Williamson joins Clayton Utz after 12 years as a tax partner with Allens. Her experience also includes six years at PricewaterhouseCoopers and spans income tax, capital gains tax, GST, stamp duty and general tax disputes. She has represented a range of Australian and international clients including BHP Billiton, ANZ, Brown Brothers and eBay. A member of a number of professional organisations, Williamson will take up the position of president of the Taxation Institute of Australia in 2008.

Clayton Utz managing partner in Melbourne, Brad Vann was enthusiastic about the appointment. “We are pleased to welcome a lawyer of Williamson’s standing and talent to the firm,” Vann said.

Head of Clayton Utz’ national tax practice, Sydney-based partner Allan Blaikie, said Williamson joined a mature and substantial tax team. “Our Sydney practice is long-established and we are pleased to be able to build on that capability in Melbourne, with Sue joining the excellent Niv Tadmore,” Blaikie said.

Dr Tadmore, who heads the Melbourne tax practice, said he looked forward to working alongside Williamson and that her “arrival will strengthen the team’s ability to provide clients with outstanding advice in relation to their transactional, ongoing and contentious tax affairs”.
