The Brumbies have confirmed four of their stars won't be returning to the side after the Super Rugby Pacific season comes to its conclusion.

There'll be some new faces at the Brumbies next Super Rugby Pacific season, with four key cogs to depart at the end of this campaign.

The club confirmed gun fullback Tom Banks and long-tenured prop Scott Sio along with centre Irae Simone and hooker Folau Fainga'a will be heading off after the final, which kick off for the Brumbies on Saturday night against the Hurricanes.

All four boast Wallabies experience with a combined 114 caps, while they leave 344 games of Brumbies experience behind.

It adds to what will be a big transitional period for the club, with coach Dan McKellar also departing to pick up a full-time role with the Wallabies.

Banks, who's scored 35 tries for the Brumbies, is expected to pick up a Japanese deal worth around $1.4 million a year, while Fainga'a is rumoured to be joining the Western Force.

Simone has been linked with a move to France.

But it's Sio who leaves behind the biggest legacy, having spent 11 seasons with the club in becoming one of just four Brumbies to play more than 140 games.

"It has been a privilege to have Scott as part of the organisation and to see him develop into a leader amongst the group from his time in the Academy to becoming a Wallaby and a world class prop ... he will definitely go down as one of the special players in the history of the Brumbies," chief executive Phil Thomson said.

"Scott, Tom, Folau and Irae have all left a lasting impression in their time at the Brumbies, all playing more than 50 games for the club and we thank each of them for their commitment and contribution to the team both on and off the field.

"The team and the entire organisation are focused on finishing this season together on a high, starting with Saturday's quarter-final against the Hurricanes."
