What Derwent & Tamar Chambers does
Derwent & Tamar Chambers is a private barristers' chambers collective based at 128 Macquarie Street, Hobart, Australia — housed in Hobart's first gaol building — that comprises 17 independent barristers practicing across approximately 17-22 areas of law including family law, criminal law, commercial litigation, environment and resources law, building and construction, personal injuries, administrative/public law, and workers' compensation. The chambers markets itself as "Tasmania's finest lawyers" and includes Senior Counsel (Chris Gunson SC) and King's Counsel (Michael Roberts KC) among its members, with barristers regularly appearing in the Supreme Court of Tasmania, Federal Court of Australia, High Court of Australia, and various tribunals.
The chambers operates on the traditional Australian barrister referral model: barristers are instructed ("briefed") by solicitors and law firms, Legal Aid commissions, government departments, and a small share of direct clients. The collective itself does not run a proprietary technology platform; it uses standard legal practice management tools, and its core "product" is courtroom advocacy, advisory work, arbitration, and mediation delivered by individual barristers.
Revenue is generated entirely through professional services fees — brief fees, daily or hourly rates, and fixed fees for specific matters — negotiated individually between each barrister and their instructing party. The chambers entity itself does not centralise revenue collection; barristers are self-employed practitioners who share chambers facilities and administrative support (including a shared reception, phone system, and digital presence via the chambers website). Customer segments span individuals and families (family, criminal, personal injury), corporate and commercial entities (commercial litigation, construction disputes, class actions), government departments and agencies (royal commissions, statutory litigation, public inquiries), and insurers and litigation funders (insurance defence, workers' compensation). Notable recent engagements include representation of the Commonwealth before the Royal Commission into Defence and Veteran Suicide (2021-2024), Counsel Assisting the Royal Commission into Violence, Abuse, Neglect and Exploitation of People with a Disability, lead counsel for MONA in the 'Ladies Lounge' discrimination case, and counsel for Crown Resorts in the Casino Royal Commission.
