Toulouse have confirmed that Australia international Rory Arnold will be joining the Top14 club at the end of the World Cup next year in Japan.
Arnold has been an integral part of Brumbies since making his debut for the Super Rugby club in 2015 and another season with them in the next season will ensure he can feature for the Wallabies in the 2019 World Cup as it falls under the same calendar year.
However, his move to France will effectively end his Test career as Australia currently have a policy of selecting only players with 60 or more Tests if they are plying their trade overseas.
Brumbies chief executive Phil Thomson wished Arnold good luck for his new stint in France and is confident of him signing off with a strong performance in the upcoming Super Rugby season.
"Rory has the made the decision that he feels is best for the longevity of his rugby career," said Thomson.
"We would like to extend our best wishes to Rory and thank him for his commitment to the Brumbies for the past four seasons.
"We are looking forward to him performing strongly for us during the 2019 Super Rugby season."
The 28-year-old's Test debut for the Wallabies came in 2016 and has so far featured in 19 Tests before he fractured his eye socket in training that cut short the end of the year tour for Michael Cheika's men.
"It was a very hard decision to make. I believe the timing is right to move on after this season and experience something new," said Arnold, who declined contract from a French club in 2016.
"Now that I've made my decision, I'm looking forward to the 2019 season and the future."
