Rabbitohs forward Cameron Murray.

South Sydney have secured the signatures of two of their rising stars with Cameron Murray and Campbell Graham extending their tenure at the club until the end of the 2021 season.

The products of the South Sydney Juniors system were integral parts of the Rabbitohs' charge to the finals last season.

Murray, 20, captained the NSW under 20s side in 2017 after previously leading the state at under-18 level. He has also worn the green and gold for the Junior Kangaroos and Australian Schoolboys.

Graham, 19, has played 21 Telstra Premiership games since making his first-grade debut against the Dragons at the Sydney Cricket Ground in 2017.

He represented the Australian Schoolboys for two years, co-captaining the side in 2017
alongside Dragons player Zac Lomax.

"Both Cameron and Campbell have shown they have what it takes to become regular NRL players and also to perform at the highest representative levels of the game in time," South Sydney general manager of football Shane Richardson said.

"Cameron is a workhorse and has made an impact on our team from the moment he was selected in first grade.

"His work ethic is second-to-none; he has the respect of his teammates, coaches and staff; and is a young leader amongst our squad.

"Campbell is still eligible for the under 20s but his efforts in the NRL have seen him earn a spot in our backline over the past 18 months."

Murray says he could not be happier about re-signing with the Rabbitohs.

"I'm really happy to know I'll be here for at least the next three years, playing for the club I grew up supporting, the club my father played for and the club I was born into," Murray said.

"This club has a very bright future and I'm really excited to be playing under the administration we have here at Souths."

Graham said "there are definitely exciting times ahead" at Souths.

"I definitely see my future here at this club," Graham said.

"I'm really happy with my progression over the past few seasons and I'm really grateful for the opportunities the club has provided for me to start my career."
