South Sydney have signed Test forward Jaydn Su'A until the end of 2021 following his release from the Broncos.
Su'A will join the Rabbitohs immediately after having played 31 NRL matches since making his debut for Brisbane in 2016.
The 21-year-old will be available for selection in for South Sydney's Round 17 clash with Manly.
Rabbitohs General Manager of Football Shane Richardson said the club had been chasing Su'A for over a year.
"Jaydn has been on our radar for over 12 months now and we're excited to see him pull on the red and green jersey of South Sydney," Richardson said.
"He has had raps on him since making his NRL debut as an 18-year-old due to his strong work ethic and his tough defensive capabilities.
"He's stepped up to the international stage now and I'm sure he will play a lot more representative football throughout his career."
