Mat Rogers will go back to rugby league after the 2007 World Cup.
The Waratahs and Wallaby utility back is set to sign a R3 million, two-year deal with the Gold Coast Titans.
The move is set to be confirmed on Wednesday at a media conference.
Before switching to union in 2002, Rogers was rated as one of the finest league fullbacks of his generation playing seven Tests for Australia.
The ARU were diplomatic about the loss of one of their star players.
“I respect his right to make a decision about his future,” ARU chief executive Gary Flowers told the Daily Telegraph. “It’s in the best interests of himself and his family. It is post-World Cup. He has been a great Wallaby and I wish him all the best for the future.”
