Andy Marinos, chief executive of the Rugby Australia national governing body, will leave the role in June.
Marinos, who joined Rugby Australia in February 2021, is making the move to pursue new opportunities.
The governing body says it has already started a recruitment process, with Marinos to remain in his role until mid-June to assist with the transition.
During his two-plus years in charge, Marinos has overseen the organization's financial recovery from the economic downturn caused by Covid-19, jumping from an AUD27.1 million ($18.1 million) loss in 2020 to an AUD8.2 million profit in 2022.
He was also in charge when Australia was formally awarded hosting rights for the men’s 2027 Rugby World Cup and for the 2029 women’s tournament.
Hamish McLennan, Rugby Australia chair, said: “We asked Andy to draw upon his impressive career experience and extensive global relationships to re-establish rugby as a leading code in Australia – he has delivered on this and been fundamental in the turnaround of the business.
“Andy will leave Rugby Australia having delivered several key projects, including the finalization of the 2027 and 2029 Rugby World Cups, locking in the 2025 British and Irish Lions tour, planning for a new contracting model for the professional game, implementation of a strategy to professionalize Women’s XVs rugby, and a new four-year Collective Bargaining Agreement for our professional men’s and women’s players.”
Marinos added: “I cannot overstate the commitment and incredible work ethic of the people around me at Rugby Australia, and the roles they have played in helping drive some critical structural changes for rugby in this country.
“The foundations have been established and the business is now well-prepared to test the market for private equity investment, making it the right time for me to move on.
“I will leave with the knowledge that Rugby Australia is in a stronger position than when I joined, and proud of what has been achieved in my tenure as chief executive.”
Before joining Rugby Australia as chief executive, Marinos had two stints in the same position for Sanzaar, the body that governs top-level rugby union in the southern hemisphere.
Originally from Zimbabwe, he played international rugby union for Wales between 2002 and 2003.
