Kyle Godwin will link up with Brumbies in 2017, the Super Rugby outfit announced on Wednesday.
Godwin signs from Western Force on a two-year deal, having spent five seasons in Perth.
The 24-year-old Zimbabwe-born centre made 52 appearances in the competition before signing on with Brumbies.
"The opportunity to grow as a person and as a rugby player at the Brumbies is something I could not ignore," Godwin said.
"The opportunity to be coached by Stephen Larkham, someone who played in a position similar to me was definitely another reason for the decision.
"I've loved every minute at the Western Force and the club will always be very special to me, but the move to the Brumbies is the best decision for my career.
"I've lived in Perth my whole life, I live 10 minutes away from training so it's going to be a big change moving to Canberra but I need a change to keep pushing me and challenging me."
Godwin could make his Australia debut in the Rugby Championship, and he is currently in camp with new coach Larkham.
"We are very pleased he has agreed to join the Brumbies. He's risen through the ranks of WA Rugby and we know how hard the decision for him to leave has been," Larkham said.
"He wants to take his game to a new level and believes the move can help him do that.
"He's played 52 Super Rugby matches for the Force and has developed into an international-standard player in that time.
"We were looking for someone who has strengths in both attack and defence. Kyle possesses those skills as well as great game vision and a powerful running game.
"It will be an exciting time for us when he joins our backline next season."
