a mentor for members of the profession. He has served on the Bar Association’s Cost and Fees Committee, including as its chairperson.

Mark also practises as mediator, informed by his long experience of acting for parties in mediations and particularly in many Medical Negligence cases.

Mark has been recognised in Best Lawyers for professional negligence since 2017 and in Doyle's Guide as a recommended senior counsel in Leading Commercial Litigation & Dispute Resolution Barristers – Canberra, since 2020.
