The Wests Tigers have landed their big fish.
Premiership-winning hooker Apisai Koroisau has signed with the club for the 2023 season on a two-year deal with a mutual option for a third season.
The Tigers have also signed Isaiah Papali'i for 2023, while also welcoming Jackson Hastings and Tyrone Peachey to Concord for next year.
The dual premiership winner adds class and experience to a Tigers outfit that is rebuilding with Tim Sheens as the new director of football.
Koroisau won a premiership with the Michael Maguire-coached Rabbitohs in 2014 and with the Panthers last year. He has one year left on his Penrith contract.
"We're very pleased to have secured Apisai from the start of the 2023 season," said Sheens said.
"He not only adds a further level of experience in a key position of the spine, but he has shown himself to be successful alongside head coach Michael Maguire previously in his career.
"It is always a big positive to sign a player with international and State of Origin experience, and what Apisai has achieved at both club and representative level will be a great addition to what we are building here.
"He will join us with a wealth of experience to his name, having represented Fiji on the international stage and the Blues in State of Origin."
