Exeter Chiefs have signed Mitch Lees from London Welsh on a two-year deal.
The back-row, who moved to England at the start of the season from his native Australia, follows Tomas Francis in signing for the club.
After finalising his deal at the Aviva Premiership side, Lees told the club's official website: "I'm really excited by the move. I've had a great season with London Welsh and really enjoyed my time there, but moving to the Chiefs is an opportunity I couldn't turn down.
"This is only my second year as a professional player, so this move has come a lot earlier than I imagined it would have done. Exeter are a great club, one of the top sides in England, so to get the chance to come to play for them is a big thing for me."
The Exiles are currently ninth in the league table.
