Wayne Bennett has already pulled off a win for South Sydney, with NSW hooker Damien Cook agreeing to stay at the Rabbitohs until the end of the 2023 NRL season.

Cook received an upgraded contract for 2019 and re-signed for another four seasons in a deal reportedly worth $4.5 million.

Former Brisbane mentor Bennett said re-signing Cook was a priority when he arrived to start his three-year Rabbitohs stint on Tuesday.
