Paul McLean is the new interim RA chair.
McLean's appointment will allow the next chair - who will be one of three new directors appointed at next month's AGM - to transition into the role in the near future.
"With Clyne to step down from the board at the AGM and several key projects underway,the board has made the change to enable the incoming director to gain an understanding of the people and key projects across the game before transitioning to chair,"a statement read.
McLean is one of the more senior directors on the board,having started in the role eight years ago. He was also RA president from 2005 to 2009 and is a member of the RA Hall of Fame.
"The board has collectively made the decision to make this change,with the full support of Cameron,to enable us to provide support and a comfortable transition for the new chair following the AGM,"McLean said via a RA statement.
"As the most senior director remaining on the board during the AGM,I have accepted the chairmanship during this transitional period."
McLean,who is a Queensland Rugby Union life member having played 100 games for Queensland and 31 Tests for the Wallabies in a decorated career,has built an illustrious business career since the end of his playing days in 1982.
He said the interview process for the next chair had already started and included some high quality candidates.
