Brumbies head coach Stephen Larkham will leave the club following the 2017 Super Rugby season to take up a full-time role with Australia.
Larkham, a two-time Super Rugby winner with the Canberra side as a player, has combined his post at Brumbies with a position as attack coach for the Wallabies since 2015.
Following the conclusion of next year's southern hemisphere competition, the 42-year-old will switch solely to the national team on a three-year deal.
"I wanted to ensure I was comfortable with the decision and that both my family and Brumbies had plenty of time to plan for the future beyond 2017," Larkham said in a statement.
"It will be hard to leave, but it's the right time and the best decision for myself and my family and will help me achieve the goals I set out when I began coaching.
"Juggling both roles has been difficult. Ultimately, I wanted to be able to focus my energy on one program and connecting with the Wallabies full-time through to the 2019 World Cup and beyond allows me to do that.
"The Brumbies will always be my home and it is going to be extremely hard to say goodbye at the end of the 2017 Super Rugby season, but I think it is the best decision for both the club and myself."
Larkham wants to help find a suitable successor the 2018 campaign and hopes to be able to rely on the full backing of the fans in his final season.
He continued: "I'll be doing everything I can to support the club in its recruitment of a new head coach and know the right people will be in place to lead this side in the future.
"I am extremely proud of what we have been able to achieve in my time as a coach with the Brumbies and hope the fans will rally behind the side in 2017 and beyond."
