Luke Keary forms a crucial part of the South Sydney side for 2016 according to coach Michael Maguire.

The South Sydney Rabbitohs confirmed on Tuesday that Luke Keary will move on at season's end to another NRL club.

Keary, 24, has played 58 NRL games for the Rabbitohs to date, having risen through the under-20s ranks to make his NRL debut in 2013.

Keary says he wants to finish this season off in the best way possible.

"I want to thank all of the Rabbitohs' Members and fans for their support of me and the team over the past few years," Keary said.

"I've created some fantastic memories at this club and made some life-long friendships as well.

"There is still a job to be done this season and I will be giving my all every time I get the opportunity to wear the Rabbitohs jersey."

Rabbitohs coach Michael Maguire says he's looking forward to rest of this season with Keary.

"Luke has grown as a player and a person within our club during his time with the club and he's enjoyed some great success with this team," coach Maguire said.

"He's committed to finishing this season off with us by putting in his best effort each time he represents the club, he's helped create some great memories here, and we wish him the best of luck with his future career from the end of the season."
