Fair Work Commission president Iain Ross has resigned after more than a decade in the role.
Justice Ross had been a tribunal member for more than 25 years before nearly 11 years as president, but will call time from November 18.
He said it was the right time to hand over the role given the organisation was meeting all performance targets and its digitalisation strategy was on track.
"We are in good shape as an institution and are well placed to successfully implement any legislative change determined by parliament," he said in a statement on Monday.
"Leaving now will mean whoever is chosen as my successor will be fully involved in the implementation of those changes from the outset, rather than splitting that responsibility between myself and the next president.
"It is in the interests of the institution that there is continuity of leadership through the implementation of any legislative change.'
Workplace Relations Minister Tony Burke thanked Justice Ross, praising his "great intellect and integrity".
Mr Burke pointed to a number of his achievements in the role, including minimum hourly rates of pay for fruit pickers, the groundwork for 10 days of family violence leave and the recent 5.2 per cent rise for the low-paid.
"His commitment to fairness, decency and justice hasn't wavered in his 10 years on the commission," he said.
"His open and transparent approach has been an enormous asset – working in the interests of both workers and employers.
The Fair Work Commission is an institution the Australian people rely on and trust. As president, Justice Ross has cemented that trust."
Mr Burke said the role of the commission has never been more important given the inflation crisis facing the nation.
An interim president will be appointed shortly.
