31-year-old Goodwin had signed a two-year deal with the Leigh Centurions back in June commencing in 2018.
But after losing to the Catalans Dragons “Million Pound Game” on the weekend, the Leigh club has been relegated from the Super League.
“We approached Leigh with an offer and fortunately they accepted,” said Warrington chief executive Karl Fitzpatrick.
“Bryson has got outstanding leadership qualities both off and on the pitch and will be a real asset to the team and culture we want to create. His reputation in the NRL is first class and with his international experience, he’ll add real value to the club.”
“I’ve only heard really good things about Warrington from past players who have played at the club. I also spoke to Sam Burgess and he only had good words to say too. Everyone knows it’s a big club and I’m looking forward to joining,” Goodwin added.
“I really like the Super League; I’ve been watching a lot of it recently since I signed over there and from what I’ve seen it’s a really good competition and is getting better and better every year. The quality is high and am looking forward to playing in it.
“I’ve played a fair bit now so I will look to bring that experience and hopefully add something in both defence and attack, and play some good football.
“I’m looking forward to meeting the players and staff at Warrington and getting to know the members and fans of the club too, and then ripping into training. With a new coach to come on board as well it’s a fresh start for Warrington which is good.”
