Mr Williams is an Enrolled Barrister and Solicitor of the High Court of New Zealand and the Supreme Court of Victoria, who was first admitted to practice in 2005.

In 2003 and 2004 he served on the University of Melbourne’s Trusts and Legislation Committee, which oversaw the governance of the University’s trusts of endowment.

He is a member of the Victorian branches of the Society of Trust and Estate Practitioners (STEP) and the International Fiscal Association. He specialises in trusts and international tax.

He has facilitated the establishment of, and acted as trustee in relation to, over 200 trusts since 2007. 

In the professional world of silo-ed niche specialists, Mr Williams has retained his generalist instincts, maintaining through research and wide reading a macro, global perspective.

He has considerable experience and expertise in international tax and cross border matters, and has worked extensively with trans-national private clients – attending to their cross border corporate and commercial, asset protection and estate planning needs.

With this professional grounding, Mr Williams recognized the strengths of a broader multi-disciplinary approach to problem solving and the provision of more incisive advisory and corporate services.

In April 2014 he assembled a team of international subject matter experts, founding Williams Colebrook to combine the insights of management consulting with traditional trust and company service provision.
