Rugby Australia’s new chairman, Dan Herbert, says the game’s member unions are committed to a major overhaul to lift the performance of the Wallabies despite rolling his predecessor at the weekend.

But Mr Herbert, a former Wallaby who replaced Hamish McLennan on Sunday night, has left the door open to some changes to a contentious proposal to give more power over the top players and teams to the national governing body, saying the game “requires everyone to unite” before it can be reformed.
