Cubelli, who joined the club at the start of 2016, will head back to his native Argentina to sign with fellow Super Rugby club Jaguares.

The Argentinean scrum-half made 18 appearances for the club since his debut against the Hurricanes.

Meanwhile, Alcock heads north to Japanese outfit Kamaishi Seawaves following a stellar season for the Brumbies, having joined at the start of the year from the Western Force.

“We would like to thank both Tomas and Chris for their time at the Brumbies,” CEO Michael Thomson commented.

“Both have been outstanding players for the club and have helped foster our culture off the field.”

“While we are sorry to see them both leave the club, we wish them both the very best of luck for the future and they are welcome back at the Brumbies at any time. They will always be part of the Brumby family.”
