Clayton Utz's Stuart Clark will succeed Mallesons Stephen Jaques' Robert Milliner as chairman of the Large Law Firm Group (LLFG).
Milliner, who will also step down as Mallesons' chief executive partner at the end of the year, held the inaugural role for five years.
"It has been a privilege to work with my colleagues amongst the large law firms on the further development of the Australian legal profession," said Milliner. "I am looking forward to the implementation of the National Legal Profession Reform project after the legislation is passed next year and to the ongoing development of the Law Council of Australia as the peak body representing Australia's lawyers."
The LLFG's principal aim is to push for an integrated Law Council of Australia, as the umbrella organisation for Australia's legal profession, and reform of the national legal profession.
Clark is the chief operating officer and managing partner, international, at Clayton Utz.
"I am pleased to have the opportunity of continuing to pursue the LLFG's reform agenda," said Clark. "Over the coming months the LLFG will be working with government, the profession and the business community to ensure the successful implementation of the national legal profession reform package."
Managing partner Tony O'Malley will represent Mallesons on the LLFG, which also includes Allens Arthur Robinson's Michael Rose, Blake Dawson's John Carrington, Corrs Chambers Westgarth's John Denton, DLA Piper Australia's Tony Holland, Freehills' Gavin Bell, Minter Ellison's John Weber and Norton Rose's Wayne Spanner.
