The former world cup winning All Black Brad Thorn is to replace Nick Stiles as coach of the Queensland Reds.
The Queensland Reds chief executive Richard Barker said Thorn had been appointed to bring about a "change in culture, discipline and standards."
Under Stiles, a former Queensland prop, the Reds won just four games in the Super rugby competition this year.
Speculation has been rife for several week that that Stiles would be sacked after reported run-ins with fellow coaches and key Queensland Rugby Union administrators, having guiding the Reds to just four wins in his first season at the helm.
"Queensland Rugby Union was disappointed with the performance of the St.George Queensland Reds in 2017 and we believe we require a catalyst for change in culture, discipline and standards," said Barker.
"We feel strongly that Brad Thorn is the right person to lead this change and that his appointment as head coach is the necessary catalyst for that change.
"Brad has a proven track record of success as both a player and a coach. He is without peer when it comes to the culture and professionalism required to be successful at the highest level of our sport and he is enthusiastic about moving the Reds forward and creating a winning culture at Ballymore once again.
Thorn has already experienced success within Queensland Rugby's pathway programs, guiding the Queensland U20s to two Super U20 Championship titles as an assistant coach in 2016 and as head coach to an undefeated season in 2017.
Thorn joined the QRU in late 2015 as Queensland Elite Development Squad forwards coach, after retiring from playing both international rugby league and rugby union.
"I believe actions speak louder than words. I've been grateful for the opportunity to spend the last two years at Ballymore coaching the Queensland Under 20s, Queensland Country and the Reds," said Thorn in a statement.
"I feel I'm contributing to a change in culture and standards in those teams and I look forward to continuing to contribute to this organisation and the success of the Reds."
